The information that is sent from the globus pallidus in the caudate circuit can go to both the dorsal and ventral parts of the thalamus.
The globus pallidus is a component of the basal ganglia, a group of nuclei involved in motor control and other functions. The caudate nucleus is another basal ganglia structure that is interconnected with the globus pallidus.
The output from the globus pallidus divides into two pathways known as the direct and indirect pathways. In the direct pathway, signals from the globus pallidus are sent to the ventral anterior and ventral lateral nuclei of the thalamus. These thalamic nuclei then project to the motor cortex, facilitating movement.
In the indirect pathway, signals from the globus pallidus are sent to the subthalamic nucleus and then to the external segment of the globus pallidus. From there, the information is relayed to the ventral anterior and ventral lateral nuclei of the thalamus, which also project to the motor cortex. However, this pathway has an inhibitory effect on movement.
Therefore, information can be sent from the globus pallidus to both the dorsal and ventral parts of the thalamus, depending on whether it is following the direct or indirect pathway.
