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 ...

Parallel processes are often studied in a so called 'dual task' paradigm, where participants are drawing a picture and reciting a poem or, as in your example, counting and thinking about other things. Often this method is used to demonstrate limits in attention and find insights into how the brain works (in a serial versus parallel manner). Training is an ...

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 ...

I have to partly disagree with schultem here-- he is right that the dual task paradigm is used to study multitasking, but the idea that we can truly do two cognitive tasks at the same time is still contentious. In particular, the opposing view might say that we can't really do two cognitive processes at the same time, but we are in fact switching between the ...

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 ...

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 ...

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, ...

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 ...

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 ...

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 ...

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.

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 ...

The presentation of flickering lights usually leads to so-called steady-state visual evoked potentials, that is, oscillatory responses in the visual cortex with the frequency of the stimulus as well as its harmonics. See for example: Herrmann CS. (2001) Human EEG responses to 1-100 Hz flicker: resonance phenomena in visual cortex and their potential ...

I don't think the scientific literature would necessarily describe the process as "shifting thought between subconscious and conscious awareness" but putting exact definitions aside, obviously this does occur. When I recall information, in some sense information is being moved from the unconscious to the conscious part of my mind. By focusing on a different ...

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 ...
