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 ...

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 ...

I don't know what precisely "nerve signals" is supposed to refer to, but neurons exchange information mainly via one pathway: neurotransmitters. And these do not travel the synaptic cleft via quantum tunnelling - obviously, since quantum tunnelling is a phenomenon on a quantum scale (concerning electrons), while neurotransmitters are far larger, at the ...

During REM sleep (during which dreams seem to occur), we experience muscular atonia – our muscle can’t move. When the region responsible for muscular atonia is impaired, patients seem to live through their dreams. It has been studied in cats by Michel Jouvet.
I believe that this shows that it is reasonable to trust our subjective experience here : we are ...

Apparently your question is on backward masking, which means that the masker follows the stimulus (probe) in time. Backward masking generally occurs at higher levels, typically the cortex. In case of visual stimuli this can be the primary visual cortex, or V1 (Mace et al. 2005). Ongoing processing of the probe is then thought to be interfered with by the ...

My answer to the question is yes. I have personally experimented (not voluntarily) conscious dreams a few years ago.To be more precise, I was conscious in dreams but also conscious to dream.
Of course this answer is a testimony, not a scientific proof, of the existence of conscious dream.
But maybe in cognitive science, many serious testimonies constitute a ...

Introduction
Your thoughts seem to straddle panpsychism and computationalism. It is also possible you are just raising a question about physicalism: "if mental thoughts are a result of physical interactions, then why would consciousness be limited to things with brains?". Well, the short answer is that it's fundamentally not, but neither is a ...

If you are searching specific part of the brain, I think that frontal regions of cortex will be an answer(In particular, the dorsolateral prefrontal cortex which was associated with self-focused metacognitive evaluation). But, as it common in real life, becoming aware of dreaming state required coordinated work of different parts of brain.
You can read this ...

This is a complicated and loaded question. As Neuroskeptic noted, our understanding of consciousness is very poor (in fact, we don't know how to define it most of the time). To see some of the best current definitions, take a look at:
What are current neuronal explanations and models of 'consciousness'?
We definitely can't infer arbitrary properties of ...

Research exists on craniopagus twins, maybe most notably Tatiana and Krista, who seem to share sensory input somewhat. I doubt that connective mechanisms such as this abnormal case would suffice to permit "compound cognition" in ways that would enhance cognitive ability similarly to your point about hominid evolution. Your relatively simple proposal for a ...

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 ...

This is partially an aspect of the binding problem.
Sensory information arrives in parallel as a variety of heterogeneous hints, (shapes, colors, motions, smells and sounds) encoded in partly modular systems. Typically many objects are present at once. The result is an urgent case of what has been labelled the binding problem. We must collect the hints, ...

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 ...

David Chalmers has argued against the thermostat view, suggesting that adaptation to the environment is not sufficient. John Searle also disagrees that the current state of machine learning is capable of consciousness on the grounds that information processing is not a sufficient criterion (public lecture, 2016). Both of these philosophers emphasize clarity ...

Q: Does our consciousness die when we go to sleep or fall into a coma?
A: No, neuroscientifically speaking, the consciousness does not die when we are sleeping or are in a coma; it is just in a sleep mode or in a severely depressed mode. This is because the group of neural circuits that function to create consciousness (ref 1, 2, 3) does not die when we are ...

Don't know the answer (I think no one does), but you should have a look at this paper: A sensorimotor account of vision and visual consciousness. O'Regan JK, Noë A., BBS 2001 PUBMED
In short the proposed answer is that modalities are subject to different sensory-motor contingencies. For example, when you move forward the visual input undergoes very ...

I have never heard of this formula, but from a cognitive psychology point of view you might look the theory of expert performance (Ericsson et al., 1993). In this theory it is argued that an important factor in the aquisition of expert performance is what the authors call deliberate practice. What is meant by this is an activity, wherein someone actively ...

If non-human animals do have intelligence too, why is their intelligence not as advanced as humans?
Notions like “advanced” or “better” really have no place in evolutionary thinking. Again, evolutionary fitness is about self-reproduction and success compared to whatever competition is present at any moment. There is no force “optimizing” species to meet ...

Wikipedia is often a good place to start for basic questions like these. Wikipedia has separate pages devoted to the mind, the brain, and even the mind–body problem, which is one example of the many theoretical challenges implied by the distinctions between "mind" and "brain". Simply stated:
The brain is a physical organ. It's entirely possible that much of ...

what has always puzzled me is the neurobiological basis that gives
rise to the phenomenon that we associate our bodies with ourselves –
i.e., why does my brain think of my physical body as "me" and make me
care for it? In other words, why is me me at this particular point in
time and not some other body living e.g. centuries ago? Why do I not

Note: This is not intended to set a verbosity standard for answers, but to give a comprehensive example of what kind of information I am looking in order to further clarify the question. An answer including only a parallel of the principles of ecological psychology subsection would be sufficient, for example.

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 ...

Let's first be clear that we didn't evolve from monkeys/apes/etc. That's a common misconception. Evolution states that we and monkeys/apes/etc. evolved from a common ancestor. Same with fish. If you go back far enough, we and fish share a common ancestor... we did not, however, evolve from today's Salmon or Macaque.
That being said, the origin of ...

Consciousness is a broad concept.
In a binary world (conscious/not conscious), biological evidences are irrefutable. For example, a 2009 Brain article stated that "Impaired consciousness during temporal lobe seizures is related to increased long-distance cortical-subcortical synchronization." (Arthuis et al.). A 2012 Lancet Neurology article had the ...

Sure, to some extent mind reading implies brain reading. For instance, if you were reading someone's mind by their behavior or their heart rate, it would be through their brain's effect on those organs. We largely do this through inference. Without a heart monitor or perspiration monitor, we have whole sections of brain dedicated to recognizing human ...

Just speaking from personal experience, I've never experienced time distortion in my dreams as extremely as you describe. I've experienced moments scattered throughout narratives that would take longer than 20 minutes to elapse in real life, but since I never recall experiencing every single moment of those narratives, I wouldn't assume my sense of time had ...

Your question is about the hard problem of consciousness, which is basically the question of how qualia can be explained in a mechanistic way. As alluded to by the name of the problem, it's hard to give a satisfactory answer. The answer right now is: we don't know.
There are some theories about how qualia and consciousness could have a neural basis (see this ...

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 ...
