Integrating Science Flashcards
What part of the brain is damaged by forward motion?
Prefrontal lobe
What part of the brain is damaged by side to side shifting?
Temporal lobe
What is damage to the temporal lobe primarily responsible for producing?
Emotional lability and impulsivity
What sense is associated with more intense memories?
Smell
What is the cerebellum responsible for?
Complex behavioral algorithms
What is the Coolidge effect?
Mrs. Coolidgediscovered that roosters exposed to novel hens copulate furiously then lose interest
What is serotonin responsible for?
Mood, sleep, pleasure, appetite, and memory
What is dopamine responsible for?
mood, reward circuits, sleep, pleasure, and voluntary movement
What is sensory gating?
The ability to filter stimuli and choose what you attend to.
Damage to the prefrontal lobe typically causes what?
Impaired executive functioning
How do stimulants cause serotonin and dopamine flooding?
Stimulants speed up the release of neurotransmitters making them flood the synapse.
What is the most powerful stimulant in terms of creating flood?
Extasy
What is the least powerful stimulant?
Caffeine
Why do users crash after using stimulants?
Neurotransmitters get caught up in re-uptake - making them unavailable for use
What are the effects of neurotransmitter flooding?
Free radical production –> free radicals kill or stun cells
Why is it dangerous for nerve cells to be frequently stunned?
Nerve cells that are repeatedly stunned eventually die.
How do neurotransmitters affect mania?
Flooding increases the amount of neurotransmitters in the synapse, which produces symptoms of mania.
How do neurotransmitters affect depression?
Clients may be born with too little reserves of neurotransmitters or they may be depleted due to prolonged stress.
How does long term exposure to high stress affect the brain?
The amygdala shrinks after long-term exposure to cortisol.
How many items can a normal individual hold in working memory?
7+ or - 2 chunks
What types of memory is there?
Attention, working memory, short term, and long term memory.
