[12-MAY-25] In the paragraphs below are links to example video and telemetry recordings. The telemetry recordings are in our NDF file format. You can view them directly in the Neuroplayer, which is in turn a component in our open-source data acquisition software. The video recordings are in H264 format, packaged in mp4 containers.

EDF Export Demonstration: A recording to demonstrate the export of voltage, temperature, and activity to European Data Format (EDF). A three-channel transmitter with temperature sensor sits in a beaker of water with its leads in air. We move the beaker around over an Animal Location Tracker (ALT). We record video with an Animal Cage Camera (ACC). We provide the export files with correct headers, and plots from an EDF viewer.

Mouse_Tetanustoxin_1: Mouse EEG following injection of tetanus toxin in the visual cortex, recorded by an A3019A with screw electrodes. Shows bursts of high frequency power in the mouse motor cortex and secondary generalised seizure. One electrode is in the visual cortex, the other in the motor cortex.

Mouse_Pilocarpine_1: Mouse EEG following injection of pilocarpine into the visual cortex, recorded by an A3019A with screw electrodes. Shows evolution of epileptiform activity following pilocarpine injection into the visual cortex. Instrumentation: Subcutaneous Transmitter (SCT), Octal Data Receiver (A3027E). (ION/UCL)
M1279645346: Two minutes of heartbeat and respiration from a rat, recorded by an A3019D with two bare-wire electrodes in the chest cavity. In a sixteen-second interval we see the respiration rhythm as well as the heartbeat spikes. The spectrum shows a peak at 1 Hz is the fundamental frequency of respiration. The decreasing peaks at 2, 3, 4, 5, and 6 Hz are its harmonics. The peak at 7 Hz is the fundamental of the heartbeat. In a two-second interval we see the 7-Hz heartbeat clearly, and its harmonics at 14, 21, 28, and 35 Hz. Instrumentation: Subcutaneous Transmitter (SCT), Data Receiver (A3018D). (CHB/Harvard)
M1300920651: One hour of EEG from several rats after injection of tetanus toxin, recorded by an A3019D with screw electrodes. The characteristics file produced by ECP1.tcl from this recording is M1300920651_ECP1.txt. Instrumentation: Subcutaneous Transmitter (SCT), Data Receiver (A3018D). (ION/UCL)
