The device 100 includes a visor 1100 that has an LED display 1110, the LED display 1110 10 including a plurality of LEDs and an LED driver, the LED driver being configured to control each of the LEDs to display a visual stimulus. The device 100 also includes at least one electrode 1210 for measuring electrical potential. The device 100 is configured to be mountable 15 on the head of a patient such that when mounted on the head of a patient the LED display 1110 is positioned before the eyes of a patient and the at least one electrode 1210 is positioned adjacent to the occipital lobe of the patient. The at least one electrode 1210 is 20 configured to detect electrical signals from the occipital lobe of the patient in response to the visual stimulus when the device is mounted on the head of a patient.WO 2018/201190 PCT/AU2018/050402 1/25 C) C) C) mm .................. ................... .................. ......... ................ .................. ....................
