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