The part of the neuron that sends an electrical signal to the terminals.
What is an axon?
Bundles of axons that make up the nervous system.
What are nerves?
This organ is cleaned by cerebrospinal fluid during sleep.
What is the brain?
This psychoactive substance is an adenosine antagonist and commonly found in plants like tea and coffee.
What is caffeine?
This lobe of the brain is known as "the seat of personality" and deals with higher level cognition and function.
What is the frontal lobe?
The "receivers" on a neuron.
What are dendrites?
The part of the nervous system that contains the brain and the spinal cord.
What is the Central Nervous System?
This stage of sleep is characterized by a transition from wakefulness to sleep.
What is Stage/Step 1 NREM sleep?

What is the occipital lobe?
The name of the fatty, insulator around axons.
What is myelin?
This part of the nervous system contains everything outside of the brain and spinal cord.
What is the Peripheral Nervous System?
This stage of sleep is characterized by the slowing of brain waves, interspersed with spikes of activity.
What is Stage/Step 2 NREM sleep?
This substance potentiates GABA receptors and suppresses glutamate receptors to create an inhibitory effect on neurons.
What is ethyl alcohol or Ethanol?
This lobe of the brain processes sensory information, including touch.
What is the parietal lobe?
The process by which a neuron sends an electrical signal to its axon terminals.
What is an action potential?
These nerves carry signals away from the CNS to the PNS.
What are efferent nerves?
This stage of sleep is what is considered "deep sleep" and is what is required to feel rested.
What is Stage/Step 3 NREM sleep?
This class of drugs work by activating dopamine release and blocking pain receptors.
What are opioids?
This lobe of the brain houses a wide variety of functions, including memory creation and storage, understanding language, and hearing.
What is the temporal lobe?
The resting membrane voltage of a neuron.
What is -70mV?
These nerves carry signals from the PNS to the CNS.
What are afferent nerves?
This stage of sleep is characterized by a massive spike in brain activity and erratic movement of the eyes.
What is Rapid Eye Movement (REM) sleep?
These psychoactive substances profoundly alter consciousness, resulting in changes in mood, hallucinations, and serotonin and dopamine release.
What are psychedelics?
The three main parts of the brain.
What are the cerebrum, cerebellum, and brainstem?
