Sleepwalking happens in NREM3 when the mind is in a deep sleep…so what’s controlling the movement?

When I’m walking or doing some complex tasks, I think there’s quite a lot of conscious involvement. During NREM3, the muscles are supposed to be relaxed. There shouldn’t be any conscious.

So how are they still able to walk and/or perform complex tasks? Where are they walking to? Do they have logic, coordination, or sense of direction? And suppose they hit an obstacle, do they awaken or somehow have the logic to turn around?

Neuroscience is just so fascinating to me.

Sleepwalking occurs when the skeletal muscles accidentally get a message saying “we’re awake, you can move normally now,” while the rest of the body is still getting the sleep message.

As for the rest of the questions, it’s kind of like being blackout drunk. The conscious part of the brain is checked out, but the body is still going. Sometimes there’s a logic and motive behind what a drunk person does, other times it doesn’t make any sense. Kind of a similar thing with a sleepwalking person.

if you like neuroscience i will tell you straight away look into it and see if you want to go down that career path sleepwalking is called somnambulism in neurscience terms. let me stop ramblering and get into the stuff you asked:)

so the motor cortex and the amygdala are active when that said person is asleep. this means that areas are responsible for controlling movements during sleepwalking. people who sleepwalk are awake their eyes may be open and they can often move well around familiar objects, when you spend enough time around something you learn the layout 😀
