which electrode should i choose?

Post  adamyuan on Thu Mar 08, 2012 11:02 pm

hey, everyone,

i am confused with the choose of the electrode, e.g

should i electrode 26 and 46 are also covered with cells?
or only in the situation 17 and 47, then i can say they are covered with cells?

what i want to aks is, only the cells near the electrode, or also the cells over the track can be considered as the object.

Dear Adam,

You can record all electrodes simultaneously and decide based on the signals which electrodes you include in your analysis.

The tracks are covered by insulator. So only the electrodes will be sensing action potentials from cells on thos electrodes as extracellular field potentials.

As many parameters in biological recordings can be quite variable, I would suggest to simply try which response to stimulation you can evoke.

Please consider increasing cell density, as most electrodes are not covered with cells.

Greetings

Thomas
