I'm trying to figure out the most affordable but reliable set-up to do intracranial EEG recordings to examine sleep in fish, etc. If anyone can recommend amplifier brands/models, software, etc. that would be great! Are there amplifiers that talk directly to a computer to save the data on hard drive or is an interface between amplifier and computer always necessary? This is a new area for me and I don't want to buy equipment I don't need. Thanks!
