How everyday sounds can trigger strong emotions: ASMR, misophonia and the feeling of wellbeing.

We propose that synesthetic cross-activation between the primary auditory cortex and the anatomically adjacent insula may help explain two puzzling conditions-autonomous sensory meridian response (ASMR) and misophonia-in which quotidian sounds involuntarily trigger strong emotional responses. In ASMR the sounds engender relaxation, while in misophonia they trigger an aversive response. The insula both plays an important role in autonomic nervous system control and integrates multiple interoceptive maps representing the physiological state of the body to substantiate a dynamic representation of emotional wellbeing.

Anti-diabetic effect of vestibular stimulation is mediated via AMP-activated protein kinase.

There is abundant animal evidence that vestibular stimulation, particularly of the otolith organs, can trigger a shift in body mass composition towards a leaner physique. One way of non-invasively stimulating the otolith organs is via a small electrical current applied to the skin behind the ears. This technique is called vestibular nerve stimulation, or VeNS, and is believed to have a good safety profile.

The influence of vestibular stimulation on metabolism and body composition.

Obesity, diabetes and metabolic disease represent an ongoing and rapidly worsening public health issue in both the developed, and much of the developing world. Although there are many factors that influence fat storage, it has been clearly demonstrated that the homeostatic cornerstone of metabolism lies within the hypothalamus. Moreover, neuronal damage to vital areas of the hypothalamus can drive reregulation or dysregulation of endocrine function, energy expenditure and appetite, thereby promoting a shift in overall metabolic function towards a state of obesity.

Can Vestibular Stimulation be Used to Treat Obesity?: Vestibular stimulation targeting the otoliths could rebalance energy homeostasis to trigger a leaner body habitus and thus treat metabolic syndrome.

It is hypothesized that repeated, non-invasive stimulation of the vestibular (balance) system, via a small electrical current to the skin behind the ears, will cause the brain centers that control energy homeostasis to shift the body toward a leaner physique. This is because these centers integrate multiple inputs to, in effect, fix a set-point for body fat, which though difficult to alter is not immutable. They will interpret repeated stimulation of the parts of the vestibular system that detect acceleration as a state of chronic activity.

Is HealthPathways effective? An online survey of hospital clinicians, general practitioners and practice nurses.

Aim: An online survey was used to determine the perceptions of healthcare professionals in Canterbury on HealthPathways, a website that provides clinical and referral information for general practice teams, relevant to locally available health services and resources.

Method: The survey questionnaire included questions on the effectiveness and ease-of-use of the website, computer literacy and use of online clinical guidance systems. Differences in the responses between work groups were analysed using the Mann-Whitney test.
