Neurotransmitters
This neurotransmitter influences movement, learning, attention, and emotion.
What is dopamine?
These are the three steps to a reflex.
What are sensory neurons, then interneurons, then motor neurons?
This hemisphere controls the right side of the body.
What is the left hemisphere?
Neurotransmitters are typically stored in this part of the neuron.
What are the terminal branches of the axon?
This brain imaging technique uses x-rays to generate images of the brain and is usually used to locate brain damage.
What is a computed tomography (CT) scan?
This is the result of an oversupply of endorphins with opiate drugs.
What is the suppression of the body's natural endorphin supply?
This part of the nervous system consists of the brain and the spine.
What is the Central Nervous System (CNS)?
This cortex registers sensory information from the body, including touch, pain, temperature, and body position.
These types of neurons process and connect information within the central nervous system (CNS).
What are interneurons?
This brain imaging technique records the waves of electrical activity across the brain's surface through electrodes placed on the scalp.
What is an electroencephalogram (EEG)?
This is a common function between the neurotransmitters acetylcholine and glutamate.
What is memory?
This branch of the autonomic nervous system increases physiological arousal during stressful situations, including increasing heart rate and slowing digestion.
What is the Sympathetic Nervous System (SNS)?
This structure of the brain is a relay station for incoming and outgoing sensory information (with the exception of smell).
What is the thalamus?
This is the level of stimulation required to produce an impulse, with more stimulation not producing a stronger impulse.
What is a threshold?
These brain imaging techniques are used to show neurological function.
What are EEGs, MEGs, PET scans, and fMRIs?
This is a major inhibitory neurotransmitter, whose undersupply has been linked to seizures, tremors, and insomnia.
What is gamma-aminobutyric acid (GABA)?
This process occurs when neurotransmitters released into the synapse are taken back into the sending neuron for reuse.
What is reuptake?
This structure that is a part of the brain stem is also a part of the autonomic brain system. It controls one's heartbeat and breathing.
What is the medulla?
These are the functions of glial cells. (Note: At least 3 of 4 correct functions required to earn 400)
What are providing structure/protection, insulation (myelin), waste removal, and communication support?
This process provides information regarding brain function by monitoring the brain at work through metabolism of glucose.
What is a PET scan?
Through intense research procedures, Dr. Dunker, with the help of multiple unethical procedures, discovered that these two neurotransmitters both uniquely share a common function: arousal.
What are serotonin and norepinephrine?
The nervous system uses fast-acting electrical impulses and neurotransmitters for rapid responses. These electrical impulses are the messengers, and the responses are very localized. However, in contrast, this system uses hormones as messengers that target cells in the bloodstream.
What is the endocrine system?
A patient damaged a certain part of the brain. They've been struggling to plan for the future and have been making very poor judgement. An MRI denotes that a certain lobe of the processing center of the brain has been damaged.
What is the frontal lobe?
Glial cells form myelin, so when myelin breaks down the neuron itself still exists but its signal slows or misfires. Myasthenia gravis (MG) involves a breakdown at the junction where motor neurons signal muscles using acetylcholine. However, unlike MG, this disorder is specifically based on the deterioration of the myelin sheath, which leads to motor impairments.
What is multiple sclerosis?
A cognitive neuroscientist wants to compare the overall physical volume of the hippocampus in individuals diagnosed with a major depressive disorder versus a healthy control group, without measuring real-time neural activity or blood flow, and without ionizing radiation. This imaging technique would be the most appropriate for this structural measurement.
What is a MRI?
