To perform all these processes generic pristiq 100mg with visa, the brain continuously needs to monitor the external world generic pristiq 100mg overnight delivery, read out important information, input the desired information, retrieve related information from memory, manipulate and integrate all types of information, select the appropriate (motor) response, and then output the information necessary for initiating the response to particular brain areas. It is also needed to suppress unnecessary output to inappropriate brain areas and to inhibit inappropriate actions in order to perform spatially and temporally coordinated actions. It would be too long-winded to go into the details of all these processes and the related concepts here. For instance, many conceptual discussions about the linkage between attention, intention, and preparation within the framework of infor- mation processing operations are presented in the literature. One of the most fascinating processes involved in motor behavior is movement preparation. It is based on central processes responsible for the maximally efficient organization of motor performance. In order for motor performance to be efficiently organized, both contextual and sensory information have to be assembled and integrated to shape the motor output. The notion of uncertainty, which is related to the manipulation of contextual information, is at the core of preparatory processes. The best-suited paradigm for studying such processes is the so-called “preparation paradigm. This picture, modified after the seminal anatomical work of Korbinian Brodmann, which appeared in 1909,5 shows, among others, the location of the primary motor cortex, area 4 (filled circles), just in front of the central sulcus (the curved line between numbers 4 and 1) and the premotor cortex (area 6, empty circles). Furthermore, posterior to the central sulcus, the somatosensory cortex is located (areas 1 and 2, stripes) as well as parietal area 5 (triangles). Neuronal activity presented in this chapter was mainly recorded in the primary motor cortex and the dorsal premotor cortex.
