Conditioned reflexes in the aspect of physiology

A conditioned reflex (temporal connection) is an individual reaction acquired during life through learning (as opposed to an unconditioned (innate) reflex). It is produced under certain conditions: the coincidence in time of the unconditioned stimulus and the neutral stimulus (a classic example: the presentation of food with the simultaneous ignition of a light bulb), as a result of which a reaction (for example, salivation) appears after a while to the presentation of only a neutral stimulus.
