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