Cannabis is good for the brain!

In a stunning revelation the Guardian has reported that 'black drug' cannabis may in fact have an undetected virtuous side to it. Quoting a group of German scientists, it said that ‘Cannabis use dramatically improves memory capacity in older brains.’ In the German study, tetrahydrocannabinol (THC), when administered in small doses produced “profound, long-lasting improvement in cognitive performance.” The study implies that controlled use of the drug could ward off degenerative conditions like dementia for…
As baby brains form in the womb something, somewhere goes wrong with their wiring leading to conditions like autism, attention deficit disorder and cerebral palsy. Now, as part of a €15m pan-European project (Developing Human Connectome) scientists at the Imperial College London are tracking down these aberrations by using thousands of high-resolution images of pre-natal babies shot in their wombs…from 22 weeks to the time they are born. This landmark project to map the wiring…

Brain hates dirty money

Money cannot buy happiness. Sure, but only if it is not made the right way! Moral stories you heard from your granny now have scientific legs thanks to the work of a group of researchers at the University College London. Their report says that ill-gotten gains elicit a much weaker response in the brain’s reward system than money made scrupulously. In simpler words, the brain winces at the thought of exploiting others for making money--the…

Now type with your mind not fingers!

In the movie Theory of Everything, a stricken Stephen Hawking, genius scientist and author of the bestselling novel Brief History of Time, struggles with a raft of ungainly gadgets to translate his powerful thoughts into printed words. Now, if Facebook’s audacious scientific project succeeds then Hawking and others like him who suffer from crippling motor neuron diseases may never need any of those contraptions to ‘write’ out their thoughts. The social media major is developing…
In a discovery that promises to enhance our understanding of diseases like dementia and stroke, scientists at the University of Queensland in Australia have tracked down a type of cell that cleans up the brain. The researchers found the cell in zebrafish-- an excellent model for studying human biology partly because they are transparent, which enables scientific investigators to easily study what happens inside their brains using advanced light microscopes. Said Ben Hogan, associate professor,…
Scientists have tracked down mutations in a specific gene factor that predict the speed at which memory will deteriorate in Alzheimer patients. The gene in question codes for a neural growth factor. The report was published in Neurology on May 5. The most common form of dementia, Alzheimer’s is a degenerative disease that leads to steady loss of memory and decline in ability to perform daily activities among older adults. The condition is characterised by…
It is common knowledge that high blood sugar increases the risk of a number of cancers. But glioma or brain cancer may not be one of them a new study by a team of Ohio University researchers suggests. In their report published in the journal Scientific Reports, the researchers lead by co-lead author Judith Schwartzbaum, associate professor of epidemiology at OSU, say that while diabetes increases the risk of colon, breast, and bladder cancers, “malignant…
A new study has confirmed a long held belief: altering the circadian clock adversely affects our body’s response to diet. This latest scientific affirmation has come in a report published by the famed Baylor College of Medicine in an online edition of the American Journal of Obstetrics and Gynaecology. A team of researchers from Baylor arrived at this conclusion based on changes that were evident in the digestive tract of mice whose circadian clock they…
Here is another ‘smart’ reason to eat Omega-3 fats. A recent Harvard study shows that in addition to all their other proven health benefits, these friendly fatty acids help in safeguarding the integrity of the blood-brain barrier, a protective shield that defends the central nervous system from blood-borne bacteria, toxins and other pathogens. A Harvard Medical School team led by professor, Chenghua Gu, reported in the May issue of Neuron that the blood-brain barrier remains…
A multicenter trial looking at whether a single dose of millions of adult, bone-marrow-derived stem cells can aid stroke recovery indicates it's safe and well-tolerated by patients but may not significantly improve their recovery within the first three months, researchers report. However, the trial does provide evidence that giving the therapy early -- within the first 36 hours after stroke symptoms surface -- may enhance physical recovery by reducing destructive inflammation as well as the…
