Depressants (ex: alcohol) slow down the nervous system.

A small part of the brain, located in the limbic system. In charge of emotions, (fear, aggression).

Taking these results in false sensory experiences. (ex: LSD, Shrooms, Marijuana)

Caused by sleep deprivation, makes you spend more time in REM sleep.

Detects and records electrical impulses (electrodes) in the brain.

A state of narrow and focused consciousness, with a heightened susceptibility to suggestion.

Electronic image of the brain and it's structure. (Can't show brain activity.)

Neurotransmitter causing alertness, focus, and a sense of relief.

Freud's theory that dreams the outlet for unacceptable unconscious desires.

All nerves outside of the brain and spinal cord.

Connects across the synapse with the dendrites of other neurons.

Which of the following ISN'T a sleep theory?

Protective fatty tissus surrounding the axon, increases the speed of the transmission.

Calms your body after a fight or flight response. (slows heartbeat, restores normal body functions)

______ is in charge of motor functions, balance, and coordination.

Bushy branches of a neuron that receive messages from other neurons.

Lightest sleep stage, occurs right after we fall asleep. Brief false sensory experiences and hypnic jerks.

Communication neurons in the spinal cord. Controls reflexes (stops afferent neurons & sends out immediate efferent ones)

Inhibitory neurotransmitter. Slows down neurons.

Theory that dream content reflects changes in cognitive development as people age.

Rapid eye movements, most dreams occur here, accounts for 25% of the nights sleep, and muscles are paralyzed.

Left Hemisphere (Two Answers)

Activates fight or flight. (fast heartbeat, dilated pupils, high blood pressure, adrenaline, goosebumps, sweating)

Neurons carrying information about the senses.

Biological clock that regulates body rhythms on a 24-hour cycle.

Measures brain activity by recording the changes in blood flow.

Processes touch, pressure, pain, and temperature.

Neurotransmitter involved in trust and relationship building.

Planning, problem solving, personality, decision making, speech production.

Chemical or drug that binds to the receptors in the brain to cause a reaction.

Most abundant neurotransmitter. Invloved in movement, memory, and learning. (Too little = Alziemers)

Deepest stage of sleep, brain emits delta waves. Sleep-walking, bedwetting, and night-terrors can occur.

In charge of processing memories. Part of the limbic system.

____ is when a neuron "fires". A positive charge goes down the axon and "triggers" the terminal buttons.

Receives and processes auditory information.

All senses (excluding smell) must pass through the _____________ before being directed to the correct part of the brain.

Theory that dreams are to help us sort through daily events and consolidate our memories.

Receives and processes visual information.

Uses glucose to produce colorful 3D images of processes in the human body.

Creates detailed images of organs and tissues by using magnetic fields and radio waves.

When a drug has been used so often, a tolerance is developed. You suffer from withdrawal when you stop using it.

Stimulants (ex: cocaine, caffeine, aderol) speed up the nervous system.

Retrieves chemicals that weren't picked up by their intended neurons.

The psychological and physical inability to stop using a drug or substance.

Right Hemisphere (Two Answers)

Moderately deep sleep. Sleep spindles occur during this stage.

Brief bursts of rapid brain activity.

The latent content of a dream is the underlying meaning.

Information Processing Center - Contains the four lobes

_______ are tranquilizers, and known to be sleep inducing, as well as anxiety reducing. (ex: valum)

Opposite of GABA. Excitatory neurotransmitter, speeds up neurons.

An emotional need for a drug or substance, no underlying physical need.

The manifest content of a dream is the plot, or what is remembered.

Junctions between neurons, through which neurotransmitters flow during neural communication.

Neurotransmitter resulting in a rewarding, feel-good feeling. (Too much = Schizophrenia || Too little = Parkinson's)

Thin extension of neurons that carry nerve impulses away.

Chemical or drug that binds to the receptors in the brain to prevent agonists from having a reaction.

The body's natural pain killers.

__________ are painkillers, and results in "numbness". (ex: percocet, morphine, heroin, oxy)

When someone stops using a drug they go through both psychological and physical feelings of discomfort and distress.

Chemical messengers that transmit impulses (neurological information) from one neuron to another.

Tolerance is when your body is so used to a drug or substance that you need more of it to gain the same effects.

Part of the nervous system that contains only the brain and spinal cord.

The reward pathway of the brain.

Smallest unit of the nervous system.

Theory that dreams are our brains trying to make sense of neuronal firings while we're asleep.

Neurotransmitter involved in mood control. (Too much = anxiety || Too little = depression)
