Question 30

two types of neural development

1. adaptive plasticity 2. developmental plasticity

Question 31

adaptive plasticity

Answer 31

happens after birth long-term potentiation 2 types: structure and functional changes

Question 32

structural changes | of adapative plasticity

Answer 32

dendrites branching out + more receptors axon branching

Question 33

functional changes

Answer 33

more neurotransmitters produced and released

Question 34

long term depression

Answer 34

occurs when a pathway hasn't been used very often, becomes weaker over time

Question 35

rerouting

Answer 35

healthy neurons nearby create alternative routes

Question 36

sprouting

Answer 36

existing neurons form new axon terminals and dendrites to make new connections

Question 37

developmental plasticity

Answer 37

internally programmed before birth

Question 38

types of ABIs

are tbis and ctes the same

Answer 39

NO CTE is a progressive and fatal brain disease associated with TBIs

Question 40

concussion

Answer 40

a TBI caused by a bump, blow, or jolt to the head or by a hit to the body that causes the head and brain to move rapidly back and forth

Question 41

stroke

Answer 41

an interruption of blood supply to the brain blood clot OR narrowing of blood vessels FAST

Question 42

CTE

Answer 42

neurodegenerative tau protein atrophy shrinkage of gray matter | chronic traumatic encephalopathy

Question 43

aphasia

Answer 43

language disorder that's caused by damage to the Broca's or Wernicke's area | broca = production, wernickes = expression
