The area of the visual cortex that receives the sensory input from the lateral geniculate nucleus is the primary visual cortex, also known as visual area 1 , Brodmann area 17, or the striate cortex. The extrastriate areas consist of visual areas 2, 3, 4, and 5 (also known as V2, V3, V4, and V5, or Brodmann area 18 and all Brodmann area 19 ).
The visual cortex; The visual association cortex. These are components of the visual pathway, also called the optic pathway, [23] that can be divided into anterior and posterior visual pathways. The anterior visual pathway refers to structures involved in vision before the lateral geniculate nucleus. The posterior visual pathway refers to ...
Within one LGN, the visual information is divided among the various layers as follows: [9] the eye on the same side (the ipsilateral eye) sends information to layers 2, 3 and 5; the eye on the opposite side (the contralateral eye) sends information to layers 1, 4 and 6. This description applies to the LGN of many primates, but not all.
Unimodal association cortex: This area receives input from a single sensory modality. The output from the unimodal cortex is largely to unimodal areas. For example, the visual association cortex in the occipital lobe processes visual information, and the auditory association cortex in the temporal lobe processes auditory information. [4]
Extrastriate cortex, also called visual association cortex is a set of cortical structures, that receive information from striate cortex, as well as each other. [2] Recent descriptions of visual association cortex describe a division into two functional pathways, a ventral and a dorsal pathway.
Vision: The visual area known as V1, striate cortex, or (primary visual cortex, Brodmann area 17) is located on the calcarine sulcus deep within the inside folds of the occipital lobe. Hearing: The primary auditory cortex is located on the transverse gyri that lie on the back of the superior temporal convolution of the temporal lobes.
The visual cortex refers to the primary visual cortex, labeled V1 or Brodmann area 17, as well as the extrastriate visual cortical areas V2-V5. [19] Located in the occipital lobe, V1 acts as the primary relay station for visual input, transmitting information to two primary pathways labeled the dorsal and ventral streams. The dorsal stream ...
Brodmann area 19, or BA 19, is part of the occipital lobe cortex in the human brain.Along with area 18, it comprises the extrastriate (or peristriate) cortex. In humans with normal sight, extrastriate cortex is a visual association area, with feature-extracting, shape recognition, attentional, and multimodal integrating functions.
