Subject:
Neuroscience, Behavioral Neuroscience

Since sparse coding on the cellular level was shown to be closely related to glutamate and GABAergic-mediated neural inhibition, one would suspect both to also be central in mediating the sparse ... More

Georg Northoff

in Unlocking the Brain: Volume 1: Coding

Published in print:
2013
