Additional research has suggested that the right parahippocampal gyrus in particular has functions beyond the contextualizing of visual background. Tests by a California-based group led by Katherine P. Rankin indicate that the lobe may play a crucial role in identifying social context as well, including paralinguistic elements of verbal ...
The brain pathway that orients visual attention to a stimulus is referred to as the orienting system.There are two main types of visual orientations, covert (exogenous) which occurs when a salient environmental change causes a shift in attention and overt (endogenous) which occurs when the individual makes a conscious decision to orient attention to a stimuli [1] During a covert orientation of ...

A case study conducted on a patient with bilateral lesions involving the posterior visual pathways and effecting the lateral parietal-temporal-occipital cortex struggled with early motion tasks, and yet was able to perceive the biological motion of a point light walker, a higher-order task. This may be due to the fact that area V3B and area KO ...
The visual system is the physiological basis of visual perception (the ability to detect and process light).The system detects, transduces and interprets information concerning light within the visible range to construct an image and build a mental model of the surrounding environment.
ILF supports brain functions concerning the visual modality, including object, face and place processing, reading, lexical and semantic processing, emotion processing, and visual memory. Based on these recent findings ILF can be described as a multi-functional white matter pathway involved in visually guided behavior (See Herbet et al. for ...
The MT pathway is involved in the smooth tracking of objects and travels between the SC pathway and the primary visual cortex. In conjunction with the SC pathway and the MT pathway, the FEF pathway allows the infant to control eye movements as well as visual attention. It also plays a part in sensory processing in the infant.
For example, in the second visual area , the map is divided along an imaginary horizontal line across the visual field, in such a way that the parts of the retina that respond to the upper half of the visual field are represented in cortical tissue that is separated from those parts that respond to the lower half of the visual field.
