While functional connectivity networks are often extracted from resting-state fMRI scans, they have been shown to be active during task performance as well. However, the effect of an in-scanner task on functional connectivity networks is no...
Effect of Stimulus Contrast and Visual Attention on Spike-Gamma Phase Relationship in Macaque Primary Visual Cortex [0.03%]
刺激对比度和视觉注意对猕猴初级视皮层神经元 spikes-gamma 振荡相位关系的影响
