The main difference is their mode of afference.

The striatal afference contribute for more than 90% of synapses.

The main afference of the pars media is the medial pallidum.

The subthalamic nucleus receives its main afference from the lateral pallidum.

One subcortical afference comes from the perithalamus (reticulate nucleus).

The anterior region receives a particular afference that is not entirely subcortical (directly or indirectly from the subiculum).

Capsaicin sensitive afference neurones have previously been reported to play a prt in gastric mucosal protection.

In addition to the striato-pallidal afference, the lateral pallidum receives a major connection from the subthalamic nucleus (see below).

This shows that when the efference copy is incompatible with the afference, the sensory information is perceived as if it were exafference.

Sensory information coming from sensory receptors in the peripheral nervous system to the central nervous system is called afference.

Another afference comes from the cerebral cortex (glutamatergic), particularly from the motor cortex, which is too much neglected in models.

The sensory function of the trigeminal nerve is to provide the tactile, proprioceptive, and nociceptive afference of the face and mouth.

Thus, while motor efference commands to the facial muscles remain intact, sensory afference from extrafusal muscle fibers, and possibly intrafusal muscle fibers, is diminished.

In addition to the nigral afference, VA receives axons from the tectum (superior colliculus) and from the amygdala (basal complex), which makes a singular set of afferences.

If one adds all those reaching this target, the main afference of the subthalamic nucleus is, in 82.7% of the cases, the lateral pallidum (external segment of the globus pallidus.

Corollary discharge is characterized as an afference copy of an action command used to inhibit any response to the self generated sensory signal which would interfere with the execution of the motor task.
