neural correlates I: introduction and examples

Molte persone al mondo, spesso motivate da giornali troppo zelanti, pensano che i neuroscienziati siano quasi arrivati ad una comprensione della mente umana. Cosa vorrebbe dire comprensione? Una buona definizione mi pare: "Essere in grado to explain the most basic level possible, how and why a human being behaving in a certain way. "It is quite clear that to answer such a question is necessary to know beforehand what happens in the brain of a person (since we we believe the brain be the implementation of the mind) when it behaves in a certain way. Know, then, that this question is largely unanswered. But the answer, if there were, would have a fancy name: the neural correlates . A special role has obviously neural correlates of consciousness.

some examples of what I would like to know the level of neurons. As we explained several times, neurons are cells whose activity is expressed through brief electric shock. We know with certainty that: there are perceptions and actions that have increased activity as a neural correlate of some neurons, there are perceptions and actions that have decreased as a correlate neural activity of some neurons, neurons correlating with the same class of representation (shape, color, smell, movement) are easy to find similar in nearby areas of the brain are related to the activity are not increased or decreased. Let me give you some examples:

increased activity

You will not notice it, but you continually move the fixation point of your eye. Before each micromotion, there are some neurons that are activated.

activity decreased

Some neurons are more active when an object is in a fairly precise in your field of vision, but less active than usual if the object is located nearby. Read more.

Zone

neurons that correlate with the direction of movement are all in a particular area of \u200b\u200bthe visual cortex. Moving a few micrometers, the class of correlation changes. Related

different

There are neurons that increase their activity only slightly just before a motor signal, while the legality of their activities will be much more. This concerns the

thing. Obviously, knowing how these representations are manipulated is still very, very, very beyond come. You know if you can reduce the mind to its neural correlates is a question likely to remain forever unanswered.
