Highlights ► Thalamic reticular nucleus cell activities vary along with targets of projection. ► Cells projecting to dorsal lateral geniculate nucleus show intense burst spiking. ► Cells projecting to lateral posterior nucleus show relatively weak burst spiking. ► Distinctions in burst spiking are found in visual response and spontaneous activity. ► Distinctions are related to topographies of cell body and terminal field locations.
