Visual training to retain driving competence - and your independence! | On the Brain by... - 1 views

  • 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.

Naps, Learning and REM : The Frontal Cortex - 0 views

  • Taking a nap without REM sleep also led to slightly better results. But a nap that included REM sleep resulted in nearly a 40 percent improvement over the pre-nap performance.
  • The study, published June 8 in The Proceedings of the National Academy of Sciences, found that those who had REM sleep took longer naps than those who napped without REM, but there was no correlation between total sleep time and improved performance. Only REM sleep helped.
  • Numerous studies have now demonstrated that REM sleep is an essential part of the learning process. Before you can know something, you have to dream about it.

  • The breakthrough came in 1972, when psychologist Jonathan Winson came up with a simple theory: The rabbit brain exhibited the same pattern of activity when it was scared and when it was dreaming because it was dreaming about being scared. The theta rhythm of sleep was just the sound of the mind processing information, sorting through the day's experiences and looking for any new knowledge that might be important for future survival. They were learning while dreaming, solving problems in their sleep.
  • Wilson began his experiment by training rats to run through mazes. While a rat was running through one of these labyrinths, Wilson measured clusters of neurons in the hippocampus with multiple electrodes surgically implanted in its brain. As he'd hypothesized, Wilson found that each maze produced its own pattern of neural firing. To figure out how dreams relate to experience, Wilson recorded input from these same electrodes while the rats were sleeping. The results were astonishing. Of the 45 rat dreams recorded by Wilson, 20 contained an exact replica of the maze they had run earlier that day. The REM sleep was recapitulating experience, allowing the animals to consolidate memory and learn new things. Wilson's lab has since extended these results, demonstrating that "temporally structured replay" occurs in both the hippocampus and visual cortex.

Artificial Synesthesia for Synthetic Vision via Sensory Substitution - 0 views

  • 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:

  • 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 seeing with your ears when using a device that maps images into sounds, or in hearing with your eyes when using a device that maps sounds into images.
  • In case of "explicit" synesthesia, the sounds would induce conscious sensations (qualia) of light and visual patterns.
