A patient who can speak fluently but without meaning likely has damage to this hemisphere of the brain
What is the left hemisphere?
200
Neurons are the primary component of this major body system
What is the nervous system?
200
If a bear jumps out at you when you leave school today, your body will trigger a response commonly known by this active name
What is fight or flight?
200
Many drugs are active in this space between two neurons
What is the synapse?
200
The debate about whether our characteristics are the result of heredity or environment is commonly known by this name
What is nature vs. nurture?
400
This lobe of the brain sits farther from the eyes than any other brain structure -- odd, since that is where visual information is processed
What is the occipital lobe?
400
This structure, labeled #4, protects the axon and speeds electrical impulses with the neuron
What is myelin?
400
This subdivision of your autonomic nervous system is responsible for the stress response
What is the sympathetic nervous system?
400
Many drugs have an impact on these chemical messengers that travel between neurons
What are neurotransmitters?
400
We inherit 23 of these miniscule structures, which carry all of our genetic information, from each of our parents
What are chromosomes?
600
The cerebrum is in this direction from the spinal cord
What is superior?
600
These tendrils, which receive information from other neurons, extend outward from a neuron's body like the branches of a tree
What are dendrites?
600
You can limit your exposure to chronic stress by engaging this subdivision of your autonomic nervous system, which is responsible for "rest and digest" processes
What is the parasympathetic nervous system?
600
The active ingredient in this drug mimics anandamide, a naturally occuring cannabinoid in the brain
What is marijuana?
600
These units of DNA contain the instructions for how our bodies work
What are genes?
800
The cerebellum is in this direction from the brain stem
What is caudal or dorsal or posterior?
800
Electrical impulses pass along this long structure within the neuron
What is the axon?
800
If you experience something stressful, this brain structure will send a signal to your hypothalamus, kicking off your stress response
What is the amygdala?
800
Heroin, meth, cocaine, and marijuana all have an impact on this chemical messenger, which is a an important element of the rewards pathway
What is dopamine?
800
Not all of the genetic code in your genotype is expressed; the characteristics that you actually have as a result of the interaction of your genotype and your environment are given this name
What is the phenotype?
1000
The amygdala, hippocampus, thalamus, and hypothalamus are among the many structures that make up this system, which is largely responsible for the stress response
What is the limbic system?
1000
White matter contains mostly axons; gray matter is mostly made of these neuronal structures
What are cell bodies OR soma?
1000
When this, the body's primary stress hormone, surges through the body, it's time to take a few deep breaths
What is cortisol?
1000
Alcohol use can impact impulse control and memory formation by "shutting down" this part of the brain, which is involved in higher-order processing and cognition
What is the prefrontal cortex OR the frontal lobe?
1000
Early adherents of behavioral genetics were inspired by their findings that intelligence is heritable to develop plans for selective breeding of humans, a practice known by this name
What is eugenics?
