Genetics & Evolution
These psychologists study changes in behavior and thinking over time.
Who are evolutionary psychologists?
The electrical signal that travels down a neuron’s axon.
What is an action potential?
This neurotransmitter plays a role in pleasure and pain reduction.
What is beta-endorphin?
The two major divisions of the nervous system.
What are the central and peripheral nervous systems?
Folds and grooves on the brain’s surface.
What are gyri and sulci?
This theory explains how organisms better suited to their environment survive and reproduce.
What is evolution by natural selection?
The space between two neurons.
What is the synapse?
These two neurotransmitters help suppress appetite.
What are dopamine and norepinephrine?
This system is responsible for fight-or-flight responses.
What is the sympathetic nervous system?
The idea that brain hemispheres have different functions.
What is lateralization?
Human eggs and sperm contain 23 of these structures made of DNA.
What are chromosomes?
The difference in charge between inside and outside a neuron.
What is membrane potential?
This process removes neurotransmitters from the synapse.
What is reuptake?
This system is responsible for digestion and relaxation.
What is the parasympathetic nervous system?
The brain area responsible for speech production.
What is Broca’s area?
Wendy has blue eyes even though brown is dominant—her genotype must be this.
What is bb?
What hyperpolarization means.
What is becoming more negative than resting potential?
This neurotransmitter is affected by SSRIs.
What is serotonin?
The system involved in voluntary movement.
What is the somatic nervous system?
The brain process not controlled by the cerebral cortex.
What is breathing?
This concept says genes set limits, but the environment determines outcomes within them.
What is the range of reaction?
If a signal doubles in strength, the action potential does this.
What is no change in strength, speed, or duration?
One thing that does not happen to excess neurotransmitters.
What is collection by scavenger vesicles?
This term means the body maintains internal balance.
What is homeostasis?
The brain system strongly connected to smell and emotional memories.
What is the limbic system?
