Abstract The ability of the forebrain to track and integrate respiratory signals, a process known as breathing interoception, is critical for detecting respiratory threats and ensuring survival, yet its neural mechanisms remain largely unknown. Using human intracranial recordings, we identified widespread synchronization between forebrain neural oscillations and breathing rhythms across wakefulness, sleep, and external mechanical ventilation.

Abstract Whether physical navigation shares neural substrates with mental travel in other behaviourally relevant domains is debated. With respect to sound, pure tone working memory in humans elicits hippocampal as well as auditory cortical and inferior frontal activity, and rodent work suggests that hippocampal cells that usually track an animal's physical location can also map to tone frequency when task-relevant.

1 INTRODUCTION Subjective tinnitus, a widespread societal and health issue, is commonly defined as the perception of sound in the absence of an external acoustic stimulus. In one of the most popular models of tinnitus (Jastreboff, 1990), focus was drawn to the role of limbic structures (specifically hippocampus, parahippocampal gyrus [PHG], and amygdala) in tinnitus.
