Dorsal stream Psychology Wiki Fando

The dorsal stream is a pathway for visual information which flows through the visual cortex, the part of the brain which provides visual processing. It is involved in spatial awareness: recognizing where objects are in space. The dorsal stream is one of two main pathways of the visual cortex, the other being the ventral stream Dorsal brainstem syndrome is a rare subset of hypoxic ischemic encephalopathy in neonates limited to the isolated involvement of the brainstem with sparing of the supratentorial brain. Due to its subtle imaging features, it is often undiagnosed Dorsal betyr at noe angår ryggen, eller er i retning av ryggen. Anatomisk brukes ordet også for å betegne håndrygg og fotrygg. Det motsatte er ventral, som angir det som hører til kroppens forside eller bukside. Et eksempel er dorsalfleksjon av foten, som er bøying av foten oppover, mot fotryggen. The dorsal cochlear nucleus (DCN, also known as the tuberculum acusticum), is a cortex-like structure on the dorso-lateral surface of the brainstem.Along with the ventral cochlear nucleus (VCN), it forms the cochlear nucleus (CN), where all auditory nerve fibers from the cochlea form their first synapses

The idea of a division between a dorsal and a ventral visual stream is one of the most basic principles of visual processing in the brain (Milner and Goodale, 1995).The ventral stream originates in primary visual cortex and extends along the ventral surface into the temporal cortex; the dorsal stream also arises in primary visual cortex, but continues along the dorsal surface into parietal cortex Dorsal anterior cingulate cortex (dACC) is a brain region that subserves cognition and motor control, but the mechanisms of these functions remain unknown. Human neuroimaging and monkey electrophysiology studies have provided valuable insights, but it has been difficult to link the two literatures. Based on monkey single-unit recordings, we hypothesized that human dACC is comprised of a. The dorsolateral prefrontal cortex (DLPFC or DL-PFC) is an area in the prefrontal cortex of the brain of humans and other primates. It is one of the most recently derived parts of the human brain. It undergoes a prolonged period of maturation which lasts until adulthood. The DLPFC is not an anatomical structure, but rather a functional one Dorsal: directional term that refers to the back. When used in reference to the nervous system, dorsal refers to the back when discussing the spinal cord.However, above the junction of the midbrain and diencephalon, dorsal refers instead to the upper or superior portion of the brain The two-streams hypothesis is a model of the neural processing of vision as well as hearing. The hypothesis, given its initial characterisation in a paper by David Milner and Melvyn A. Goodale in 1992, argues that humans possess two distinct visual systems. Recently there seems to be evidence of two distinct auditory systems as well. As visual information exits the occipital lobe, and as sound.

Dorsal Cavity Definition. The dorsal cavity, or dorsal body cavity, is a fluid filled space which surrounds the brain and spinal cord of vertebrates. The dorsal cavity is usually considered as two semi-separate spaces, the cranial cavity and the spinal cavity, housing the brain and spinal cord, respectively.However, the fluid in the dorsal cavity connects between the brain and spinal cord, but. Dorsal stream: a pathway that carries visual information from the primary visual cortex to the parietal lobe.According to one widely-accepted hypothesis, the dorsal stream (so named because of the path it takes along the dorsal side of the brain) carries information related to movement and spatial relationships between objects in the visual field. It is sometimes called the where pathway Functions Edit. The anterior cingulate cortex can be divided anatomically based on cognitive (), and emotional components.The dorsal part of the ACC is connected with the prefrontal cortex and parietal cortex as well as the motor system and the frontal eye fields making it a central station for processing top-down and bottom-up stimuli and assigning appropriate control to other areas in the brain

