DefinitionTerm
Network of neurons in brain stem
Neurotransmitters that bind to own receptors to regulate release of neurotransmitters
The electrical charge of a neuron when it is not active
A principle that states a neuron either fires or it doesn't
When neuron goes back to resting membrane potential; only strong signals can make it fire
Amino acid which is the primary inhibitory signal in the nervous system
Fatty substance which protects the axon
When an enzyme destroys transmitter substance in synaptic cleft
Detects information from physical world and passes it on
Outer layer of brain tissue which forms the surface of the brain
Signals that go from brain to body
A signal which will fire a neuron
In charge of metabolism and genetic material
Toxin that mimics ACh
Monoamine needed for emotional states, impulse control, and dreaming
A rope of neural tissue inside the hollows of vertebrae
Brain structure that associates things with emotions and processes emotional information
Monoamine involved in reward, motivation, and motor control
Lobe almost exclusive for vision
Collects information from thousands of neurons
Peptides involved in natural pain reduction and reward
Release chemicals into the synapse to send to another neuron
Produces myelin
Monoamine known as adrenaline
Houses basic functions: breathing, swallowing, vomiting, urination, orgasm
A small brain structure in the limbic system vital for temperature regulation, emotion, sexual behavior, and motivation
Gateway to the brain which receives almost all incoming sensory information
DefinitionTerm
Process where neurotransmitters return to original vesicles
Brain structure important for formation of certain types of memory
A chemical substance which carries signals across synaptic cleft
Space where axon is exposed; action potentials can move through neuron
Responsible for motor control at junction between nerves and muscles. Involved in dreaming, memory, sleeping and learning
Allows for chemical symbols to pass through neuron
Looks at the transmission of genes from parents to offspring
Lobe which is important for processing auditory information and memories
Directs muscles to contract or relax thus causing movement
Sodium channels become more resistant to sodium ions and the neuron does not fire
Momentary hyperpolarization when sodium ions stop flowing into the neuron
When a neuron fires
A signal which will not fire a neuron
Lobe in charge of sense of touch and spacial layout
Signals that go from body to brain
Largest part of occipital lobe
Region at front of cerebral cortex concerned with planning and movement
A system of subcortical structures important for movement
Part of the brain essential for coordination and balance
Comprised of spinal cord, brain stem, and cerebellum
Specialized protein molecules on neuron
A rush of sodium ions into the neuron causing the neuron to fire
The first part of the neuron to receive signals
Group of single strand amino acids
Monamine important for arousal and vigilance
Looks at overall amount of differences between individuals in a population
Neurons that communicate in short or local distances
