Déclaration de conscience des animaux Bien que cela puisse ne pas sembler beaucoup pour les scientifiques de déclarer que de nombreux animaux non humains possèdent un état de conscience, c'est la première reconnaissance officielle. L'ensemble des preuves scientifiques de plus en plus importante montre que la plupart des animaux sont conscients de ce qu'ils font, de ce qu'ils sont par rapport à l'autre. De la même manière que nous le sommes et nous le faisons. Ce qui est aussi intéressant à propos de cette reconnaissance de la conscience, c'est qu'il est maintenant admis que ce degré de conscience peut émerger chez les animaux qui sont très différent de l'homme, à savoir les oiseaux (la pie par exemple qui est considérer comme un animal nuisible en France) et certains céphalopodes. Le chien agit t-il uniquement par imitation ou conscience de soi ? L'une des caractéristiques de l'auto-organisation des systèmes est que le système est toujours plus intelligent que la somme de ses parties. Partager:

Composing Your Thoughts - Issue 2: Uncertainty 1. Unshaven and one bit short To death and taxes, Benjamin Franklin’s binary list of life’s certainties, add the expectation that this six-note sequence: Will continue with this: Although we ponder ways to avoid or evade Franklin’s list of unavoidable events, we generally accept this more benign certainty as immutable. The penultimate note of the tune generates such strong and specific anticipation that you are likely finding it difficult to continue reading without resolving the sequence. The ubiquitous “Shave and a Haircut” and its aborted variant provide ideal stimuli to study how the brain responds to violated expectations. 2. Contrary to the proverbial tree-falling-in-the forest quandary, a musical note that fails to materialize is at least as present in our brain as it would be had it actually sounded. In the 1970s, psychologists Robert Rescorla and Allan R. I have shown that effect in my own studies at Stanford University’s Center for Computer Research in Music and Acoustics. 3.

Déclaration de Cambridge sur la conscience La Déclaration de Cambridge sur la conscience a été rédigée par Philip Low et révisée par Jaak Panksepp, Diana Reiss, David Edelman, Bruno Van Swinderen, Philip Low et Christof Koch. La Déclaration a été proclamée publiquement à Cambridge (Royaume-Uni) le 7 juillet 2012 lors de la Francis Crick Memorial Conference on Consciousness in Human and non-Human Animals, au Churchill College de l’Université de Cambridge, par Low, Edelman, et Koch. La Déclaration a été signée par les participants à ce colloque le soir-même, en présence de Stephen Hawking, dans la Salle Balfour de l’Hôtel du Vin de Cambridge. La cérémonie de signature a été filmée par CBS 60 Minutes. Le champ des recherches sur la conscience évolue rapidement. Nous faisons la déclaration suivante : « L’absence de néocortex ne semble pas empêcher un organisme d’éprouver des états affectifs.

Endogenous opioids The physiologic modulation of noxious stimuli involves a highly complex system that integrates the actions of multiple opioid receptors and endogenous opioid peptides. Endogenous opioid peptides Opioid peptides that are produced in the body include: - Endorphins - Enkephalins - Dynorphins - Endomorphins Each family derives from a distinct precursor protein and has a characteristic anatomical distribution. The precursors, prepro-opiomelanocortin (POMC), preproenkephalin and preprodynorphin which are encoded by three corresponding genes code for the endorphins, enkephalins, and dynorphins respectively. Each precursor is subject to complex cleavages and post-translational modifications resulting in the synthesis of multiple active peptides. Following the biochemical purification and characterization of the three endogenous opioid peptide families much progress has been made in mapping the specific locations of opioid peptides and their binding site distributions throughout the brain.

The 6 Most Mind-Blowing Animal Senses You probably already know that when it comes to everything but intellectual pursuits and wearing cardigans in a knot over one's shoulders, animals have humans beat. All of your senses together can't match what a dog can pick up with its nose, for instance. But every now and then, an animal's sensory superiority goes above and beyond the usual and takes a turn for the bizarre and/or terrifying. #6. Wikipedia Vampire bats are the only mammals that subsist entirely on blood -- otherwise, we'd just call them "bats." Livescience.comBats only appear on film as 1980s school photos. That nose that God forgot actually does more than just invite business cards of bat plastic surgeons -- it can sense the heat of your blood flowing through your veins. Its nose-lip combo contains infrared heat cells that can sense the warmth of the blood at a distance.

