Physical Exercise Effects on Brain EEG

by William Yates, M.D. in Brain Posts

There are a variety of methods to study the effects on exercise on brain function. Brain imaging techniques such as fMRI provides a new tool to search for regional effects of acute and chronic exercise.Another tool that has received less attention is the electroencephalogram or EEG. One EEG measure of brain function is the individual alpha peak frequency or iAPF.The iAPF is positively correlated with arousal, attention and speed of information processing. Higher iAPF is linked to faster spe........ Read more »

The Palm Tree That Waters and Fertilizes Itself

by Elizabeth Preston in Inkfish



Even the most dismal gardener wouldn't mind taking charge of a plot of Lodoicea maldivica. This palm tree knows how to water itself. It even adds fertilizer. As a result, it rules the forest, turning a bad soil situation into seeds the size of a four-year-old human.

Lodoicea maldivica is commonly called the coco de mer palm. "Commonly" might be the wrong word, though, since the tree grows on exactly two islands in the world, in the Seychelles. It roots itself in soil made from weathered g........ Read more »

I See, Said The Blind Man

by Mark E. Lasbury in The 'Scope

I can’t stand it when I get dust in my eye. Can you imagine having a neural implant in your eye? Star Trek’s Geordi LaForge had implanted electrodes that, along with his visor, let him see. Visual neural prostheses are no longer a thing of science fiction, making the blind see is science fact. The only difference is that he saw in all wavelengths of the electromagnetic spectrum. But there’s no reason we can’t do that as well. ... Read more »

Different mental abilities peak at different times of life, from 18 to 70

by BPS Research Digest in BPS Research Digest

Look at the age at which athletes reach their top performance levels in different sports and it seems there isn't a single time in life at which physical capability peaks. For example, footballers are said to peak at around age 27 while for golfers the peak is likely at least five years later, and for ultra-marathon runners, the peak is later still, in the forties. Put simply, you reach your optimum age for different sporting skills at different ages. According to a new analysis, so it is with b........ Read more »

A Newly Discovered Subset of Microglia and their Possible Importance

by Matthew Zabel in Gliosis







Baalman et al. 2015






A study published in last week's Journal of Neuroscience suggests we may have more than one type of microglial cell in our brains. This paper comes on the heals of a separate study published in Science, which looked at the molecular profiles of all brain cells and noted several subtypes within each class of glial cell. Although the data are not significantly compelling, some people obviously think it is wort........ Read more »

Does watching porn affect your performance in bed?

by Dr. Jekyll in Lunatic Laboratories

Pornography, it’s why google and other search engines have safesearch. It’s all around us and if sales are any indication, it is not going away. There have been lots of claims regarding it, but does a predilection for porn mean bad news in bed? That’s the conclusion of many clinicians and the upshot of anecdotal reports claiming a man’s habit of viewing sex films can lead to problems getting or sustaining an erection, but what does science say?...
