1. A mote configured to be implanted within a patient, the mote comprising:
an optical receiver configured to wirelessly receive a first power and data signal in form of near infrared light energy within the patient and convert the near infrared light energy to an electrical signal having a supply voltage;
a control module configured to power devices of the mote by supplying the supply voltage to the devices;
a clock generation circuit configured to lock onto a target clock frequency based on the first power and data signal and generate a plurality of clock signals;
a data recovery circuit configured to set parameters of one or more of the devices based on the first power and data signal and a first one of the plurality of clock signals;
a first amplifier configured to amplify a neuron signal detected via an electrode inserted in tissue of the patient;
a chip identifier module configured to, based on a second one of the plurality of clock signals, generate a recorded data signal, wherein the recorded data signal is generated based on a chip identifier of the mote and the neuron signal; and
a driver configured to transmit the recorded data signal from the mote via a first light emitting diode or a radio frequency transmitter.
