When you dream you're in REM sleep (rapid eye movement). REM sleep is only slightly more "deep" than stage 1 of non-REM which means it's not that hard to wake you up in the first place. Dying in a dream is a stressful event, which causes your brain to release adrenaline. You can't sleep and have an adrenaline rush at the same time so you wake up. These ...

Short answer: Because areas of the brain needed for remembering are turned off during dreaming. Dream Amnesia: The process of converting perception into a memory construct that can be stored is called encoding, and is essentially the same during both wakefulness and sleep: That is, the same factors can hamper or promote successful encoding when awake or ...

Assuming your question is "Is person's ego a projection of the responses of their amygdala onto the conscious experience?", I think it would translate to "Does the amygdala determines or houses the ego". In that light, the question hinges on the meaning of ego. Given the question is asked at Cognitive Sciences SE, I assume the ego is "The part of the mind ...

Short answer On the basis of a cursory literature review, I conclude that Jospeh's observations were correct, but his conclusions that a callosotomy can result in a dual consciousness were far stretched. Background First off, I'm not an expert on this topic, but I will give my referenced opinion anyway, as there is no answer yet to this question; Below are ...

Short answer: We don't know. Long answer: There are a few major lines of thinking on the subject currently. Cognitive closure: One common argument is that this question is simply not answerable - at least not by humans. By this view, it is possible that the creation of an artificial intelligence that even resembles humans sufficiently to suggest ...

State dependent memory could play a role in quickly forgetting dreams after awakening. See my question here: What is the scientific term for unexpected, spontaneous dream recall? I ask about a phenomenon where dream recall happens much later potentially weeks or months after awakening. I would venture to hypothesize that Melatonin might play a role as a ...

It is something of an oversimplification to say that there are separate visual pathways for both color and shape. There are many cells, even in V1, which are selective for both colour and shape (or at least orientation). While there are regions more sensitive to some features than others, there are plenty of neurons which combine features. It is also ...

From a quick search online I see no reason why you distantiate what you describe from auditory hallucinations: a form of hallucination that involves perceiving sounds without auditory stimulus. Given the article you link to, which arguably does address your question (yes, some people report experiencing this), you mainly seem to be concerned that ...

I don't think inverted prism goggles would be a satisfactory way to empirically test the thought experiment. A key axiom of the argument is that there are no physical changes to our brains or bodies; only the qualia have changed. In a goggles design, there would be a clear physical locus of the change (and we might reasonably call this part of your body for ...

Apparently I have a proclivity for long answers, but I thought I'd respond given the viewership on this question. We can whittle your question down to a more general form: Can my subjective experience be categorized? The answer to that basic question is of course! You made a categorization of how you felt in that moment, and you concluded that you had a ...

Neither rational nor logical "...there is overwhelming evidence that Humans cannot be [rational]" - Daniel Kahneman (Thinking Fast and Slow). To begin with, the brain is neither rational nor logical as you may think (to a large extent it is little rational and its logic is completely fuzzy). A perfectly rational and logical organ would not be able to ...

Sleep and dreaming is somewhat of a specialty of mind, so I can comment on the wake-sleep-wake transition. People typically love the feeling of relaxation and warmth associated with sleep. Waking up naturally can feel just as good - imagine lounging in bed on a Sunday morning without having to get out of bed. Waking due to alarm is an abrupt event which is ...

If by consciously perceived, you mean recognizing a feature (and possible reactions accordingly), there are several tasks to be considered that seem to cause delays: Saccades and eye movements: During saccades we are blind, so we must wait a little to bypass a saccade so participants are able to see. It is called saccade masking. Transmission: neurons are ...

I feel that the label of consciousness is merely a semantic distinction that belongs to the realm of philosophy, not neuropsychology. Like Noam Chomsky mentioned in one of his talks hosted by Lawrence Krauss - we could also ask ourselves whether animals (e.g. dogs) are conscious. I'm not exactly sure, he mentioned that birds are said to "fly" in Enlgish but ...

