A tight grouping of neurons.
A process in which a neuron is instructed not to transmit information to other neruons.
The number of positive inputs a neruon must receive before it transmits information.
It states that once the threshold for a particular neruon is reached, it will transmit all of its information, no matter how many more positive inputs it receives over the threshold.
An electrchemical ripple that works its way from the cell body to the terminal buttons and terminates in the release of neurotransmitters that will stimulate the next neuron.
A relatively negative state inside a neuron in which the neruon's fluid interior contains a surplus of negatively charged particles.
Nodes of Ranvier
Parts of an axon that are not insulated by myelin.
The area between neurons across which nerve impulses travel.
A narrow space between a transmitting neuron's terminal buttons and a receiving neuron's dendrites.
A neuron that delivers a signal to a synapse.
A neuron that receives a signal form a synapse.
A chemical message created by a synapse from an electric message transmitted by treminal buttons.
A process in which neurotransmitters are released back to a pre-synaptic neuron.
Describes a flexible ability to grow and change.
Connects the spinal nerves to the brain and organizes simple reflexes and rhythmic movements.
Rapid and automatic neuromuscular actions generated in respones to a specific stimulus.
The base of the brain; responsible for survival-oriented function, and basic arousal.
A system in the brain made up of a number of structures that control social and emotional behavior; influences congnitive processes, most notably forms of memory.

A part of the brain that regulates cardiac and respiratory function.
A part of the brain that is involved in sleep, dreaming, left-right body coordination, and arousal.
A part of the brain located just above the brainstem that receives sensory information, processes it, and sends it to the cerebral cortex.
An outer part of the brain that is mainly involved in the coordination of sensory and motor information.
A part of the brain that coordinates muscle movements and maintains equilibrium.
A set of interconnected structures in the brain that help with motor control, cognition, different forms of learning, and emotional processing.
A part of the basal ganglia; involved in control of voluntary movement, and part of the brain's learning and memory system.
A partof the basal ganglia; involved in reinforcement learning.
A part of the basal ganglia; relays information from the caudate and putamen to the thalamus.
A part of the limbic system; involved in fear detection and conditioning.
A part of the brain involved in processing explicit memories, recognizing and recalling long-trem memories, and conditioning.
A small struture in the brain that links the nervous system to the endocrine system.
A part of the brain that is divided into four sections and is involved in various functions such as emotion, response selection, personal oriention, and memory formation and retrieval.
A physiological response to stressors, triggered by the amygdala, in which the body becomes prepared for action.
A large band of axons connecting the two hemispheres of the brain.
Anterior cingulate cortex
An area of te brain that serves as an executive control system that helps control a persons behavior. (pain)
Part of the cingulate cortex; primarily involved in response selection.
Posterior cingulate cortex
Part of the cingulate cortex; primarily involved in personal orientation.
Part if the cingulate cortex; involved in memory formation and retrieval.
Involved in the release of hormones that regulate metabolism, growth, development, tissue function, and mood.
Secretes human growth hormone and influences all other hormone-secreting glands.
A substance that makes up the cerebral cortex; covers the cerebrum and cerebellum.
Bulges in the cerebral cortex.
Grooves in the cerebral cortex.
Consists of myelinated axons that form the connedtions within the brain.
A part of the cerebral cortex that serves basic sensory and motor functions.
A part of the cerebral cortex that helps basic sensory and motor information from a specific lobe integrate with information form the rest of the brain.
Parts of the brain involved in the visual processing; the smallest of the four lobes in the human brain.
Primary visual cortex
A part of the brain that receives input from the eyes and translates that input into what people see.
Parts of the brain involved in auditory processing.
Parts of the brain primarily concerned with bodily sensations.
Primary audutory cortex
A part of the brain involved in the auditory processing.
Primary somatosensory cortex
