HIPPOCAMPUS
Cytoarchitecture: CA1: parvocellular: Limit HIPC - subiculum, CA2: Mixed; CA3: magnocellular (CA2 + CA3 = within HIPOCAS); CA4: Limit HIPC - c. dentate
Afferent: 1) entorhinal cortex-v.perforante-> dentate molecular layer -> CA3 -> CA1 -> subiculum 2) amygdaloid complex -> subiculum 3) Formix
Efenetes: 1) subiculum -> Alveo -> Fimbria -> Fornix -> (1) -> postcomisural (subiculum) => [n. medial mamillary, n. VM Hipot, n. ants T] 2) precomisural (HIPOCAS) => [n. septal, a. medial cortex F, n. preoptic, N. Hipot ants, n. accumbens]) 2)Pyramid HIPOCAS -> Alveo ->......
Full Papez circuit: subiculum-> n. mamillary-f. mamillothalamic-> n. Tf ants. Thalamocortical-> cingulate cortex cir-> Cingular -> 1) -> entorhinal cortex 2) subiculum
Intrinsic circuit HIPC: C. entorhinal -> layer Molec CA4, CA3 -> fimbria. molecular layer-> CA2, CA1 -> Fimbria. CA2, CA1 -> molecular layer of subiculum -> (1) fimbria; 2) c. entorhinal)

LCF
Produced by choroid plexus, passive movement (May q weight blood), absorption at arachnoid villi. (foramen of Monro + aqueduct)
--------------------------------
Visual Pathways: Light-> cones + rods-> c bipolar-> c.ganglionares-> n.optico-> chiasm-> tract opt-> GL ([eye against: 1,4,6] [eye ipsi: 2, 3,5] -> radiation optical-> 2-beam [1) contralateral hemifield f. quadrant inf-> GL (dm) -> capsula int-> lip sup calcarine sulcus (A17)] [2) f.cuadrante sup-> GL (vm) -> T-Lob white sust> Jonathan Meyer-> inf lip groove calcarine (A17)] A17-> A18-> bark pref
----------------------------------
Taste: 1 / 3 -> (X + IX) / 2 / 3 (VII) => n. lat solitary tract -> 1) VPM -> gustatory cortex (parietal operculum) 2) N. parabrachial -> amygdala

Auditory Pathways: Coclea-> n. Cochlear -> 1) against: lemniscus lat <-> colliculus inf-> FM-> (A1 to A1 + A2 IV I II) 2) bi: C. coliva sup -> trapezoid body -> lat lemniscus. C.olivar sup -> c hair ext.
------------------------
Smell: Olfactory bulb glomeruli with (+ mitral tufted cell) -> (cortex, piriform, entorhinal cortex, amygdala, tuberculosis inf) -> Bark F -> orbitofrontal cortex (add to taste)
------------------------------
VIAS somesthetic
Via epicritic: G. cord -> ME -> CP -> medial lemniscus -> VPL
Via protopathic termoalgesia touch and G. cord -> ME -> SAL -> Po, VPL, intralaminar
Via epicritic trigeminal G. Gasset -> N. trigeminal Ser -> trigeminal lemniscus -> VPM
Via protopathic trigeminal G. Gasset -> N. spinal trigeminal -> Po, VPM, intralaminar
Via paleo-spino-thalamic: multisynaptic -> N. spinal trigeminal -> Po intralaminar, MPV
------------------------------
Induction, neurulation, proliferation, differentiation, migration, cell aggregation selctiva, neuronal maturation, selective neuronal death and selective axon elimination.
