Functional magnetic resonance imaging has been successfully used to map the activation in the lateral geniculate nucleus (LGN) in both hemispheres as well as the primary visual cortex (V1) during a checkerboard visual stimulation. The average blood oxygenation level dependent (BOLD) change in LGN wa
## Abstract The anterior chorioidal artery supples the main part of the ventral nucleus and the anterodorsal pole of the dorsal nucleus.
Responses to sudden shifts of a pattern far away from the receptive field (shift-effect) were found in 73 out of 81 cells of the ventral, magnocellular LGN layers, but in only 26 out of 85 cells of the dorsal, parvocellular layers. Most of the former responses were clear and excitatory, and most of
