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 ...

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 ...

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 ...

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 ...

You are describing an observation as old as Freud, where he divided human's experience into three levels, roughly along the same lines as you. The conscious as that clear and ill-defined concept that gives you the feeling of attention, awareness, and self. The preconscious as the level just outside of your current awareness but that could easily spring to ...

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 ...

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 ...

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 fusion ...

This being cogsci.SE, not philosophy.SE, we cannot simply accept a philosophical definition of consciousness. From the perspective of experimental science, there is no universally accepted operationalisation of "consciousness". For example, it is impossible to measure consciousness directly. A usual approach is to let human subjects report their thoughts. ...

Sure, to some extent mind reading "implicitly 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. But the brain is a physical object, whereas the concept of the mind is more obfuscated. Some people emphasize the experiential aspects of the ...

If you look at the paper Strong and Weak Emergence by David J. Chalmers he states his belief that consciousness is the only example we have of strong emergence. However, he also states that it is quite possible that there is no such thing as strong emergence, and therefore, our perception of the mind as an example of strong emergence stems from our current ...

Wikipedia's answer is a better answer than I could offer as to what the higher self is, because that's all you've used to define it, and as Wikipedia says, it's "a term associated with multiple belief systems," and probably differs rather widely across the gamut. Regardless of how odd some of those beliefs might get, it probably shouldn't be synonymous with ...

There's a philosophical stance called panpsychism that addresses this question. Of course, there is no proof, but the fundamental question is really about humans. Is consciousness an intrinsic property of matter or does it emerge from complex matter structures? It's probably something we'll never know, but Tononi's model of consciousness leans towards ...

Here's a study on Brain Response to One's Own Name in Vegetative State, Minimally Conscious State, and Locked-in Syndrome: http://archneur.jamanetwork.com/article.aspx?articleid=791093 Background A major challenge in the management of severely brain-injured patients with altered states of consciousness is to estimate their residual perception of the ...

Nick Stauner’s reply has some nice discussion about concrete existing work; we also discussed some more speculative possibilities in (Sotala & Valpola 2012), considering the possibility of merging together the minds of two distinct people so that they could share thoughts and skills. In particular, we considered the possibility of “exocortices”, neural ...

In many languages, there is no word similar in meaning to the English word mind. In my opinion that fact illustrates an inherent problem with the scientific use of that word: that mind does not even denote a unified concept at all. The Oxford English Dictionary lists the following current meanings of mind, among others ...

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 ...

Studies examining unconscious perception usually rely on the experimental logic known as the dissociation paradigm (Reingold & Merikle, 1990), whereby the presence of subliminal perception is supported by a dissociation between two measures of perception. One measure is assumed to provide an index of subliminal perception whereas the other is assumed to ...

Your own theory is bad because it seems to follow from a Lamarkian interpretation of evolutionary theory. In Lamarck's idea, a crab's offspring will have the genes bigger claws if the crab exercises his own claws a lot before giving birth. In the same way, you're suggesting that the way ancient human diets improve their mental health somehow led to this ...
