Neurons & NTs
The part of the neuron that speeds up action potentials and protects the axon.
What is the myelin sheath?
The part of your nervous system responsible for voluntary movement
What is the somatic nervous system?
The main functions of your right hemisphere (name at least 2)
spatial processing
visual-spatial tasks
recognizing patterns and faces
These brain waves are associated with being awake, alert, and actively thinking.
What are beta waves?
This part of the brain acts as a relay station for nearly all sensory information headed to the cerebral cortex, except smell.
What is the Thalamus?
This type of drug mimics or enhances a neurotransmitter's effects.
What is an agonist?
The impact of the sympathetic nervous system on the digestive tract
What is the slowing of digestion
This brain structure is responsible for balance and coordination.
What is the cerebellum
After repeatedly using a drug, a person experiences unpleasant physical or psychological symptoms when they stop taking it.
What is withdrawal?
Too much of this neurotransmitter is linked to alzheimer’s disease
What is acetylcholine (ACh)?
The name of the type of neurotransmitter that decreases the action potential of other neurons.
What are inhibitory neurotransmitters?
A hormone produced that makes you feel hunger
What is ghrelin?
Damage to this part of the brain leads to jumbled speech and word salads
What is Wernicke’s Area (Wernicke’s Aphasia)
A student is awakened during the night and reports vivid dreams. The student was likely awakened during this stage:
What is REM Sleep
Two physical features of Stage 3 sleep
Examples include:
Slow brain waves
Decreased heart rate, respiration, blood pressure
Very difficult to wake
When a neuron must rest and reset before it can send another action potential.
What is the refractory period?
When Jake smells a freshly baked loaf of bread and takes a bite, this is the order of signals in his nervous system
Nose (sensory neurons) → spinal cord (interneurons) → Brain → spinal cord → action (motor neurons)
The part of your brain responsible for keeping your 24 hour bodily cycle (extra point for naming the cycle)
What is the suprachiasmatic nucleus (+circadian rhythm)
A person experiences altered perceptions and sensory experiences after taking this substance.
What is a hallucinogen
This brain-imaging technique would best show which parts of the brain become active as people solve difficult questions
fMRI
Too little of this neurotransmitter will lead to Parkinson’s disease
What is Dopamine?
The network of glands and organs that release chemicals into the bloodstream (extra point for naming the master gland)
What is the endocrine system (+ pituitary gland)
A student watches a classmate solve a difficult puzzle and then begins using the same strategy. The main neurons responsible for this copying of behaviour
What are mirror neurons
A person walks around the house while still asleep and has little or no memory of the event the next morning.
What is sleep walking (Somnambulism)
This drug is a type of opioid and used to relieve severe pain
What is morphine?
