Differential effects of naloxone on neuroendocrine responses to fear-related emotional stress.

abstract：:For the vestibulo-ocular reflex (VOR) to function properly, namely to ensure a stable retinal image under all circumstances, it should be able to take into account varying eye positions in the orbit and varying orientations of the head with respect to the axis about which it is rotating. We tested this capability by q...
