Explain the Nuclei or Ganglia

Deep within the cerebral hemispheres are groups of nerve cells called nuclei or ganglia which act as relay stations, where impulses are passed from one neuron to next in a chain. The basal nuclei are, therefore, also called the basal ganglia. The term "basal" refers to the location of these collections of neurons (nuclei or ganglia) deep within the brain, seemingly at its very base. This region located at the base of the brain is composed of 4 clusters of neurons or nerve cells - sensory nuclei, association nuclei, non specific nuclei and motor nuclei. This area of the brain is responsible for body movements and coordination. The area influences skeletal muscle tone. If control is inadequate or absent, movements are jerky, clumsy and uncoordinated.
