1. UNIT 3 THE CONSCIOUS SELF
AREA OF STUDY 1: MIND, BRAIN & BODY

2. THE CENTRAL NERVOUS SYSTEM
KK 5A – PAGE 170

3. THE BRAIN
THE ‘MASTER’ ORGAN responsible for everything that you think, feel and do
Encased in the skull
Weighs around 1.5 kgs
Contains a complex structure of billions of neurons and trillions of connections between these neurons
These connections form pathways throughout the brain that enable transmission of information

4. THE CEREBRAL CORTEX
The convoluted outer layer covering the two cerebral hemispheres
Involved in with information-processing activities such as perception, language, learning, memory, thinking and problem-solving. Also involved with control of voluntary movement
The areas of the cerebral cortex and their main functions can be organised into 3 broad categories:
SENSORY CORTEX AREAS
- process information from senses
MOTOR CORTEX AREAS
- send information about bodily movement
ASSOCIATION CORTEX AREAS
- integrate sensory, motor & other information
- involved in more complex mental activities

6. THE CEREBRAL CORTEX CEREBRAL HEMISPHERES
The cerebral cortex is described as having two halves called ‘cerebral hemispheres’
These are two almost symmetrical brain structures that appear to be separated by a longitudinal fissure running from the front to the back of the brain.
KK 5B – PAGE
The left and right hemispheres of the brain are not only alike in overall size, shape and structure, but also have many of the same functions
Each hemisphere has a specific area responsible for motor and sensory functions

7. THE CEREBRAL CORTEX CORPUS CALLOSUM
A band of nerve tissue that connects the left and right cerebral hemispheres and serves as the main communication pathway between them
Acts as a ‘bridge’ for neural messages
between the two cerebral hemispheres
