THE POWERS OF THE MIND
LESSON 6
THE BRAIN AND ITS HEMISPHERES
“ The most complex living structure
on the universe” Society for Neuroscience
The brain and the Spinal Cord is
located in the Central Nervous
System (CNS)
The average weight of the brain is
three (3) pounds or 1,350 grams
and has a jelly like consistency.
Has two hemispheres, the LEFT
HEMISPHERE and the RIGHT
HEMISPHERE which are responsible
for different skills.
LEFT HEMISPHERE RIGHT HEMISPHERE
- The right brain is dominant for
- The left side of the brain is
spatial abilities, face recognition, visual
responsible for controlling the right imagery and music. The right side of
side of the body. It also performs the brain is responsible for controlling
tasks that have to do with logic, the left side of the body and may be
such as in science and more dominant for creativity,
mathematics like calculations. imagination, rhythm, feelings.

FOUR LOBES OF THE BRAIN
PARIETAL LOBE
FRONTAL LOBE
OCCIPITAL
LOBE
TEMPORAL LOBE
FRONTAL LOBE
FRONTAL
LOBE It is one of the area of the cerebral
cortex that is located in the front
and top of the brain.
Its functions include:
higher mental processes
decision making
recognition and formulation of
speech
involuntary motor movements
known as the Brocas’ area (named
after Paul Broca)
TEMPORAL LOBE
Areas of the cerebral cortex located
just behind the temples
Contains the neurons responsible for:
Sense of hearing
Meaningful speech
TEMPORAL LOBE It is also responsible for explicit
memory
known as the Wernicke’s area
(named after Carl Wernicke)
OCCIPITAL LOBE
located at the rear bottom of
each cerebral hemisphere
Containing the visual centers of
the brain
OCCIPITAL
LOBE
PARIETAL LOBE
PARIETAL LOBE
Located at the top and back of
each cerebral hemisphere
It controls touch,
Taste, and
Temperature sensations
Activities that can enhance the Right
Brain and the Left brain
Left
Puzzles
Taking advance courses in mathematics
Reading books
Declaiming or public speaking
Right
Dancing
Painting or crafting
Playing instrument
NEUROTRANSMITTERS
Are chemicals that carry messages across the synapses
or cell body of a receiving neuron.
1. SEROTONIN – Helps in sleep, memory, mood and relaxation.
2. DOPAMINE – Provide pleasure and motivation, motor control and
movement.
3. ACETYLCHOLINE – controls the arousal, attention, memory, and
muscle contractions of the body.
4. ENDORPHINS – involved in pain relief (pain management)
5. GABA (Gamma Amino Butyric Acid) – involved in sleep and inhibits
movement.
6. 6. Oxytocin- regulates social interaction and sexual reproduction;
referred as the “love hormone”.
WHAT ARE GLANDS?
GLANDS- an organ in the human or animal body that secretes particular
chemical substances, called hormones, for use in the body of for discharge
into the surroundings.
*Divided into 2 groups based on their function:
1. EXOCRINE GLANDS- secrete substances out of the body
2. ENDOCRINE GLANDS- secrete substances that circulate through the blood
stream.
