which of the following is true of macroelectrode recording techniques?
they are used to study the functions of single neurons.
they are used to map regions of the brain.
they are used to study brain waves.
they use radioactive energy to map the brain.

Explanation:

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.
