hello everyone :)
I gathered a compilation of interesting facts from various books I’ve read:
- It was previously thought that newborn babies weren’t conscious and couldn’t feel pain. So often circumcisions and surgery would be performed without any anesthesia.
- The popular theory with consciousness and fetuses is that the fetus is sedated in the womb. They are bathed in a fluid that contains natural anesthetics and sleep inducing chemicals.
- Locked in syndrome is when a person is completely aware but can’t move any part of their body except for their eyes.
- Using transcranial magnetic stimulation (TMS), researchers have been able to induce hallucinations in people, such as making them think they have smelled burnt toast or moved their arm when they really haven’t
- Psychosomatic is when a mental factor produces physical effects. The most bizarre, is pseudocyesis or when one starts to exhibits symptoms of pregnancy even though they really aren’t pregnant.
- The thalamus and prefrontal cortex of the brain are thought to be vital for consciousness
- Your consciousness can only register one item at a time. Sure you can hold a baby and read a book at the same time, but usually one of the tasks will require less attention and be automatic (holding a baby). Think of it this way, you can’t read two books at the same time can you?
