I try to set my system for LFP recordings
right now I just try to reduce the noise to a reasonable amplitude.
I use somnosuite for the isoflurane, and stereotact for the headfix with heated bed and sensor for body temperature
I use the A-M 1800 and Heka 18
Right now I try to minimize the noise as much as possible, and for that I improvised a Faraday cage, until I will make a real one (I have half a cage and I close everything with aluminum foil)
I managed to get the noise to -15-15mV but obviously it's to much for LFP recording
thing is we have no idea how a raw signal looks like, what to expect and what should the noise be
right now I just stick the electrode and the ground in saline, for noise reduction purposes.
If anyone has a raw LFP (extracellular recording) signal and noise that they can share, so I will have a clue where I stand, it will help me a lot
To be specific I work with mice and I want to record from the ventral pallidum
Thank you all in advance!
I am also having the same problem. what kind of electrode you are using to recording?
I also use the same. could not mak any reliable output yet
So, I went in for some more troubleshooting and in the end I found out the the thermal sensor and pad (we have this heating pad that we put on the operation bed to keep the mouse warm) introduced a lot of noise.
Taking that pad out of the cage, I managed to lower the noise to ~0.2mV
How does raw data for LFP looks like?
