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