Article Abstract
Rhythmic neural activity, which coordinates brain regions and neurons to achieve multiple brain functions, is impaired in many diseases. Despite the therapeutic potential of driving brain rhythms, methods to noninvasively target deep brain regions are limited. Accordingly, we recently introduced a noninvasive stimulation approach using flickering lights and sounds ("flicker"). Flicker drives rhythmic activity in deep and superficial brain regions. Gamma flicker spurs immune function, clears pathogens, and rescues memory performance in mice with amyloid pathology. Here, we present substantial improvements to this approach that is flexible, user-friendly, and generalizable across multiple experimental settings and species. We present novel open-source methods for flicker stimulation across rodents and humans. We demonstrate rapid, cross-species induction of rhythmic activity without behavioral confounds in multiple settings from electrophysiology to neuroimaging. This flicker approach provides an exceptional opportunity to discover the therapeutic effects of brain rhythms across scales and species.

Models of memory consolidation propose that newly acquired memory traces undergo reorganisation during sleep. To test this idea, we recorded high-density electroencephalography (EEG) during an evening session of word-image learning followed by immediate (pre-sleep) and delayed (post-sleep) recall. Polysomnography was employed throughout the intervening night, capturing time spent in different sleep stages.

Sleep disorders encompass a range of diseases and symptoms that disrupt individual sleep patterns, degrade sleep quality, and diminish sleep efficiency. Currently, the mechanisms governing sleep regulation and the etiology of sleep disorders remain unclear, leading to clinical treatments that are primarily symptomatic due to the absence of precise intervention methods. Recent studies suggest that glymphatic-meningeal lymphatic route is responsible for the clearance of macromolecular metabolites from the brain, thus playing a pivotal role in maintaining sleep homeostasis and circadian rhythm.

Objective: Upcoming neuroscientific research will require bidirectional and context dependent interaction with nervous tissue. To facilitate the future neuroscientific discoveries we have created HarPULL, a genuinely real-time system for tracking oscillatory brain state.
Approach: The HarPULL technology ensures reliable, accurate and affordable real-time phase and amplitude tracking based on the state-space estimation framework operationalized by Kalman filtering.

Aim: Autoimmune diseases, characterized by the immune system mistakenly attacking the body's own tissues, are a growing global concern, with increasing prevalence. The circadian clock is a fundamental regulator of physiological processes, critically modulating immune functions. This review explores the intricate connections between circadian rhythms and immune responses in autoimmune pathogenesis and how disruptions exacerbate disease.

Glial cells are essential regulators of brain homeostasis by orchestrating neuronal function, metabolism and immune responses. However, much less is known about peripheral glial cells, particularly those in the heart. This review explores the development, types and functions of cardiac glial cells, including Schwann cells, satellite glial cells and recently identified cardiac nexus glia, with some reference to their central nervous system counterparts.
