Yes, though not necessarily in the way that you are meaning – some prosopagnosics will have damage to the area in question, so you could say the activity is lower because there is not much left of it!

What happens if the fusiform face area is damaged?
The hypothesis that the FFA is a face-processing module aligned with previous imaging studies that had also linked face perception to this general area of the brain, as well as with cases of patients who had experienced damage to the FFA and subsequently developed a condition known as prosopagnosia, which involves an …
What is the fusiform face area responsible for?
facial recognition
The fusiform face area (FFA, meaning spindle-shaped face area) is a part of the human visual system (while also activated in people blind from birth) that is specialized for facial recognition. It is located in the inferior temporal cortex (IT), in the fusiform gyrus (Brodmann area 37).
Which part of your brain would be disrupted in you had prosopagnosia face blindness )?
Prosopagnosia is thought to be the result of abnormalities, damage, or impairment in the right fusiform gyrus, a fold in the brain that appears to coordinate the neural systems that control facial perception and memory.
Is prosopagnosia caused by lesions to the fusiform face area?
Prosopagnosia localizes to the fusiform gyrus in the medial temporal lobe and occurs from bilateral lesions or less frequently from unilateral lesions involving the right side alone.
Is the fusiform face area Bilateral?
Specifically, the researchers focused on the face-preferential cortical regions (i.e., the bilateral fusiform face area; [FFA, Kanwisher et al., 1997] and the bilateral occipital area [OFA, Gauthier et al., 2000]).
What is the inability to recognize faces?
Prosopagnosia, also known as face blindness, means you cannot recognise people’s faces. Face blindness often affects people from birth and is usually a problem a person has for most or all of their life. It can have a severe impact on everyday life.
Which hemisphere is responsible for facial recognition?
right hemisphere
A quintessential example of hemispheric specialization in the human brain is that the right hemisphere is specialized for face perception.
What part of the brain is responsible for recognizing faces?
temporal lobe
The temporal lobe of the brain is partly responsible for our ability to recognize faces. Some neurons in the temporal lobe respond to particular features of faces.
What does facial recognition rely on quizlet?
-Face recognition depends on unique cognitive and neural processes.
What does a person with prosopagnosia see?
Face blindness, or prosopagnosia, is a brain disorder. It’s characterized by the inability to recognize or differentiate faces. People with face blindness may struggle to notice differences in faces of strangers. Others may even have a hard time recognizing familiar faces.
Which of the following lesion sites is associated with prosopagnosia?
The brain area usually associated with prosopagnosia is the fusiform gyrus, which activates specifically in response to faces. The functionality of the fusiform gyrus allows most people to recognize faces in more detail than they do similarly complex inanimate objects.
Where is the lesion most often associated with prosopagnosia?
Prosopagnosia can have multiple causes; because this is a disorder of visual processing. Lesions can be further localized to inferior occipital region, fusiform gyrus, and temporal cortex. The most common causes include cerebral infarcts and intracranial hemorrhages in the posterior cerebral circulation.
Is prosopagnosia a specific face?
Prosopagnosia is classically defined as a disorder of visual recognition specific to faces, following brain damage. However, according to a long-standing alternative view, these patients would rather be generally impaired in recognizing objects belonging to visually homogenous categories, including faces.
What agnosia means?
Definition. Agnosia is a rare disorder characterized by an inability to recognize and identify objects or persons.
Is prosopagnosia a visual agnosia?
In some cases, individuals with primary visual agnosia cannot identify familiar people (prosopagnosia). They can see the person clearly and can describe the person (e.g., hair and eye color), but cannot identify the person by name.
What is Apperceptive visual agnosia?
Apperceptive visual agnosia refers to an abnormality in visual perception and discriminative process, despite the absence of elementary visual deficits. These people are unable to recognize objects, draw, or copy a figure. They cannot perceive correct forms of the object, although knowledge of the object is intact.
What causes Apperceptive visual agnosia?
Agnosia is usually caused by lesions on the parietal, temporal, or occipital lobes of the brain. These lobes store semantic information and language. Strokes, head trauma, or encephalitis can cause lesions. Other conditions that damage or impair the brain can also cause agnosia.
Can people with object agnosia recognize faces?
Agnosia does not necessarily impair the recognition of all visual stimuli, but can selectively affect certain categories of percepts (objects, faces, colors, written words, body parts, environmental scenes), leaving others intact. Patients are well aware of their predicament.
What causes Simultagnosia?
Simultanagnosia may result from any etiology that causes damage to these areas (e.g, ischemic, inflammatory, hemorrhagic, infectious, traumatic, neoplastic, neurodegenerative). Simultanagnosia may present as an isolated syndrome or in conjunction with other neurological deficits.
