...solution for many diseases, as stem cell and regenerative biology professor Kevin Eggan said in a talk last night, titled “Using Stem Cells and Reprogramming to Model Neural Degeneration.” For example, he said it is difficult to imagine growing a new forebrain in the case of Alzheimer’s Disease, which is effectively what would need to be done to cure it. Stem cell research can be applied to better understand the biological progression of many more complicated diseases, Eggan said in a Sever Hall presentation. He focused on his own research, examining...
...distracting the brain with reflections of the unconscious) was a pillar of psychiatry. In The Brain as a Dream State Generator: An Activation-Synthesis Hypothesis of the Dream Process, the Harvard pair challenged Freudian theory on virtually every point. They argued that dreams are nonsense created when the forebrain makes "the best of a bad job in producing even partially coherent dream imagery from the relatively noisy signals" sent up to it from the brain stem at the onset of REM. Their paper served to yank dreaming from the realms of the psychological and plonk it in a dreary, physiological...
...subsequent periods of sleep. Neuroimaging has told us a lot about the dreaming-or at least the REM-brain. Those areas that are active include the brain stem (responsible for basic functions like heartbeat regulation), the limbic system (which mediates emotions, learning and memory) and parts of the forebrain involved in processing sensory information. Shut down, meanwhile, are the bits responsible for the most sophisticated mental processes, such as logical and ordered thought. It's a profile that fits neatly with the subjective experience of dreaming: vivid images, strong emotion and snippets of memory, but a shortage of coherence. Rather...
...then ... defeat. Now, with the image of Bush's victory speech seared into Democrats' forebrain, the temptation to abandon all hope is almost overwhelming, especially for those who, right up to the end, refused to entertain the possibility of a second term...
...first attempt to do gene therapy for Alzheimer's, and it took 11 hours to perform. It was designed primarily to determine whether the procedure is safe enough to test further. The goal is to bolster a group of neurons called cholinergic cells located at the base of the forebrain. These brain cells play a critical role in our ability to reason and process information, but they are just one of several kinds of cells that degenerate during the course of the disease...
