“…A closely related cognitive process is spatial or declarative memory formation [10]. Of note, respiratory signals modulate hippocampal sharp-wave ripples [38,43]-a biomarker of memory consolidation [9]-implicating a role of Resp in the underlying processes [18,28]. Importantly, the presence of localized, concurrent ripple oscillations in the parietal cortex was recently observed in rats [39] possibly aiding information transfer from hippocampal to neocortical networks during memory consolidation.…”

Synchronous oscillations are essential for coordinated activity in neuronal networks and, hence, for behavior and cognition. While most network oscillations are generated within the central nervous system, recent evidence shows that rhythmic body processes strongly influence activity patterns throughout the brain. A major factor is respiration (Resp), which entrains multiple brain regions at the mesoscopic (local field potential) and single-cell levels. However, it is largely unknown how such Resp-driven rhythms interact or compete with internal brain oscillations, especially those with similar frequency domains. In mice, Resp and theta (θ) oscillations have overlapping frequencies and co-occur in various brain regions. Here, we investigated the effects of Resp and θ on neuronal discharges in the mouse parietal cortex during four behavioral states which either show prominent θ (REM sleep and active waking (AW)) or lack significant θ (NREM sleep and waking immobility (WI)). We report a pronounced state-dependence of spike modulation by both rhythms. During REM sleep, θ effects on unit discharges dominate, while during AW, Resp has a larger influence, despite the concomitant presence of θ oscillations. In most states, unit modulation by θ or Resp increases with mean firing rate. The preferred timing of Resp-entrained discharges (inspiration versus expiration) varies between states, indicating state-specific and different underlying mechanisms. Our findings show that neurons in an associative cortex area are differentially and state-dependently modulated by two fundamentally different processes: brain-endogenous θ oscillations and rhythmic somatic feedback signals from Resp.

“…It is now clear that respiration organizes network dynamics across many limbic structures (Karalis and Sirota, 2022). Breathing patterns change with a variety of emotions (Homma and Masaoka, 2008), however it was only recently discovered that RROs are a major oscillatory correlate of fear expression in rodents (Tort et al, 2018a;Folschweiller and Sauer, 2021). Importantly, RROs and theta rhythms are dissociable, particularly during fear expression (Nguyen Chi et al, 2016;Tort et al, 2018b;Srikanth et al, 2021).…”

Fear and anxiety-based disorders are highly debilitating and among the most prevalent psychiatric disorders. These disorders are associated with abnormal network oscillations in the brain, yet a comprehensive understanding of the role of network oscillations in the regulation of aversively motivated behavior is lacking. In this review, we examine the oscillatory correlates of fear and anxiety with a particular focus on rhythms in the theta and gamma-range. First, we describe neural oscillations and their link to neural function by detailing the role of well-studied theta and gamma rhythms to spatial and memory functions of the hippocampus. We then describe how theta and gamma oscillations act to synchronize brain structures to guide adaptive fear and anxiety-like behavior. In short, that hippocampal network oscillations act to integrate spatial information with motivationally salient information from the amygdala during states of anxiety before routing this information via theta oscillations to appropriate target regions, such as the prefrontal cortex. Moreover, theta and gamma oscillations develop in the amygdala and neocortical areas during the encoding of fear memories, and interregional synchronization reflects the retrieval of both recent and remotely encoded fear memories. Finally, we argue that the thalamic nucleus reuniens represents a key node synchronizing prefrontal-hippocampal theta dynamics for the retrieval of episodic extinction memories in the hippocampus.

Background: Kapalbhati is a fast pace respiratory exercise or pranayam , which is supposed to be practiced by yogis to clean their brain. Pranayamas are well known to improve heart rate variability (HRV) ultimately leading to better autonomic functions. Other studies have observed the immediate effect of kapalbhati on various neurological (brain and spine) and autonomic functions, but their results are varied and inconclusive. Objective: The aim of this study is to find out the changes in HRV and brain waves during and after practice of kapalbhati as compared with the baseline values of different parameters. Methods: Various parameters were measured at baseline, during and after kapalbhati pranayam with the help of Dinamika HRV-Advanced HRV Test System, Moscow, Russia. Statistical analysis was accomplished employing repeated measures analysis of variance with Bonferroni post-hoc analysis and Holm’s multiple comparisons using the Version 28.0.0.0 of the Statistical Package for the Social Sciences (SPSS) for Windows (190) SPSS Inc., Chicago. Results: We found that during and after kapalbhati , changes in HRV were significant in time and frequency domain showing parasympathetic withdrawal and insignificant changes in brain waves as compared with reference point values. Conclusion: Kapalbhati is initially energizing, cleansing, and heating. There occurs parasympathetic withdrawal and sympathetic activation during pranayama . There is an increase gamma wave activation post pranayama showing control of the default mode network.
