Dana neuroscience radio

dana_monitor.jpgWhile browsing the ever-vigilant (and mildly addictive) Neurofuture blog I was alerted to the fact that the Dana Foundation have an archive of podcasts online, including their Gray Matters radio series and other in-depth neuroscience discussions.

They include a conversation with Nobel Prize-winning neuroscientist Eric Kandel, Nancy Andreasen on the creative brain and a number of other wide-ranging programmes on everything from neuroethics to mental illness.

Also available is a page with all the programmes as realaudio files.

Online communities in the 1800s

joinson_internet.jpgAdam Joinson discusses the process of community building via technology in his book Understanding the Psychology of Internet Behaviour (p11, ISBN 0333984684), noting that there is nothing new under the sun:

The cost and lack of privacy tended to inhibit personal communication between members of the general public using the telegraph. However, for the telegraph operators the network provided an ‘online community encompassing thousands of people, very few of whom met face-to-face’ (Standage, 1999, p122-3). The sense of community among telegraph operators was heightended by their own norms and customs, vocabulary, the use of short (usually two or three letters) signatures or ‘sigs’ and the sense of ownership of a particular line. According to Standage, experienced operators could even recognise their on-line friends simply from their style of morse code.

Freud birthday roundup

Sigmund_Freud.jpgToday is the 150th birthday of the late Sigmund Freud, controversial granddaddy of psychoanalysis who sparked off the modern interest in the unconscious and the use of ‘talk therapies’ in treating mental distress.

The Times has a critical article examining his legacy and finishing with a tongue-in-cheek quiz to test your knowledge of the great man and his theories.

Alternatively, The Calcutta Telegraph has a piece on Freud’s last surviving patient, Margarethe Walter, who spoke at an event to celebrate the anniversary.

The National Ledger starts an article by looking at the amount of kitsch freud merchandise available, and goes on to examine the relationship between Sigmund Freud, and his daughter Anna Freud, in a remarkably well-informed article that muses on the possible impact of this on Freudian theories.

And now’s probably a good time to revisit the five-part BBC Radio 4 series Freudian Slips – a series of 15 minute programmes each dedicated to one of Freud’s key works. The series is archived online.

BBC All in the Mind on the impact of combat

kwame_mckenzie.jpgBBC All in the Mind has a special on the psychological impact of combat and military psychiatry.

New presenter and psychiatrist Dr Kwame McKenzie investigates the mental health provisions of the armed forces, and the new developments introduced to support the emotional well-being of soldiers operating under intensely stressful conditions.

Dr Kwame McKenzie takes a look at the mental health of the military. With nearly one in 5 US soldiers returning from Iraq with psychological problems there’s growing concern about the mental health of soldiers. Dr McKenzie attends a NATO conference in Brussels looking at psychological support, and talks to Major General Patrick Cammaert, a former Dutch Marine, who now leads 15,000 UN peace keepers in DR Congo. Lieutenant-Colonel Carl Castro and Dr Brenda Wiederhold explain how the US is using predeployment briefings and Virtual Reality to help soliders cope, and Professor Simon Wessely talks about the situation in Britain.

The Army is using the psychological model of Transformational Leadership to reform its training regime, and All in the Mind visits the Infant Training Centre at Catterick to see if it’s making any difference to new recruits.

And Dr McKenzie talks to two veterans being treated by Combat Stress about their psychological breakdowns following active service.

Presumably, they mean Infantary Training Centre rather than Infant Training Centre!

Ripples of yawn

bw_yawn.jpgSeed Magazine has a short but thought-provoking article on the yawn and the mysterious way they are ‘transmitted’ around a social group.

Scientists maintain that yawning has both social and physiological functions, and may even be useful clinically: Abnormal yawning can be symptomatic of pathology, such as tumors, hemorrhage or drug withdrawal. Researchers know that a system of several neurotransmitters and neuropeptides control yawning, but little is known about the exact mechanism underlying the action.

Until recently, it was thought that only humans and great apes were able to “catch” yawns. While humans yawn in the womb, they don’t fall prey to contagious yawning until about two years of age, which suggests a recent evolutionary origin.

The article also tackles the myth that yawns are brought on by lack of oxygen.

Cognitive science video interviews on Slate

dennet_slate.jpgSlate has a collection of streamed video interviews with significant public figures online, including a couple of cognitive scientists.

A comprehensive interview with Daniel Dennett tackles his views on the supernatural, evolution, consciousness and free will.

Stephen Pinker is also interviewed and discuses evolutionary psychology, consciousness and the limits of science, although from quite a different angle.

Apparently, the interview with Francis Fukuyama also strays onto consciousness, although I haven’t listened far enough to discover for myself yet.

For a change, the interviews are in-depth and gives the speakers a chance to develop their ideas and really make their points.

NewSci on reading the mind by measuring the brain

ns_20060506.jpgThe cover story on today’s New Scientist is about recent efforts to determine what people are thinking by viewing their brain scans.

Although you may think this is what neuroscientists already do, in most brain-scanning experiments the researchers will know exactly what the participants are experiencing in the scanner, and they just link the measured brain activity to the known task.

Recently, researchers have been able to work out what the participants are viewing by only looking at their brain scans.

Although these experiments are quite simple so far – the researchers typically know that the participant is viewing one of several simple options and just have to work out which – the idea that mental states can be ‘read’ is causing some excitement. Not least because this has been the subject of many science-fiction novels and films.

The accuracy of these experiments is typically much better than chance, although it is far from perfect and so far has largely relied on very simple tasks (viewing lines and the like):

In published results, Tong and Kamitani were able to predict correctly 56 per cent of the time which of eight orientations of lines people were seeing, compared with 12.5 per cent for chance. When subjects were shown a grid of criss-crossing lines, the researchers predicted correctly 80 per cent of the time which lines were being attended to (Nature Neuroscience, vol 8, p679, pdf).

