Physical Fitness May Slow Alzheimer's

(NEW YORK) — Getting a lot of exercise may help slow brain shrinkage in people with early Alzheimer's disease, a preliminary study suggests. Analysis found that participants who were more physically fit had less brain shrinkage than less-fit participants. However, they didn't do significantly better on tests for mental performance.

Robot with a Biological Brain: new research provides insights into how the brain works

(PhysOrg.com) -- A multidisciplinary team at the University of Reading has developed a robot which is controlled by a biological brain formed from cultured neurons. This cutting edge research is the first step to examine how memories manifest themselves in the brain, and how a brain stores specific pieces of data. The key aim is that eventually this will lead to a better understanding of development and of diseases and disorders which affect the brain such as Alzheimer's Disease, Parkinson's Disease, stroke and brain injury.

Crossing the blood-brain barrier with nanotechnology

(Nanowerk Spotlight) The challenge in treating most brain disorders is overcoming the difficulty of delivering therapeutic agents to specific regions of the brain by crossing the blood-brain barrier (BBB). This barrier – a tight seal of endothelial cells that lines the blood vessels in the brain – is a physiological checkpoint that selectively allows the entry of certain molecules from blood circulation into the brain. The problem for scientists is that the BBB does not differentiate what it keeps out. BBB strictly limits transport into the brain through both physical (tight junctions) and metabolic (enzymes) barriers. With very few exceptions, only nonionic and low molecular weight molecules soluble in fat clear the BBB. For instance, alcohol, caffeine, nicotine and antidepressants meet these criteria.

Physical Frailty May Be Linked To Alzheimer's Disease

Physical frailty, which is common in older persons, may be related to Alzheimer's disease pathology, according to a study published in the August 12, 2008, issue of Neurology®, the medical journal of the American Academy of Neurology.

Rat's Brain Powers Robot

New Scientist reports on a cool, if somewhat creepy development in robotics -- scientists have used bits from a rat's brain to control a robot. The 'why' behind such a Frankenstein is to learn more about how a brain works: by studying the rat brain's reponses to controlled stimulus, the scientists hope to learn more about the internal workings of a brain, which will go a long way to understand the nature of human brain disorders such as Alzheimer's.

Robot with a biological brain

University of Reading scientists have developed a robot controlled by a biological brain formed from cultured neurons. And this is a world’s premiere. Other research teams have tried to control robots with ‘brains,’ but there was always a computer in the loop. This new project is the first one to examine ‘how memories manifest themselves in the brain, and how a brain stores specific pieces of data.’ As life expectancy is increasing in most countries, this new research could provide insights into how the brain works and help aging people. In fact, the main goal of this project is to understand better the development of diseases and disorders which affect the brain such as Alzheimer or Parkinson diseases. It’s interesting to note that this project is being led by Professor Kevin Warwick, who became famous in 1998 when a silicon

Quantum rods probe blood-brain barrier

(Nanowerk News) One of the chief difficulties in treating brain tumors involves getting potential tumor-killing drugs across the blood-brain barrier and into the brain. Now, researchers from a NCI Cancer Nanotechnology Platform Partnership at the University of Buffalo have used targeted quantum rods both to breach the blood-brain barrier and to study how such constructs move across this largely impermeable barrier. Paras Prasad, Ph.D., principal investigator of the SUNY-Buffalo Platform Partnership, led the research team that published results in the journal Bioconjugate Chemistry ("Bioconjugated Quantum Rods as Targeted Probes for Efficient Transmigration Across an in Vitro Blood-Brain Barrier").

Exercise Might Slow Brain Shrinkage in Alzheimer's Patients

(HealthDay News) -- Men and women with early-stage Alzheimer's disease who were more physically fit also had larger brains compared to their counterparts in less stellar shape.

New Map IDs the Core of the Human Brain

gerald626 writes "An international team of researchers has created the first complete high-resolution map of how millions of neural fibers in the human cerebral cortex — the outer layer of the brain responsible for higher level thinking — connect and communicate. Their groundbreaking work identified a single network core, or hub, that may be key to the workings of both hemispheres of the brain. So basically our brain is a network connected to a hub. I wonder if I can get an upgrade to a GigE switch?"