The dorsal root ganglion is a collection of neuronal cell bodies associated with the sensory root of the spinal nerves. These ganglia are considered to be a part of the grey matter of the spinal cord. The dorsal root ganglia are present very close to the spinal cord. The posterior root expands to form the ganglia as soon as it leaves the spinal. The largest connection is from the cortex, in terms of cell axons.Many parts of the neocortex innervate the dorsal striatum. The cortical pyramidal neurons projecting to the striatum are located in layers II-VI, with the most dense projections come from layer V. They end mainly on the dendritic spines of the spiny neurons. They are glutamatergic, exciting striatal neurons Dorsal definition, of, relating to, or situated at the back, or dorsum. See more The main difference between dorsal and ventral is that dorsal refers to the back or upper side of an organism whereas ventral refers to the front or lower side.. These are two anatomical terms used to describe the location of structures of the body in anatomy and embryology. In humans, the dorsal side refers to the posterior side while the ventral side refers to the anterior side of the body The dorsal attention network (DAN) is engaged during externally directed attentional tasks and comprised functionally connected brain regions including visual motion area, frontal eye fields, superior parietal lobule, intraparietal sulcus, and ventral premotor cortex

Dorsal: Relating to the back or posterior of a structure. As opposed to the ventral, or front, of the structure. Some of the dorsal surfaces of the body are the back, buttocks, calves, and the knuckle side of the hand. For a more complete listing of terms used in medicine for spatial orientation, please see the entry to Anatomic Orientation. The dorsal attention network (DAN) is one of two sensory orienting systems in the human brain, the other being the ventral attention network.It is involved in voluntary (top-down) orienting and shows activity increases after presentation of cues indicating where, when, or to what subjects should direct their attention Three directional planes exist in the brain: rostral/caudal, dorsal/ventral, and medial/lateral. When sectioning (cutting) the brain, which planes are visible is determined by the type of section. In the sagittal section (which is made parallel to the midline, dorsal to ventral) the rostral/caudal and dorsal/ventral planes can be seen The dorsal cyst of holoprosencephaly is a large cerebrospinal fluid cavity present in holoprosencephaly that occupies the area above the dorsocaudal aspect of the diencephalon. This communicates directly with the prosencephalic, telencephalic, or diencephalic ventricle. This cavity usually abuts the cranial vault in the midline parieto-occipital area and lies directly on the cerebellum because. SUMMARY: The anatomic extent of brain stem damage may provide information about clinical outcome and prognosis in children with hypoxic-ischemic encephalopathy and oral motor dysfunction.

Medulla oblongata, the lowest part of the brain and the lowest portion of the brainstem. Neurons in the different regions of the medulla oblongata transmit motor and sensory impulses and carry out complex integrative functions, helping regulate processes such as respiration, heart rate, and digestion Similarly, we suggest that integrity of the dorsal language stream should be examined in speech disorders caused by other genes, and associated with acquired neurological disorders. In conclusion, we have identified brain anomalies associated with CAS, in a family for whom the underlying molecular basis has not yet been found The implication of the dorsal stream in manipulating auditory information in working memory has been recently established. However, the oscillatory dynamics within this network and its causal relationship with behavior remain undefined. Using simultaneous MEG/EEG, we show that theta oscillations in There are two radically different views on the functional role of the dorsal visual stream. One considers it as a system involved in space perception. The other is of a system that codes visual information for action organization.

From ventral to dorsal, the brain stem is also divided into three major layers (laminae, lamellae): the basis, the tegmentum, and the tectum. The basis is the most ventral lamina of the brain stem and runs its full length (see Figs. 15-1 and 15-5 ). 7 The basis mesencephali is the portion of midbrain ventral to the substantia nigra (i.e., the paired crura cerebrorum) Focal hyperintensity (FHI) in the dorsal brain stem on T2-weighted images of patients with cerebellopontine angle (CPA) tumor was thought to indicate degeneration of the vestibular nucleus and to.

Dorsal stream (Brain areas involved with consciousness) Even at the very early stage of the retina, an important division arises between two parallel visual streams, the dorsal stream and the ventral stream. The dorsal stream projects to the parietal cortex,. Higher brain centers (voluntary control), systemic receptors, and reflexes modify the medulla's output. However, no truly separate inspiratory and expiratory centers have been identified. The medulla does contain several widely dispersed groups of respiratory-related neurons that form dorsal and ventral respiratory groups. Fig. 9-1
