Which brain-scanning technique below is correctly matched with its description?

It is the EEG or the electroencephalogram. It is a test used to discover issues identified with electrical movement of the cerebrum. An EEG tracks and records cerebrum wave designs. Little metal circles with thin wires (cathodes) are put on the scalp, and after that send signs to a PC to record the outcomes.

Atp is is our little "pocket" of energy. of course, if you have too little, then it means you have too little energy, and you'll pass out. the way to not have enough, is to have no energy sources (glucose, fats, proteins). you can't have too many atp molecules. cycles like the krebs cycle produce it, but if you have too much of any substrate (or too little for that matter), the cycle stops and atp is no longer made (it stops until substrate levels are such that the process can go on). in any case, this is unlikely since atp is constantly hydrolyzed and remade, even while you're asleep. you won't have too much. if you have zero, you are dead or dying.
