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