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