Contribution of Thalamocortical Diaschisis to Attention Disorder in Thalamic Hemorrhage
Kazuhiko Tokoro1*, Hironobu Sato1, Mayumi Yamamoto2, Yoshiko Nagai2, and Masashi Hikita3*
Our brain is constantly exposed to a huge amount of sensory information. Owing to limited processing capacity, sensory input has to be selected and modulated, which is called selective attention. The thalamus receives all sensory signals (with the exception of those from the olfactory system) and sends them to the associated primary cortices. It acts as a sensory gate to filter out unnecessary background information while processing sensory input from the attended stimulus. Although sensory gating is largely automatic (bottom up), it also occurs within the context of attentional processes (top down attention).
