R²

A measure used in statistical analysis that assesses how well a model explains and predicts future outcomes.

Cells in the peripheral nervous system that produce the myelin sheath around neuronal axons.

A fatty substance that surrounds the axon of some nerve cells, forming an electrically insulating layer.

Relating to or denoting nerve cells in which adrenaline (epinephrine) or noradrenaline (norepinephrine) acts as a neurotransmitter.

The network of nerve cells and fibers that transmits nerve impulses between parts of the body.

A short-lasting event in which the electrical membrane potential of a cell rapidly rises and falls.

A postsynaptic potential that makes the neuron more likely to fire an action potential.

Sensory receptors that respond to potentially damaging stimuli by sending signals to the spinal cord and brain.

Glial cells in the central nervous system that produce myelin.

A powerful stimulant drug that affects the central nervous system.

Relating to or denoting nerve cells in which acetylcholine acts as a neurotransmitter.

A statistical measure that describes the size and direction of a relationship between two or more variables.

A property which a complex system has, but which the individual members do not have.

Chemical substances that transmit signals across a synapse from one neuron to another.

The cerebral cortex covering the front part of the frontal lobe, implicated in a variety of complex behaviors, including planning, and greatly contributes to personality development.

The process by which a cell transports secretory products through the cytoplasm to the plasma membrane.

The propagation of action potentials along myelinated axons from one node of Ranvier to the next node, increasing the conduction velocity of action potentials.

The part of the nervous system consisting of the brain and spinal cord.

An increase in the membrane potential of a cell, relative to the normal resting potential.
