Description
Abstract
The thalamostriatal projections are largely
neglected in current reviews dealing with basal ganglia
function. In the past few years, however, several studies
have re-evaluated these projections and have postulated
their implication in more complex tasks within the basal
ganglia organization. In this review, we try to focus on
the morphological and functional importance of this
system in the basal ganglia of the rat, cat and monkey.
Special attention is paid to the thalamus as an important
place for interaction between the input and the output
systems of the basal ganglia through the thalamostriatal
projections. Thus, we stress on the overlapping thalamic
territories between the thalamic projection of the output
nuclei of the basal ganglia and the thalamostriatal
neurons. Our experimental data support the existence of
several thalamic feedback circuits within the basal
ganglia functional design. Finally, some considerations
are provided upon the functional significance of these
thalamic feedback circuits in the overall organization of
the basal ganglia in health and disease.
