Shared neural control of attentional shifts and eye movements

Article Abstract:

The build-up cells in the superior colliculus of the brain are responsible for the shifts in attention and the generation of eye movements. The cells increase progressively with an increase in activities for the preparation of saccadic eye movements. The translation of the symbolic cue occurs within the saccadic system. It is then sent to the superior colliculus which prepares for the saccade. The attentional processes are a part of the premotor processing occurring in the brain. Isolated shifts in attention are an indication of artificial separation of a natural linkage.

Effects of nicotine on the nucleus accumbens and similarity to those of addictive drugs

Article Abstract:

The addictive property of nicotine is evident from its metabolic and neurochemical effects in the shell region of the nucleus accumbens. These effects are similar to those of other addictive drugs such as morphine and cocaine. Nicotine increases dopamine release, and glucose metabolism which leads to a positive motivational state, attaching reinforcing properties to nicotine-related stimuli. The results are based on a study of intravenous administration of nicotine in rats.

Neural progenitor cell engraftment corrects lysosomal storage throughout the MPS VII mouse brain

Article Abstract:

The transplantation of beta-glucuronidase expressing neural progenitors into the newborn mice cerebral ventricles reveals that the donor cells are engrafted all over the neuraxis. The various regions of the brain possessed donor-derived cells that are present as normal constituents. The entire neuraxis exhibited the beta-glucuronidase activity.
