A study of the feather moss Brachythecium rutabulum records long-term electrical activity in dense mats, uncovering fast, intermediate, and slow spike regimes and evidence of directional signal propagation. While not a human brain, the moss shows a rich electrophysiological repertoire that could underpin information processing and inspire biohybrid sensing applications, challenging the view of moss as a simple organism.
Boston Scientific announced a global restructuring to streamline its supply chain and organization, targeting about $700–$800 million in pre-tax charges with completion by 2029. The plan includes transferring manufacturing lines, severance and other costs, while aiming to save roughly $500 million in gross pre-tax expenses to reinvest in growth; the move follows softer performance in electrophysiology and Watchman, and the company expects headcount reductions but will still hire in growth areas.
PhysMAP is a machine-learning framework that identifies neuron cell types from their electrical signatures in vivo, enabling researchers to map cellular contributions to psychiatric disorders such as schizophrenia and major depressive disorder from seven open datasets without genetic manipulation, with potential to guide targeted therapies.
Researchers have identified specific brain wave patterns in the basal ganglia that correlate with Parkinson's symptoms, potentially enabling more precise and dynamic deep brain stimulation therapies to improve motor control.
Researchers conducted experiments on mice to investigate minute-scale oscillatory sequences in the medial entorhinal cortex (MEC). They performed surgeries to implant microprisms or glass windows for optical access to the MEC and adjacent areas. Two-photon calcium imaging and electrophysiological data were collected, and Neuropixels probes were used for recording neural signals. The mice were trained to run on a wheel under minimal sensory stimulation conditions. The study provides insights into the neural activity patterns in the MEC and their potential role in spatial navigation and memory.
Medtronic has received FDA approval for its PulseSelect Pulsed Field Ablation (PFA) System, making it the first PFA technology to be approved. The system provides a safe and effective treatment for both paroxysmal and persistent atrial fibrillation (AF). It offers differentiated safety features, rapid pulmonary vein isolation, and a seamless transition to PFA in a clinician's workflow. The approval follows the recent European CE Mark of the PulseSelect PFA system. Commercialization is set to begin in early 2024.
