We have evolved an internal biological clock, called the circadian rhythm, to help our bodies adapt to the daily cycle of day and night (light and dark) as the Earth rotates every 24 hours. The term “circadian” comes from the Latin words for ‘about’ (circa) and ‘a day’ (diem). Circadian Rhythm Basics Our cells contain tiny molecular […]
Neuroplasticity Mechanisms of Working Memory (WM) Training Transfer: How Brain Training Works Brain training neuroplasticity is the ability of the brain to reorganize its structure, function and connections as a result of training. General principles Transfer can occur if the criterion and transfer tasks depend on shared networks. Working memory, attention control and fluid reasoning depend on […]

Scientific interest in brain training designed to maintain or improve cognitive functions in the aging brain has been rapidly increasing over the last decade. Numerous studies have shown that neuroplastic change in brain connectivity and function is considerable up to very old age (1, 2, 3, 4). In this review I will be reviewing the peer-reviewed literature […]
Here I review the latest peer-reviewed studies and meta-analyses that look at the benefits of working memory and executive control brain training for depression and anxiety. For some quick definitions, working memory is our ‘mental workspace’ that stores and processes task-relevant information. It is the interface between the current focus of attention and long-term memories. Executive control is our ability to […]
For some quick definitions, general intelligence (g) is how smart we are, a single factor underlying our general cognitive ability. Working memory is our ‘mental workspace’ that stores and processes task-relevant information. It is the interface between the current focus of attention and long-term memories. interface between the current focus of attention and long-term memories. Executive control is our […]
