The reward system and respiration-related oscillations. (A) Topography of the projections from the frontal cortex to the striatum. The olfactory tubercle (OT) receives direct projections from the OB and the nucleus accumbens (NAcc) has been shown to be strongly entrained by RR (Karalis and Sirota, 2018). In the prefrontal cortex, the RR power increases from dorsal to ventral (Karalis and Sirota, 2018; Folschweiller and Sauer, 2021). Adapted from Voorn et al. (2004), copyright (2004) Trends in Neurosciences, with permission from Elsevier. (B) Left: Power spectra of the mPFC along the dorsoventral axis, shows an increase in power at the frequency of respiration in the ventral direction. Left: Peak power for each mouse at 4 Hz at the most superficial recording site (light blue) and the deepest recording site (dark blue) of the mPFC.
