Someone who suddenly loses the ability to identify objects by feeling them has probably suffered damage to "parietal lobe" area of the cerebral cortex
Step-by-step explanation:
The mammalian brain is divided into lobes, thus one among the four cerebral cortex' main lobes is the parietal lobe.It is located above the temporal lobe, behind the front lobe and the central sulcus.
At the back side of the brain is the parietal lobe, separated into two hemispheres. This functions in the processing of sensory information about the position of body parts, as well as in the perception of visual information and language and math.
