Brain Development
By: Farhana T. Macataman
Brain Development
•It begins shortly after conception and continuous through the life span
•Maybe affected through sensing pathways by sound, touch, vision, smell, and thoughts.
•The important aspects of brain is the ability to change during young age.
The Brain
Brain
The Human Brain•Frontal lobe –
voluntary movement,thinking, and personality
•Parietal lobe - speech, language, attention, sensation, motor control
•Occipital Lobe- Vision
•Temporal Lobe - hearing, language and memory processing
Early Childhood Rapid change of brainProcess of myelination continue and brain
size increaseBrain Plasticity Flexible and prepared to learnBlooming and Pruning
Early Childhood
3 years – Most rapid changes due to bombardment of experiences - Brain is ¾ of adult size - 1090 grams for famale brain - 1270 grams for male brain
Early Childhood4 years old – brain increase 80% of adult
size - Temporal Lobe (auditory
myelination is complete)5 years Old - Occipital lobe reaches adult
levels
Early ChildhoodEffects of Neglect and/ or abuse
- the frontal lobe develops improperly when deprived of affection and positive emotional experiences
- Lack of stimulation causes neurons in the brain to die off
Effects of Neglect and/ or abuse
Middle Childhood•Brain volume stabilizesWeight : 1440 grams in male
1260 grams in female6- 7 years old –maturation of occipital
lobe - Contrast sensitivity and peripheral vision reach adult levels
8 years old- maturation of temporal lobeBrain maintain flexible for future learning
Adolescence
•Transition from childhood to adulthood•Social, psychological and emotional
changes accompany by puberty•Selective pruning takes place - Frontal lobe loses 3%•Myelination- allows to operate more
effeciency•Emotional Control
Amygdala- Holds emotional memory - develops before frontal develops
Adolescence•Teens experience a greater desire and
need to thrill-seeking than any other age group
Genetics and Environment•There is an evident that early experience
can dramatically alter the genes are expressed in developing brain
•Teens experience is a greater desire & need to thrill-seeking than any other age group
