culture-free test

an intelligence test designed to eliminate cultural bias completely by constructing questions that contain either no environmental influences or no environmental influences that reflect any specific culture. However, the creation of such a test is probably impossible, and psychometricians instead generally seek to develop culture-fair tests.

end plate

a specialized region of a muscle-cell membrane that faces the terminus of a motor neuron within a neuromuscular junction. The depolarization that is induced in this muscular region when stimulated by a neurotransmitter released from the adjacent motor neuron terminus is called the end-plate potential (EPP). A very small variation in this potential due to the random release of tiny amounts of a neurotransmitter at an axon terminal is called a miniature end-plate potential. Also called motor end plate.
