representation of neural activity fluctuations in the human visual cortex

A computer model can predict rapid fluctuations in neural activity in the human visual cortex.

An international team of neuroscientists used medical data to record human neural activity of visual processing in exceptional detail.

The researchers examined volunteer epilepsy patients who had been implanted with electrodes in order to measure seizure-associated neural activity. Recordings made as patients watched pictures on a laptop showed computational models that were designed to explain neural responses in non-human primates are applicable to human brains. The results indicate that the models can accurately predict changes in human neural activity for various changes in a visually presented image, according to the team's published report.

"We found that both human and animal brains seem to be using a similar 'toolkit' of neural calculations to make sense of the continuous stream of inputs arriving from our senses," says Iris Groen, an assistant professor at the University of Amsterdam, the Netherlands.