More Left Brain / Right Brain Nonsense This is one of those memes that refuses to die. It’s a zombie-meme, the terminator of myths, one of those ideas of popular culture that everyone knows but is simply wrong – the idea that individuals can be categorized as either left-brain or right-brain in terms of their personality and the way they process information. Related to this is the notion that any individual can either engage their left brain or their right brain in a particular task. The most pernicious myths tend to have a kernel of truth, but are misleading or oversimplified in a significant way. For example, language function lateralizes to the dominant hemisphere, which is the left hemisphere for most people. That is as far as the left-brain/right-brain popular belief goes. In order to see each hemisphere operating on it’s own you need to specifically create a situation in which they do not communicate. I recently encountered two instances of the left-brain/right-brain myth, prompting this post.

Rubber Hand Trick Reveals Brain-Body Link | Wired Science The rubber hand illusion is more than a vaguely creepy parlor trick. It’s a window into relationship between our mental and physical self-conception. During the illusion, a participant’s hand is hidden, and a rubber hand positioned so that it appears as her own. She knows that it’s fake — but when both hands are stroked simultaneously, what’s seen and felt becomes blurred. Suddenly the rubber hand literally feels like it belongs to her. Consciously she knows it’s not true, but that doesn’t matter. Scientists have now shown that the hidden hand’s temperature drops during the illusion: its effects aren’t simply mental, but physical as well, and could even hint at as-yet-unknown processes of disease. "These findings show that the conscious sense of our physical self, and the physiological regulation of our physical self, are linked," write a team of researchers led by Oxford University’s G.

Les animaux en toute conscience Darwin affirmait, il y a cent cinquante ans, qu’il n’y a pas une différence de nature mais de degré entre l’homme et les autres espèces animales. Pourtant, il y a encore quelques décennies, parler chez l’animal de conscience, c’est-à-dire des états supérieurs de l’activité intellectuelle, eût été inconcevable dans les milieux scientifiques. Il y régnait un climat de «mentaphobie» dénoncé par Donald Griffin, fondateur de l’éthologie cognitive. Ce temps semble définitivement révolu. Le néocortex n’est donc plus considéré comme indispensable pour penser finement. Notre code civil témoigne de cette chosification de l’animal, qu’il qualifie archaïquement de bien meuble (article 528) quand, en Allemagne ou en Suisse, les animaux sont expressément distingués des choses.

10 theories that explain why we dream Kinja is in read-only mode. We are working to restore service. I like #7 and #8 of sorts, as they sort of fit in with the kinds of dreams I have. Fixing things, solving thing, experimenting with situations, and learning. That said, I know that differs a lot from the kind of dreams I probably had as a child, so there really can't be a single answer to this I guess. On that note after seeing Inception I loved the comments about how our dreams are basically "filled in" with familiar places/things to make them feel more complete. Flagged

5 Mind-Blowing Ways Your Senses Lie to You Every Day #2. Your Brain Changes the Size of Objects Around You Yuliya Chsherbakova/ Your eyes are lying to you right now about something as basic as the size of the stuff you're looking at. Don't believe us? Mighty Optical IllusionsSpoiler: You're about to feel dumb. If you answered the one on the right, congratulations, you're completely normal, and also completely wrong. Mighty Optical Illusions They're the exact same size. The above photograph is an example of the Ponzo illusion, which occurs when an image's context tricks your brain into seeing size differences. QuiaPoint all you want, kid, it'll always be shorter. So where have you seen this type of illusion in real life? If you see four at the same time, though, you probably need new glasses. But here's the weirdest part: Because these illusions are based on context, how badly they fool you depends on what you're used to seeing ... meaning that city dwellers are more vulnerable to being tricked. #1.

Le statut des animaux progresse dans le code civil La commission des lois de l’Assemblée nationale a reconnu mardi aux animaux la qualité «d’être vivants doués de sensibilité», alors que jusqu’à maintenant le code civil les considérait comme «des biens meubles», selon une source parlementaire. Cette modification législative fait l’objet d’une pétition lancée il y a près de deux ans par la fondation de protection animale Trente Millions d’amis, et qui a reçu le soutien de plusieurs intellectuels. La commission a adopté un amendement socialiste en ce sens, dans le cadre d’un projet de loi de modernisation et de simplification du droit, qui sera soumis au vote dans l’hémicycle, mardi soir et mercredi. Actuellement, le code rural et le code pénal «reconnaissent, explicitement ou implicitement, les animaux comme "des êtres vivants et sensibles"» mais pas le code civil, expliquent les auteurs de l’amendement, au premier chef le député PS des Hautes-Pyrénées Jean Glavany.
