Figure Lengend Snippet: Configuration of a high-fidelity signal transmission wireless telemetry. (A) A multi electrode array (middle) is connected to a skull mounted pedestal (left). A removable wireless CerePlex radio transmitter (right) attaches to the pedestal and transmits neural signals to a radio receiver connected to a conventional multichannel recording system. (B) Utah array assembly. (C) The wireless transmission system that includes the transmitter pedestal was implemented to be carried by a monkey. (D) Schematics of the data acquisition system. (E) A detailed block diagram of the transmitter CerePlex digital wireless system.

Article Snippet: The receiver uses the exact same topology found in the transmitter (Atheros chipset, ARM processor, and FPGA) to remove the TCP/IP wrapper from the data, and then converts the data into a format compatible with the Cerebus Digital Hub for fiber optic transmission to the Cerebus Neural Signal Processor.

Techniques: Transmission Assay, Blocking Assay

Figure Lengend Snippet: Wireless transmissions are comparable to wired recordings. Performance of the data transmission system based on a Blackrock neural signal simulator and compares it to that recorded by our system after receiving it wirelessly. (A) Transmitted and received spike trains from an example channel. (B) Example of the transmitted and received local field potentials generated by the simulator. (C) Example of the recorded simulated signal using both wired and wireless setups and performed cluster analysis of spike waveforms. (D) The waveform shapes and (E) resulting principal component clusters from the transmitted and received signals. (F) Performance of the transmission based on the percentage of detected wave forms at 10 m distance between the receiver and transmitter.

Figure Lengend Snippet: Experiments examining changes in dlPFC responses in two conditions: (A) head-fixed and movement-restrained condition (top) and when the animal freely roamed in its cage (bottom). (B) The monkey performed 24 trials per reward type per session (five restrained and five freely moving sessions), and each reward type represented one trial. (C) Plot showing that as expected, the animal consumed the preferred reward more often than the non-preferred reward. (D) We quantified the movement of the animal by video recording the movements of the monkey in the freely moving condition then tracking the movements of the monkey’s head of offline by using the transmitter as the reference point (see section 4). (E) We did not observe a significant difference between the extent of movement associated with the preferred and non-preferred reward types during the reward presentation
