Indeed, when she was asked to give the direction of the slot, her responses were no better than chance. Yet, when she was asked to place the card into the slot, her success was almost to the level of the controls. This implies that in the event of a ventral stream deficit, the dorsal stream can help with processing of special information to aid movement regardless of object recognition.More specifically, the lateral occipital complex appears to respond to many different types of objects. Prosopagnosia (inability to recognize faces) is due to damage of the fusiform face area (FFA). An area in the fusiform gyrus of the temporal lobe that has been strongly associated with a role in facial recognition. However, this area is not exclusive to faces; recognition of other objects of expertise are also processed in this area. The extrastriate body cortex (EBA) was found to be activated by photographs, silhouettes, or stick drawings of human bodies. The parahippocampal place area (PPA) of the limbic cortex has been found to be activated by the sight of scenes and backgrounds. Cerebral achromatopsia (the inability to discriminate between different hues) is caused by damage to the V8 area of the visual association cortex.The left hemisphere seems to play a critical role in recognizing the meaning of common objects. Diagnosis
Classification
Broadly, visual agnosia is divided into apperceptive and associative visual agnosia.Apperceptive agnosia is failure of object recognition even when the basic visual functions (acuity, color, motion) and other mental processing, such as language and intelligence, are normal.
An abscess of the thymus (also known as "Dubois abscesses") is a condition that is one of many possible causes of cysts in the mediastinum. It can present with chest pain behind the sternum.It can be associated with congenital syphilis.Although the thymus is usually classified with the immune system, thymic diseases are classified with endocrine disorders in ICD-9 and ICD-10.
