Be mindful, of the benefits of mindfulness:

Mindfulness has gotten a lot of press coverage over the last few years, and may well represent an extremely beneficial, cost effective, long term, low side effect treatment for a whole range of common stress, motivation, focus and affective related disorders. Here is a compilation of a few articles on the subject:



"Although we've known that meditation can reduce anxiety, we hadn't identified the specific brain mechanisms involved in relieving anxiety in healthy individuals,"
For the study, 15 healthy volunteers
[TOOO SMALL!!!!! ] with normal levels of everyday anxiety were recruited for the study. These individuals had no previous meditation experience or anxiety disorders. All subjects participated in four 20-minute classes to learn a technique known as mindfulness meditation. In this form of meditation, people are taught to focus on breath and body sensations and to non-judgmentally evaluate distracting thoughts and emotions… Researchers found that meditation reduced anxiety ratings by as much as 39 percent.

The study revealed that meditation-related anxiety relief is associated with activation of the anterior cingulate cortex and ventromedial prefrontal cortex, areas of the brain involved with executive-level function. During meditation, there was more activity in the ventromedial prefrontal cortex, the area of the brain that controls worrying. In addition, when activity increased in the anterior cingulate cortex -- the area that governs thinking and emotion -- anxiety decreased.”

Mindfulness meditation can increase wellbeing and reduce stress in school children

Mindfulness = a mental training that develops sustained attention that can change the ways people think, act and feel

522 pupils, aged between 12 and 16 years, from 12 secondary schools [took] part in the study. 256 pupils at six of the schools were taught the Mindfulness in Schools Project's curriculum, a nine week introduction to mindfulness designed for the classroom." The other 266 pupils at the other six schools did not receive the mindfulness lessons, and acted as a control group.

Our mindfulness curriculum aims to engage even the most cynical of adolescent audience with the basics of mindfulness. We use striking visuals, film clips and activities to bring it to life without losing the expertise and integrity of classic mindfulness teaching."

All the pupils were followed up after a three month period. The follow-up was timed to coincide with the summer exam period -- which is a potential time of high stress for young people. The researchers found that those children who participated in the mindfulness programme reported fewer depressive symptoms, lower stress and greater wellbeing than the young people in the control group. Encouragingly, around 80% of the young people said they continued using practices taught in MiSP's mindfulness curriculum after completing the nine week programme. Teachers and schools also rated the curriculum as worthwhile and very enjoyable to learn and teach.

We found that those young people who took part in the programme had fewer low-grade depressive symptoms, both immediately after completing the programme and at three-month follow-up. This is potentially a very important finding, given that low-grade depressive symptoms can impair a child's performance at school, and are also a risk factor for developing adolescent and adult depression."

"These findings are likely to be of great interest to our overstretched schools who are trying to find simple, cost effective and engaging ways to promote the resilience of their students -- and of their staff too -- at times when adolescence is becoming increasingly challenging, staff under considerable stress, and schools under a good deal of pressure to deliver on all fronts...The next step is to carry out a randomised controlled trial into the MiSP curriculum, involving more schools, pupils and longer follow-ups."

Genetic basis for dyslexia and language impairment?



Dyslexia and language impairment are common learning disabilities that make reading and verbal language skills difficult. Both disorders have a substantial genetic component, but despite years of study, determining the root cause had been difficult.

In previous studies, Gruen and his team found that dopamine-related genes ANKK1 and DRD2 are involved in language processing. In further non-genetic studies, they found that prenatal exposure to nicotine has a strong negative affect on both reading and language processing. They had also previously found that a gene called DCDC2 was linked to dyslexia.

analyzed data from more than 10,000 children born in 1991-1992 who were part of the Avon Longitudinal Study of Parents and Children (ALSPAC)… They found that some variants of a gene regulator called READ1 (regulatory element associated with dyslexia1) within the DCDC2 gene are associated with problems in reading performance while other variants are strongly associated with problems in verbal language performance… these variants interact with a second dyslexia risk gene called KIAA0319. "When you have risk variants in both READ1 and KIAA0319, it can have a multiplier effect on measures of reading, language, and IQ," he said. "People who have these variants have a substantially increased likelihood of developing dyslexia or language impairment."

We now hope to be able to offer a pre-symptomatic diagnostic panel, so we can identify children at risk before they get into trouble at school. Almost three-quarters of these children will be reading at grade level if they get early intervention, and we know that intervention can have a positive lasting effect."

New augmented reality glasses developed, that allow lecturer to see how students feel about content:



New augmented reality glasses have been developed that allow the lecturer to see, above the students heads, symbols that the students can select, from their mobile phone, as to how confident they feel with the content provided. Thus allowing for greater feedback to the lecturer during the lecture
