El cerebro recuerda mejor dónde encontrar bizcochos que tomates cherry
La memoria espacial de los humanos retiene la ubicación de los alimentos ricos en calorías […]
Algo huele a podrido en Islandia, pero ¿por qué ciertas personas no lo notan?
Lejos de ser un capricho, la preferencia o aversión a ciertos aromas está codificada en el material genético. Un equipo de científicos islandeses descubrió que las personas con una variante en un gen encuentran el olor a pescado putrefacto menos […]
Power games may make animals smarter
New theory adds missing piece to puzzle of brain evolution. […]
Reasons Revealed for the Brain’s Elastic Sense of Time
New research finds that the subjective experience of time is linked to learning, thwarted expectations and neural fatigue. […]
Electric shocks to the tongue can quiet chronic ringing ears
Tinnitus—a constant ringing or buzzing in the ears that affects about 15% of people—is difficult to understand and even harder to treat. Now, scientists have shown shocking the tongue—combined with a carefully designed sound program—can reduce symptoms of the disorder, […]
Newfound brain structure explains why some birds are so smart—and maybe even self-aware
Never before has “bird brain” been such a compliment: In recent years, birds have been found to make tools, understand abstract concepts, and even recognize paintings by Monet and Picasso. But their lack of a neocortex—the area of the mammalian […]
Detectar la neurodegeneración temprana a través de los ojos
La presencia de unas proteínas asociadas a la muerte neuronal en el globo ocular podría predecir el desarrollo de la demencia. […]
Brain Circuitry for Fear and Anxiety Is the Same on fMRI
A study in people fails to detect differences in the brain’s response to fear or anxiety, long thought to be controlled by different neural circuits. […]
Kanabinoideek glukosaren metabolismoan duten eraginaren ondorioz, apaldu egiten dute elkarrekintza soziala
Astrozitoek odol-emaritik glukosa hartzen dute, garunari energia emateko. Aldi berean, astrozitoak neuronen kontrolpean daude, neurotransmisoreen bidez. Kontrol horretan, beste elementu batzuk ere eragiten dute; adibidez, astrozitoen hartzaileetako batzuk (1. motako kanabidoideen hartzaileak edo CB1) kalamuaren osagai psikoaktiboaren (THC) itu nagusia […]
Brain-scanning backpack brings neuroscience into the real world
Call it neuroscience on the go. Scientists have developed a backpack that tracks and stimulates brain activity as people go about their daily lives. The advance could allow researchers to get a sense of how the brain works outside of […]
