Brain neuronal circuits

Brain neuronal circuits are interconnected assemblies of neurons that form the basic computational and signaling units of the brain, mediating all sensory, motor, cognitive, and emotional processes. Each circuit is composed of excitatory and inhibitory neurons linked by synapses; their molecular composition includes diverse receptors, ion channels, synaptic proteins, and neurotransmitter systems, which collectively determine functional properties. Modern neuroscience targets molecules and cell populations within these circuits, as the circuit itself is not a canonical drug target. Understanding their structure and function is crucial for developing interventions in neurological and psychiatric disorders.
