Vocab 501-550 Flashcards
Located in the left frontal lobe; controls muscles involved in producing speech; damage prevents speech production
Broca’s Area
Located in the left temporal lobe; interprets written and spoken speech; damage would affect our ability to understand language
Wernicke’s Area
Thin vertical strip located at the back of the frontal lobe; controls voluntary movements by sending signals to our muscles
Motor Cortex
Thin vertical strip located at the front of the parietal lobe; receives signals from throughout our bodies
Sensory Cortex
What are the four parts of the Limbic System?
Thalamus
Hypothalamus
Hippocampus
Amygdala
Filters incoming external sensory information
Thalamus
The volume of a person’s thalamus correlates with what disorder?
Attention Deficit Hyperactivity Disorder (ADHD)
Filters incoming internal sensory information; tells us when we are thirsty
Hypothalamus
Converts short-term memory (working memory) into long-term memory
Hippocampus
Regulates our emotions, especially fear
Amygdala
A neuron (nerve cell) that fires a neurotransmitter as a result of an action potential entering its axon terminal
Presynaptic Neuron
A neuron (nerve cell) that receives a neurotransmitter after it has crossed the synapse
Postsynaptic Neuron
Kind of neurotransmitter that has an inhibitory effect on other neurons; they decrease the likelihood that the neuron will fire on an action potential
Inhibitory Neurotransmitter
Kind of neurotransmitter that has an excitatory effect on other neurons; they increase the likelihood that the neuron will fire on an action potential
Excitatory Neurotransmitter
Type of antidepressant medication that works by increasing the levels of serotonin within the brain
Selective Serotonin Reuptake Inhibitor (SSRIs)
Using drugs, having sex, and eating cheeseburgers can all activate the brain’s reward pathway. What neurotransmitter fuels the reward pathway?
Dopamine
A lack of this neurotransmitter correlates with Parkinson’s Disease
Dopamine
An excess of this neurotransmitter correlates with Schizophrenia
Dopamine
A dopamine agonist (L-DOPA) would most likely be prescribed to treat what disorder?
Parkinson’s Disease
A dopamine antagonist (Chlorpromazine) would most likely be prescribed to treat what disorder?
Schizophrenia
