Hear Ye! Directional Sound Enabled by Superfast Neurons


first_img(Visited 14 times, 1 visits today)FacebookTwitterPinterestSave分享0 How can you tell where sounds come from?  The brain is quicker than the speed of sound between your ears.There’s only about 8 inches between your ears (more, perhaps, for fatheads).  The speed of sound is finite.  The tiny time lag between the arrival at one ear compared to the other is what enables us to sense the source direction of the sound, but there’s more to it than that.  If signals did not get processed in the brain faster than the time lag, the information would not be useful.Science Daily asks, “How Do We Locate the Spatial Position of Sounds? Mechanism Responsible for Creation of Giant Synapses Discovered.”  Sure enough, there are massive hubs or neural intersections in our brains that can process information faster than the speed of sound.  Here’s the upshot (notice the astonishment):Humans and most mammals can determine the spatial origin of sounds with remarkable acuity. We use this ability all the time — crossing the street; locating an invisible ringing cell phone in a cluttered bedroom. To accomplish this small daily miracle, the brain has developed a circuit that’s rapid enough to detect the tiny lag that occurs between the moment the auditory information reaches one of our ears, and the moment it reaches the other. The mastermind of this circuit is the “Calyx of Held,” the largest known synapse in the brain. EPFL scientists have revealed the role that a certain protein plays in initiating the growth of these giant synapses.Because it resembles the calyx of a flower, anatomist H. Held described it as such in 1893.  Regarding it, Wikipedia says, “This structure is specially designed for fast, efficient transportation of information from one cell to the next.”  The part of the brain that processes auditory information has a number of these structures.According to the Science Daily article, studies at the Ecole Polytechnique Fédérale de Lausanne (EPFL) show the Calyx of Held to act “almost like peer-to-peer communication between neurons.”  These synapses have hundreds of inputs.  “The result is that information is processed extremely quickly, in a few fractions of a millisecond, instead of the slower pace of more than 10 milliseconds that occurs in most other neuronal circuits.”EPFL scientists identified a protein named BMP that is implicated in developing the contact points for the Calyx of Held.  “The impact of this study will go well beyond increasing our understanding of the auditory system,” the article says.  “The results suggest that the BMP protein plays an important role in developing connectivity in the brain.”Medical Xpress begins with an image of the giant synapse.“The brain has developed” this circuit.  Funny; did you ever ask your brain to do that?  There’s another example of pulling off evolutionary magic by misdirection.In his excellent book, The Wonder of Man (1999), Dr. Werner Gitt provided numerous amazing details about our senses.  The ear, “our highest precision sense organ,” is able to detect energy ratios of one million million to one, an “astonishing feat” that approaches auditory perfection.  Since each ear provides two sound paths, we actually get four inputs for localizing sound sources.  Considering the path lengths and the speed of sound, the brain must be able to process inputs arriving as close as 0.00003 seconds apart.  “In acoustic orientation terms this means that a sound source located only about 3° from the centre line of the head is recognized as being off-centre,” he said.  The slight difference in sound intensity between the two ears also gives us information on the distance to the sound.Dr. Gitt’s book, though 14 years old, is highly recommended if you can find it.  It’s well illustrated and extremely interesting.  Not only does he provide a wealth of information about the senses and other body organs, he gives the glory not just to an unspecified designer, but to the Lord Jesus Christ.  [Note: None of the secular sources in this entry dared mention their idol, Charlie.]  The power of the Christian explanation for the wonders of creation is in the details that this book so beautifully presents.last_img read more


