This reminds me of a talk by two of the Nobel price winners in medicine this year (Moser couple). They, together with O'Keefe, measured brain activity in various parts of the brain. Before computer loggers and visualization was very viable, neuroscientists hooked the sensors up to speakers. So they sat and watched mice move in a maze, and listened to various parts of the brain "fire".
- stinos 12y agoThe listening is still being done today in experiments. An experienced neurophysiologist (in the particular field of single cell recordings) can distinguish the sound of an actual braincell firing, or groups thereof, from all surrounding noise. Which is sometimes more convenient than recording the signal, feeding it into rather complicated template matching algorithms and waiting for results. Especially since braincells might die while being recorded from, so you have to decide quickly.
