Sampling the brain: A device by the Mayo Clinic can analyze and detect neurotransmitters locally in the brain. Blue wires link an external monitor (circuit board) to gray connectors, which are in turn linked to neurotransmitter-sensing electrodes (not shown). The device is battery operated (the battery is shown connected to the circuit board) and can transmit the neurochemical information from the electrodes to a remote station for analysis.
