Verified
PET scan and fMRI imaging show that pain stimuli activate which parts of the brain?
A) The primary and secondary somatosensory cortices
B) The primary somatosensory cortex and thalamus
C) The anterior cingulate cortex and the cerebellum
D) Many areas of the brain, including all of these
Somatosensory Cortices
Regions of the brain that process sensory information from various parts of the body, including touch, temperature, and pain.
Anterior Cingulate Cortex
A region of the brain involved in processing emotions, decision-making, empathy, and impulse control.
fMRI Imaging
Functional Magnetic Resonance Imaging, a technique that measures brain activity by detecting changes associated with blood flow.
