چکیده

Our electrodes were typically separated by approximately 1-3 millimeters. However, because the electrodes are flexible and can bend, we are not confident of the separation of individual penetrations, and therefore cannot make a strong statement about how correlations varied as a function of distance. We can, however, separately analyze pairs recorded on the same electrodes versus different electrodes. This analysis is shown in Supplemental Figure 1.

Spatial Attention Decorrelates Intrinsic Activity Fluctuations in Macaque Area V4

Attention typically amplifies neuronal responses evoked by task-relevant stimuli while attenuating responses to task-irrelevant distracters. In this context, visual distracters constitute an external source of noise that is diminished to improve attended signal quality. Activity that is internal to the cortex itself, stimulus-independent ongoing correlated fluctuations in firing, might also act...

Differential temporal storage capacity in the baseline activity of neurons in macaque frontal eye field and area V4.

Previous studies have suggested that spontaneous fluctuations in neuronal activity reflect intrinsic functional brain architecture. Inspired by these findings, we analyzed baseline neuronal activity in the monkey frontal eye field (FEF; a visuomotor area) and area V4 (a visual area) during the fixation period of a cognitive behavioral task in the absence of any task-specific stimuli or behavior...

Short-latency category specific neural responses to human faces in macaque inferotemporal cortex

In this article I would present evidence to show that timing of the flow of neural signals within the ventral visual stream is a crucial part of the neural code for categorization of faces. We recorded the activity of 554 inferotemporal neurons from two macaque monkeys performing a fixation task. More than 1000 object images including human and non-primate animal faces were presented up to 10 t...
