Novel Cross-Species Neurophysiological Assays of Reward and Cognitive Domains

2016-08-05 07:08:22 | BioPortfolio

Summary

The overarching goal of this multi-disciplinary research program is to develop and optimize new cross-species translational assessments of reward and cognition that will not only be assessed in parallel in humans and rats, but also produce neurophysiological and behavioral metrics that can be objectively compared across species. The research will build on prior studies by further developing and optimizing (in Phase 1), then validating via pharmacological challenge (in Phase 2), the following assays in both humans and rats:

1. advanced neurophysiological and computational modeling techniques to record and analyze EEG activity within and across species; and

2. behavioral assessments of reward learning, cognitive control, and cognitive flexibility will be analyzed within and across species.

The second phase of the study will test the translational validity of these assays, by assessing the impact of a targeted drug on task performance and EEG activity in both species.

Description

The overarching goal of this multi-disciplinary research program is to develop and optimize new translational assessments of reward and cognition that will produce neurophysiological and behavioral metrics that enable objective comparison of drug effects.

Phase 1 (2016-2018) will seek to develop and optimize computer-based tasks to measure of reward learning and cognition, to be administered during an EEG examination. Each participant will be asked to come for a single visit to complete a brief psychological assessment (interview and surveys), then perform one of the computer-based tasks while EEG data are collected.

In Phase 2 (2018-2020), a new set of participants will be enrolled for four visits. At the first visit they will have a brief psychological assessment (interview and surveys). They will then be assigned to one of the tasks developed during Phase I, and they will also be assigned to one of the study drugs: amisulpride (a dopamine enhancer), vortioxetine (a serotonin enhancer), or modafinil (a cognitive enhancer). At the second, third, and fourth visit, the subject will be given their drug in one of the three doses: a low dose, a higher dose, and a placebo. They will then perform the assigned task during an EEG exam.
