Goodale and Milner [2] amassed an array of anatomical, neuropsychological, electrophysiological, and behavioural evidence for their model. According to their data, the ventral 'perceptual' stream computes a detailed map of the world from visual input, which can then be used for cognitive operations, and the dorsal 'action' stream transforms incoming visual information to the requisite ...
The tongue can divide itself in dorsal and ventral surface. The dorsal surface is a stratified squamous keratinized epithelium, which is characterized by numerous mucosal projections called papillae. [11] The lingual papillae covers the dorsal side of the tongue towards the front of the terminal groove.
If talking about the skull, the dorsal side is the top. [38] The ventral (from Latin venter 'belly') surface refers to the front, or lower side, of an organism. [38] For example, in a fish, the pectoral fins are dorsal to the anal fin, but ventral to the dorsal fin. The terms are used in other contexts; for example dorsal and ventral gun ...
The tongue contains taste receptors, that sends sensory information via action potential to the solitary nucleus. Then, such signal is directed towards the gustatory nucleus, which is located within the Thalamus. [12] Topography on the tongue doesn't determine the arrangement and processing of input within this nucleus.
Interaction between dorsal and ventral attention networks enables dynamic control of attention in relation to top-down goals and bottom-up sensory stimulation. [1]The dorsal attention network (DAN), also known anatomically as the dorsal frontoparietal network (D-FPN), is a large-scale brain network of the human brain that is primarily composed of the intraparietal sulcus (IPS) and frontal eye ...
The dorsal lingual branches of lingual artery consist usually of two or three small branches which arise beneath the hyoglossus. They ascend medially to the back part of the dorsum of the tongue. [5] They supply the mucous membranes, the glossopalatine arch, the tonsil, soft palate, and epiglottis; anastomosing with the vessels of the opposite ...
Dorsal consonants are consonants articulated with the back of the tongue (the dorsum). They include the palatal, velar and, in some cases, alveolo-palatal and uvular consonants. They contrast with coronal consonants, articulated with the flexible front of the tongue, and laryngeal consonants, articulated in the pharyngeal cavity.
Posterior to PV is the secondary somatosensory area (area S2, which must not be confused with "region S2" which designates the entire secondary somatosensory cortex, of which area S2 is a part). Deeper in the lateral sulcus lies the ventral somatosensory (VS) area, whose outer edge adjoins areas PV and S2 and inner edge adjoins the insular cortex .
