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