Science v Philosophy

Any friendly philosophers or scientists fancy getting together for a discussion on G+ Hangouts in the next few days?

UPDATE: The Hangout is planned for 21/2/2013 1730 GMT. Comment here or tweet @tom_hartley for an invitation. You will need to provide your preferred gmail address (but you should do this privately, e.g., by twitter DM or by adding me on G+).

Dr Who or Professor Who? On Academic Email Etiquette

This post was provoked by a discussion with a UK-based professor (let’s call her Rebecca Smith, not her real name) who mentioned on twitter that she had received an inquiry about a PhD application by email from someone addressing her as “Hey Rebecca!” Was this a faux-pas on the applicant’s part?

Devil’s Advocate: Uncorrected Stats and the Trouble With fMRI

This rather technical post is a response to a recent Observer article by Vaughan Bell. In it he follows up on a recent internet discussion around the validity or otherwise of fMRI methods. A blog post by StokesBlog responded.  I must admit I hesitate to step into the fray. I think “flaws” in neuroimaging methods are sometimes overstated, but I don’t want people to think I am flawed, so perhaps I should keep my head down. Oh well, here goes…

Identifying a Hidden Talent – Remembering Places

In previous posts, I described the science behind the Four Mountains Test, a memory test which we developed using computer generated landscapes to assess the ability to recognize places from their layout even when the viewpoint changes. The test was designed from the outset to depend on a part of the brain, the hippocampus, which is important in forming new memories of the events we experience but also in maintaining a sense of direction and keeping track of where we are as we move about. We found that patients with damage to the hippocampus had particular difficulty with the test.

The Four Mountains Test

Think of the last time you attended a wedding. You can probably remember the room around you, the place where you sat, the other guests around you and so on. Forming this type of memory depends on the hippocampus, an ancient part of the brain that is buried deep in the temporal lobes, a few centimetres in from your ears. People with damage to the hippocampus are unable to form new long-lasting memories of events and it is also one of the first parts of the brain to be affected in Alzheimer’s Disease. Being able to test abilities that depend on a fully-functioning hippocampus could one day be useful in identifying more serious memory problems that might require further investigation and treatment.
