Ingenieure haben den kleinsten implantierbaren – drahtlos betriebenen – Gehirnstimulator entwickelt, der an einem menschlichen Patienten demonstriert wurde. Er könnte die Behandlung von arzneimittelresistenten Depressionen und anderen psychiatrischen oder neurologischen Störungen revolutionieren

> powered wirelessly via an external transmitter and used to stimulate the brain through the dura ⎯ the protective membrane attached to the bottom of the skull.

> The device, known as the Digitally programmable Over-brain Therapeutic (DOT), could revolutionize treatment for drug-resistant depression and other psychiatric or neurological disorders by providing a therapeutic alternative that offers greater patient autonomy and accessibility than current neurostimulation-based therapies and is less invasive than other brain-computer interfaces (BCIs).

> “In this paper we show that our device, **the size of a pea**, can activate the motor cortex, which results in the patient moving their hand,”
