PMID-18018699[0] HermesB: a continuous neural recording system for freely behaving primates.
- saved the data to compact flash. could record up to 48 hours continuously.
- recorded from an acceleromter, too - neuron changes were associated with high head accelerations (unsurprisingly).
- also recorded LFP, and were able to tell with some accuracy what behavioral state the monkey was in.
- interfaces to the Utah probe
- not an incredibly small system, judging from the photos.
- 1600maH battery, 19 hour life @ 2/3 recording duty cycle -> current draw is 120mA, or 450mW.
- can only record from two channels at once!
- amplifier gain 610.
- used ARM microcontroller ADUC2106
