Neuroscience Method Of Optogenetics As Good As Electrical Stimulation
2013-12-12 17:27:06

Neuroscientists are eagerly, but not always successfully, looking for proof that optogenetics – a celebrated technique that uses pulses of visible light to genetically alter brain cells to be excited or silenced – can be as successful in complex and large brains as it has been in rodent models.

Challenging The Brain's Visual System In New Environments

When people escape from the grind of their day-to-day lives and travel to remote, tranquil places, they often claim to “turn off” their brains so that they can soak in the calm, relaxing environment. However, your brain is working just as hard as ever.

The human eye long ago solved a problem common to both digital and film cameras: how to get good contrast in an image while also capturing faint detail.

The properties of optical stimuli need to be conveyed from the eye to the brain.

Physicists and neuroscientists from the University of Pennsylvania have linked the cell structure of the retina to the light and dark contrasts of the natural world, demonstrating the likelihood that the neural pathways humans use for seeing are adapted to best capture the world around us.

The visual system has limited capacity and cannot process everything that falls onto the retina. Instead, the brain relies on attention to bring salient details into focus and filter out background clutter.

Researchers at Harvard University have found evidence that the retina actively seeks novel features in the visual environment, dynamically adjusting its processing in order to seek the unusual while ignoring the commonplace.


Word of the Day
obdormition
  • Sleep; the state or condition of being asleep.
  • The state or condition of numbness of a part due to pressure on a nerve: as, the obdormition of a limb.
The word 'obdormition' comes from a Latin word meaning "to fall asleep".
