What Is The Striatum? The striatum, also known as the neostriatum or striate nucleus, is a subcortical part of the forebrain and a critical component of the reward system. It receives glutamatergic and dopaminergic inputs from different sources and serves as the primary input to the basal ganglia system.he striatum is heterogeneous in terms of its component neurons. 1  Spiny projection neurons, commonly referred to as medium spiny neurons, are the principal neurons of the striatum. 2  Cholinergic interneurons release acetylcholine, which has a variety of important effects in the striatum. 3  There are many types of GABAergic interneurons.

Striatum The striatum is a subcortical part of the brain consisting of the caudate nucleus and the putamen. It is part of the basal ganglia. The striatum is best known for its role in the planning and modulation of movement pathways but is also involved in a variety of other cognitive processes involving executive function. number of other brain areas and circuits are also related to reward, including the nucleus accumbens and other frontal areas. The main efferent target of the striatum is the globus pallidus, which is primarily inhibited by GABAergic synapses from the striatum. The main afferent region to the striatum is neocortex.

- A Stina is a predator from the deepest parts of the Argentinian forrests spread out to different countries by sneaking onto airplanes. A Stina is highly fund of alcohol and if it consumes enough it will start a strong mating ritual with the nearast male species. Once the Stina is finished mating it is likely start at sucking the eyeball out of its prey/matingpartners socket.

What is Stroma? Stroma is the thick fluid within the chloroplast. I think you mean 'Stroma'. Stroma can refer to two things in Biology. Stroma is the fluid inside chloroplasts, the site of photosynthesis in all plant cells. It is also, however, the framework (like a skeleton) inside any biological tissue, cell or organ.

The role of the striatum in social behavior The striatum is the input module to the basal ganglia, a neuronal circuit necessary for voluntary movement control (Hikosaka et al., 2000). The striatum is composed of three nuclei: caudate, putamen, and ventral striatum. The latter contains the nucleus accumbens (NAcc). The caudate and putamen/ventral striatum are separated by the internal capsule, a white matter tract between brain cortex and brainstem.

Strata Strata visible in the Grand Canyon. Strata (singular stratum) is a layer. In geology, the term refers to a layer of sedimentary rock that generally has the same sediment (particulates) throughout and normally has other layers above and below it.n such cases the strata form vertically, that is bottom to top, implying succession of time on a global scale in accordance with the vertical sequence of strata. Superposition ignores the general case of sedimentation in moving water and most bodies of water have moving water.

Basal ganglia The major input nucleus of the basal ganglia is the striatum (collectively including the dorsal and ventral divisions), which receives information from almost all areas of the cortex. The dorsal striatum (upper region of the striatum) receives information from areas below the cortex (e.g., the midbrain) via the thalamus.

The Role of the Dorsal Striatum in Reward and Decision-Making What distinguishes the human dorsal striatum from the rest of the basal ganglia is its involvement in action-contingent learning (Delgado et al., 2000, 2005a; Knutson et al., 2001; Haruno et al., 2004; O'Doherty, 2004; Tricomi et al., 2004).

Multiple System Atrophy Striatonigral degeneration refers to a disruption of communication between nerve cells within two structures of the brain involved with movement and balance known as the substantia nigra and the striatum. Olivopontocerebellar atrophy refers to specific structures of the brain known as the olives, pons and cerebellum.

Definitions &Translations Striatum. The striatum, also known as the neostriatum or striate nucleus, is a subcortical part of the forebrain. It is the major input station of the basal ganglia system. The striatum, in turn, gets input from the cerebral cortex. In primates, the striatum is divided by a white matter tract called the internal capsule into two sectors called the caudate nucleus and putamen.

definitions - Striatumreport a problem The ventral striatum is clearly delineated by tracing the subicular (subiculum) territory. This corresponds to the olfactory tubercle and the nucleus accumbens, which is not a nucleus, but is a striatal part made up of striatal elements. The ventral striatum is generally associated with limbic structures, such as the amygdala, hippocampus, midline thalamus, and certain regions of the prefrontal cortex. In addition, the ventral striatum is strongly innervated by dopaminergic fibers from the ventral tegmental area (VTA), known as the mesolimbic dopamine system, and has the highest density of serotonergic inputs in the striatum. In its present connotation, the term “ventral striatum” was introduced in 1975 by Heimer and ...

Stretch marks Stretch marks or striae (singular stria) or striae distensae, as they are called in dermatology, are a form of scarring on the skin with an off-color hue. They are caused by tearing of the dermis, which over time may diminish, but will not disappear completely. Stretch marks are often the result of the rapid stretching of the skin associated with rapid growth or rapid weight changes. Stretch marks in most cases may also be influenced by hormonal changes associated with puberty, pregnancy, bodybuilding, hormone replacement therapy, etc.

- The thalamus (from Greek θάλαμος, chamber) is a midline symmetrical structure of two halves, within the vertebrate brain, situated between the cerebral cortex and the midbrain.oth parts of the thalamus, in the human, are about the size and shape of a walnut. These are about three centimetres in length, at the widest part 2.5 centimetres across and about 2 centimetres in height (comparable to an unshelled walnut, with the nut-shell joining in the horizontal plane).
