free will

the power or capacity of a human being for self-direction. The function of the will is to be inclined or disposed toward an idea or action. The concept of free will thus suggests that inclinations, dispositions, thoughts, and actions are not determined entirely by forces over which people have no independent directing influence. Free will is generally seen as necessary for moral action and responsibility and is implied by much of our everyday experience, in which we are conscious of having the power to do or forbear (see paradox of freedom). However, it has often been dismissed as illusory by advocates of determinism, who hold that all occurrences, including human actions, are predetermined. See also agent; volition.

isoniazid

isoniazid

n. a drug of choice for the treatment of tuberculosis. Use of the drug can cause a form of neuritis by blocking the function of pyridoxine (vitamin B6) in metabolizing glutamic acid to form the neurotransmitter gamma-aminobutyric acid. Isoniazid is structurally related to a known monoamine oxidase inhibitor (MAOI), iproniazid, and was reputed to have some antidepressant activity, although it is not clinically used in this role and is not an MAOI. Also called isonicotinic acid hydrazide (INH).
