Visual processing - Wikipedia
Visual processing is a term that refers to the brain's ability to use and interpret visual information from the world. The process of converting light energy into a meaningful image is a complex process that is facilitated by numerous brain structures and higher level cognitive processes.

Most researchers believe that visual processing in the cortex occurs through two distinct 'streams' of information. One stream, sometimes called the What Pathway (purple in the image below), is involved in recognising and identifying objects.
Visuospatial processing: A review from basic to current concepts
2014年3月20日 · Visuospatial processing is a fundamental aspect in human cognition, belonging to a complex and intricate network. It is, in other words, one of the building blocks of an individual's identity and behavior. Objective.
30 Visual System: Central Processing - Michigan State University
Pathway to Brain. Visual information from each eye leaves the retina via the ganglion cell axons at the optic disc, creating the optic nerve. The optic nerve, or cranial nerve II, exits the posterior end of the eyeball, and travels posteriorly along the ventral surface of the brain.
The human imagination: the cognitive neuroscience of visual …
2019年8月5日 · With methodological constraints now overcome, research has shown that visual imagery involves a network of brain areas from the frontal cortex to sensory areas, overlapping with the default...
Perceptual and conceptual processing of visual objects across …
2019年9月24日 · Here, we (1) characterize visual and semantic processes involved in object processing across the adult lifespan, (2) ask if differences in visual processing impact semantics, and (3)...
Human Attention and Visual Cognition: Introduction - PMC
2022年11月28日 · In a world that is increasingly fast and complex, the human ability to rapidly perceive, comprehend, and act on visual information is extremely important. Visual Cognition is the study of these processes. Additionally, given the complexity of stimulus information, prioritization and selection—processes of attention—are central to visual ...
A new neural framework for visuospatial processing - Nature
2011年3月18日 · The division of cortical visual processing into distinct dorsal and ventral streams is a key framework that has guided visual neuroscience. The characterization of the ventral stream as a...
Cortical Processing of Visual Signals | SpringerLink
2022年10月18日 · This chapter describes how visual information is processed in the cerebral cortex. Major events that precede cortical processing include (1) phototransduction by retinal photoreceptors, (2) the establishment of On and Off pathways and center/surround receptive...
Vision: Central Processing – Foundations of Neuroscience
Key Takeaways. Test Yourself. Video Lecture. Visual Fields. Before learning the pathway that visual information takes from the retina to the cortex, it is necessary to understand how the retina views the world around us. The full visual field includes everything we can see without moving our head or eyes. Figure 22.1.
