The Baby MEG Study, Part II

One year ago, Junior participated in a baby MEG study. The study required him to sleep on a little bed, with the top of his head ensconced in a little hollow within the neuroimaging machine. At 13 months, he was a reliable twice-a-day napper, so we scheduled the study for his morning nap. However, being in a new environment with lots of unfamiliar, very businesslike people distracted him from his routine. The study coordinator and I spent an hour trying to soothe him, and eventually he fell asleep. Five minutes later, the research team requested that I scooch his head just a little bit more into the hollow. That woke him up, ended the study, and we walked out of there with enough money to fund many new baby outfits. So...worth it!

Note: MEG stands for magnetoencephalography. Here is further reading, if you wish, ducklings.

On Monday we went back. The study was different this time, since Junior can now follow instructions. First, they attached some sensors:

Next, they scanned his head with an instrument that looks like a handheld barcode reader. The corresponding 3D image appeared on a nearby laptop, because we live in the future. Then, when the team was ready, we went into the sealed room where the machine lay. "Our old nemesis," Junior and I said, in unison.

He lay down, and his head was almost too big for the hollow space this time around. A monitor hung from the ceiling above his feet. For the study, he had to keep his eyes on the center of the screen as images flashed and the baby MEG scanned his brain activity.

And, thank goodness, he was perfect. He dutifully watched the images, limiting his disruptive activities to picking his nose and lifting his legs to touch his toes (which blocked his line of sight). There were maybe 10 videos, each one ranging from 15 seconds to one minute in length. The images were tiny and I had trouble identifying all of them. So I used that as a way to keep Junior interested, asking him, "Does that one look like a polar bear or a snowman?" and "That must be a garden gnome! Do you know what a garden gnome is?" Shapes showed up, too, in various locations onscreen (e.g. to the right instead of in the center) depending on the video file.

Things started to look a little dicey about halfway through, as Junior became more squirmy (remember: he's two!) and started demanding to see videos of trucks instead. The researchers obliged by pulling up another window for some YouTube goodness. After every image video, he got to watch maybe 20 seconds of trucks. I also lied promised him that he could watch all the videos he wanted when we got back home.

When we finished, the study coordinator gushed that it "went really well!" As our reward, we got two gift cards. I plan to use them to buy Junior some new jeans, since he's outgrown a couple of pairs. And, y'know, momma might need a li'l something for transporting him to and from the study via my legs. New shoes, perhaps?

I took Junior to a nearby playground to stretch his legs:
For both of us, it was the perfect end to the morning.

TL;DR: Junior did a study FOR SCIENCE!!!

An International Women's Day Miracle!

Truly, International Women's Day is a special day. No, not because multitudes are out there rallying for our rights and giving voice to the powerless. It is because I won a gift card from a company raffle!

Let me explain why this counts as a minor miracle. You see, I never win anything. I answer every damned survey sent my way, participate in all the raffles, buy lottery tickets -- to no avail. This particular raffle occurred monthly, and I had been faithfully entering my name every month for two years, with no results. Finally, last month, I declared: "No more!" and unsubscribed from the mailing list -- but not before entering one final time, because why not.


There's also some déjà vu at play here. You see, four years ago, I won a gift card from a company raffle. The one fracking time I won anything! I was elated! Shortly thereafter, also on International Women's Day, I was laid off from my job.

Sooooo...since the day's almost over, I guess I'm not…

Paint Nite!

Last night I joined the "Oops" Paint Nite event hosted by the Club Cafe in Back Bay. About 12+ people came to relax and have two artists guide them through painting this original work:

The point was not to slavishly duplicate "Oops" -- we were instructed to make it our own, to relax, and not to utter the words, "Mine sucks," "Can you do this for me?" or "I thought this was paint-by-numbers!"

Speaking of dashed hopes, I had assumed that wine was included. I had done something like this before, only it was in the morning and we all got mimosas. Not so here! While the artists were setting up, I schlepped over to the bar and was rewarded with a generous pour of Cabernet. Now I was ready.

The setup: Everyone got a 16" x 20" canvas, three paint brushes, and a palette (a paper plate) with red, yellow, blue, and white paint. One artist (Brian) had the microphone and would paint with us, while the other was the assistant (Kory) who wo…

Get Out (2017)

Get Out has a charismatic lead, a terrific soundtrack, and damn good cinematography. While it’s described as horror/comedy, it’s more disturbing/cringe-y than scary, and I mean that in a good way. This is an entertaining movie that’s also pretty effective as social commentary.

The film stars Daniel Kaluuya as Chris, a photographer who’s about to spend the weekend at his girlfriend Rose’s (Allison Williams) parent’s house. Naturally, it’s in a secluded spot in the woods. When they get there, the awkwardness that might be expected from a first-time meeting gives way to a series of bizarre behaviors and interactions. While Chris initially takes it all in stride, it eventually becomes clear that there’s something sinister going on behind the scenes.

The acting and dialogue are highlights of the film, as is the camera work. In particular, Kaluuya’s eyebrows and head tilts are so expressive that the audience knows what’s going on in his head even as he politely brushes off eccentricities. A…
