Beyond a relay nucleus: neuroimaging views on the human LGN

WebThe electrical signals then travel to the lateral geniculate nucleus (LGN) of the thalamus, which acts as a relay station for the signals. From the LGN, the signals are sent to the primary visual cortex (V1) in the occipital lobe. This is the main processing area for visual information in the brain. WebThe lateral geniculate nucleus (LGN) is the thalamic station in the retinocortical projection and has traditionally been viewed as the gateway for sensory information to enter the cortex. Here, we review recent studies of the human LGN that have investigated the retinotopic organization, physiologic response properties, and modulation of neural ...
