, Lecture Objectives
• Enumerate different nuclei of basal ganglia
• Know different neurotransmitters that have a role
in basal ganglia functions
• Appreciate general functions of basal ganglia
• Physiological basis of basal ganglia disorders
, BASAL GANGLIA:
NUCLEI
Five nuclei :
Caudate Nucleus
Putamen
Globus Pallidus – external & internal
segments.
Subthalamic Nucleus
Substantia Nigra- pars compacta,reticulata
Basal ganglia: A group of nuclei, act as a unified functional unit.
Basal ganglia: A subcortical nuclei of grey matter located in the interior part of
cerebrum / base of the forebrain
connected with cerebral cortex, thalamus, and other brain areas.
Play a role in action selection, decision of possible behaviors to execute at a given time
