Neurons
A neuron receives information from other neurons through these branch-like extensions
What are dendrites
This neurotransmitter is associated with muscle movement and is involved in learning and memory.
This brain structure controls essential survival functions such as breathing and heartbeat.
This lobe is primarily responsible for processing visual information.
What is the occipital lobe
This stage of sleep is characterized by rapid eye movements and is commonly associated with vivid dreaming.
What is REM sleep
When a neuron receives enough stimulation to reach this threshold, it fires an electrical impulse that travels down its axon.
What is threshold
A student feels motivated to pursue a reward after receiving positive feedback on a project. This neurotransmitter plays an important role in the brain's reward system, motivation, and movement.
What is dopamine
A student loses their balance and struggles to coordinate movements after a brain injury. Which brain structure is most likely damaged?
What is the cerebellum
A patient understands what someone is saying but struggles to produce meaningful spoken language. Damage to which brain area is most likely responsible?
What is Broca's area
A student falls asleep and experiences the sensation of suddenly falling, causing their body to jerk awake. This phenomenon is called what?
What is hypnagogic sensation
A medication prevents the reabsorption of serotonin into the sending neuron, leaving more serotonin available in the synapse. What process has the medication blocked?
What is reuptake
A student experiences a sudden surge of energy and increased heart rate after narrowly avoiding a car accident. Which neurotransmitter is associated with this heightened alertness and arousal?
What is norepinephrine
A student smells cookies baking and suddenly remembers visiting their grandmother as a child. Which limbic system structure plays an important role in forming and retrieving these memories?
What is the hippocampus
After suffering a stroke, a patient can feel someone touching their left hand but cannot identify where the sensation is coming from. Which area of the cerebral cortex is most likely damaged?
What is their right somatosensory cortex
A student consistently gets only four hours of sleep per night. Over time, they struggle to concentrate, remember information, and regulate their emotions. What concept explains the accumulating effects of insufficient sleep?
What is REM rebound
A disease damages the fatty substance surrounding the axons of neurons. As a result, neural messages travel much more slowly. What structure has been damaged, and what is its normal function?
What is the myelin sheath
A patient experiences chronic anxiety and difficulty regulating their mood. A doctor suspects that unusually low levels of an inhibitory neurotransmitter are contributing to the symptoms. Which neurotransmitter may be deficient?
What is GABA
After a frightening experience, a person becomes extremely alert whenever they hear a similar sound. Which limbic system structure is most directly involved in processing the fear associated with this experience?
What is the amygdala
Following a stroke, a patient can speak fluently, but their sentences often make little sense. They also struggle to understand what other people are saying. What brain area has likely been damaged?
What is Wernicke's area
During a sleep study, a researcher observes a participant entering a stage characterized by sleep spindles and K-complexes. Which stage of sleep is the participant experiencing?
What is NREM Stage 2
A researcher stimulates a neuron repeatedly. The neuron initially fires, but after a particularly intense action potential, it cannot immediately fire again, regardless of how much additional stimulation it receives. What is this period called, and why does it occur?
What is the refractory period
A patient takes a medication that mimics the effects of a neurotransmitter by binding to its receptor sites. Explain whether this medication is acting as an agonist or antagonist and how it affects neural communication.
What is an agonist
A patient develops an injury to the ventromedial hypothalamus, resulting in significant changes in their eating behavior. What effect would you expect this damage to have on the patient's hunger and eating habits?
What is increased hunger and overeating
A patient suffers damage to the frontal lobe and begins demonstrating poor judgment, impulsive decision-making, and difficulty planning for the future. Which area of the brain is most likely damaged?
What is the prefrontal cortex
During a sleep study, researchers observe a participant exhibiting very slow brain waves with high amplitude. The participant is difficult to wake, and this stage of sleep is associated with physical restoration and the consolidation of declarative memories. What stage of sleep is the participant experiencing?
What is NREM Stage 3
