Visual object recognition refers to the ability to identify the objects in view based on visual input. One important signature of visual object recognition is "object invariance", or the ability to identify objects across changes in the detailed context in which objects are viewed, including changes in illumination, object pose, and background context.
The grandmother cell (now called Concept Cell), sometimes called the "Jennifer Aniston neuron", is a neuron that represents a specific concept or object. [1] It activates when a person "sees, hears, or otherwise sensibly discriminates [i.e. recognizes]" [ 2 ] a specific entity, such as your grandmother.
The ventral stream, sometimes called the "What Pathway", is associated with form recognition and object representation. It is also associated with storage of long-term memory. The dorsal stream begins with V1, goes through Visual area V2, then to the dorsomedial area (DM/V6) and middle temporal area (MT/V5) and to the posterior parietal cortex.
Lobes in this cortex are more closely associated with memory and in particular autobiographical memory. [15] The temporal lobes are also concerned with recognition memory. This is the capacity to identify an item as one that was recently encountered. [16] Recognition memory is widely viewed as consisting of two components, a familiarity ...
Recognition memory, a subcategory of explicit memory, is the ability to recognize previously encountered events, objects, or people. [1] When the previously experienced event is reexperienced, this environmental content is matched to stored memory representations, eliciting matching signals. [ 2 ]
The researchers found that, much like brain cells, these other types of cells responded to the chemical signals by switching on a gene associated with memory storage.
The visual system is organized hierarchically, with anatomical areas that have specialized functions in visual processing. Low-level visual processing is concerned with determining different types of contrast among images projected onto the retina whereas high-level visual processing refers to the cognitive processes that integrate information from a variety of sources into the visual ...
The findings revealed that there may be binge-drinking related functional alteration in recognition working memory processes. This suggests that impaired prefrontal cortex function may occur at an early age in binge drinkers. Another study conducted in 2004 [27] examined the level of response to alcohol and brain response during visual working ...