Popband Ponytail Holders – Very good no-tangle Ponytail Holders


first_imgThese are nicer than standard hairbands, and that’s the full position. In essence a tied strip of gentle, a little bit shiny elastic, they’re in neutral colours which are nicely discreet. The gentle elasticity usually means that they are also considerably comfier when you’re wearing them on your wrist rather than on your hair- as opposed to usual hairbands you could quickly fail to remember you had just one of these on your wrist. As they are flat and tender, they will certainly minimise kinks, though i really do not see that they’ll remove them wholly. Even so they are unquestionably potent adequate to act like a usual headband- they don’t slide out, and they do not absence stretch. If you’re a common user of headbands, i would undoubtedly say ‘treat yourself’ and advocate a set of these, if you consider they’ll go well with your type.I have very thick hair that frequently breaks hair bobbles, but these are no trouble. They stretched marginally which helped, and they do not experience like they are damaging my hair.I have medium length thick curly hair and was a bit dubious that these would keep it all in place. Even so they doi run a good deal way too and they held my hair in place while managing a fifty percent marathon the other working day. The colours are lovely and they also look great on my wrist when they are not in my hair.I have long, solid, curly hair that can be complicated to take care of, therefore i frequently dress in it tied back again. Many hair ties are complicated to clear away and bring about damage to my hair. These hair ties are simple to use, cozy to dress in, straightforward to get rid of and stylish much too.These are good – definitely cute to dress in on your wrist and do not leave a dent in your hair, even right after hours of it becoming up.The item arrived on time and in brilliant pink shiny envelope with a personalised name tag. I’m a sucker for adorable packaging and compact element so genuinely cherished this notion. I have tried using the bands themselves and they do particularly what there meant to do. Over-all genuinely happy with the service and item.But i observed when i went running they. If you want to tie your hair up when it’s damp and have soft curls, these bands are superior. But i observed when i went jogging they failed to fairly give me ample hold and they slipped a little bit. But they are snug to throw on your wrist and wonderful colors.I truly wasn’t confident that they could be any better than my typical elastic hair ties. When i to start with been given these, i actually wasn’t certain that they could be any far better than my typical elastic hair ties, and in point assumed they ended up it’s possible just a little bit gimmicky, particularly considering the fact that they are marketed as becoming wonderful for carrying on your wrist as nicely as in your hair. On the other hand, they have proved me erroneous. They are straightforward to tie your hair up with, and they preserve the hair well in position. Extra importantly, they really feel definitely relaxed, with none of the tightness of the bands i ordinarily use. They are also significantly much easier to get rid of – generally i have to carefully unwind my hair ties so they you should not rip some hair out when i choose them off, but these can very easily just be slid straight out with not a pulled hair to be felt. I like the understated colors of this set, and they seem to be as though they’ll final a superior prolonged time. I have been using the same 1 for about a week, and it has not stretched or absent loose at all. Extremely amazed, and very likely to get some much more in other colors now i’ve uncovered them.5 loops of textured elasticated ribbon with a refined glitter thread woven into the material. They’re fairly classy looking as considerably as hairbands go, and would perform with a business outfit as nicely as for each day and sports use. They operate like a noose, and are considerably gentler on the hair than the normal elastic loop. I am not absolutely sure they’d be robust plenty of for the ‘croydon facelift’ glance, but great for a wise ponytail.They are simple to use, just loop in excess of and pop in excess of your ponytail. The only downside i can see is that the gap they make when doubled is relatively little. So i imagine these would not be as good on thick hair.Pretty excellent no-tangle ponytail holders. These ponytail holders appear in good neutral colors, have fantastic elasticity and, very best of all, my associate claimed they do not get tangled in her hair, so, over-all, incredibly pleased with these.So numerous + details but toughness a core difficulty. I was so thrilled to see these in the vine programme possessing seen them advert nauseam on every single youtube natural beauty blogger. I opted for the ink assortment which is basically a blend of greys and blacks which make them suitable for function. These are in essence a strip of elastic tied into a loop they have the tiniest amount of money of shimmer in them but you would want to be up shut to see that. The pros:-very at ease to put on-acceptable for the office-substantially cuts down the kink in wet hair-a lot less limited than standard hair ties-does not pull hair when remaining eradicated-fewer hair trapped in the band when removedthe negatives-longevity is an situation-extend out and develop into way too saggy just after a few days regular use-the tapered close gets frayed fairly speedily building them untidy for function use-they never eliminate the kink in soaked hair-price pointoverall these are a wonderful thought and i like the item but for the price tag place, the concerns with toughness is a actual set back again for me and the cause why i individually would not acquire them following these are worn out. The to start with several days have been seriously excellent but then i found that the bands stretched and the tapered ends are not treated so they frayed. You do get 5 in a pack which is great but i am heading via these rather promptly. For the price tag place i would require to see greater longevity and use out of them. You could probably make them previous for a longer time if you did not wear them everyday like i have but i just can’t make mine past. I never make them also limited and once my hair is up for the working day it stays up i’m not one particular to continue to keep having it down and redoing it.Less problems than typical hair bands (even snag free) but just not pretty great ample. First and foremost these are remarkable to your standard elasticated hair bands and even snag-free of charge elasticated bands as they are normally threads woven close to an inner tube of elastic which more than time can capture hairs and rip them out if entangled specifically if with a metallic be part of. This is like the hair tie equivalent of spandex, the fabric is woven with elasticated fibres providing the whole matter extend and almost nothing to snag on. As an individual with really quite thick hair primarily in the ‘kitchen’ or lower again of the head i’m endlessly shedding strands here and there enravelled in standard hair bands, i’ve not lost one hair just after prolonged even sleeping use of these. That would be five stars for me but, there are additional flaws that deliver the rating down for me. The ties on their own are a very little unfastened in the knots and you have to thrust the knots limited normally your pony will slip as you will not be in a position to wrap it close to ample moments to get a tight keep. Even with the knot tightened i was still a little bit sad with the tautness, and had to redo my ponytail a couple occasions thanks to slippage, i would not depend on these holding my thick hair up for an extended time wherever it has to appear best but they are fantastic for an common/casual surroundings. Also the small knot can get bothersome, i know it’s a ‘thing’ now to have decorative bits back again on your hair ties (bobbles, bunny ears, cloth to appear like a right scarf tie and many others) but listed here it really is just a nothing at all of almost nothing and a bit irritating when you run your hand back by means of your hair. I can also see these owning a shorter lifetime-use as becoming like spandex, spandex will give over time and strain that means you can expect to rapidly stop up with saggy hair ands exacerbating the wrapping and support difficulties. As for the ‘kink factor’ it truly is divided, on my tremendous thick hair i had no kink even following sleeping overnight with them but my mum who has significantly thinner hair than mine did have a slight line but maybe which is since she was equipped to get the tie all over her pony tail at minimum after extra than i managed and as a result the strain was increased and concentrated on the hair?total if it wasn’t for the ‘tight enough’ and saggy variable they would have 5 stars, i didn’t have any strain traces but thinner hair does so it depends on your hair texture and what you want from your ponytail.They never cut into my wrist like usual hair ties. They do use out rather swiftly although and they are a lot more costly in comparison to many others but i would endorse them.Cozy and elegant hairbands. This established has a attractive range of inky neutral colours, and this style of hairband is so significantly extra comfortable than typical types, they also never minimize off the blood supply to your wrist if you retain one helpful there.These hairbands are very soft and wide producing them come to feel a lot more at ease in your hair, they have a fantastic good quality come to feel to them. I won’t be able to say i would want to put on them on my wrist any more than many others as the finishes stick out, it in all probability appears a lot more noticeable than your ordinary band but on the in addition aspect they really don’t dig in. They hold my hair up nicely and. They hold my hair up properly and glimpse really lovable. The selection of colours signifies i can match them to my outfits. They also can be worn on the wrist devoid of leaving that hairband indent. I seriously like them and will be getting much more.Nice concept for developed-up hair ties but they soon stretch out of form. These are a great plan: grown-up hair ties that look wonderful and will not pull your hair. The ‘ink’ colour plan of black and greys is also discreet and adult. The trouble, even though, is that whilst these are excellent at 1st, they quickly overstretch and lose their elasticity. That may be fantastic if you only use them often as i do for yoga etc. But if you want them for day to day or frequent use then they have to have to be replaced often.Hairbands for developed upslarge width that is tender stretchy & sort to hair, its challenging to get this tangled in your hair. I like the several shades of grey & black – perfect for perform. I gave some to a pal whose daughter has afro hair & she stated these were the best she had attempted, gentle, light & no tangle.I really wasn’t convinced that they could be any better than my usual elastic hair tiesA bit posh, but worth itGreat Product & Service!Nice idea for grown-up hair ties but they soon stretch out of shapeHairbands for grown upsComfortable and stylishlast_img read more


