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 ...
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 ...
Furthermore, the pattern completion exhibited by place cells is symmetric, because an entire memory can be retrieved from any part of it. For example, in an object-place association memory, spatial context can be used to recall an object and the object can be used to recall the spatial context. [51]
Pandemonium architecture is a theory in cognitive science that describes how visual images are processed by the brain. It has applications in artificial intelligence and pattern recognition. The theory was developed by the artificial intelligence pioneer Oliver Selfridge in 1959. It describes the process of object recognition as the exchange of ...
In a similar way, certain particular patches and regions of the cortex are more involved in face recognition than other object recognition. Some studies tend to show that rather than the uniform global image, some particular features and regions of interest of the objects are key elements when the brain needs to recognise an object in an image.
