The brain is the central organ of stress and adaptation to stress because it perceives and determines what is threatening, as well as the behavioral and physiological responses to the stressor. The adult, as well as developing brain, possess a remarkable ability to show reversible structural and functional plasticity in response to stressful and other(More)
Adolescence is a time of continued brain maturation, particularly in limbic and cortical regions, which undoubtedly plays a role in the physiological and emotional changes coincident with adolescence. An emerging line of research has indicated that stressors experienced during this crucial developmental stage may affect the trajectory of this neural(More)
Nearly 12% of US children are exposed to intense adverse experiences. Research has demonstrated that these experiences can negatively impact adult health, often resulting in psychopathology. Less attention, however, is given to the impact of childhood adverse experiences on childhood health and wellbeing. Using a rodent model of chronic juvenile stress(More)
Early life stress produces long-term alterations in cognition, emotionality, and stress responsiveness. The stress-sensitive hippocampal formation plays a role in producing many of these alterations. We report that adult male rats exposed to early life stress, in the form of maternal separation (MS), exhibit baseline impairment of hippocampal dependent(More)
Three amputation surfaces were formed on the lower arm of a single newt. Growth occurred on all combinations of these surfaces. The proximal surface (the only single surface to form regenerates) produced more regenerates (76% of the cases) than the two more distal surfaces. Blocking the proximal surface with whole skin greatly stimulates the production of(More)
