Meanwhile, the feeling of pleasantness associated with affective touch activates the anterior cingulate cortex more than the primary somatosensory cortex. Functional magnetic resonance imaging (fMRI) data shows that increased blood-oxygen-level contrast (BOLD) signal in the anterior cingulate cortex as well as the prefrontal cortex is highly ...

[1] Such vivid tactile sensation of an object that is not present results from the unsuccessful attempt of the brain trying to perceive objects that are novel and that represent unreal situations usually triggered by guilt and fear.

Some medications may cause you to feel odd, including a sensation of a heavy head or fogginess, says Wright. ... This also may be accompanied by a tension headache, which is a squeezing head pain ...
A headset worn at home that zaps the brain with the energy of a 9-volt battery could help relieve symptoms of depression, a new study shows.
S2 is colored green and the insular cortex brown in the top right image (coronal section) of the human brain. S1 is green in the top left, and the supplementary somatosensory area is green in the bottom left. The human secondary somatosensory cortex (S2, SII) is a region of sensory cortex in the parietal operculum on the ceiling of the lateral ...
Babinski's sign in a healthy newborn. The Babinski sign can indicate upper motor neuron lesion constituting damage to the corticospinal tract.Occasionally, a pathological plantar reflex is the first and only indication of a serious disease process and a clearly abnormal plantar reflex often prompts detailed neurological investigations, including CT scanning of the brain or MRI of the spine, as ...
