Fig. 11.4 Efferent connections of the striatum.

Globus Pallidus

Afferents

See Fig. 11.5.

There are two major sources of input to the globus pallidus:

Striatum (putamen and striate nucleus) Fibers from the striatum are projected topographically onto the globus pallidus. The pars reticulata of the substantia nigra, which is functionally similar to the globus pal-lidus, also receives topographically organized afferents from the striatum (not shown in this figure).

Subthalamic nucleus The subthalamic nucleus projects topographically organized fibers on the globus pallidus as part of a major side loop.