The general consensus of the scientific community would be that the human heart is not capable of consciousness. The machinery behind consciousness is not well understood, of course, and there is quite a bit of debate, but it is thought that some minimum level of complexity is required in order for consciousness to arise. The human heart, while containing ...

The evidence in support of binaural beats as a therapeutic tool is sketchy: Is there scientific evidence on the benefits of binaural beats? Given our lack of understanding of if binaural beats can cause entrainment in the brain, never mind how they cause entrainment, it is not possibly to make conclusions about how the binaural beat would affect the autistic ...

This reminds me of a similar question I answered a few weeks ago. Not exactly the same situation, but the leading theory is that it comes down to complexity. I'll start out by saying that we don't know for sure what animals are conscious or even what consciousness is, exactly. In fact, it's not even possible to prove without a doubt that you or I are ...

In a famous experiment Luigi Galvani conducted in 1780, he observed that a dead frog leg was twitching when electricity was applied to its nerves. Following your line of argument, electricity would be the meta-physical phenomena that gives rise to life. Brainwaves are the signature of neural activity; we capture them through electrical measurements. We ...

You have asked an excellent question. However, this innocently short question involves many dimensions: the philosophical discussion of consciousness, the neurobiological basis of motor movements, reflexive actions, relationship between sensory and motor areas in the brain etc. I'll try my best to elaborate on my answer: meanwhile, your best bet would be to ...

What do you mean exactly with 'processes'? If you're thinking about actual movements made during editing (i.e. tiping), this science paper might help. Very simply put, they showed skilled typist have two kinds of control processes, one conscious and one unconscious.

Not everyone forgets gravity in dreams. I'm speaking out of my experience with lucid dreaming, which allows thousands of people to act consciously in their dreams. This allows them to examine dream concepts in more details, as well as perform experiments. There's a lucid dreaming flying technique, which is all about manipulating the gravity within a ...

I don't think there's a real answer to the question, but I find it fascinating. Have a look at this really nice paper, too. They asked lucid dreamers to approach other dream characters and ask them to do simple maths. (Not because they were interested in lucid dreaming per se, they just needed somebody to be able to decide what they would dream). The study ...

The unusual feeling you've described here could be the variation of so called dissociative experiences, when a person's perception of the surrounding world and himself is distorted and therefore could evoke intense fear (and visa-versa). Quite often it could be the result of traumatic events in the past, which are not dangerous for a person in the present, ...

On/off is indeed not the commonest view of consciousness. In Hindu philosophical circles, consciousness is thought of as continuous across living systems. Humans have 'budding'consciousness, (plus free will), animals 'shuttered' and plants 'covered'consciousness, and these are points along a continuum. (Reference example: Hinduism and Science, by T D ...

I can't give you an informed response to questions 1 and 2 though I do know that parasitic wasps inject toxin into a spider, lay an egg on the back of the spider and cause it to spin a web that will protect the egg. So some form of behavioural control of spiders is possible. Spider brains are much simpler than human brains but there was a paper by ...

I believe an overactive amygdala certainly plays a pivitol role defines ones ego. As the amygdala is part of the limbic system. An overactive limbic system has been linked to depression, obsessive compulsive disorder and depression. While I do believe the amygdala does play a small part in defining the ego, I believe other parts of the limbic system, play ...

Most would call this an 'awakening'. There was a fad some years ago for going on courses to promote this state of awareness. I know because I went on some (and they worked!). The techniques vary but typically involved a repeated questioning of the 'goldfish bowl' and state of semi-hypnosis that we all tend to inhabit day-to-day. Some, such as "The Forum" ...

From my experience with Lucid Dreaming, a practice where people seek to be consciously aware in their dreams, searching for the term "lucid" or "lucidity" would be a good place to start. Lucid dreams vary wildly in their quality, content and level of control. Some very highly sought after lucid dreams, which are colloquially known as "epic" feature those ...

This question has perplexed me for quite a while now. The problem with declaring an artificially intelligent machine 'conscious' is the very definition of consciousness. A quick google search for the definition for 'consciousness' returns 'the state of being awake and aware of one's surroundings'. This definition in my opinion is too vague to be extendable ...
