## Resource

Video: https://www.youtube.com/watch?v=hTW8CSPVEGc In this whiteboard episode, we revisit the basal ganglia's intricate circuitry, detailing its five subcortical nuclei—dorsal striatum (caudate/putamen inputs), globus pallidus externa/subthalamic relays, and globus pallidus interna/substantia nigra reticulata outputs—driving the classic direct (facilitatory "go") and indirect (suppressive "no-go") pathways for action selection and inhibition. Excitatory cortical inputs converge on medium spiny neurons, finely tuned by dopamine (D1 excitatory/D2 inhibitory via substantia nigra pars compacta), serotonin, and acetylcholine, to orchestrate habits, motivation, and movement suppression through thalamic modulation. In autism, morphological alterations in medium spiny neurons—enlarged dendritic spines and reduced synaptic flexibility—bias toward repetitive behaviors, ritualized patterns, and intensely fixated interests (DSM-5 B2/B3 criteria), underscoring the circuit's preference for sameness via strengthened plasticity and limited prefrontal override.
