Question
Which of the following is true of acute recording studies of rat brain electrical activity?
Such studies are done under anesthesia.
The rat must recover from the anesthesia before the start of recordings.
Acute studies focus on motor function.
Acute studies focus on memory function.
These recordings are subject to movement artifacts.

Explanation / Answer
Anaethetics supress many of the brain centers, and thus EEG (electro encephalogram). To observe the electrical activity of brain, the animal should not under anaethecia. Thus, th correct answer is,
The rat must recover from the anesthesia before the start of recordings.
To assess the memory function, long term studies should be carried out, and motor activity can also be assessed without measuring electrical activity (by measuring the physical activity).