Unsurprisingly, this has sparked some neuroethical concerns. For example, the technology might advance to the stage where it could be used to narrow down what people were thinking regardless of whether they consented (e.g. in interrogations).

The article isn’t freely available online, but your local library or newsagent should have a copy.

Opposite Emotional Expressions

The Facial Action Coding System is a system for describing facial expression. It is based on 46 defined ‘Action Units’, which are each the contraction of a facial muscle or group of muscles.

So, the six basic emotional expressions can be expressed in terms of combinations of action units. Disgust is Action Unit 7 + Action Unit 9, for example.

Described in terms of the Action Unit space, each emotion must have an inverse (when all involved action units are inactive, and all action units not involved in the expression of that emotion are active).

Question: What do the Action-Unit Space inverses of the fundamental emotional expressions look like? Are they recognisable in any way as the opposite of the expression in emotional space? Does the action-unit inverse of sadness look like happiness, for example? What is the muscle-opposite of surprise, is it similar to the feeling-opposite (boredom presumably)?

An influential psychologist

What got you going where

biomapping.JPGBy combining a hand-held global positioning system with a galvanic skin response sensor (that measures the sweatiness of your fingers), London-based artist Christian Nold has created a gadget that measures your arousal as you walk around. Superimposing the data onto your route, using something like Google Earth, allows you to see a kind of ’emotion map‘ for where you’ve been.

Nold has tested the device on over 300 people so far (his data is publicly available), and is looking for academic and commercial research partners to explore the project’s potential.

The art and science of autism

wiltshire_frame.jpgABC Radio National has a Health Report special on the science, myths and realities of Autism Spectrum Disorder.

The show talks to psychiatrists Dr John Constantino and Dr Eric Fombonne who discuss the features and attributes that a diagnosis of autism describes.

They also tackle the evidence for claims of an autism epidemic and the controversial link between autism and mercury-based vaccinations.

On an artistic note, the Wisconsin Medical Society has some online video of artist Stephen Wiltshire MBE who has autism and was featured in Oliver Sacks’ book An Anthropologist On Mars.

Wiltshire is taken for a helicopter ride to view Rome, and subsequently demonstrates his startling artistic talents by drawing an almost perfect, four metre long aerial panorama of the city.

Electricity, let it rain all over me

Robinson_Electricity.jpgI’m just reading Ray Robinson’s breathtaking debut novel Electricity (ISBN 0330444506) about Lily O’Connor – a young woman with epilepsy and a troubled past who’s trying to track down her lost brother.

Robinson wrote the novel as part of his PhD in creative writing and spent a considerable amount of time reading scientific literature on epilepsy and interviewing people with the condition.

Although the book doesn’t attempt to explain the science behind it, it does brilliantly capture the idiosyncratic experience of epilepsy in the sometimes wonderfully poetic language from the book’s protagonist – an otherwise plain speaking northern girl.

the room cracks and shatters, the colours wrapping their arms around me but I can’t hold them back, it’s like rain running down windows, the air’s melting in front of me, colours like feelings inside, suffocating but nice
   like storm clouds up there
   like bullies, black lightning off and on in their fat bellies and I need to pull at everything, need to touch and tug and twist and poke and push because it’s all slipping away from me
   and I know

   I know she’s here in my room, but I can’t let go of the chair, my fingers crack-cracking the corners and I

   can’t catch my

The Architecture of Happiness

de botton.jpgWe’re probably going to be seeing a lot of Alain de Botton in the coming months, as he’s out and about promoting his new book ‘The Architecture of Happiness’.

I’m a huge fan of de Botton, whose books such as ‘The Consolations of Philosophy’ have won widespread critical acclaim for making philosophy accessible and relevant to modern life.

But I felt he went off the boil with his last book Status Anxiety and after reading Jonathan Glancey’s review of his new book in The Guardian, I’m worried he may not have found a return to form.

However, I am going to read the new book (partly because I‚Äôm researching a feature on the role of psychology in Britain‚Äôs current building boom) so if there are any magazine or newspaper editors out there who‚Äôd like me to review it, please do get in touch 😉

Also, while we’re discussing de Botton, I should point you to his Times review of Cordelia Fine’s book ‘A mind of its own’, in which he discusses whether the experimental approach to understanding the human psyche – that is, psychology – really is the right one:

“Expecting to study the mysteries of the mind, [psychology] students soon realise that they have set off down a far less glamorous and unusual path, for their field requires them not so much to explore new insights as to test old and quite simple ones according to a rigorous and patient scientific method. Psychology emerges as, depending on your point of view, either a gloriously or horrifyingly pedantic discipline”.


PS. I virtually bumped into de Botton at Edinburgh airport once, but I’m (a) not that good with faces and (b) shy, so I persuaded my girlfriend to go and ask him if he was who I thought he was. Anyway, apparently he was utterly charming and self-effacing.

UPDATE: Alain de Botton appeared on Monday’s edition of Start the Week on BBC Radio 4. And he’s got his own TV series on Channel 4/ More 4.

The Happiness Formula

the happiness formula.gif
There’s a new six-part series starting on BBC 2 this week called The Happiness Formula, and the companion website has all sorts of features including on-line video clips, happiness tests, and an article about the science of happiness.

Glancing through, it looks like among the key contributors are well-being psychologist Ed Diener, positive psychologist Martin Seligman, and Emeritus Professor of Economics Lord Layard, who’s been making a lot of noise recently in an effort to get the UK government to provide more therapists. Layard also wrote a book a few years ago called Happiness: Lessons from a new science.

The series comes at a time when there are increasing calls for the population’s happiness, rather than it’s prosperity, to be used as the main measure of the government’s success.
