Basal ganglia are a group of subcortical nuclei, of varied origin, in the brains of vertebrates. These are located at the base of the forebrain and top of the midbrain. The cerebral cortex, thalamus, and brainstem, as well as numerous other brain areas are all closely linked to the basal ganglia. Various functions are related with basal ganglia, such as the control of voluntary motor movements, procedural learning, habit learning, conditional learning, eye movements, cognition and emotion. The basal ganglia play a critical role in brain function and behavior. Their dysfunction causes a wide range of neurological conditions including disorders of behavior control and movement, as well as cognitive deficits which are similar to those caused by prefrontal cortex injury. This book includes some of the vital pieces of work being conducted across the world, on basal ganglia and related motor and cognitive functions. It will provide comprehensive knowledge to the readers.

The collection of subcortical nuclei which handle motor control, motor learning, executive behaviors and functions, and emotions is known as the basal ganglia. It is situated at the base of the forebrain and above the midbrain. The striatum, which includes the dorsal striatum and ventral striatum, the globus pallidus, the ventral pallidum, the substantia nigra, and the subthalamic nucleus are its principal functional components. Each of these components has a complicated internal anatomical and neurochemical organization. The striatum gets input from various brain areas beyond the basal ganglia but only provides output to other components of the basal ganglia. The globus pallidus receives input from the striatum and gives inhibitory output to variety motor-related areas. This book explores all the important aspects of the basal ganglia. It elucidates the concepts and innovative models around prospective developments with respect to the latest studies on this topic. This book will prove to be immensely beneficial to students and researchers in this field.
