Welcome to this
Henry Stewart talk devoted
to the anatomical organization
of the basal ganglia.
My name is Andre Parent.
I am professor of
neuroscience at the University
Laval in Quebec City, Canada.
The aim of this presentation
is to provide an overall review
of the basal ganglia organization,
based on that I gathered
from the current literature,
as well as a result
of our own morphological studies
of the basal ganglia undertaken
in humans and non-human primates.
The talk is divided into
four distinct parts.
The first part concerns the overall
organization of the basal ganglia.
A special attention will be paid to
the dual basal ganglia model, which
is widely used to explain the
functional organization of the sets
of subcortical structures
in both health and disease.
The second part summarizes the
result of our own single-axon
tracing studies of the various
basal ganglia components in monkeys.
The third part is devoted to the
presence of dopaminergic neurons
within the primate striatum.
The last part of the
presentation reviews evidence
for the persistence of neurogenesis
in the striatum of adult primates.
