Abstract: A system for precision psychiatry includes a wearable device including a cap and EEG electrodes attached thereto, the cap configured to be placed over a head of a user and including a plurality of first linear actuators configured to expand and contract to increase and decrease a size of the cap, respectively, the EEG electrodes connected to the cap via a plurality of second linear actuators configured to expand and contract to move the EEG electrode toward and away from, respectively, a scalp of the user, a processing device configured to be connected to the EEG electrodes of the wearable device to know the 3-D location of the EEG electrodes and to receive brain activity signals therefrom, the processing device generating a neurofeedback signal based on a detected aberrant brain activity, and a feedback device providing the neurofeedback signal to the user.
