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 Cortexareas

Topographic organization of motor and somatosensory areas

Gentials
Left-hemisphere Language Areas
Broca’s area Motor areaPrimary 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
