Cortical somatosensory modalities (Klingner and Witte 2018)
- stereognosis: the ability to understand or recognize an object by touch; deficit: astereognosis
- graphesthesia: the ability to recognize a number or letter traced on the skin; deficit: agraphesthesia
- two-point discrimination: two stimuli applied at the same time are felt as separate
- somatosensory extinction: inability to perceive two simultaneous somatosensory stimuli
- autotopagnosia: inability of patient to point to a part of the body, despite being able to recognize and name that body part; few reported cases, lesions involving left posterior parietal cortex
