There are now a number of published studies that have revealed that the progression of Alzheimer’s-like pathologies can be slowed down by housing mice or rats in enriched (vs impoverished) environments. I’ll discuss this growing body of literature supporting the prophylactic or rejuvenative power of exercising your brain and body (at least if you’re a…
My wife Diane and I visited our friend Mary in the hospital on Friday. Mary had just had her “knee replaced” — which is a rather spectacular modern procedure, unimagined not too many years ago. Another modern, commonplace aspect of this kind of surgery was being “enjoyed” by Mary at her morphine-on-demand dispenser! Her machine…
A couple of weeks ago, Jerry Emmons shared his story with Posit Science. It seems that the 84-year-old was spending much of each day re-living old, painful World War II memories. He had been the only survivor in his crew and the horror was haunting him more and more. “Post-traumatic stress disorder,” said his doctor.…

Led by a great Superintendent…
I just read disturbing comments by a highly respected University of California doc Karen Seal [who screens and treats returning veterans from Iraq or Afghanistan at San Francisco’s famous Ft. Miley Veterans Administration Hospital, one of our premier VA Research Hospitals] about the redeployment of young soldiers treated for PTSD and other neurological and psychatric…
Neil Pearson wrote an inspirational and informative comment from a soldier on the front lines of pain therapy about my last entry [which described another neurological confirmation of an empathetic response actually engaging the pain centers of the brain, when a subject witnessed realistic (fake) videos of inflicted pain]. If pain is an issue for…
In the May issue of the journal Cerebral Cortex, a group from the National Institute for Physiological Sciences in Okazaki, Japan reported interesting results from a study in which “pain centers” in the brain were shown to be activated by WITNESSING pain afflicted to others. If you see someone being poked with a sharp needle…
In Caldwell, Idaho, on the Snake River in Western Idaho, Dr. Carolyn Rees tells us that she was at ground zero during a West Nile Virus epidemic “leaving many people with post-encephalitic brain damage”. A review of the research literature on WNV includes a number of studies now documenting enduring memory and other cognitive losses…
