Emotions ... in our brains through our body and immaterial?
Much research exploring the link between certain brain structures (including the amygdala) and emotions. New neuroimaging techniques (including the
fMRI) produce results that require us to rethink, among others - the question of the seat of emotions. They reveal how some areas are activated when emotions occur, including the amygdala (The hippocampus and amygdala (not those at the bottom of the gorge, which is at the center of the brain ...).

Biologists are probably inclined to believe that one day we can explain emotions in terms of neuronal activity in the brain's complex system without necessarily having seriously challenged assumptions. The literary and philosophical than I could cross disbelieve that science may one day explain the emotions and cry reductionism, sometimes without really bothered to understand these new studies.
So the question of body and mind arises in a new way: 
Emotions Are the manifestation of the activity nerve centers that begins to identify more precisely, or are they more noble and do not they reduce to a simple hardware support ... As the sheet of paper is necessary to the poet, but Creativity is not his? The movement of the pen appear every time you see a poem should not conclude that poetry is born in the pen or hand! Yet much research supports more firmly a neurological basis for emotions! Both positions are they necessarily irreconcilable? there any intermediate positions, or way out of this alternative ?
On 4 February, four senior specialists will share their views: a rare chance to have such different perspectives but all high-level meeting to discuss!
Purves (2001) To be able to make informed judgments about publications, to answer questions from students.
Or just to have fun listening to a stimulating debate! Since it remains
space in the room, I take the initiative to say that the day is open to all!
| Description of functional MRI techniques, discussion of their limitations using examples in the field of emotions, decision making of the face and voice recognition and attachment. - Psychoanalytic Insight report on the body / mind in the emotions. - Neurobiology: the biological perspective on the examples cited. - Lighting philosophical: the relation between body and mind. - Debate and confrontation of perspectives. To be part of continuing education OP-10401 or contact E. Scheidegger here Two examples of recent research supporting the idea instead of a neurological basis for emotions: Of everything I have chosen two examples published lately, not directly related fMRI, as it will be presented on February 4 but which are accessible and beautiful open questions. And you'll want to attend the day? Both speak of the amygdala, a bilateral structure the size of two kernels (hence its name amygdala) For more information on the amygdala: cf Purves here |
- which is singular
even if it is bilateral said Ivan Rodriguez - in the nervous system (it is part of the limbic system) and not the tonsils the back of the throat (secondary immune organ)! The amygdala was greater for more social beings? How many friends you could be predicted by the size of the tonsil (See fig 1) found in a wide range of vertebrates, reports

Bickart, KC, et al. (2010) compared the size of this structure (See fig. 1) in 58 healthy adults and asked them how many friends they had and how many groups they belonged. Participants who had a social network larger and more complex had the tonsil (s) larger (s) see Fig 3.

The nature of this relationship-volume social network remains mysterious to the authors. Perhaps the well-known role of this structure in face recognition, emotions and emotional memory effect that one develops and maintains relationships said one of the authors. We know that correlation is not causality! It is possible that this is the opposite: the size of the amygdala would be the result of a complex social network and not the cause. Kevin Ochsner, Columbia University in New York said it could even be both at once (sociability increased the size of the amygdala, which allows more sociability which increases the size, ...). It also considers the strength of evidence for this article will make it a classic.
A woman without fear and amygdala ... A woman of 44 years - out of respect for her anonymity authors call SM - has been studied extensively: she fears nothing, not snakes or spiders, or horror movies. She sees no fear in the faces of others, his eyes not looking at the face and signs of emotion as the others. Adolphs, R., et al. (2005) see cons below:

This case reinforces the thesis that emotions are the result of the interaction of these neurons in various parts of the brain and the amygdala plays a crucial role. Fig 6: The dual circuit of emotions . (source:
Dubuc, Bruno (2008). , More specifically, it reinforces the idea dear to Damasio, one of the authors, that emotions are bodily symptoms under control of the amygdala, in fact, directly produced by the stimuli which we realize. In this view, emotions are the accelerating pulse, sweating, dry throat, ... and then we would realize our emotions through the body.

That there are people much more knowledgeable than others is not very intriguing. What is extraordinary, and devilishly instructive is how two people with close acquaintances may differ in how they interpret them. Placed, as to know, about the same point they observe worlds that seem to have nothing in common irreducibilities Such interpretations are more rewarding than the differences in areas of knowledge.

An author
not wiser than his readers but which includes know in a way that surprised the dumbfounded and even shocking, gives them an author who has more to offer than their larger knowledge that theirs. If you're left, read the right authors, if you are rational, read mystical (and symmetrically, course)! Stimulation of the disagreement arises. Nobody knows what they think when we understand the reasons of those who think otherwise.
take advantage of this special day to take the measure of a fascinating debate that is sure to appear in class!
