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