The basal nuclei, also known as basal ganglia, play a pivotal role in modulating movement, cognition, and behavior through intricate neural circuits. This diagram illustrates the connections within the basal nuclei, highlighting key structures such as the cortex, striatum, GPi/SNr, SNc, GPe, STN, and thalamus, along with neurotransmitters including GABA, glutamate, and dopamine. Understanding these pathways provides essential insights into how the brain coordinates voluntary actions and maintains motor control.

Neurotransmitter systems form the backbone of chemical signaling in the nervous system, categorized into cholinergic, amino acid, biogenic amine, and neuropeptide groups, each with unique neurotransmitters, receptors, elimination methods, and postsynaptic effects that influence neuronal communication. This table provides a structured overview of these systems, highlighting how they contribute to functions ranging from muscle control to mood regulation and pain modulation. By exploring these characteristics, one can appreciate the diversity and specificity of synaptic transmission essential for brain function and overall physiology.
