A glimpse into the workings of the baby brain

In adults, certain regions of the brain’s visual cortex respond preferentially to specific types of input, such as faces or objects — but how and when those preferences arise has long puzzled neuroscientists. One way to help answer that question … Continue reading

Exercise Increases Brain Size

Exercise increases the size of the left region of the hippocampus, an area of the brain critical for memory, a new study reveals. In a first of its kind international collaboration, researchers from Australia’s National Institute of Complementary Medicine at … Continue reading

How neurons use crowdsourcing to make decisions

How do we make decisions? Or rather, how do our neurons make decisions for us? Do individual neurons have a strong say or are the voice in the neural collective? One way to think about this question is to ask … Continue reading

How to Have a Healthy Brain and Keep It

“It’s increasingly clear that exercise is as good for the brain as it is for the body, The Globe and Mail reported. “You’ll score better on cognitive tests immediately after a moderate workout, and the gains accumulate over weeks of … Continue reading

What is a representative brain? Neuroscience meets population science

The last decades of neuroscience research have produced immense progress in the methods available to understand brain structure and function. Social, cognitive, clinical, affective, economic, communication, and developmental neurosciences have begun to map the relationships between neuro-psychological processes and behavioral … Continue reading

Networks of the Brain

Over the last decade, the study of complex networks has expanded across diverse scientific fields. Increasingly, science is concerned with the structure, behavior, and evolution of complex systems ranging from cells to ecosystems. In Networks of the Brain, Olaf Sporns … Continue reading

Brain Anatomical Network and Intelligence

Intuitively, higher intelligence might be assumed to correspond to more efficient information transfer in the brain, but no direct evidence has been reported from the perspective of brain networks. In this study, we performed extensive analyses to test the hypothesis … Continue reading

Predictive brains, situated agents, and the future of cognitive science

Brains, it has recently been argued, are essentially prediction machines. They are bundles of cells that support perception and action by constantly attempting to match incoming sensory inputs with top-down expectations or predictions. This is achieved using a hierarchical generative model that … Continue reading

The social and cultural roots of whale and dolphin brains

Encephalization, or brain expansion, underpins humans’ sophisticated social cognition, including language, joint attention, shared goals, teaching, consensus decision-making and empathy. These abilities promote and stabilize cooperative social inter-actions, and have allowed us to create a ‘cognitive’ or ‘cultural’ niche and … Continue reading

Pigeons better at multitasking than Humans

Pigeons are capable of switching between two tasks as quickly as humans — and even more quickly in certain situations. These are the findings of biopsychologists who had performed the same behavioral experiments to test birds and humans. The authors … Continue reading
