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