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