Using rare brain recordings from patients, scientists found that the thalamus helps trigger visual awareness. The study ...

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.

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 ...
