Nature v. Nurture
This term describes when the environment triggers or suppresses genetic traits
Gene expression
The body’s electrochemical communication network is called this
The nervous system
This ion rushes into the neuron during depolarization
Sodium (Na+)
This neurotransmitter is most associated with addiction pathways
Dopamine
Alcohol belongs to this drug category
Depressants
The idea that identical genes can lead to different outcomes depending on experience
This division controls involuntary actions like heart rate
This ion exits the neuron during repolarization.
Potassium (K+)
Continued use leading to needing more of a drug is called this
Tolerance
LSD and psilocybin fall under this category
Hallucinogens
A child genetically predisposed to anxiety developing it only under stress shows this
Interaction of heredity and environment
The neuron’s cell body is also known as this
The soma
Vesicles store these chemicals before release into the synapse
Neurotransmitters
Physical or psychological need for a drug is this
Dependence
The wrinkled surface of the brain increases this
Surface area
This term refers to the relative contribution of genetic inheritance to individual differences in traits within a population.
Heritability
These channels open during neural firing to allow ions in and out
Ion channels
This process describes the neuron becoming more negatively charged again after an action potential
Repolarization
Symptoms experienced after stopping a drug
Withdrawal
The left hemisphere typically specializes in this function
Language
The brain’s interpretation of sensory input is this
Perception
This type of signal makes a neuron less likely to fire
Inhibitory signal
This minimum level of stimulation must be reached for a neuron to trigger an action potential.
Threshold
This class of drugs includes caffeine and nicotine
Stimulants
The right hemisphere is often associated with this ability
Spatial processing
