Mid -sagittal Section Pituitary Gland

The Autonomic Nervous System

Hypothalamic Control of Pituitary Hormones ACTH, gonadotropic h. Oxytocin, Vasopressin

The Limbic System and Hypothalamus

Limbic System (Papez-MacLean): Emotions related to survival and reproduction Amygdala: Kluver-Bucy syndrome- fearless, docile, hpersexualuality, hyperorality Septum: aggression, sex (Heath), DA Cingulate cortex: oxytocin (attachment, social, family-related emotions), subjective feelings, emotional component of pain, awareness of environment Hippocampus: cognitions, H.M. encoding of declarative (episodic, semantic) memories

The Cerebral Cortex areas Central Fissure Lateral Fissure

Topographic organization of motor and somatosensory areas Hip Knee Leg Foot Toes Gentials

Left-hemisphere Language Areas Broca’s area Motor area Primary auditory area (buried in fissure) Parietal - temporal junction area Somatosensory

1. Body sense ( self- awareness ) 2. Split- brain-- left conscious; if language in both, both hemispheres conscious 3. “Interpreter” ( Gazzaniga ) PREFRONTAL CORTEX Working memory – “executive” functions Mirror-Neurons -- TOM PARIETAL- TEMPORAL JUNCTION
