That the brain is a powerful and complex organ is no mystery. But what researchers have begun to discover is that there are select areas of the brain that are so dense in their activity and interconnections that researchers have dubbed them the “rich clubs” of the brain. There are regions of the brain in which connectivity is extraordinarily dense — that’s been known for some time. What the present study set out to do was visualize how these dense regions might be connected to one another, possibly forming an elite network between these distinct and powerful regions of the brain.
They found exactly that: Twelve discrete hubs in the brain were interconnected with one another across hemispheres, forming what the researchers call a “rich club,” distinct from the regular or “lower” network of the brain.
New research provides the first evidence that depression can be treated by only targeting an individual’s style of thinking through repeated mental exercises in an approach called cognitive bias modification. The study suggests an innovative psychological treatment called ‘concreteness training’ can reduce depression in just two months and could work as a self-help therapy for depression in primary care.
People suffering from depression have a tendency towards unhelpful abstract thinking and over-general negative thoughts, such as viewing a single mistake as evidence that they are useless at everything. Concreteness training (CNT) is a novel and unique treatment approach that attempts to directly target this tendency. Repeated practice of CNT exercises can help people to shift their thinking style.
