Though the research is isolated to the visual cortex
, it suggests that other areas of the brain may also be much more plastic for much longer than previously thought, Murphy said.
Neural response measurements during this task revealed the rapid emergence of value-related signals in the visual cortex
CorticalSight will apply techniques from the field of optogenetics to enable communication between neurons in the visual cortex
and a camera-based, high-definition artificial retina worn over the eyes.
Using our technique, you may visualize the specific information represented by any brain location, and screen through all the locations in the brain's visual cortex
By bypassing the retina and optic nerve and directly stimulating the visual cortex
, a cortical prosthesis system has the potential to restore useful vision to patients completely blinded due to many reasons, including glaucoma, diabetic retinopathy, or forms of cancer and trauma.
Stroboscopic or strobe light was used to elicit the potential for the first clinical VEPs but work by Regan et al showed that the visual cortex
responds better to more structured stimuli with edges rather than diffuse stimuli and paved the way for the use of patterned stimuli.
The human visual cortex
is immature at birth, and acquires deep perception at approximately 6 months after birth, with complete maturation in late childhood.
As a mammal sees more of the world, for example, neurons in the visual cortex
form more connections to the motor cortices, so that the bucket brigade moves faster and more efficiently.
These results indicate that perceived brightness may be encoded in the early visual cortex
The games, which typically involve gunning down bandits or enemy soldiers before they can shoot first, appear to "rewire" parts of the brain's visual cortex
Using two normal-sighted rhesus monkeys, researchers triggered a large area of their brain known as the primary visual cortex
after inserting the micro-electrodes.
These findings indicate a significant enhancement of astrocytic activities in the visual cortex
during aging process.
