I didn't actually mean diagnostically. I just wanted a picture of her on the computer.
Yeah, thinking of them as halves makes sense. I've seen 'right thalamus' and 'left thalamus' and such but the whole just called 'the thalamus'. Anyway, how was it? Did you learn anything?hypnagogue said:Actually, I believe that just the singular "thalamus" refers to both 'halves' on either side.
edit: Then again, I think I've seen thalami used as well. So, not sure what the proper usage is, or if they're equally acceptable.
It was OK. I don't have any fear of enclosed spaces, but I was still a bit uncomfortable and anxious to slide into that very small MRI space strapped down and everything. But that went away pretty quickly.honestrosewater said:Anyway, how was it? Did you learn anything?
It's here in posts 17 and 18. Sorry about the link; that function isn't working properly.

Maybe that was the real test. I wonder whether people respond to those instructions in a similar way. How exactly do you keep your mind free of thoughts? And what does that look like? Eh, I'm not asking so much as thinking out loud.hypnagogue said:Anyway, what was interesting to me about this was that if I chose to focus my attention on the trancey drones, they would actually sound different than if I paid them no particular attention. In particular, towards the end of each cycle, if I paid attention, I heard what seemed like mildly hallucinatory dancings and phrasings and echos playing off from the actual noises. (Don't know if that makes sense, it's hard to explain.) I wonder what the cause was-- I wonder if something about the magnetic field or radio waves in my immediate environment was having some subtle effect on the activity of my auditory neurons. Or then again maybe it's nothing that exotic, but it's still strange.
Yes, that structural scan was pretty trancey with the droning tones and the perpetual beat of the MRI machine floating in the background. I was also instructed during this time to stay still and keep my mind free of thoughts,
'aroused' as in your physical reaction and 'bad' as in a cognitive appraisal? I just finished reading a little about theories of emotion (I'm trying to figure out how to manage some of mine). Do you know anything about the attribution-of-arousal theory (a.k.a. cognitive arousal theory)?As for the experiment itself, nothing too special there. I was shown a series of images, some of them of negative emotional valence and some neutral, and after viewing each image I rated how aroused I felt on a scale of 1 to 5, and also how 'bad' I felt, from 1 to 5.
Well, it couldn't be after all. Who would expect a photo of an invisible man?El Hombre Invisible said:Yeah, it's not me,
Yeah, I actually laughed when the experimenter told me to do that because he just said it so matter-of-factly. "Ho hum, tie your shoes, snap your fingers, clear your mind of all thoughts." They know it's not trivial of course, but I guess there's not much more you can say. And even if you fail to keep your mind free of thoughts, just trying to do so is likely to produce a less noisy brain image than if you're letting your mind roam free.honestrosewater said:How exactly do you keep your mind free of thoughts?

They didn't really specify. I suppose they're content going with colloquial interpretations, which I don't think is bad-- intuitively, there's an identifiable feeling of being aroused and one of feeling 'bad' (I don't know if that's exactly how they phrased it, but it was something simple), and they're pretty clearly distinct.honestrosewater said:'aroused' as in your physical reaction and 'bad' as in a cognitive appraisal?
Not really, but it sounds like it might have something to do with attributing emotions to aroused states. (e.g. experiments have shown that people who are played a recording of a rapid heart beat and told that it is a recording of their own heart tend to feel anxious as a result.) Maybe post something about it over in the Mind & Brain Sciences forum?honestrosewater said:I just finished reading a little about theories of emotion (I'm trying to figure out how to manage some of mine). Do you know anything about the attribution-of-arousal theory (a.k.a. cognitive arousal theory)?
Yes, there's the pause to record assessments of arousal and affect, then there's another brief pause with a fixation point, and finally the time you spend looking at the cue. Altogether I'd say there was about 5 or 6 seconds inbetween actually viewing images. On some trials they also presented a cue without showing an image afterwards and then asked for arousal/affect ratings before repeating the cuing process.honestrosewater said:Did they give you time to recover between images?

Going to a holiday party a couple of years ago. I don't have very many pictures of me standing, I'm always sitting.Math Is Hard said:Very pretty, Evo! Where were you off to? Was this taken this weekend?
Evo said:A rare full length photo of Evo going to a party.
You are simply divine.Evo said:A rare full length photo of Evo going to a party.
By popular demand, yes. There has to be enough of you to go around.Evo said:I'm multiplying.
Nonsence. You look sweet, petite, and adorable.I have the dumbest looking grin, now you know why I don't smile in pictures.
Not at all - I agree with Zooby's assessment, especially 'adorable', and I would amend my previous statement with - "Evo, you look radiant - the epitome of elegance."Evo said:I have the dumbest looking grin, now you know why I don't smile in pictures.
