Liking for sprouts may be partly genetic

tasty_broccoli.jpgNature is reporting that a gene which is involved in a receptor for bitter tastes can predict people’s liking for vegetables such as broccoli and sprouts.

It has been proposed that humans are particularly sensitive to bitterness as natural poisons often taste bitter.

Certain versions of this gene may make us especially sensitive, however. So sensitive, perhaps, that we dislike foods that are perfectly safe but have a bitter element.

There’s more information in a over at Eureka Alert and the original study is published in the journal Current Biology.

Bipolar disorder on the BBC

stephen_fry_bbc.jpgThe BBC has a focus on bipolar disorder over the next few weeks with a TV documentary hosted by Stephen Fry investigating the condition, and a special edition of BBC Radio 4’s Case Notes on the disorder.

We reported earlier this year that Stephen Fry, diagnosed with bipolar himself, visited Cardiff University’s neuropsychiatric genetics unit to film parts of a documentary.

The first part of the documentary was on last night (I missed it I’m afraid and am currently searching bittorrent trackers for a copy) and the next is on BBC2 next Tuesday.

However, the BBC has a webpage with information about the documentary and the condition, including video clips which are available online.

In the documentary, Fry discusses his own experiences, as well as interviewing people like Carrie Fisher, Robbbie Williams and Tony Slattery about their lives with unpredictable thoughts and moods.

The documentary also tackles the psychology and neuroscience of the condition, with the help of researchers who are attempting to make sense of how this complex condition starts, and impacts upon affected individuals.

BBC Radio 4’s Case Notes also discusses bipolar in detail, including the best current treatments and ways of coping.

NYT on killing of Dr Wayne Fenton

wayne_fenton.jpgThe New York Times has an article on the recent tragic death of psychiatrist Dr Wayne Fenton, a respected and admired schizophrenia specialist who seems to have been killed by a patient.

The killing has highlighted the debate about violence and schizophrenia once again.

Violence is rare in people with schizophrenia. In fact, people with schizophrenia are much more likely to be victims of violence than violent themselves.

However, active psychosis is associated with a slightly increased chance of violence in some people, and some have argued that this is a reason for forcibly medicating people with schizophrenia if they refuse treatment.

In contrast, others argue that forcibly medicating anyone is an abuse of the person’s civil liberties.

In most jurisdictions, mental illness is the only type of illness is which a patient’s refusal of treatment can be overruled. For any other type of illness, this decision is typically respected and protected by law.

Interestingly, the risk of violence in schizophrenia is comparable to the risk of violence with alcohol use in adolescents.

Nevertheless, the media tends to focus on violence and schizophrenia, giving a skewed idea of the risks and ignoring more common and less newsworthy stories such as ‘drunk youth attacks man’.

Dr Fenton’s killing is a huge loss to the psychiatric community. A tribute published on the Schizophrenia Bulletin website notes his academic and scientific contributions to the understanding of the condition, and former patients have been remembering his compassionate approach to patient care.

Why email is addictive (and what to do about it)

Email is addictive

Like lots of people who sit in front of a computer all day, I am addicted to email. This worries me for two reasons. The first is the sheer strength of my compulsion. I must hit the ‘get mail’ button at least a hundred times a day. Sometimes, if I don’t have any new mail, I hit it again immediately, just to check. I interrupt my work to check my mail even when I know that I’m not going to find anything interesting and that I should just concentrate on what I am suppossed to be doing. When I come back to my office it’s the first thing I do. If I’m prevented from checking my mail for more than a few hours I get a little jumpy and remain that way until I have.

This is all rather sad, but the second reason I am worried by my email addiction is that I work in a psychology department and we’re supposed to understand how these things work. Now email isn’t a drug – it doesn’t deliver a chemical into your bloodstream. Yet it is clearly addictive. I’m a normal rational person (which is to say I’m just normally maladjusted) and I know that I don’t need to check my email as often as it do – certainly not immediately after checking it the first time for Goodness’ sake! – but still I am compelled. What’s going on, and can psychological science help me out?

Cognitive behaviour therapy creator wins Lasker Award

AaronBeck.jpgAaron T. Beck, the creator of cognitive behaviour therapy (CBT), has been awarded the Lasker Award – a prestigious prize that is given to those who are deemed to have made a significant contribution to the understanding and treatment of medical disorders.

Randomised controlled trials have shown cognitive behaviour therapy to be one of the most effective treatments for depression and anxiety (typically as good as, or better than, drug therapy) and has also been shown to be effective in a wide range of other disorders, such as psychosis, eating disorders and chronic pain.

In serious cases, both CBT and drug treatment will be used at the same time, and this often gives the best results.

Instead of focusing on early experience and childhood trauma, CBT tends to focus on the here and now, and works with clients to develop more effective ways of thinking about situations which typically lead to disturbed thoughts and emotions.

This can be achieved by understanding the link between thoughts, emotions and behaviour, by testing out assumptions and ideas, and challenging negative thoughts as they occur in the mind.

Lasker Awards are often thought to be hints as to who might win a future Nobel Prize, as 71 Lasker winners have gone on to win a Nobel.

However, the Nobel Prize committee tends not to give awards for psychological discoveries. The nearest, perhaps, was when Daniel Kahneman won the ‘Nobel Prize for Economics’ for his contributions to understanding rationality in economic reasoning.

The New York Times also has some coverage of the story and looks at some of this year’s other Lasker Award winners.

Trouble with Spikol mental health video series

LizSpikolVideoFrame.jpgLast August, we interviewed editor of the Philadelphia Weekly and mental health campaigner Liz Spikol. Part of her work as a journalist and campaigner involves her blog The Trouble with Spikol, which includes regular video updates conveying her whimsical view of the world of journalism.

Recently, she’s just begun a video series tackling current issues in mental health, drawing both from her own experience and her knowledge of psychiatric treatment and the mental health system.

The first is both frank and witty (the reference to Touched with Fire, Kay Redfield Jamison’s book on the link between creativity and manic depression made me laugh out loud) and hopefully will be the first of many to come.

The DiNET project

marc_jorge.jpgWhile in Seville, I met up with Marcos Cobe√±a and Jorge Cant√≥n, two computational neuroscientists who are involved in a project to develop a model of brain function based on Jeff Hawkins’ Hierarchical Temporal Memory framework.

Their project, based at the University of Seville, is called DiNET and aims to develop free software to implement the simulation using the Mono framework to easily enable distributed processing.

Firstly, I must thank Marcos and Jorge for giving me the chance to have my first neuroscience discussion in Spanish, and secondly, for being patient with my dodgy grammar.

One of the things I noted was their enthusiasm for the project and their intention to get as much biological detail into the model as possible, as much of the time was spent discussing details of neural architecture and pathways.

They’re also looking for people willing to join the project. They have a mailing list to discuss the project (currently only in Spanish, but they tell me that will change shortly) and updates will be appearing on the DiNET website.

I look forward to hearing more about the project as it progresses.
