The role of the striatum in social behavior Social contact and striatal function. The striatum is involved in other social behaviors besides social action, social reward and reward inequity. Social isolation and social defeat compromise the normal function of the striatum. These effects highlight the interplay between normal social contact and striatal function. Social isolation has long-lasting effects in behavior, neuronal anatomy and neurochemistry.

Nucleus accumbens The nucleus accumbens and the olfactory tubercle collectively form the ventral striatum, which is part of the basal ganglia. The nucleus accumbens can be divided into two structures -- the nucleus accumbens core and the nucleus accumbens shell. These structures have different morphology and function.he principal neuronal cell type found in the nucleus accumbens is the medium spiny neuron. The neurotransmitter produced by these neurons is gamma-aminobutyric acid (GABA), one of the main inhibitory neurotransmitters of the central nervous system.

Mechanisms Controlling the Function and Life Span of the Corpus Luteum The primary function of the corpus luteum is secretion of the hormone progesterone, which is required for maintenance of normal pregnancy in mammals. The corpus luteum develops from residual follicular granulosal and thecal cells after ovulation. Luteinizing hormone (LH) from the anterior pituitary is important for normal development and function of the corpus luteum in most mammals, although growth hormone, prolactin, and estradiol also play a role in several species.

- An important pathway in the modulation of the direct and indirect pathways is the dopaminergic, nigrostriatal projection from the substantia nigra pars compacta to the striatum (Figure 4.5). Direct pathway striatal neurons have D1 dopamine receptors, which depolarize the cell in response to dopamine.. The net effect of excitation of the direct pathway is to inhibit cortex. B. Dopaminergic neurons of the substantia nigra signal unexpected reward or unexpected absence of reward. C. The basal ganglia have both motor and cognitive functions.

Nutrient Absorption and Utilization in Ruminants Continuous removal of VFA from the rumen is important not only for distribution, but to prevent excessive and damaging drops in pH of rumen fluid. The rumen is lined with stratified squamous epithelium similar to skin, which is generally not noted for efficient absorption. Nonetheless, this squamous epithelium has a structure which functions similarly to the columnar epithelium in the small gut and performs efficient absorption of VFA, as well as lactic acid, electrolytes and water.

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.

What is the function of the stomata? Stomata are tiny openings or pores in plant tissue that allow for gas exchange. Stomata are typically found in plant leaves but can also be found in some stems. Specialized cells known as guard cells surround stomata and function to open and close stomatal pores. The two main functions of stomata are to allow for the uptake of carbon dioxide and to limit the loss of water due to evaporation. In many plants, stomata remain open during the day and closed at night.
