Memory and anxiety-like behavior of rats in the plus-maze discriminative avoidance task: Role of serotonergic transmission in the basolateral amygdala.

Optimal levels of anxiety are critical to memory consolidation, but maladaptive anxiety can disrupt memory acquisition. Serotonergic activity within the amygdala influences both anxiety-like behavior and aversive memory consolidation. To evaluate the effects of serotoninergic manipulations within the basolateral amygdala (BLA) on anxiety-like behavior and aversive memory in rats tested in the plus-maze discriminative avoidance task (PMDAT).

Female Rats Are Resistant to Cognitive, Motor and Dopaminergic Deficits in the Reserpine-Induced Progressive Model of Parkinson's Disease.

Parkinson's disease (PD) is the second most common neurodegenerative disease. The main symptoms are motor signs such as resting tremor and difficulty in initializing movements. Non-motor alterations, such as cognitive deficits, can precede the motor symptoms.

Impaired discriminative avoidance and increased plasma corticosterone levels induced by vaginal lavage procedure in rats.

Historically, females have been neglected in behavioral neuroscience research due to the alleged increased variability caused by hormonal fluctuations. More recently, there has been a tendency to include female subjects in the studies, in a majority of those cases with the condition that the hormonal variation is controlled. In rodent studies, the vaginal lavage procedure is a common method of collecting smears and determining the estrous cycle phase.
