    Modular Quantum Sensor Detects Brain Activity

    Article obtained from Photonics RSS Feed.

    University of Sussex researchers have built and demonstrated a modular quantum sensor capable of recording brain signals. According to the researchers, their device is the first use a modular quantum sensor in the brain to detect a signal. The device uses ultrasensitive quantum sensors to pick up almost imperceptible magnetic fields within the brain to detect and map neural activity.

    “Our quantum sensor has to be exceptionally sensitive to pick up the magnetic fields in the brain, which are very weak indeed,” said Ph.D. student Thomas Coussens, who built the sensor. “To put it into context, the magnetic field of a brain is a trillion times lower than that of a fridge magnet.”

    The quantum magnetic sensor…
