Mitochondrial Function: The Other Half Of The Anti-Aging Story
Telomere science changed everything we knew about aging. But today, I want to talk to you about the other half of the anti-aging equation.
Regular readers will already know by protecting your telomeres, you can slow — and even reverse — the aging process.
You see, your telomeres are like little countdown clocks that protect the DNA in your cells. They shorten with each cell division. And the shorter they get the faster you develop the signs of aging. So by protecting and nourishing them, you can literally turn back the years.
I was one of the first doctors to put telomere science to the test. And for years, I’ve bee...

Cerebellar contributions to self-motion perception: evidence from patients with congenital cerebellar agenesis - Dahlem K, Valko Y, Schmahmann JD, Lewis RF.
The cerebellum was historically considered a brain region dedicated to motor control but it has become clear that it also contributes to sensory processing, particularly when sensory discrimination is required. Prior work, for example, has demonstrated a c... (Source: SafetyLit)

Proton beam therapy 'effective' and 'causes fewer side effects'
ConclusionThis phase II study looked at the long-term side effects of using proton radiotherapy as part of the treatment of children with medulloblastoma. The treatment was used alongside standard surgical removal and chemotherapy. The current study is reported to be the longest prospective follow-up study available on this treatment for medulloblastoma.Overall, 12% of the study's participants had severe hearing loss three years after proton radiotherapy, and 16% at five years. This was reported by the authors to be less than the equivalent 23 Gy dose of standard (photon) radiotherapy, which was said to cause hearing loss ...

Study links epigenetic processes to the development of the cerebellar circuitry
Researchers have, for the first time, described the pivotal changes responsible for controlling the formation of the part of the brain that allows us to learn and execute complex movements. These changes involve modifications to chromatin, which is DNA packaged with protein. More » (Source: The Rockefeller University Newswire)

Harvard Professor Teaches Class On Zombies
CAMBRIDGE (CBS) – Zombies have taken over the screen and our imagination. Halloween even brings them to the streets.
One man says we can learn things about our minds from the mindless.
Dr. Steven Schlozman is a child psychiatrist and MGH and teaches at Harvard. He has combined his love of the horror genre with medicine for a brainy hobby.
He wrote the “Zombie Autopsies.” He lectures across the country about what we can learn from a zombie brain.

Our elegant brain: Motor learning in the fast lane
To learn new motor skills, neurons within the cerebellum engage in elegant, virtually mathematical, computations to quickly compare expected and actual sensory feedback. They then quickly readjust, changing the strength of connections between other neurons to form new patterns in the brain in order to accomplish the task at hand, researchers report.

Autism, Intervening Prenatally? A Conversation With Neurobiologist Jonathan Delafield-Butt
Jonathan Delafield-Butt is a neurobiologist and developmental psychologist at the University of Strathclyde in Scotland who thinks the current theory of evolution needs to be far more nuanced to include, in particular, how biological form and function are transmitted across generations, as well as psychological aspects like feelings. One of Delafield-Butt's interests is "development of children's agency and its origins evident in intentional movements before birth." Jonathan Delafield-Butt is a Lecturer in Early Years at Strathclyde. His BSc (with honors) is in medical chemistry from the University of Leeds, his MSc in ne...
