3 tries left\nwhich of the following is true of macroelectrode recording techniques?\nthey are used to study the functions of single neurons.\nthey are used to map regions of the brain.\nthey are used to study brain waves.\nthey use radioactive energy to map the brain.
Answer
Brief Explanations:
Macroelectrode recording techniques are typically used to record the electrical activity of large - scale neural populations, which is related to studying brain waves. They are not used for single - neuron studies (microelectrodes are more suitable for that), not mainly for mapping brain regions in the way described, and do not use radioactive energy for mapping.
Answer:
They are used to study brain waves.
