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