  2. Prosopagnosia - Wikipedia

    en.wikipedia.org/wiki/Prosopagnosia

    The term originally referred to a condition following acute brain damage (acquired prosopagnosia), but a congenital or developmental form of the disorder also exists, with a prevalence of 2.5%. [4] The brain area usually associated with prosopagnosia is the fusiform gyrus, [5] which activates specifically in response to faces. The functionality ...

  3. Face inversion effect - Wikipedia

    en.wikipedia.org/wiki/Face_inversion_effect

    Prosopagnosia is a condition marked by an inability to recognize faces. [26] When those with prosopagnosia view faces, the fusiform gyrus (a facial recognition area of the brain) activates differently to how it would in someone without the condition. [27]

  4. Covert facial recognition - Wikipedia

    en.wikipedia.org/wiki/Covert_Facial_Recognition

    Congenital prosopagnosia is an inability to recognize faces without a history of brain damage; while acquired prosopagnosia is caused by damage to the right occipital-temporal region of the brain. In the 1950s it was theorized that the right cerebral hemisphere was involved in facial recognition and in the 1960s this theory was supported by ...

  5. Visual agnosia - Wikipedia

    en.wikipedia.org/wiki/Visual_agnosia

    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. [6] However, this area is not exclusive to faces; recognition of other objects of expertise are also processed in this area.

  6. Associative visual agnosia - Wikipedia

    en.wikipedia.org/wiki/Associative_visual_agnosia

    Agnosias are sensory modality specific, usually classified as visual, auditory, or tactile. [2] [3] Associative visual agnosia refers to a subtype of visual agnosia, which was labeled by Lissauer (1890), as an inability to connect the visual percept (mental representation of something being perceived through the senses) with its related semantic information stored in memory, such as, its name ...

  7. Object recognition (cognitive science) - Wikipedia

    en.wikipedia.org/wiki/Object_recognition...

    The brain region that specifies in facial recognition is the fusiform face area. Prosopagnosia can also be divided into apperceptive and associative subtypes. Recognition of individual chairs, cars, animals can also be impaired; therefore, these object share similar perceptual features with the face that are recognized in the fusiform face area ...

  8. Topographical disorientation - Wikipedia

    en.wikipedia.org/wiki/Topographical_disorientation

    Topographical disorientation is the inability to orient oneself in one's surroundings, sometimes as a result of focal brain damage. [1] This disability may result from the inability to make use of selective spatial information (e.g., environmental landmarks) or to orient by means of specific cognitive strategies such as the ability to form a mental representation of the environment, also known ...

  9. Apperceptive agnosia - Wikipedia

    en.wikipedia.org/wiki/Apperceptive_agnosia

    Brain damage leads to apperceptive agnosia because there is damage to a particular semantic category. [citation needed] Another theory, referred to as functional specialization, states that individual parts of the brain specialize in different tasks. According to this theory, if an area of the brain is damaged, the function that the area is ...
