The information-processing characteristics of time estimation have not been well-documented. This research investigated explicit time estimation to test whether (1) it can occur "automatically" and (2) the cognitive function generally known as "working memory" predicts accuracy of time estimation. Data on two tasks requiring explicit time judgement (time(More)
This research study addresses the question: does the neural circuit implementing a motor task undergo change as a function of even limited practice? To detect potential neural changes associated with limited practice we compared brain activation at the early and late stages of motor performance on a simple task over one relatively brief session.(More)
In the present study we assessed alterations in cognitive functions in a chronic mild stress (CMS) rat model of depression. Cognitive functions were assessed in two different tasks applying the translational operant platform touchscreen technology; the visual discrimination/acquisition task was used to assess the ability to perceive and distinguish visual(More)
