Summary:Dias et al discuss the study by Folschweiller and Sauer which demonstrated that respiratory-coupled oscillations (RCOs) are associated with opposite emotional states in mice. They implanted tetrode-silicon probe microdrives to record local field potentials and single-unit activity in the medial prefrontal cortex (mPFC) and conducted parallel respiratory recordings to characterize the dynamics of RCOs across three distinct emotional states. Periods in the home cage were used as a neutral state; the tail suspension test was used as a negative state; and reward-seeking and consumption were used as a positive state. They found that the coupling between breathing and mPFC gamma-frequency oscillations was stronger during periods in the home cage than in either the tail suspension test or reward consumption.
