Mirror neuron

Mirror neuron
A mirror neuron is a neuron that fires both when an animal acts and when the animal observes the same action performed by another.[1][2][3] Thus, the neuron "mirrors" the behavior of the other, as though the observer were itself acting. Such neurons have been directly observed in primate species.[4] Birds have been shown to have imitative resonance behaviors and neurological evidence suggests the presence of some form of mirroring system.[4][5] In humans, brain activity consistent with that of mirror neurons has been found in the premotor cortex, the supplementary motor area, the primary somatosensory cortex and the inferior parietal cortex.[6] The function of the mirror system is a subject of much speculation. Discovery[edit] Further experiments confirmed that about 10% of neurons in the monkey inferior frontal and inferior parietal cortex have "mirror" properties and give similar responses to performed hand actions and observed actions. Origin[edit] In monkeys[edit] In humans[edit]

Theory of mind Definition[edit] Theory of mind is a theory insofar as the mind is not directly observable.[1] The presumption that others have a mind is termed a theory of mind because each human can only intuit the existence of his/her own mind through introspection, and no one has direct access to the mind of another. It is typically assumed that others have minds by analogy with one's own, and this assumption is based on the reciprocal nature of social interaction, as observed in joint attention,[4] the functional use of language,[5] and the understanding of others' emotions and actions.[6] Having a theory of mind allows one to attribute thoughts, desires, and intentions to others, to predict or explain their actions, and to posit their intentions. Theory of mind appears to be an innate potential ability in humans; one requiring social and other experience over many years for its full development. Different people may develop more, or less, effective theories of mind. Development[edit] Autism[edit]

Automates Intelligents La découverte des neurones miroirs est absolument renversante. Les neurones miroir L'une des plus grandes révolutions scientifiques de notre temps - selon moi, la découverte des "neurones miroirs" - n'a pas encore reçu beaucoup de publicité. The discovery of mirror neurons is the single most important "unreported" story of the decade. Les neurones miroirs sont des neurones qui s'activent, non seulement lorsqu'un individu exécute lui-même une action, mais aussi lorsqu'il regarde un congénère exécuter la même action.

Cache Cab: Taxi Drivers' Brains Grow to Navigate London's Streets Manhattan's midtown streets are arranged in a user-friendly grid. In Paris 20 administrative districts, or arrondissements, form a clockwise spiral around the Seine. But London? A map of its streets looks more like a tangle of yarn that a preschooler glued to construction paper than a metropolis designed with architectural foresight. These navigational demands stimulate brain development, concludes a study five years in the making. Neuroscientist Eleanor Maguire of University College London (U.C.L.) first got the idea to study London cab drivers from research on memory champions of the animal world. Maguire wondered whether London taxi drivers also had larger-than-average hippocampi. In her earliest studies, Maguire discovered that London taxi drivers had more gray matter in their posterior hippocampi than people who were similar in age, education and intelligence, but who did not drive taxis. There are several ways to explain the ballooning hippocampus.

Philosophy of mind A phrenological mapping[1] of the brain – phrenology was among the first attempts to correlate mental functions with specific parts of the brain Philosophy of mind is a branch of philosophy that studies the nature of the mind, mental events, mental functions, mental properties, consciousness, and their relationship to the physical body, particularly the brain. The mind–body problem, i.e. the relationship of the mind to the body, is commonly seen as one key issue in philosophy of mind, although there are other issues concerning the nature of the mind that do not involve its relation to the physical body, such as how consciousness is possible and the nature of particular mental states.[2][3][4] Mind–body problem[edit] Our perceptual experiences depend on stimuli that arrive at our various sensory organs from the external world, and these stimuli cause changes in our mental states, ultimately causing us to feel a sensation, which may be pleasant or unpleasant. Arguments for dualism[edit]

100 Ways To Become More Conscious: How To Raise Your Consciousness 1. Connect with nature – Go for a walk in the forest, jungle, field of daisies, or wherever you feel like getting a connection with nature. It is possible to feel at deep sense of peace and oneness when you attempt to connect with nature. As you learn to connect and appreciate nature, you allow your consciousness to rise up. 2. – Exercise and dancing will raise your consciousness by promoting healthy brainwave patterns, healthy neurotransmitter levels, and great circulation throughout your nervous system. 3. - Whether you are an advanced meditator or a beginner, the benefits are tremendous and will allow you to tap into your highest state of conscious functioning if you stick around long enough. 4. - Find only friends that align with who you are, your beliefs, and your values – they will make you more conscious. 5. – If you have the intention to raise your consciousness and state of awareness, you are on the right track. 6. 7. 8. 9. 10. - There are many ways to become more intelligent.

This new brain map shows almost 100 areas never described before You don’t have to be a neurosurgeon to know it’s hard to get to the right place without a good map. But neuroscientists have been blundering around with blurry brain maps, which sometimes aren’t very detailed, or omit important functions. That’s why a new map is so exciting — it shows nearly 100 areas that hadn’t been reported before. The map, described in a study published today in Nature, is a detailed look at the part of the brain that handles all your senses, as well as your motion — plus some other functions like problem solving and emotional regulation. It’s called the cerebral cortex, and it’s the brain’s outer layer of nerve tissue. "To understand the brain and to fix it, we really need to know the circuit diagram and all the parts, how they work and how they interact," says McCormick, who did not take part in the study. Matthew F. Putting together all that data helped identify these new areas. The interpretation of fMRI data has also been called into question in other studies.

Online papers on consciousness Search tips There are three kinds of search you can perform: All fields This mode searches for entries containing all the entered words in their title, author, date, comment field, or in any of many other fields showing on OPC pages. Surname This mode searches for entries containing the text string you entered in their author field. Advanced This mode differs from the all fields mode in two respects. Note that short and / or common words are ignored by the search engine.

Scientific evidence for survival of consciousness after death According to Wikipedia.org, "psychometry" is a psychic ability in which the user is able to relate details about the past condition of an object or area, usually by being in close contact with it. The user could allegedly, for example, give police precise details about a murder or other violent crime if they were at the crime scene or were holding the weapon used. About.com's Paranormal Phenomena website lists information about several of the most convincing psychometrists. Stefan Ossowiecki, a Russian-born psychic, is one of the most famous psychometrists. Ossowiecki claimed to be able to see people's auras and to move objects through psychokinesis. In later experiments, Ossowiecki performed remarkable psychometric feats with archeological objects - a kind of psychic archeology. Ossowiecki described his visions as being like a motion picture that he could watch, pause, rewind and fast-forward - like a videotape or DVD.

What my grandmother has taught me about lifelong learning Anna Ashton is my 64-year-old grandmother. She’s also a felt maker, musician, welder, milliner, builder, architect, seamstress, woodworker, artist, potter and a rather serious cyclist. Stubborn to a fault, I grew up watching her repeatedly find a challenge, put her mind to it and overcome it in new imaginative ways. She’s never stopped hunting for answers to problems, and I doubt she ever will. Anna moved from Edinburgh to Melbourne with her family at 10 years old, and one of her first triumphs was mastering an Aussie accent (until she starts hanging around with other Scots and the lilt returns). She and my grandfather Philip have had their fair share of grand adventures, cycling around the UK and kayaking to Turkey (all after hitting 50), as well as raising three children and designing and building their own beautiful three-storey house. In Anna’s eyes, learning has never had anything to do with expensive pieces of paper and qualifications. Anna and Philip, hams at large.
