Prosopagnosia

2024
Prosopagnosia, also known as face blindness, is the inability to recognize faces. In severe cases, individuals with prosopagnosia may not recognize close family members, including parents and spouses, by their faces. For instance, someone with prosopagnosia might walk past their child in a crowd, only realizing their mistake upon noticing their child's distinctive backpack or favorite jacket. Prosopagnosia specifically impairs facial recognition, while the recognition of other objects or...

Electrical Penetration Graph (EPG) is a well-established technique for studying the feeding behavior of stylet-bearing insects. Here we show a new application of EPG as a non-invasive tool for the acquisition of intracellular electrophysiology recordings of sieve elements (SEs), the cells that form the phloem vasculature in plants.

2023
Hyperpolarized 129Xe magnetic resonance imaging (MRI) is a method for studying regionally resolved aspects of pulmonary function. This work presents an end-to-end standardized workflow for hyperpolarized 129Xe MRI of lung ventilation, with specific attention to pulse sequence design, 129Xe dose preparation, scan workflow, and best practices for subject safety monitoring.
FAQs
The central problem lies in integrating individual facial features into a stable representation of identity. Damage affecting face-processing networks, especially regions involving the occipital and temporal lobes, can interrupt this integration. As a result, a person may still receive visual information from a face but fail to connect that information with the identity of someone previously familiar.
Face recognition and object recognition can be affected differently because the condition may selectively disrupt face-processing networks rather than visual processing as a whole. Consequently, a person can retain relatively effective recognition of other objects while struggling with familiar faces. This contrast helps psychologists examine whether the impairment is specific to faces or reflects a broader visual disorder.
It demonstrates that seeing a face, remembering a person, and identifying that person are related but distinguishable processes. A disruption in face-processing networks can interfere with linking perceived facial features to a known identity without necessarily indicating a general memory problem. This dissociation provides psychological evidence for partially separate stages within recognition.
Clinical assessment examines whether the difficulty is focused on recognizing familiar faces or extends to vision, object recognition, or memory more generally. Comparing these abilities helps identify the pattern associated with disrupted face processing. The distinction matters because similar everyday complaints may arise from different neurological problems, and the assessment can support more appropriate compensatory guidance.
Useful alternatives include a person’s voice, clothing, gait, and contextual information. These cues provide identity-relevant evidence when facial information is insufficient or cannot be linked reliably to a familiar person. Applying several nonfacial signals can help compensate for the disrupted recognition process and may guide practical support after brain injury or disease.
The condition offers a way to study how specialized brain networks contribute to face perception and how those networks interact with memory and identity recognition. Clinical observations following brain injury or disease can be compared with preserved object recognition and other abilities. This makes the condition valuable for investigating functional specialization within the occipital and temporal lobes.
