Neurons lose information at one bit per second

February 14, 2011

It appears that information is lost in the brain as quickly as it can be "delivered" from the senses.

This has fundamental consequences for our understanding of the neural code of the cerebral cortex. Due to the high deletion rate, information about sensory input signals can only be maintained for a few spikes. These new findings therefore indicate that the dynamics of the cerebral cortex are specifically tailored to the processing of brief snapshots of the outside world.
