10 Things That Will Make You Happier, Backed By Science. I would love to be happier, as I’m sure most people would, so I thought it would be interesting to find some ways to become a happier person that are actually backed up by science.
Here are ten of the best ones I found. 1. Exercise more – 7 minutes might be enough You might have seen some talk recently about the scientific 7 minute workout mentioned in The New York Times. So if you thought exercise was something you didn’t have time for, maybe you can fit it in after all. Exercise has such a profound effect on our happiness and well-being that it’s actually been proven to be an effective strategy for overcoming depression. The groups were then tested six months later to assess their relapse rate. You don’t have to be depressed to gain benefit from exercise, though. A study in the Journal of Health Psychology found that people who exercised felt better about their bodies, even when they saw no physical changes: 2. 3. 4.

Protein interactions underlie the complexity of neuronal function.
Potential interactions between specific proteins in the brain are predicted from assays based on genetic interaction and/or biochemistry. Genetic interaction reveals endogenous, but not necessarily direct, interactions between the proteins. Biochemistry-based assays, on the other hand, demonstrate direct interactions between proteins, but often outside their native environment or without a subcellular context. We aimed to achieve the best of both approaches by visualizing protein interaction directly within the brain of a live animal. Here, we show a proof-of-principle experiment in which the Cdc42 GTPase associates with its alleged partner WASp within neurons during the time and space that coincide with the newly developing CNS.

Savez-vous pourquoi et comment vous dormez ? Savez-vous combien de temps chaque nuit vous dormez profondément, vous rêvez, à quel moments et pourquoi vous vous agitez, à quel rythme se produisent vos alternances de sommeil lent et de sommeil paradoxal, pourquoi au moment de vous endormir, vous avez froid, et vous vous réveillez en ayant chaud, pourquoi le "coup de pompe" de onze heures du matin, ou l'envie de sieste de début d'après-midi ? Seriez-vous capables de dire de combien d'heures de sommeil vous avez besoin pour être en forme, et à combien de cycles nocturnes, et surtout à des cycles de quelle durée cela correspond ? Quelle est votre heure "naturelle", physiologique, d'endormissement et quels en sont les signes d'approche ?

Brain-scanning technology and cognitive tests on a variety of subjects by one of the world’s foremost cognitive neuroscientists has led to a better understanding of how a region of the brain responds to visual stimuli. The results could profoundly affect learning and help individuals with reading disabilities Although I find the diversity of the world’s writing systems bewildering, there is a striking regularity that remains hidden.

Key concepts Animals Predators Prey Camouflage Introduction Have you ever wondered how predators such as wolves, lions and hawks are able to find their prey?
And what can an animal do to keep from being a predator's dinner? To survive, some animals use camouflage so they can better blend in with their surroundings. In this science activity you'll be the hungry predator and you'll hunt for different colored candies. But it may not be as easy as it sounds—some of your prey will be camouflaged by their habitats. Background Nature can be brutal. A common way that animals can avoid being eaten by a predator is by using an adaptation called camouflage, which is a set of colorings or markings on an animal that help it to blend in with its surroundings, or habitat, and prevent it from being recognized as potential prey. Preparation • Count and place 10 M&Ms of each color into a plastic bag.

Conclusions publiées dans le Journal of Cognitive Neuroscience. Lève-tôt et couche-tard diffèrent dans leurs attitudes par rapport au présent et au futur. La préférence à être lève-tôt ou couche-tard, appelée chronotype, est liée à différentes orientations et attitudes par rapport au présent et au futur (perspectives temporelles), selon une étude publiée dans la revue Biological Rhythm Research. Les gens du matin ont tendance à se réveiller et se coucher tôt et à être plus productifs en début de journée. Ceux du soir ont tendance à se réveiller plus tard, à démarrer plus lentement et à être à leur meilleur dans la soirée. La plupart des gens se situent entre les deux. Alors que des facteurs biologiques et génétiques peuvent être en cause, la présente étude met en évidence un facteur psychologique. Tout savoir sur les différents types de mémoire.

Changes in Sensitivity of Reward and Motor Behavior to Dopaminergic, Glutamatergic, and Cholinergic Drugs in a Mouse Model of Fragile X Syndrome.
Fragile X syndrome (FXS) is a leading cause of intellectual disability. FXS is caused by loss of function of the FMR1 gene, and mice in which Fmr1 has been inactivated have been used extensively as a preclinical model for FXS. We investigated the behavioral pharmacology of drugs acting through dopaminergic, glutamatergic, and cholinergic systems in fragile X (Fmr1-/Y) mice with intracranial self-stimulation (ICSS) and locomotor activity measurements. We also measured brain expression of tyrosine hydroxylase (TH), the rate-limiting enzyme in dopamine biosynthesis. Fmr1-/Y mice were more sensitive than wild type mice to the rewarding effects of cocaine, but less sensitive to its locomotor stimulating effects. Anhedonic but not motor depressant effects of the atypical neuroleptic, aripiprazole, were reduced in Fmr1-/Y mice.

Epilepsy opens a new window into brain function. Arguably one of the greatest contributions to modern day neuroscience was made in 1953 by Henry Molaison, a 27-year-old man who suffered from debilitating epilepsy.
The summer of that year, a surgeon in Hartford, Conn., removed two slivers of Molaison's brain, an attempt to quell the seizures. The seizures subsided, but Molaison was left lacking the ability to record new memories, a case of severe anterograde amnesia that revolutionized our understanding of how memory works and helped establish the science of it.
Epilepsy and patients like Molaison have frequently been at the center of breakthroughs in understanding the mysteries of the brain.

Early success in new treatment for stroke recovery. Researchers at The University of Texas at Dallas have taken a step toward developing a new treatment to aid the recovery of limb function after strokes. In a study published online in the journal Neurobiology of Disease, researchers report the full recovery of forelimb strength in animals receiving vagus nerve stimulation. "Stroke is a leading cause of disability worldwide," said Dr. Navid Khodaparast, a postdoctoral researcher in the School of Behavioral and Brain Sciences and lead author of the study. "Every 40 seconds, someone in the U.S. has a stroke. Researchers identify the neural circuits that modulate REM sleep.
A team of scientists led by Dr. Antoine Adamantidis, a researcher at the Douglas Mental Health University Institute and an assistant professor at McGill University, has released the findings from their latest study, which will appear in the October issue of the scientific journal Nature Neuroscience. Previous studies had established an association between the activity of certain types of neurons and the phase of sleep known as REM (rapid eye movement). Researchers on the team of Dr. Antoine Adamantidis identified, for the first time, a precise causal link between neuronal activity in the lateral hypothalamus (LH) and the state of REM sleep.

Online time can hobble brain's important work. While you are browsing online, you could be squandering memories -- or losing important information. Contrary to common wisdom, an idle brain is in fact doing important work -- and in the age of constant information overload, it's a good idea to go offline on a regular basis, says a researcher from Stockholm's KTH Royal Institute of Technology. Erik Fransén, whose research focuses on short-term memory and ways to treat diseased neurons, says that a brain exposed to a typical session of social media browsing can easily become hobbled by information overload.
