development in adolescence
Question | Answer |
---|---|
• Cerebellum | There is an increase in the number of neurons and synapses in the cerebellum the pat of the brain responsible for- Balance, Muscle tone, Performance of motor skills This might explain why some teenagers are more physically uncoordinated than adults |
• Amygdala | Becomes more active in adolescence. Is commonly thought to form the core of a neural system for processing fearful and threatening stimuli. |
amygdala includes | Including detection of threat and activation of appropriate fear-related behaviours in responseto threatening or dangerous stimuli |
• Corpus callosum | o The corpus callosum thickens and there is an increase in the number of connections (nerve fibres) between the two hemispheres |
• Frontal lobe | o The forntal lobe is responsible for motor movemnt and higher order thinking |
Frontal lobe development on behaviour and emotion | The prefrontal cortex is the last to develop. It is responsible for impulse control, risk management and critical thinking - the reason why adolescence can be vey impulsive delayed ability to make safe decision why p platter shave hard rules |
Frontal lobe development on behaviour and emotion - amygdala | before prefrontal cortex develops, the adolescent brain relies on the amygdala, which plays an important role in processing our emotions hyper-emotional state & bad decisions we make (teenage) coz amygdala not frontal |
Frontal lobe development on behaviour and emotion | continue to mid twneties. sensitive perioods - optimum times to learn things. specific stimulation needed to establish neural patthways. genie the wild child |
