Neuro-synaptic relay
A neuro-synaptic relay was a type of implant that recorded neuroelectric responses in humanoid brains.

In 2374, Luther Sloan implanted a neuro-synaptic relay behind Doctor Julian Bashir's right ear. He later asked Bashir to remove it with an ultrasonic extractor so that he could confirm the doctor's innocence. ()
