TL;DR
Results provide evidence that controllability modulates plasticity at the cellular-neuronal level and exposure to uncontrollable shock massively impaired LTP relative to exposure to the same amount and regime of controllable shock.
Abstract
A group of rats was trained to escape low-intensity shock in a shuttle-box test, while another group of yoked controls could not escape but was exposed to the same amount and regime of shock. After 1 week of training, long-term potentiation (LTP) was measured in vitro in hippocampal slices. Exposure to uncontrollable shock massively impaired LTP relative to exposure to the same amount and regime of controllable shock. These results provide evidence that controllability modulates plasticity at the cellular-neuronal level.

Journal of Comparative and Physiological PsychologyEffects of inescapable shock upon subsequent escape and avoidance responding.
1,184 Citations1967J. Bruce Overmier, Martin E. P. Seligman
Exposure of dogs to inescapable shocks under a variety of conditions reliably interfered with subsequent instrumental escape-avoidance responding in a new situation, indicating that interference is not due to acquisition, during the period of exposure to in unavoidable shocks, of inappropriate, competing instrumental responses.
NatureIntracellular injections of EGTA block induction of hippocampal long-term potentiation
1,109 Citations1983Gary Lynch, John Larson +3 more
It is reported that intracellular injections of the calcium chelator EGTA block the development of LTP and this results strongly suggest that LTP is caused by a modification of the postsynaptic neurone and that its induction depends on the level of free calcium.

Rats received electric shock that was preceded by either a warning signal, a series of signals forming an "external clock," or no signal at all, and subjects which could avoid and/or escape shock developed less ulceration than yoked "helpless" animals which received exactly the same shock but had no control over shock.
