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 ...
Studies in 1985 indicated that cerebrospinal fluid and interstitial fluid may flow along specific anatomical pathways within the brain, with CSF moving into the brain along the outside of blood vessels; such 'paravascular channels' were possibly analogous to peripheral lymph vessels, facilitating the clearance of interstitial wastes from the brain.
Large and diverse labeled image and video dataset Flickr Videos and Images and associated description, titles, tags, and other metadata (such as EXIF and geotags) 100 million Video, Image, Text Video and Image classification 2016 [197] [198] B. Thomee et al. Discrete LIRIS-ACCEDE Short videos annotated for valence and arousal.
Using the interview and different methods of imaging, the experimenters hoped to find links between patterns of brain volume loss and performance in the interview. [24] Through image processing, patterns of significant reduced parenchymal volumes that encompass the frontal and temporal lobes were found. Through comparison to a control group of ...
An example of this would be the map in primary visual cortex (V1). Second-order representations, also known as a field discontinuity map, are maps that are organized such that it appears that a discontinuity has been introduced in either the visual field or the retina. The maps in V2 and other extrastriate cortex are second-order ...
Lung parenchyma showing damage due to large subpleural bullae. Parenchyma (/ p ə ˈ r ɛ ŋ k ɪ m ə /) [1] [2] is the bulk of functional substance in an animal organ or structure such as a tumour. In zoology, it is the tissue that fills the interior of flatworms. In botany, it is some layers in the cross-section of the leaf. [3]
This model was then used to look up 100 one-second video segments, in a database of 18 million seconds of random YouTube videos, matching visual patterns to brain activity recorded when subjects watched a video. These 100 one-second video extracts were then combined into a mash-up image that resembled the video. [144] [145] [146]
A vivid image is one which you have a high potential for retrieving its sensory details. The visuo-spatial sketchpad is responsible for holding onto the visual and spatial qualities of a vivid image in your working memory, and the degree of vividness is directly affected by the limits of the sketchpad.
