Stressor controllability and learned helplessness: the roles of the dorsal raphe nucleus, serotonin, and corticotropin-releasing factor.

Maier, Steven F., Watkins, Linda R.·2005·Neuroscience & Biobehavioral Reviews

Abstract

The term 'learned helplessness' refers to a constellation of behavioral changes that follow exposure to stressors that are not controllable by means of behavioral responses, but that fail to occur if the stressor is controllable. This paper discusses the nature of learned helplessness, as well as the role of the dorsal raphe nucleus, serotonin, and corticotropin-releasing hormone in mediating the behavioral effects of uncontrollable stressors. Recent research indicates that (a) uncontrollable stressors sensitize serotonergic neurons in the dorsal raphe, and that a corticotropin-releasing factor-related ligand, acting at the Type II receptor, is essential to this sensitization process, and (b) the consequent exaggerated release of serotonin in response to subsequent input is at least in part responsible for the behavioral changes that occur. Finally, implications for the general role of corticotropin-releasing hormone in stress-related phenomena and for the learned helplessness paradigm as an animal model of either depression or anxiety are discussed.

  • Learned helplessness depends critically on pre- and infralimbic cortex in rats, and is known to be mediated by serotonin.

    “Third, learned helplessness, which can be interpreted in goal-directed terms [17], depends critically on pre- and infralimbic cortex in rats [38], and is known to be mediated by serotonin [39].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
