35
Q

Hemispheres

A

The two halves of the brain.

47
Q

Manipulation technique

A

A technique in which the structure or function of the brain is altered and the resulting effects on behavior are observed.

48
Q

Measurement technique

A

A technique in which the brain activity of subjects is measured while they are engaged in some behavioral task with the aim of identifying brain areas that might be involved in its performance.