J&K’s Chenani-Nashri Tunnel renamed after Shyama Prasad Mukherjee


first_imgUnion Minister Jitendra Singh on Thursday said days are not far off when it will be possible to unfurl the tricolour in Pakistan Occupied Kashmir (PoK). “I have faith that under the leadership of Prime Minister Narendra Modi, the way New India’s caravan is progressing ahead, that day is not far off when it will be possible to unfurl that tricolour or ‘Nishan’ for which Shyama Prasad Mukherj sacrificed his life in Pakistan occupied Kashmir,” Mr. Singh said at an event to rename Chenani-Nashri Tunnel in Jammu & Kashmir.Mr. Singh, credited Road Transport and Highways Minister Nitin Gadkari for accepting the proposal of renaming the tunnel after Shyama Prasad Mukherjee without wasting time. In 2017, Prime Minister Narendra Modi had dedicated to the nation this 9 km-long tunnel that reduces the distance between Jammu and Srinagar by 31 km but due to “some compulsions” this could not be named after Shyama Prasad Mukherjee, he said. He further noted that 66 years ago on May 11, 1953, Mukherjee was arrested from Lakhanpur in an illegal manner without any FIR, chargesheet or warning and was taken to Srinagar through this Chenani-Nashri road. After Mukherjee’s death on June 23, 1953 his mother wrote to then Prime Minister Jawaharlal Nehru to hold an enquiry into his death. “For some reasons then Prime Minister Nehru did not pay heed to that letter, no enquiry was done. It is a new era now. It was Nehru government then, today it is Modi government… That probe or lapse can not be compensated but this tribute for coming generation will preserve his heritage and memory. “The lapse on part of Nehru government has been atoned by Modi government,” he said. The decision to rename the tunnel comes over two months after abrogation of the provisions of Article 370. The ‘Chenani-Nashri Tunnel’ was built at the cost of ₹2,600 crore. The tunnel, bypassing snow-bound upper reaches, reduces the journey time by two hours and provide a safe, all-weather route to commuters travelling from Jammu and Udhampur to Ramban, Banihal and Srinagar. The key features of the tunnel are — it is a single-tube bi-directional tunnel, with a 9.35-metre carriageway, and a vertical clearance of 5 metres. There is also a parallel escape tunnel, with ‘Cross Passages’ connecting to the main tunnel at intervals of 300 metres. It also has smart features such as an integrated traffic control system; surveillance, ventilation and broadcast systems; fire fighting system; and SOS call-boxes at every 150 metres.last_img read more
