Neuroscientists want to understand how individual neurons encode information that allows us to distinguish objects, like telling a leaf apart from a rock. But they have struggled to build ...

New research reveals that the brain may be learning even during unstructured, aimless exploration. By recording activity in ...

Deep learning models, such as convolutional neural networks (CNNs) and recurrent neural networks (RNNs) are designed to ...

Neurons in visual cortex of the brain ‘drift’ over time Date: August 27, 2021 Source: Washington University in St. Louis Summary: New research reveals that neurons in the visual cortex -- the ...

Secondary visual cortex. The secondary visual cortex is also designated V2, V3, V4, V5, or Brodmann areas 18 and 19. It surrounds the primary visual cortex and receives information from it.

Thus, only the visual cortex is vulnerable in a way that warrants internally-generated activity to preserve its territory. In humans, sleep is punctuated by rapid eye movement (REM) sleep every 90 ...

During this task, researchers recorded neural activity in the monkey’s primary visual cortex, the brain’s main gateway for visual information processing. The researchers found that the specific ...

It conforms to when the visual cortex needs to start defending its territory, Eagleman argues. Scans of dreaming people show most of the brain activity associated with REM is within the visual cortex.

The research to date has used just one UEA, but in the future, Fernández would like to implant several UEAs into the visual cortex to produce a more complicated form of artificial vision. Earlier ...

In the scans, the patient’s visual cortex was significantly lit up only when he saw the photos. In a 2010 case study, Zeman described him as having “blind imagination. ...
