In the cortex, Generic Priligy there are three basic types of neurons: pyramidal, stellate, fusiform. Pyramidal cells with long axons that enter into other parts of the brain and dendrites covered with numerous spines - synaptic structures through which the nerve cell is in contact with other nerve elements. Spines are extremely sensitive to various factors: hypoxia, asphyxia, and the effect of toxic substances under the influence of which they will atrophy, and thus violated the functional connections.     Stellate cells have short dendrites and axons, their function is to ensure connections between neurons of the cortex.     Spindle-shaped cells form a vertical or horizontal connections of neurons of different layers of the cortex.     Neocortex has a six-layer structure. The buying accutane first layer - molecular OR plexiform contains few cells and nerve fibers are mainly formed by ascending dendrites of pyramidal neurons and fibers nonspecific nuclei of the thalamus, regulating the level of excitability of the cerebral cortex.
