  • The research team, led by Seth Grant of the Sanger Institute near Cambridge, England, compiled the first exact inventory of all the protein components of the synaptic information-processing machinery. No fewer than 1,461 proteins are involved in this biological machinery, they report in the current issue of Nature Neuroscience.
  • Each neuron in the human brain makes an average 1,000 or so connections with other neurons. There are 100 billion neurons, so the brain probably contains 100 trillion synapses, its most critical working part.
  • The 1,461 genes that specify these synaptic proteins constitute more than 7 percent of the human genome’s 20,000 protein-coding genes, an indication of the synapse’s complexity and importance.
  • ...2 more annotations...
  • Dr. Grant believes that the proteins are probably linked together to form several biological machines that process the information and change the physical properties of the neuron as a way of laying down a memory.
  • The new catalog of synaptic proteins “should open a major new window in mental disease,” said Jeffrey Noebels, an expert on the genetics of epilepsy at the Baylor College of Medicine. “We can go in there and systematically look for disease pathways and therefore druggable targets.”

  • Today, Posit Science announced the release of a new computer-based visual training tool, DriveSharp, specifically designed to improve the performance abilities of adult automobile drivers to a degree that can be expected to very substantially impact their driving safety.
  • Again, with a few hours of intensive training, a youthful MOT performance level can be achieved for most individuals. The result: A still FURTHER increase of driving safety.
  • In our fast-moving world, losing control of one’s peripheral vision is a main cause of driving accidents.
  • ...11 more annotations...
  • Ball and Roenker demonstrated that these losses are substantially reversible, through appropriate, intensive training, in almost all older drivers. UFOVs can be re-expanded to relatively youthful ability levels through only a few hours of exercise. The result: About 50% fewer driving accidents in the over-65 population.
  • Moreover, once your UFOV is opened up again, you use it!
  • You can use DriveSharp repeatedly, over the rest of your days, to keep yourself in fine driving fettle!
  • The second training program that is included in DriveSharp is designed to improve your ability to keep track of more than one thing happening at the same time. This fundamental visual skill — called “multiple object tracking” (MOT) — also dramatically declines as you get older.
  • As you get older, you progressively lose the ability to accurately detect and respond to visual events in your far visual periphery.
  • If you’ve reached your 50th birthday, DriveSharp training is especially important for upgrading and sustaining your driving competence. It’s all about maintaining your performance abilities in driving as in all other ways at the highest possible level, throughout the second half of life.
  • few other benefits demonstrated by published studies originating with the Ball/Roenker team (including University of South Florida scientist Sherri Willis and a University of Iowa scientist, Fred Wolinsky).
  • 1) You’re healthier after DriveSharp training! Five years after training, Physical indices of Quality of Life are more than 30% higher — maybe because you get out more.
  • Trainees are much more likely to have retained your driver’s license — and to have sustained their personal independence.
  • After DriveSharp, you are a more confident driver, as expressed by gains in the number of times you drive each week, by an increase in average driving distances, and by your driving more often at night, or in the rain or snow.
  • Try DriveSharp now: If you are a member of one of the participating AAA clubs, please visit your AAA club’s website for more information and a special offer on DriveSharp. If not, please visit www.DriveSharp.com or call (866)599-6463 to learn more.

shared by Tero Toivanen on 21 Jun 09 - Cached
  • A new study by researchers at the Montreal Neurological Institute and Hospital (The Neuro), McGill University and University of California, Los Angeles has captured an image for the first time of a mechanism, specifically protein translation, which underlies long-term memory formation. The finding provides the first visual evidence that when a new memory is formed new proteins are made locally at the synapse - the connection between nerve cells - increasing the strength of the synaptic connection and reinforcing the memory. The study published in Science, is important for understanding how memory traces are created and the ability to monitor it in real time will allow a detailed understanding of how memories are formed.
  • research has focused on synapses which are the main site of exchange and storage in the brain.
  • They form a vast but also constantly fluctuating network of connections whose ability to change and adapt, called synaptic plasticity, may be the fundamental basis of learning and memory.
  • ...3 more annotations...
  • Using a translational reporter, a fluorescent protein that can be easily detected and tracked, we directly visualized the increased local translation, or protein synthesis, during memory formation.
  • Importantly, this translation was synapse-specific and it required activation of the post-synaptic cell, showing that this step required cooperation between the pre and post-synaptic compartments, the parts of the two neurons that meet at the synapse.
  • This study provides evidence that a mechanism that mediates this gene expression during neuronal plasticity involves regulated translation of localized mRNA at stimulated synapses.

Artificial Synesthesia for Synthetic Vision via Sensory Substitution - 0 views

shared by Ruth Howard on 18 Aug 10 - Cached
  • The additional perception is regarded by the trained synesthete as real, often outside the body, instead of imagined in the mind's eye. Its reality and vividness are what makes artificial synesthesia so interesting in its violation of conventional perception. Synesthesia in general is also fascinating because logically it should have been a product of the human brain, where the evolutionary trend has been for increasing coordination, mutual consistency and perceptual robustness in the processing of different sensory inputs.
  • synesthesia
  • options it may provide for people with sensory disabilities like deafness and blindness, where a neural joining of senses can help in replacing one sense by the other:
  • ...3 more annotations...
  • hear colors, taste shapes, or experience other curious sensory modality crossings, allegedly related to abnormal functioning of the hippocampus, one of the limbic structures in the brain. It has also been suggested that synesthesia constitutes a form of "supernormal integration" involving the posterior parietal cortex. The Russian composer Alexander Scriabin and Russian-born painter Wassily Kandinsky both pioneered artistic links between sight and sound, while they may have been synesthetes themselves. Russian mnemonist Solomon Shereshevskii, studied for decades by neuropsychologist Alexander Luria, appears to have used his natural synesthesia to memorize amazing amounts of data.

  • In case of "explicit" synesthesia, the sounds would induce conscious sensations (qualia) of light and visual patterns.

    It's good for your life and health to be optimist.
  • Ruth Howard on 11 Jan 10
     
    It' s a slightly different perspective that I' m enjoying at this time but I appreciate it may only be true for some-I' ve just begun to understand what "faith" means tho I' m not religious-still! (I feel some empathy now as to why people are) I feel much more inclined to just sit still and connect inside with the Source of me-any meditation or spiritual practice can lead me there or creativity,music too,nature! But to deliberately connect to the part of us all that is connected and knows/is All. From that place I' ve understood that theres noone to be, nowhere to go, nothing to do as we are all there already as we are all IT! So of course daily I forget this but this insight has gifted me much more optimism as I can assume that whatever I really ask for/intend/desire is already in the big melting pot that we can Life/God. That is ' faith' Ive realised now- to ask and know intimately that it' s already a given and to STOP Worrying and completely ignore the naysayers etc. It' s really trusting that I' m connected to it all and I am not separate. I' m beginning to observe quite distinctly the thoughts that separate me from what I want/intend. Particularly in relation to my fellow beings! But then I turn to the place that is connected and I feel so good! and just thinking of the situation from that place and holding that good feeling in relation and giving it over (the problem) really helps! I know several spiritual teachers have said "give it over to me". I' m starting to understand it really is that simple. Trying hard and worrying just create such muck and mire! This may be part of the surrender letting go and letting God that others speak of also? I reckon it would be interesting to see where how people get there faith/trust in life that creates the underlying optimism. What gives that to them? I remember as a child I had it naturally I often got what I asked for and intended and there was an abundance of flow and optimism. No resistance. Fear and doubt come later
