Identifying their molecular nature offers great promise to unders

Identifying their molecular nature offers great promise to understand neurovascular disorders and to develop novel neurovascular medicine. Second, the role of pericytes has turned out to be more important than previously recognized. Y-27632 research buy Do pericyte abnormalities causally contribute to neurodegeneration and other types of neurological disorders, and can they be therapeutically targeted? Finally, the brain vasculature is now considered to be a major contributor of the neurogenic stem cell niche. Can this process be exploited for brain repair? Finding

an answer to these and other questions promises to be a scientifically exciting journey with great translational potential.

“Throughout the visual system of vertebrates, neurons are tuned to respond to different features of a visual scene, such as the position, orientation, or direction of motion

of a given object. In the mammalian primary visual cortex, most neurons respond selectively to a preferred orientation of visual stimuli. Some of these neurons are also direction selective, in that they are significantly more activated by a preferred direction of stimulus motion than by any other direction (Hubel, 1959 and Hubel and Wiesel, 1959). Since the first recordings of visual responses in the cat primary visual cortex (Hubel, 1959 and Hubel and Wiesel, 1959), numerous studies have focused on the mechanisms underlying the development of selective properties of visual cortical neurons. These studies were mostly performed in carnivores, such as cats and ferrets, and in primates.
