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