A new study of fainting reveals essential pathways in the brain.

Key points:

  • Fainting affects up to 40 percent of people due to factors like heat and hunger.

  • A new study reveals a neural pathway controlling fainting, challenging the belief of reduced blood flow.

  • Researchers used RNA sequencing to identify unique neurons linked to the heart and brain.

  • Activation of these neurons induces fainting symptoms, offering insights for potential treatments.
