3 NEURAL COMMUNICATION (I) (Action potential propagation)

4 NEURAL COMMUNICATION (II) (Synaptic Transmission)

5 DIVISIONS OF THE BRAIN ForebrainMidbrainHindbrain Cerebrum Thalamus Hypothalamus Cerebral peduncle Tectum Brainstem Cerebellum Pons Medulla Oblongata Sagittal View of the Brain

6 FUNCTIONAL REGIONS OF THE BRAIN The CerebrumThe CerebellumThe Brain Stem

7 ANATOMY OF THE CEREBRUM Cerebral Hemispheres (View from Above) LeftRight

8 FUNCTIONS OF THE CEREBRUM Frontal lobe: Voluntary movement Higher intellectual functions Temporal lobe: Speech & Sound Complex visual perceptions Occipital lobe: Vision Parietal lobe: Sensory processes Attention Language

9 CONTRALATERAL FUNCTION OF THE CEREBRUM

10 ANATOMY OF THE CEREBELLUM 1. Left Cerebellar Hemisphere 2. Right Cerebellar Hemisphere 3. Vermis 21 3 Spinal cord

11 CEREBELLAR FUNCTIONS

12 ANATOMY OF THE BRAINSTEM

13 FUNCTION OF THE BRAINSTEM Midbrain: Visual & auditory processing and reflexes Fine-tuning of voluntary movements Pons: Relay station for cerebellum Control of sub-conscious movement Medulla Oblongata: Control of cardiovascular functions Control of respiration Control of gastrointestinal functions

14 RETICULAR FORMATION Functions: Regulation of autonomic functions, alertness and sleep

15 THE LIMBIC SYSTEM

16 FUNCTIONS OF THE LIMBIC SYSTEM Cingulate cortex: Coordination of sensory signals Emotion Hippocampus: Long-term memory development Hypothalamus: Endocrine regulation Body temperature Regulation of thirst and hunger Regulation of circadian rhythms Amygdala: Aggression and fear Septal area: Sexual arousal
