Agnosia
Agnosia is the inability to process sensory information. Often there is a loss of ability to recognize objects, persons, sounds, shapes, or smells while the specific sense is not defective nor is there any significant memory loss. It is usually associated with brain injury or neurological illness, particularly after damage to the occipitotemporal border, which is part of the ventral stream. Agnosia only affects a single modality, such as vision or hearing. More recently, a top-down interruption is considered to cause the disturbance of handling perceptual information.
Fusiform body area
There is evidence that the FBA plays a critical role in how individuals with Anorexia Nervosa (AN) perceive their own bodies and the bodies of others. In the article Body Image Distortion Reveals Amygdala Activation in Patients with Anorexia Nervosa - a Functional Magnetic Resonance Imaging Study" by Gert Seeger and colleagues found that as well as amygdala activation (the brain's fear network), there was activation in the right gyrus fusiform in anorectic patients, but not healthy age-matched controls. This suggests that due to being overly aware and critical of body forms, increased activation in what we now know as the FBA is to be expected. As this study was conducted before the identification of the FBA, the fusiform gyrus activation can be considered previous evidence for the FBA being involved in body perception.
