Labeled anatomical diagram of the limbic system showing: cingulate gyrus, hippocampus, amygdala, hypothalamus, mammillary body, fornix, parahippocampal gyrus, thalamus (anterior nucleus), septum, olfactory bulb. Show Papez circuit connections with arrows. Clean medical textbook style, white background.

Medical diagram showing three functional divisions of the cerebellum: Archicerebellum (vestibulocerebellum - flocculonodular lobe), Paleocerebellum (spinocerebellum - vermis and intermediate zone), Neocerebellum (cerebrocerebellum - lateral hemispheres). Show afferent connections (spinocerebellar tracts, vestibular, corticopontine) and efferent connections (dentate, emboliform, globose, fastigial nuclei to thalamus, red nucleus, vestibular nuclei). Textbook style with clear labels.

Labeled diagram of basal ganglia connections showing: caudate nucleus, putamen (together = striatum), globus pallidus (internal and external), subthalamic nucleus, substantia nigra (pars compacta and pars reticulata). Show direct pathway (excitatory - Striatum to GPi) and indirect pathway (inhibitory), dopaminergic nigrostriatal pathway. Indicate what is lost in Parkinson's disease. Clean medical diagram on white background.

Detailed labeled diagram of a chemical synapse showing: presynaptic terminal (with mitochondria, synaptic vesicles containing neurotransmitters), synaptic cleft, postsynaptic membrane (with receptor channels), voltage-gated calcium channels, neurotransmitter release, EPSP and IPSP. Show ionic basis: Na+ influx for EPSP, Cl- influx for IPSP. Clear medical textbook diagram with labels.
