Recently, i am recording fEPSP from CA1.
I don't understand why we could get the recording. What 's schematic circuit of recording?
I use MED64 to record response. It has 64 channels.
So when i stimulate at one channel. I could record many response from different channels.
But I found that some of them have positive responses, and some of them have negative responses.
How did that happen?
I heard that is kind of source and sink theory.
But I don't understand, could anyone teach me about that detail?
Or tell me in which book could I find the answer.
Thanks very much!
