Chapter 5 - Neuropsychology Flashcards
What does Dopamine do?
Neurotransmitter. Influences movement learning, attention, and emotion. Excess dopamine leads to schizophernia.
What does Acethycholine do?
Neurotransmitter. Enables muscle action, learning and memory. Linked to problems with transferring information from the spine.
What does Serotonin do?
Neurotransmitter. Affects mood, hunger, sleep, and arousal. Too little Serotonin leads to depression.
What does Endorphin do?
Neurotransmitter. Helps control alertness and arousal. Undersupply can depress mood, Endorphins created by continuous excersizing.
What does gamma-aminobutyric acid do?
Major neurotransmitter. Undersupply leads to seizures, tremors, ad insomnia.
What does Glutamate do?
Memory neurotransmitter. Oversupply leads to migraines or seizures. Caused by MSG.
What does an Agonist do?
Agonists increase Neurotransmitter count. Agonist is an assist character. Agon.
What does an Antagonist do?
Antagonists block Neurotransmitters. It is literally the antagonist.
Three major categories used to organize the entire brain
Brain stem, limbuc system, and cerebral cortex
Spinal reflex differs from a normal sensory and motor reaction from their
Spinal reflex. The spine moves as soon as sensory information reaches the spine. The impulse must reach the brain before a response.
What scan should be used for the connection between certain enviromental stimuli and brain processes?
PET and EEG
Split brain patients are unable to…
Sprak about information in their right brain hemisphere.
What is brain plasticity?
New connections forming in the brain to take over for damaged sections.
What is a specific function of the left brain that can not be controled by the right hemisphere?
Producing of speech.
The resting state of neuron (when mostly negative ions are inside and mostly positive ions are outside) is referred as…
Polarized.
