La inteligencia y el vuelo han permitido a los cuervos colonizar el mundo
La capacidad de volar largas distancias, un cuerpo grande y la inteligencia para resolver problemas y obtener recursos en nuevos ambientes han sido una combinación perfecta que ha hecho posible que estas aves se hayan propagado. Así lo afirma un estudio del CREAF y la Universidad de Washington en St. Louis (EE UU) que ha comprobado que la expansión global de los cuervos ha producido una enorme diversificación de más de 40 especies en 10 millones de años.

AI Overcomes Stumbling Block on Brain-Inspired Hardware
Algorithms that use the brain’s communication signal can now work on analog neuromorphic chips, which closely mimic our energy-efficient brains.

New Map of Meaning in the Brain Changes Ideas About Memory
Researchers have mapped hundreds of semantic categories to the tiny bits of the cortex that represent them in our thoughts and perceptions. What they discovered might change our view of memory.

Ultrasound to Control Neurons in Mice
A study shows “sonogenetics” could be a useful new tool in neuroscience and other fields.

Musikaz gozatzeko ezgaitasuna: anhedonia musikala
Musika entzutea, piezaren, unearen eta entzulearen arabera, izan daiteke hunkigarria, dantzagarria, gozagarria, mingarria, iradokitzailea… Gutxi batzuentzat, ordea, ez da ezer; ez die ezer eragiten. Ez sentipenik, ez emoziorik, ez erantzun neurologiko zein fisiologikorik: anhedonia musikala dute. Berezitasun horren oinarriak eta ondorioak ikertu dituzte, besteak beste, Noelia Martínez-Molina neurozientzialariak eta María García-Rodríguez musika-terapeutak.

The Brain Doesn’t Think the Way You Think It Does
Familiar categories of mental functions such as perception, memory and attention reflect our experience of ourselves, but they are misleading about how the brain works. More revealing approaches are emerging.

Two Previously Unknown Brain Cell Types Have Been Discovered in Mouse Study
Despite us having mapped and categorized so much of mammal biology already, there are still new surprises lying in wait. Now, scientists have found two new types of glia – a type of support cell – in mouse brains.

Diferencias cerebrales en los niños obesos
Las alteraciones en el sistema de recompensa del cerebro se asemejan a las que presentan las personas con un trastorno obsesivo-compulsivo.

How did Neanderthals and other ancient humans learn to count?
Archaeological finds suggest that people developed numbers tens of thousands of years ago. Scholars are now exploring the first detailed hypotheses about this life-changing invention.

Reduced Adult Neurogenesis Linked with Alzheimer’s Disease
Manipulating the production of new neurons can improve cognition in animal models of the disease, raising the possibility that figuring out a way for humans to make more neurons could make a difference for people with dementia.
