Mental process to visually perceive a critical number of facts (the pattern), such as characters, shapes, displays, or designs.
The knowledge or perception that someone or something present has been previously encountered.
The inability to recognize a familiar face or to learn to recognize new faces. This visual agnosia is most often associated with lesions involving the junctional regions between the temporal and occipital lobes. The majority of cases are associated with bilateral lesions, however unilateral damage to the right occipito-temporal cortex has also been associated with this condition.

A perceptual phenomenon used by Gestalt psychologists to demonstrate that events in one part of the perceptual field may affect perception in another part.
The perceiving of attributes, characteristics, and behaviors of one's associates or social groups.
Differential response to different stimuli.
Imaging techniques used to colocalize sites of brain functions or physiological activity with brain structures.
The sensory discrimination of a pattern shape or outline.
Non-invasive method of demonstrating internal anatomy based on the principle that atomic nuclei in a strong magnetic field absorb pulses of radiofrequency energy and emit them as radiowaves which can be reconstructed into computerized images. The concept includes proton spin tomographic techniques.
Facial neoplasms are abnormal growths or tumors that develop in the facial region, which can be benign or malignant, originating from various cell types including epithelial, glandular, connective tissue, and neural crest cells.
Lower lateral part of the cerebral hemisphere responsible for auditory, olfactory, and semantic processing. It is located inferior to the lateral fissure and anterior to the OCCIPITAL LOBE.
Facial dermatoses refers to various skin conditions that affect the face, causing symptoms such as redness, inflammation, papules, pustules, scaling, or pigmentation changes, which can be caused by a range of factors including genetics, infections, allergies, and environmental factors.
Posterior portion of the CEREBRAL HEMISPHERES responsible for processing visual sensory information. It is located posterior to the parieto-occipital sulcus and extends to the preoccipital notch.
A strong emotional feeling of displeasure aroused by being interfered with, injured or threatened.
General or unspecified injuries to the soft tissue or bony portions of the face.
Almond-shaped group of basal nuclei anterior to the INFERIOR HORN OF THE LATERAL VENTRICLE of the TEMPORAL LOBE. The amygdala is part of the limbic system.
I'm sorry for any confusion, but "Famous Persons" is not a term that has a medical definition. It refers to individuals who are widely known and recognized in various fields such as entertainment, politics, sports, science, and arts. If you have any medical or health-related terms you would like me to define, please let me know!

Focusing on certain aspects of current experience to the exclusion of others. It is the act of heeding or taking notice or concentrating.
The facial skeleton, consisting of bones situated between the cranial base and the mandibular region. While some consider the facial bones to comprise the hyoid (HYOID BONE), palatine (HARD PALATE), and zygomatic (ZYGOMA) bones, MANDIBLE, and MAXILLA, others include also the lacrimal and nasal bones, inferior nasal concha, and vomer but exclude the hyoid bone. (Jablonski, Dictionary of Dentistry, 1992, p113)
Awareness of oneself in relation to time, place and person.
The electric response evoked in the cerebral cortex by visual stimulation or stimulation of the visual pathways.
Preparation for electron microscopy of minute replicas of exposed surfaces of the cell which have been ruptured in the frozen state. The specimen is frozen, then cleaved under high vacuum at the same temperature. The exposed surface is shadowed with carbon and platinum and coated with carbon to obtain a carbon replica.
The affective response to an actual current external danger which subsides with the elimination of the threatening condition.
The science dealing with the correlation of the physical characteristics of a stimulus, e.g., frequency or intensity, with the response to the stimulus, in order to assess the psychologic factors involved in the relationship.
Electrical responses recorded from nerve, muscle, SENSORY RECEPTOR, or area of the CENTRAL NERVOUS SYSTEM following stimulation. They range from less than a microvolt to several microvolts. The evoked potential can be auditory (EVOKED POTENTIALS, AUDITORY), somatosensory (EVOKED POTENTIALS, SOMATOSENSORY), visual (EVOKED POTENTIALS, VISUAL), or motor (EVOKED POTENTIALS, MOTOR), or other modalities that have been reported.
A technique of inputting two-dimensional images into a computer and then enhancing or analyzing the imagery into a form that is more useful to the human observer.
