Causes Watch this video about: Athetosis resulting from basal ganglia injury Basal ganglia disease is a group of physical problems that occur when the group of nuclei in the brain known as the basal ganglia fail to properly suppress unwanted movements or to properly prime upper motor neuron circuits to initiate motor function. The basal ganglia or basal nuclei is a structure located deep within the brain, and it’s made up of a group of nuclei - so millions of nerve cell bodies. Put simply, the cerebral cortex decides how it wants to move the body and sends that input to the basal ganglia, and then the basal ganglia’s job is to help execute a smooth movement. The basal ganglia are the oldest structure in your brain, one that has been coordinating movement, motivation, and reward for some 560 million years. Read on to find out how it works and what kind of substances can affect it.

The lesions of Basal nuclei occur when they fail to act proper infornation to cerebral cortex to suppress unwanted movements or to initiate motor activity. there are two types of disorders: The basal ganglia consist of a number of subcortical nuclei. The grouping of these nuclei into the basal ganglia is related to function much rather than anatomy: its components are not part of a single anatomical unit and are rather spread deep within the brain. The major anatomical connections of the basal ganglia are reviewed, emphasizing the inputs to the striatum and efferent projections from the major output nuclei, the internal segment of globus pallidus and the pars reticulata of substantia nigra. The results from lesioning experiments, electrical st … The basal ganglia are large subcortical structures comprising several interconnected nuclei in the forebrain, diencephalon, and midbrain.

This structure important in regulating voluntary movements. Unlike the other ganglia mentioned above, it’s not part of the peripheral nervous system. Being in the brain, it’s part of the central nervous system.
