Insomnia, fun fact those of us who have served or are serving in the military have a much higher incidence of sleep problems. So if you are like me and have ever been prescribed something to help you sleep, you know that there are some unwanted side effects. For instance the time I lost memory of a whole day of interacting with people to the ambien I had taken the night before, not fun. Thankfully Danish researchers found that the level of salts in the brain plays a critical role in whether we a........ Read more »

In a new Nature paper, Berkely neuroscientists Alexander G. Huth and colleagues present a 'semantic atlas' of the human brain. Huth et al. have mapped which brain areas respond to words, according to the semantics (meanings) of each word. It turns out that these maps are highly similar across individuals - which could have implications for 'mind reading' technology.
Huth et al. recorded brain activity with fMRI while seven volunteers listened to over two hours of audio narrative (taken fr... Read more »

Whilst the package inserts of the various drugs that modern medicine has at its disposal provides important information on potential mode of action, there is a growing realisation that drugs generally have quite a few more molecular targets than are perhaps listed. Take for example the quite commonly used (in some parts of the world anyway) compound called melatonin that in some instances can provide almost miraculous relief when it comes to sleeping issues under certain circumstances.
