| Research Abstract |
I have revealed that somatosensory and visual inputs modulate auditory response of thalamic and thalamic reticular nucleus (TRN) cells in the rat. It is suggested that there exists neural organization for cross-modal sensory interaction (switching of attention) in the loop circuitry between the cortex and thalamus. Further, I have indicated diverse networks of circuit, revealing that the primary and secondary auditory responses have distinct response properties and that visual or auditory response properties are different between TRN cells projecting to the primary (lemniscal) and secondary (non-lemniscal) thalamic nuclei.
