The primary visual cortex (V1) is probably the best characterized area of primate cortex, but whether this region contributes directly to conscious visual experience is controversial. Early ...

We investigated these issues by recording intracellularly from 95 neurons in primary visual cortex of anesthetized cats. We found that the amplitude of the fluctuations did not change with a stimulus.

Researchers have now shown that, despite individual differences in neuron activity, a shared underlying structure guides the ...
