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