🇮🇳India: 4 hospitalised after fainting at home, diagnosed with COVID.
4 patients have been hospitalised with unusual symptoms in a span of 10 days and have been diagnosed with COVID, leaving doctors stumped and wondering if this is a new symptom of the viral infection.
When the mouse faints, its eyes roll back and most neurons across the brain shut off completely (at yellow line in first figure, shows one example #neuropixels recording). But neurons in the hypothalamic PVZ increased their firing during this time period (first group in the second figure). These neurons were causally implicated: inhibition increased fainting duration while excitation increased arousal.
