2. INTRODUCTION:
Limbic system is a complex system of cortical and subcortical
structure that form a ring around Hilus of cerebral hemisphere.
It is also known as limbic lobe (limbus– Ring )
Earlier, called as RHINONCEPHALON
6. FUNCTIONS
• 1. Olfacation : piriform cortex and Amygdaiod nucleus
form olfactory centre.
• 2. Regulation of endocrine gland : Hypothalamus regulates
Endocrine secretion
• 3. Regulation of autonomic functions : Hypothalamus
regulates autonomic functions – Heart rate , body
temperature, water balance, blood pressure.
7. CONTINUE
4.Regulation of food intake
5.Control of circadian rhythm : Hypothalamus plays major role in
Circadian fluctuation of various physiological activities.
6. Role in emotional state: Emotional state is maintained by
HIPPOCAMPUS + HYPOTHALAMUS.
7. Role in memory: Hippocampus + papez circuit role in memory.
8. CONTINUE
• Interconnection between various structure of limbic system which form
a complex circuit .
• Role in memory encoding.
