Cocaine addiction is a chronically relapsing brain disease, but its neural basis is not yet well understood. Clinical reports underscore the possible importance of associative processes for regulating at least some aspects of cocaine addiction. The present study reports the effects of reversible lidocaine-induced inactivation of rostral basolateral amygdala (rBLA) and caudal basolateral amygdal...

Alzheimer's disease (AD) is an age-related neurodegenerative disease. Post-mortem examination and brain imaging studies indicate that neurodegeneration is evident in the hippocampus and amygdala of very early stage AD patients. Exercise training is known to enhance hippocampus- and amygdala-associated neuronal function. Here, we investigated the effects of exercise (running) on the neuronal str...

Cyclic AMP response element binding protein (CREB) plays a critical role in fear memory formation. Here we determined the role of CREB selectively within the amygdala in reconsolidation and extinction of auditory fear. Viral overexpression of the inducible cAMP early repressor (ICER) or the dominant-negative mCREB, specifically within the lateral amygdala disrupted reconsolidation of auditory f...

We investigated the involvement of the hippocampal formation and the amygdala in the acquisition and expression of the amphetamine-produced conditioned place preference (CPP). Animals were conditioned in four sessions that included two pairings of d-amphetamine (2.0 mg/kg, s.c.) with one of two distinct compartments and two pairings of vehicle with the other compartment in a counterbalanced man...

Abstract Background Childhood maltreatment (CM) is a potential risk factor for some neuropsychiatric disorders in adulthood (e.g. depression and anxiety) alters trajectories of brain development. Accumulating evidence suggests that functional connectivity the limbic system, especially amygdala, highly associated with childhood maltreatment, although not all studies have found this. These incons...
