Ernst Niebur - Picture Details

 

 

 

Synchrony between neurons correlates with the attentional state. Spike trains were recorded from two neurons simultaneously in somatosensory cortex. Each row in the figure corresponds to one trial, with the time axis horizontal, and each red and each green dot marks the time when an action potential occurred in either one or the other neuron. Blue dots indicate when both neurons fire synchronously (within a few milliseconds). When the animal attends to the stimulus that is being represented by the recorded neurons (left), many more synchronous events (blue dots) occur compared to when the same stimulus is presented but not attended (right)
