Development Flashcards
(91 cards)
Stages of brain development
pregnancy
- 1-4 weeks
- 5-8 weeks
- 9-12 weeks
- 13-20 weeks
- 21-28 weeks
- 29-40 weeks
Brain development - weeks 1-4 of pregnancy
- neural plate forms
- begins to fold onto itself forming neural tube
Brain development - weeks 5-8 of pregnancy
Neural tube divides into spinal cord, forebrain, midbrain, hindbrain
Brain development - weeks 9-12 of pregnancy
Brainstem develops, controlling reflexes like sucking/swallowing
Brain development - weeks 13-20 of pregnancy
- brain cells multiply quickly
- cortex starts forming
Brain development - weeks 21-28 of pregnancy
Gains sensory awareness, responds to sound and touch
Brain development - weeks 29-40 of pregnancy
- brain gets ready for birth
- connections + memory abilities improve
When is the brain fully formed but not at full size
6 months
What size is brain at birth compared to adult’s
25%
Brain stem
Controls autonomic functions
Autonomic functions
- done automatically, without thinking about
- e.g- breathing
Thalamus
- sensory processing station
- receives sensory information, translates them to behavioural and motor responses
Cerebellum
- coordinates movement and balance
Cortex
- surface layer of brain
- where brain processing takes place
4 lobes
- frontal
- parietal
- occipital
- temporal
Frontal lobe
Controls thought, planning, memory, problem solving
Parietal lobe
Processes sensory information from the body
Occipital lobe
Processes visual information
Temporal lobe
Understanding and producing spoken language
Nature
- traits, characteristics and behaviours inherited genetically
- present at birth
Nature Research
- research on twins
- genetically similar people share similar cognitive characteristics like IQ
- supports idea genes influence brain development
Nurture
Traits, characteristics, behaviours resulting from environmental influences
Nurture Research
- research shows how mother’s actions during pregnancy affect brain development
- mothers smoking when pregnant risk babies having smaller brains - nicotine slows brain growth
- shows environmental influences affect brain development
