Psychology Sleep deprivation impacts particular brain regions differently

[Dannnnnnnnnn]

Pulling consecutive all-nighters makes some brain areas groggier than others. Regions involved with problem solving and concentration become especially sluggish when sleep-deprived, a new study using brain scans reveals. Other areas keep ticking along, appearing to be less affected by a mounting sleep debt.

As the co-author, Derk-Jan Dijk suggests:
"We’ve shown what shift workers already know: being awake at 6 a.m. after a night of no sleep, it isn’t easy. But what wasn’t known was the remarkably different response of these brain areas."

When I'm at work a typical day starts at 4pm and finishes at 10am.Sleep deprivation is a given.I'm a big fan of the 90 minute sleep cycle,I'd rather have 3hrs than 4 hrs as I wake up feeling better after 3.

Yeah, Nightshifts sure are a fun experience...

I can attest to this as well. I've had quite a few insomnia-affected nights on my time, and 3 hours does feel remarkably better than 4.

“The process of sleep may be involved in brain ‘wiring’ in childhood and thus affect brain maturation,” explains Salome Kurth, first author of the study published in Frontiers in Human Neuroscience, and a researcher at the University Hospital of Zurich. “This research shows an increase in sleep need in posterior brain regions in children.”

Sleep in general is an extremely interesting subject to me; it's something we've done for thousands of years despite the apparent evolutionary disadvantage it conveys...yet we still don't know a whole lot about it. It's quite remarkable.

Ive worked night shift for the past 7 years and nothing in the op article is a shock to me. Wouldn't of thought they needed a study team to come up with that stuff. One thing I would be intersted in would be to study the effects of people coming down from party drugs vs those that have had none but been awake for the same length of time ie, all nighter. IME the scattered mind type effects are quite similar which really paints a different picture on mind altering chemicals that already exist in everybody Vs ingested ones.
