The brain is the seat of consciousness. The hypothalamus controls homeostatic mechanisms and is highly vascular. It is connected to the pituitary gland via the infundibulum, which contains both nerves and blood vessels. The hypothalamus contains the satiation center that regulates hunger and monitors food intake. Stimulation of hypothalamic nuclei produces various emotions like fear and pleasure. The limbic system, including the amygdala, hippocampus, hypothalamus, cingulate gyrus, and prefrontal area, is involved in emotional behavior, memory, motivated behaviors, and regulation of aggression.

2.  BRAIN- SEAT OF CONCIOUSNESS.
 HYPOTHALAMUS- HIGHLY VASCULAR.
CONTROLS HOMEOSTATIC MECHANISM.
 PITUTARY GLAND- INFUNDIBULUM CONNECTS
THE HYPOTHALAMUS TO PITUTARY. IT
CONTAINS BOTH NERVES AND BLOOD
VESSELS.

5. Satiation centre/ Hunger
Centre
Regulate hunger
Located in the ventro-median
part of the hypothalamus.
Satiation centre monitors the
quantity of food

6.  STIMULATION OF HYPOTHALAMIC
NUCLEI PRODUCES VARIOUS EMOTIONS
SUCH AS FEAR, PLEASURE etc.
 SOME FUNCTIONS ARE UNDER THE
CONTROL OF AUTONOMIC NERVOUS
SYSTEM THAT ARE INFLUENCED BY
EMOTIONS.

7.  IT IS CONTROLLED BY THE ANTERIOR
PART OF THE HYPOTHALAMUS AND THE
NEIGHBOURING SEPTAL REGION.
 HORMONAL STIMULATION.

8.  CEREBRAL CORTEX – CONTROLS
EMOTIONAL BEHAVIOUR.
 NEOPALLIUM-AROUSAL OF
AGGRESSIVE BEHAVIOUR.
 PALAEOPALLIUM- PLACID
BEHAVIOUR.

10.  IN 1878,THE FRENCH
NEUROLOGISTPAUL BROCA-LIMBIC
LOBE(LIMBIC SYSTEM)
 1)AMYGDALA- IDENTIFICATION OF
DANGER ,SELF PROTECTION,
FEAR,LOVE,FRIENDSHIP etc.
 2)HIPPOCAMPUS- LONG TERM MEMORY
 3)HYPOTHALAMUS-MOTIVATED
BEHAVIOUR,
THERMOREGULATION,SEXUALITY.HUNG
ER,THIRST.

11.  4)CINGULATE GYRUS-EMOTIONAL
REACTION TO PAIN,REGULATION OF
AGGRESSIVE BEHAVIOUR
 5)PRE-FRONTAL AREA- IT COMPRISES
THE ENTIRE NON-MOTOR ANTERIOR
REGION OF FRONTAL LOBE. THE
MANIFESTATION AND REGULATION OF
SEVERAL BEHAVIOUR AND
MOTIVATIONAL DRIVES.
