BiopsychologyQuestions – 100%
Correct, Expert Verified Answers with
A+ Grade Assurance
Nervous system ANSW ✔✔ Bundle of cells, neurons working together

Brain: communication and structure
Network of neurons
Specialized cells to receive and send info



Neuron structure ANSW ✔✔ - review handout -
Axon terminal buttons - sends out NT (message)
NT received by post synaptic dendrite
Some NT fit receptor sites
When threshold met sends NT message, triggers action potential of post-synaptic neuron


When post-neuron fires, release NT for re-uptake
Enzymes breakdown excess NT
(Allows post-synaptic neuron to re-polarize



Brain plasticity ANSW ✔✔ Brains ability to change and adapt

1. Learning - new dendrites grow more cortex for functions
2. Repairing damage - right hem takes on language if left hem damaged
3. Substitution of function - babies w/o corpus callosum can still coordinate 2 sides of brain



Sprouting ANSW ✔✔ Axon branches grow new connections to compensate for damaged
neurons



Neurogenesis ANSW ✔✔ New neurons are generated
Only in hippocampus and olfactory bulb
