Forgetting is essential to the smooth running of the brain

from Marie-Céline Jacquier, read full article in french on Futura Sciences

Forgetting is an essential element in the human intelligence because it allows to concentrate on what is important. An effective memory does not design as an accumulation of data: the preservation of too precise information can indeed become counterproductive.

That is said by two researchers of the university of Toronto in a new article appeared in Neuron, where they draw up a parallel between the human memory and the artificial recollection. […] According to the authors, the objective of the memory is not to pass on the most faithful information, but rather to optimize the decision-making by preserving only those of value. […] Forgetting allows to adapt oneself to new situations by leaving aside dated and misleading information which are not necessarily useful in an environment that has changed.



Your environment makes you stupid



Hello everybody! I have lots of different products for you today: cosmetics, paint, cans, furniture, plastic toys… And what’s the similarity between all these objects? That they contain endocrine disruptors1.


The endocrine disruptors that fulfil your everyday life environment not only have an effect on your physical health, but also on your mental health. And on the society.

We all have already heard about endocrine disruptors, we all know that these products are harmful for human beings, that men synthesizes them in large quantities and that they are largely spread in our environment. But we less often hear about the disastrous sanitary consequences – at a society scale – caused by this established fact. Although you don’t need to be brilliant to understand that high concentration of toxic products in the environment means global health issues for the population, the idea that the disease is not a particular case, on the individual scale, that it is not an accident, is hard to conceive. And that’s for sure because this almost never happened during the human kind’s history! Nevertheless, how couldn’t it be in the present context?

I recently read an article2 the concept of which interested me: because it handled the global, societal consequences of the endocrine disruptors issues, more than their effects on the individual human body, and also because it estimated the financial (!) cost of this issue for the society. So, the circle is completed: this article touches the junction between the environmental discourse and the financial one. An industrial solution destroying men (and nature) necessarily fights against its own topic (the search fot financial profit). What is the kind of a solution which result is counterproductive even towards the only objective it is supposed to achieve – to the detriment of all the other components of the problem – if not a bad one?


Let’s go for the heart of the subject: in March, 2015, a research team led by Leonardo Trasande from New York University School of Medicine showed that the annual cost of the consequences of the endocrine disruptors issues amounts to 157 billion euros a year (that is 1,28 % of the GDP) on the European Union extent. Their results are published on the website of the “Newspaper of Clinical Endocrinology and Metabolism”. These costs are imputed to the means devoted to take care of the population affected by these products, the consequences

of which are, in bulk: cases of infantile backwardness, autism, attention deficit hyperactivity disorder for the intellectual consequences, diabetes, obesity and … assisted reproductive technologies (certain endocrine disruptors have reprotoxic effects) for the physical ones3.


In the end, we only can recommend to you to pay attention on what you buy, from the products of which you spread your body (shower gels, cosmetics) up to your food and their packaging. Thus, read the compositions of the products you buy and use, for the sake of your body, your mind and the society!

Depression: what if it was the thyroid?


Article in french magazine « Alternative Santé »



” The depression is not a disease “, explains Dr Brogan, psychiatrist and practitioner in integrative holistic medicine in New York. ” It is the sign of an imbalance in the body, that must be simply restored. ” The real underlying physiological cause of the depression, the faintness, the anxiety, the reduction in libido, and the fatigue of a woman is far from being only situated in the brain. Very often, the exact cause is not diagnosed and untreated: only the symptom is masked, often with massive amount of antidepressants.

The neurologist Joseph Coyle for example, of Harvard Medical School, declared in 2014: ” the chemical imbalance is a kind of thought of the last century. It is much more complicated than that. It is not because these symptoms were caused by a chemical kind of problem, that the medicine is capable of correcting it. ” The author adds, sarcastic: ” the aspirin lessens headaches, but headaches are not caused by a deficiency in aspirin. “
