Reading mind with ultrasound

Date: 29 March 2021 Tags: Miscellaneous
  • A less-invasive technology called functional ultrasound has now shown the ability to map brain activity even from regions deep within the brain.
  • It produces detailed images of the neural signals that could not be seen with other non-invasive techniques like fMRI (functional magnetic resonance imaging).
  • The device interprets the person’s neural activity and intentions and moves the robotic arm correspondingly.
  • A major limitation for the development of BMIs is that the devices require invasive brain surgery to read out neural activity.
