title: Conditioning in Fish: Effects of X-irradiation.
abstract: Fish were subjected to different levels of high intensity x-irradiation to ascertain the effects of x-rays on acquisition and retention of conditioning. Lethal dosages were also determined. Light was the conditioned stimulus, and electric shock the unconditioned stimulus. Responses were forward darting and backward swimming movements accompanied by increased gill movement. Acquisition of conditioned responses was suppressed by higher dose levels.
