(1/2)   019-05-20 > the battelle team, under principal investigator dr. gaurav sharma, aims to develop a minutely invasive interface system that pairs an external transceiver with electromagnetic nanotransducers that are nonsurgically delivered to neurons of interest. the nanotransducers would convert electrical signals from the neurons into magnetic signals that can be recorded and processed by the external transceiver, and vice versa, to enable bidirectional communication. > the carnegie mellon university team, under principal investigator dr. pulkit grover, aims to develop a completely noninvasive device that uses an acousto-optical approach to record from the brain and interfering electrical fields to write to specific neurons. the team will use ultrasound waves to guide light into and out of the brain to detect neural activity. the teams write approach exploits the non-linear response of neurons to electric fields to enable localized stimulation of specific cell types. the johns hopkins university applied physics laboratory team, under principal investigator dr. david blodgett, aims to develop a completely noninvasive, coherent optical system for recording from the brain. the system will directly measure optical path-length changes in neural tissue that correlate with neural activity.
