The basal ganglia: from motor commands to the control of vigor

The midbrain dopamine system is widely studied for its involvement in emotional and motivational behavior. Some of these neurons receive information from the amygdala and project throughout the cortex. When the circuit and transmission of dopamine is disrupted symptoms may present. Here is the latest research on the amygdala and midbrain dopamine.

The basal ganglia is comprised of the neostriatum, the external and internal pallidal segments, the subthalamic nucleus, the substantia nigra pars reticulata, and the pars compacta of the substantia nigra. The basal ganglia circuitry is responsible for the correct execution of voluntary movements and is implicated in Parkinson's disease. Here is the latest research investigating the basal ganglia in Parkinson's disease.

Here is the latest research on barrel cortex, a region of somatosensory and motor corticies in the brain, which are used by animals that rely on whiskers for world exploration.

Basal Ganglia are a group of subcortical nuclei in the brain associated with control of voluntary motor movements, procedural and habit learning, emotion, and cognition. Here is the latest research.
