Like I said, The frequency of the fastest (in frequency) nerves is about 200 to 300Hz. Which mean 300 up & down per second. So the bitrate is 300bit/sec (or 37.5bytes/second), with all the disadventages of keeping it alive, and the lag it cause due to is organic nature and the chemical way it works (explained in the previous comment).
