Aparticipant in a study of music perception listens to music with electrodes attached to her scalp while data are collected on the activity of her brain. this technique is

Electroencephalography (EEG)

Explanation:

Electroencephalography is an electro-physiological technique developed in 1924 which detects the electrical activity in the brain by attaching metal discs on the scalp.

The metal discs measure the electrical signals in the form of bolts which gets recorded and sent to the amplifier which sequences the activity and tells the cortical region which got activated.

Thus, EEG is the correct answer.

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
