Processing of spatial and object information is segregated into two cortical visual pathways, but it is unclear where this information is unified. This study showed that in monkeys performing tasks that involve saccadic eye movements, neurons in the tail of the caudate nucleus (CDt) encode both object-specific and position-specific information of visual objects. In addition, weak electrical stimulation in the CDt induced saccades, and CDt neurons became active before saccades to particular positions and particular objects. These findings suggest that CDt neurons guide saccades to particular visual objects in particular locations.
