Decoding and reconstructing color from responses in human visual cortex.

2 Nov 2009 How is color represented by spatially distributed patterns of activity in visual cortex? Functional magnetic resonance imaging responses to several stimulus colors were analyzed with multivariate techniques: conventional pattern classification, a ... Read more...

Stimulus-induced and state-dependent sustained gamma activity is tightly coupled to the hemodynamic response in humans.

2 Nov 2009 A prompt behavioral response to a stimulus depends both on the salience of the stimulus as well as the subject's preparedness. Thus, both stimulus properties and cognitive factors, such as attention, may determine the strength of neuronal ... Read more...

Selective targeting of the dendrites of corticothalamic cells by thalamic afferents in area 17 of the cat.

2 Nov 2009 Pyramidal cells of layer 6 in cat visual cortex are the source of the corticothalamic projection, and their recurrent collaterals provide substantially more excitatory synapses in layer 4 than does the thalamic input. They have predominantly simple ... Read more...
