Comparative Study
Event-related components of the punishment and reward sensitivity.
The present study investigated the properties of feedback-related negativity (FRN) and P3 component of the event-related potentials (ERPs) and their neural sources localization as neurocognitive correlates of the behavioural inhibition and behavioural activation systems (BIS/BAS). The association between BIS/BAS function and anterior cortical asymmetry was tested. ⋯ Results open up new perspectives for future investigations on the relationship between BIS/BAS measures and ERP components to monetary reward during learning.

To approximate methods for human transcranial magnetic stimulation (TMS) in rats, we tested whether lateralized cortical stimulation resulting in selective activation of one forelimb contralateral to the site of stimulation could be achieved by TMS in the rat. ⋯ These data show that TMS can be used to assess the unilateral excitability of the forelimb descending motor pathway in the rat, and suggest that rat TMS protocols analogous to human TMS may be applied in future translational research.
