THE BRAIN

GETTING IN TOUCH WITH YOUR BRAIN

• The human brain weighs about 1.5kg in adults• It has the consistency of firm jelly and is covered by

strong, plastic like membranes• There is a small gap between the brain and the skull

which is filled with fluid• The fluid provide a cushion against knocks to the head,

protecting the brain from damage unless the knock is quite hard

THE CEREBRUM

• It occupies more than 80% of the brain

• It is here that the higher intellectual functions of humans take place

• It controls your conscious thoughts and voluntary movement of every body part, and sensory messages from all body parts

• The cerebrum is made up of two parts called the right and left cerebral hemispheres

RIGHT HEMISPHERE

• Controls the left side of the body

• This is where visual special skills are coordinated, dancing and gymnastics are coordinated

• Memory is stored in auditory, visual and special modalities

LEFT HEMISPHERE

• Controls the right side of the body

• Systematic, logical interpretation of information; interpretation and production of symbolic information

• Language, mathematics, abstraction and reasoning

• Memory stored in a language format

THE CEREBRUM

•There are 4 lobes:•Frontal•Parietal•Occipital•Temporal

FRONTAL LOBE

• Responsible for conscious thought, cognition and memory• Controls the ability to concentrate, higher intellectual reasoning, aggression, judgement and inhibition• Plays a role in personality and emotional traits

TEMPORAL LOBE

•Receives and evaluates input for smell and hearing and plays an important role in memory

PARIETAL LOBE

•Responsible for processing of sensory input and sensory discrimination•Plays a part in orientation

OCCIPITAL LOBE

•Primary visual reception and interpretation area

CEREBELLUM

• Is like a smaller version of the cerebrum and is responsible for movement, balance and coordination

THE BRAINSTEM

• Sits mostly inside the brain • At its base it becomes the spinal cord• The brainstem is made up the three major parts: the medulla, the pons and the midbrain

THE MEDULLA

• Its at the bottom of the brainstem and automatic functions, like respiration and digestive system activities

PONS

•Assists in some automatic functions, like breathing, and also controls sleep and arousal

MIDBRAIN

•Contains areas that receive and process sensory information, such as movement and vision

RETICULAR FORMATION

• Controls sleep and wake cycles•Damage to this area may result in a coma• Plays a role in alertness, fatigue, and motivation to perform various activities

HYPOTHALAMUS

•Maintains constant heart rate, body temperature and sleep pattern• It is also involved in hormone production by control of the pituitary gland

THALAMUS

•Process and carries messages for sensory information, such as information sent from the ears and skin to the cortex
