Brain imaging studies have implicated an area of the cortex called the TPO, lying at the junction of the temporal, parietal, and occipital lobes, which may be the cause of this condition:

a. Anesthesia

b. Synesthesia

c. Senesthesia

d. Synosthesia

e. Sensorithesia

Synesthesia

Explanation:

Brain imaging is a relatively new discipline and a breakthrough technology within medicine, neuroscience and psychology used for cognitive neuroscience, behavioral conditioning, and brain science. It involves different techniques(PET,MRI,CT, MRS,MRSI, MEG etc) for image the structure, function, or pharmacology of the nervous system and brain.

Brain imaging studies have implicated an area of the cortex called the TPO, lying at the junction of the temporal, parietal, and occipital lobes, which may be the cause of a condition called Synesthesia

Wikipedia describe Synesthesia as a perceptual phenomenon in which stimulation of one sensory or cognitive pathway leads to involuntary experiences in a second sensory or cognitive pathway i.e crossing of senses.For instance, people with synesthesia may see sounds, tastes word or probably feel a sensation on their skin when they smell certain scents.

Synesthesia forms as either grapheme-color (where letters or numbers are perceived as inherently colred) or number form synethesia

Little is known about how synesthesia develop but through brain imaging studies, it has been implicated that an area of the cortex called the TPO which lies at the junction of the temporal,parietal, and occipital lobes causes synesthesia.

search in internet u can get it

i think the answer is gold im not entirely sure
