Neuroanthropology

I just gave a lecture on hominin brain evolution, and it’s left my own brain kind of fried. So no clever posting from me (‘Is there ever?’ I hear the skeptics asking…). I’ll just share these slides. All the graphics have been captured from different online sources — I’ve done my best to put in appropriate credits, but that’s sometimes been difficult (or I’ve just been working so late that I forgot to do it). If I’ve included something you’d prefer I don’t, and if you’re the one who has the rights to something, just drop me a line and I’ll quickly cease and desist. My goal is only to share around the resources, not to take credit for anyone else’s work.

It’s a big file (about 3 mb), so it might take a minute depending on your connection.

A word of warning: I made this in Keynote on a Mac, so the animations and transitions might not do well on Microsoft Powerpoint. The video is no longer embedded. Here it is from Youtube:

Obviously, I don’t take the video at face value. Not just the claims about meat but also assuming that humans are the ‘most developed species’ on the planet. But it’s a great jumping off point for a discussion of diet and evolution. I did an earlier piece on this subject at: Red meat, Neandertals were meant to eat it.

If you’re interested in the whole course I’m teaching, I have previously posted the unit syllabus: Human evolution syllabus.

The new Grand Rounds of medical-related blogging is up at A Chronic Dose. This week has an education theme, including sections on language, insider lessons and expert lessons, and then the school of life. Definitely a worthy edition, so check it out!

Jazz and the Art of Medical Presentations and the pimping of students (singling them out for repeated questions until humiliation or something similar is reached) are two very different takes on the art of interaction, that’s for sure!

Vaughn at Mind Hacks is one of my favourite neuro-bloggers, not only because he once referred to us as the ‘mighty’ Neuroanthropology, but also because he maintains his prolific output while still finding ample opportunities for inducing the unexpected snort-laugh (you know the one — you’ve just scanned his site because you want to sip your coffee and eat a muffin, so you can’t keep typing, and he writes something that causes you to have to clean up your keyboard, cursing him at the same time that you appreciate the barb…).

He writes about the developmental impact of Microsoft Word’s ‘auto-correct’ function (I only say ‘auto-correct’ because that’s what it’s called — sometimes it’s more like ‘obdurately-mangle’). He refers to the disorder as Bell’s Frontal Nomenclature Hypertrophy Syndrome in his post, ‘Computers cause abnormal brain growth – proof!‘ The part that caused my snack-related accident was a line about the growing frequency of the phrase ‘cingulated cortex,’ with the likely culprit being the ubiquity of the ‘auto-mangle’ function on Word.

There are 15 uses of the phrase “cingulated cortex” from 1900 to 2000. There are 1,740 uses from 2000 to now.

There must be a variant of the disorder, however, that’s caused by the auto-hyperlink function (which I know there should be some way to disable, but it would require me to become even more intimate with Word — a man has to draw the line to save his dignity!). And perhaps another one linked to the sometimes unexpected ways that Word decides you’re trying to achieve some formatting trick — like indented, numbered paragraphs. I feel like I have to watch what I’m typing to catch these software ticks, as my document gets auto-corrected, auto-formatted, and auto-linked in various ways that I emphatically reject. It’s certainly changed my visual search behaviour while typing, but it may also be undermining my linearity of narrative thought as I must constantly engage in recursive software checking, rendering my internal narrative a kind of play-and-replay, like a mad scratcher on an out-of-control turntable. But then again, maybe it’s just my midweek sleep deprivation as I try to complete slides on Human Brain Evolution and Dietary Change for tomorrow’s lecture…
