irradiation

• Sustantivo que designa la exposición a radiación o un haz de luz. En fisiología, la propagación de impulsos nerviosos sensoriales en la corteza cerebral; en óptica, el aumento aparente de un objeto brillante sobre un fondo oscuro; en el condicionamiento pavloviano, la evocación de un reflejo condicionado por un estímulo similar pero no idéntico; en medicina, el tratamiento de enfermedades, especialmente cáncer, mediante sustancias radiactivas.

A noun referring to the condition of being exposed to radiation, or a column of light. In physiology, it denotes the spread of sensory neural impulses in the cortex. In optics, it describes the apparent enlargement of a bright object against a dark background. In Pavlovian conditioning, it is the elicitation of a conditioned response by a similar but not identical stimulus. In medicine, it refers to the treatment of disease, especially cancer, by exposure to a radioactive substance.
