Hungover thinking


There aren’t many upsides to hangovers, but I can think of a couple:

The guilt they induce serves as a kick up the arse: a push to do something productive as soon as you’re able, to make up for having had to mope around doing very little while the hangover lasts.

(Entirely by serendipity, I’ve just discovered that a word for this is metanoia, meaning a life change resulting from spiritual conversion or penitence, from the Greek metanoein, to change one’s mind. I discovered this while looking up the definition of metonymical, which I mistakenly thought was spelled with an “a” (meta-), for the next paragraph but one: I had hoped it might be an adjectival way of describing something as being meta, in the sense of having a recurrent higher order.)

However, it’s a second upside I’m more interested in here. (Although it’s related to the arse-kicking upside, in that it also has implications for productivity.) It’s that I think differently when I’m hungover.

I’m convinced this is true. When I’m hungover I'm more observant; I'm more inclined to think and to think at length; I tend to think about deeper and more complex subjects; a broader range of ideas seems to be available to me; and I'm more productive in my thinking.

I don’t think this is narcissistic: I make no claims to think well in any state, it's that I have thoughts and ideas when hungover that I wouldn’t otherwise have – or at least not as readily. The ideas underlying many of the posts on this blog came to me when I was hungover - including, predictably but pleasingly metanymically (see above: I’m coining the term. I never use the word metonym anyway: that’s why I had to look it up), the idea for this one. 

I’ve recognised this for a while: I’ve long thought it helpful to consider important decisions while sober, drunk and hungover, partly because I spend not-insignificant portions of my life in the latter two of these three states, so it’s only fair for my sober self to take my drunk and hungover selves’ opinions into consideration, but also because I know that being drunk or hungover might facilitate inspiration.

Is this property of hangovers particular to me, or is it true for everyone? I don't know. There must have been reams written about the effects of alcohol, but I haven't read much of it. I know Hemingway said that whiskey put his thoughts on a different plane, but I assume he meant on imbibing, not the day after.

I doubt there’s been much if any research into how substances affect thought patterns beyond matters of addiction and impulse control. There ought to be. If anyone knows of any or has any good references on the subject, please do leave them below.

Meanwhile, I need to get up off my arse and do something with my day.

Get The Most Out Of Your Brain

How can you wring the most out of your sorry excuse for a brain? That poor, poor organ you won't stop dousing in alcohol for more than 19 hours at a time?

Lend it to someone else, that's what!

That's what I did back in 2010, when I answered an ad in the Guardian jobs listing looking for volunteers to take part in an MRI study in exchange for photos of my brain.

I'm an adverturous sort, if the adventure involves staying inside and lying down, as well as a bit of a neuro geek, and so I thought I'd give it a go.

Why am I telling you this now?

Because today I received an email from the person who led the study, one Emer J Hughes, who very kindly sent me a PDF of the first paper to emerge from it: 'Regional Changes in Thalamic Shape and Volume with Increasing Age', published in NeuroImage.

The study found that the thalamus, the part of the brain that as Hughes says in her introduction 'plays a critical role in the coordination of information flow in the brain, mediating communication and integrating many processes including memory, attention, and perception', decreases in volume with age, as do its connections with the frontal cortex, and that these changes correlate with decreases in attention, working memory and executive function.

So, basically, age-related mental decline may be partly due to weakened connections between certain parts of the brain.

As far as my own part in the study goes, I remember being told (after the tests were over) that I'd done remarkably well at remembering long strings of numbers and then recounting them back in reverse order. I would be concerned that my supremacy at this feat might have single-handedly skewed the results, except that I was also completely inept at mentally rotating 3D images, and even worse at thinking of words beginning with a certain letter under pressure of time constraints.

"Aadvark ... Ambulance ... Animal ... ... ... I said Aardvark ..."

The process of being MRI scanned was also fun, although I suffered fairly extreme vertigo once the machine got going, and had to fight mightily not to fall asleep.

Part of the scanning also involved undertaking tests of reaction time while in the machine, via a very basic visual display and some hand-held triggers, and even though I knew from my work that the test was designed to frustrate, I still felt terribly guilty that I wasn't able to do the impossible feat I was being instructed to do. Would the whole study fall apart because I couldn't fire off buttons fast enough?

Turns out no.

And what of my scan? Take a gander:


In conclusion: taking part in research is fun! Oh, and something about ageing.
