WebAug 1, 1996 · It is shown that the information conveyed by an action potential depends on the duration of the immediately preceding interspike interval (ISI), and the evidence suggests that visual neurons are well equipped to decode stimulus-related information on the basis of relative spike timing and ISI duration. 179 PDF WebJun 4, 2024 · We recorded simultaneously from ∼20,000 neurons in mouse primary visual cortex (V1) and found that the neural populations had discrimination thresholds of ∼0.34° …

WebAug 25, 2010 · Although the neural coding precision was high for random tone sequences and natural sounds, the information lost at a precision coarser than a few milliseconds was higher for the stimulus sequence that varied on a faster time scale (random tones), suggesting that the precision of cortical firing depends on the stimulus dynamics.
