Cannabis: Insomnia Twice as Common Among Students Who Use It Every Day
The likelihood of suffering from insomnia was found to be 45% higher in cannabis users compared to non-users. In France, over half of students suffer from sleep complaints. These are particularly concerning as they can affect the success of their studies, and their physical and mental health. A real public health issue, the evaluation of these health risks is one of the research subjects of a team of scientists from Inserm, Université de Bordeaux and Bordeaux University Hospital.

A blood factor involved in depression
A small group of neural stem cells isolated from mice and cultured in vitro observed under a confocal microscope. The process of aging is often related to the onset of cognitive decline, depression and memory loss. Scientists from the Institut Pasteur, CNRS and Inserm have discovered that administration of the GDF11 protein, which is known to regenerate murine neural stem cells, improves cognitive abilities and reduces the depressive state in aged mice.

Predicting the Onset of Anxiety Disorders in Adolescence Thanks to Artificial Intelligence
Anxiety disorders are the most common psychiatric conditions in adolescence, with nearly one in three individuals affected. Adobe Stock Anxiety disorders are the most common psychiatric conditions in adolescence, with nearly one in three individuals affected. Some of these disorders - such as panic disorder or generalized anxiety disorder - tend to emerge slightly later in life or consolidate in early adulthood.

Fathers Who Take 2 Weeks Paternity Leave Are Considered Less Likely to Develop Postpartum Depression
Fathers Who Take 2 Weeks Paternity Leave Are Considered Less Likely to Develop Postpartum Depression
Omar Lopez sur Unsplash In the weeks that follow the birth of a child, both parents are likely to develop depression. Paternity leave, recognized for its benefits on family balance, child development and male-female equality, could be one of the keys to preventing this condition that affects one in ten fathers and almost two in ten mothers.

Preventing dementia in seniors: meditation still under investigation
Meditation as a tool to prevent dementia and improve the mental health and well-being of elderly people is one of the avenues explored by the European Medit-Ageing research program, coordinated by Inserm. As part of this program, researchers from Inserm and Université de Caen Normandie, in collaboration with French and European teams, observed the impact of 18 months of meditation training on certain brain structures involved in regulating attention and emotions in healthy people over 65.

Questioning the universal application of neurocognitive tests
Questioning the universal application of neurocognitive tests
Human interactions are enabled by a set of neurocognitive mechanisms defined by the notion of social cognition. In order to detect patients with social cognition disorders, specialists use internationally validated evaluation tests. However, most of these tests have been developed in industrialized Western countries, which raises questions about the relevance of generalizing them to the whole of humanity.

Questioning the Universal Application of Neurocognitive Tests
Human interactions are enabled by a set of neurocognitive mechanisms defined by the concept of "social cognition”. In order to identify social cognition disorders, specialists use internationally validated evaluation tests. However, these are most often developed in western, industrialized countries, which could question the relevance of applying them to all humanity.

Do Some Cognitive Biases Contaminate Even Our Simplest Mental Mechanisms?
When we implement complex cognitive processes, for example when making decisions, we are subject to cognitive bias. But what about simpler processes, such as those involved in the most basic learning? In a new study analyzing data from all previous research in the field, researchers from Inserm and ENS-PSL show that not only are positivity and confirmation biases present even in the simplest human and animal cognitive processes, but also that incorporating them into learning algorithms would enhance their performance.

New Brain Abnormalities Associated with Child Abuse
New Brain Abnormalities Associated with Child Abuse
In collaboration with a Canadian team, scientists from Inserm and Université de Tours, at Unit 1253 Imaging & Brain1, have shown in post-mortem brain samples that victims of child abuse present specific brain characteristics. The teams have revealed for the first time in humans an increase in the number and maturation of perineuronal nets, dense protein structures surrounding the neurons.

Memory : recognizing images seen briefly ten years previously
Recalling the names of old classmates 50 years after graduation or of favorite childhood television series illustrates the amazing abilities of human memory. Emotion and repeated exposure are both known to play a role in long-term memorization, but why do we remember things that are not emotionally charged and have only been seen or experienced a few times in the past?

Interaction Between Brain and Heart May be New Indicator of State of Consciousness
How do we know whether a patient is conscious when he or she is unable to communicate? According to an Inserm study conducted in 127 patients aged 17 to 80, changes in heartbeat in response to sound stimulation is a good indicator of state of consciousness. This is what Inserm researcher Jacobo Sitt and his team, based at the Brain & Spine Institute (ICM) at Pitié-Salpêtrière Hospital, AP-HP, demonstrate in an article published in Annals of neurology.

Prenatal exposure to endocrine disruptors and behavioral problems in children
An epidemiological study carried out by Inserm on families from the EDEN cohort (500 boys born between 2003 and 2006 and their mothers) shows that exposure during pregnancy to certain phenols and phthalates is associated with behavioral problems in boys between 3 and 5 years of age. The most worrying compounds in this respect are bisphenol A, triclosan and dibutyl phthalate (DBP).

What the pupils tells us about language
What the pupils tells us about language
The meaning of a word is enough to trigger a reaction in our pupil: when we read or hear a word with a meaning associated with luminosity (“sun,” “shine,” etc.), our pupils contract as they would if they were actually exposed to greater luminosity. And the opposite occurs with a word associated with darkness (“night,” “gloom,” etc.

Toxoplasmosis: morbid attraction to leopards in parasitized chimpanzees
Researchers from the Centre d'Écologie Fonctionnelle et Évolutive (CNRS/Université de Montpellier/Université Paul Valéry Montpellier 3/EPHE) have shown that chimpanzees infected with toxoplasmosis are attracted by the urine of their natural predators, leopards, but not by urine from other large felines.
