Careless Head

Nasrudin was tying his turban when the wind caught the cloth and carried it away. ‘What a shame!’ lamented his friend. ‘That was a beautiful piece of Indian muslin.’ ‘I should never have trusted my careless head with it. That is the third turban it has lost this week,’ said Nasrudin.

How listening to music ‘significantly impairs’ creativity


Summary: The popular view that music enhances creativity has been challenged by researchers who say it has the opposite effect. Psychologists investigated the impact of background music on performance by presenting people with verbal insight problems that are believed to tap creativity. They found that background music ‘significantly impaired’ people’s ability to complete tasks testing verbal creativity — but there was no effect for background library noise.

Mother’s Behavioral Corrections Tune Infant’s Brain to Angry Tone

 

The same brain network that adults use when they hear angry vocalizations is at work in infants as young as six months old, an effect that is strongest in infants whose mothers spend the most time controlling their behavior, according to a new study in the open-access journal PLOS ONE by Chen Zhao of the University of Manchester, UK, and colleagues. The study indicates that the network recruited in adult vocal emotion processing is up and running quite early in life, and that its sensitivity to anger is partly a result of maternal interactions.

Not all sleep is equal when it comes to cleaning the brain

New research shows how the depth of sleep can impact our brain’s ability to efficiently wash away waste and toxic proteins. Because sleep often becomes increasingly lighter and more disrupted as we become older, the study reinforces and potentially explains the links between aging, sleep deprivation, and heightened risk for Alzheimer’s disease.

“Sleep is critical to the function of the brain’s waste removal system and this study shows that the deeper the sleep the better,” said Maiken Nedergaard, M.D., D.M.Sc., co-director of the Center for Translational Neuromedicine at the University of Rochester Medical Center (URMC) and lead author of the study. “These findings also add to the increasingly clear evidence that quality of sleep or sleep deprivation can predict the onset of Alzheimer’s and dementia.”

The study, which appears in the journal Science Advances, indicates that the slow and steady brain and cardiopulmonary activity associated with deep non-REM sleep are optimal for the function of the glymphatic system, the brain’s unique process of removing waste. The findings may also explain why some forms of anesthesia can lead to cognitive impairment in older adults.

El Cuento de Hatim

 

La honestidad no es, por supuesto, fácil: porque la verdadera honestidad se ejercita sin dificultad cuando es la manifestación de una realidad interior, no cuando es un deber o una dificultad. Pero para ilustrar la actividad de un hombre o una mujer honestos pueden utilizarse ciertos principios.

EL CUENTO DE HATIM

Cuando Hatim al-Asamm de Balkh (ahora en Afganistán) fue a Bagdad, la gente lo rodeó, diciendo:

“Eres un no árabe de hablar vacilante, y sin embargo silencias a todos”.
Él respondió: “Hay tres cosas que me permiten vencer a mi oponente. Estoy feliz cuando tiene razón, estoy triste cuando se equivoca, y trato de no comportarme tontamente con él”.
