Working memory (WM) is the ability to store information for short periods of time and is used to execute tasks
WM has been understood to work via the medial prefrontal cortex (mPFC) and dorsal hippocampus (dHPC), but they do not directly project to each other
The nucleus reuniens of the thalamus (Re) is a “middle man” between the mPFC and dHPC
There are projections between the prelimbic cortex (PrL) and Re that may be used during WM
To test the connection of the PrL to Re, a delayed nonmatch to position (DNMTP) task was performed

The objective of this study was to begin to determine the neurobiological underpinnings of psychosocial stress-induced cocaine seeking. Social defeat stress, achieved using the well-established resident-intruder procedure, is an ecologically-valid psychosocial stressor in rodents that may more closely recapitulate those psychosocial experiences that elicit cocaine craving and relapse in human cocaine users. Our laboratory has developed a model of psychosocial stress-induced relapse in rats in which extinguished cocaine seeking is reinstated by re-exposure to a discrete cue that signals impending social defeat stress. We previously reported that an individual rat’s predilection towards the display of active coping behaviors during prior …

Neural plasticity plays a critical role in mediating short- and long-term brain responses to environmental stimuli. A major effector of plasticity throughout many regions of the brain is stress. Activation of the locus coeruleus (LC) is a critical step in mediating the neuroendocrine and behavioral limbs of the stress response. During stressor exposure, activation of the hypothalamic-pituitary-adrenal axis promotes release of corticotropin-releasing factor in LC, where its signaling promotes a number of physiological and cellular changes. While the acute effects of stress on LC physiology have been described, its long-term effects are less clear. This review will describe how stress …
