Rewiring The Brain: Teaching An Old Dog New Tricks
For decades, scientists thought that the adult human brain was static and unchanging. But in the last few decades, we have learned that the adult brain is more dynamic than we ever imagined. In fact, the human brain is malleable and can change in response to new experiences. It is adaptable, like plastic – hence the term “neuroplasticity.”

A new brain imaging study shows for the first time that brain inflammation is significantly elevated – more than 30 per cent higher – in people with obsessive-compulsive disorder (OCD) than in people without the condition.
A research team has studied two structurally-similar proteins in the adult brain and have found that they play distinct roles in the development of dementia.
Neurons found to be abnormal in psychosis play an important role in our ability to distinguish between what is real and what is perceived, researchers say.
A new study sheds light on the neural mechanism behind why some people with autism are unable to make eye contact with others.
While researchers report the risk of developing psychosis from cannabis use is relatively small, those who use the drug and already suffer from schizophrenia may notice their condition worsen.
Finally this week, researchers have discovered a mechanism of glucose sensing by muscles that contribute to the regulation of blood sugar levels in the body.

An international team of researchers has found, for the first time, seven risk genes for insomnia. With this finding the researchers have taken an important step towards the unravelling of the biological mechanisms that cause insomnia. In addition, the finding proves that insomnia is not, as is often claimed, a purely psychological condition.
