Summary: Researchers found that, among pairs of people who had very different socioeconomic backgrounds – calculated according to education level and family income – there was a higher level of activity in an area of the frontal lobe called the left dorsolateral prefrontal cortex. The area is associated with speech production and rule-based language as well as cognitive and attentional contr
Summary: A team of researchers has identified networks of genes that regulate the process responsible for determining whether neurons will regenerate in certain animals, such as zebrafish
Summary: A research team has systematically investigated the cognitive abilities of lemurs, which have relatively small brains compared to other primates. Conducting systematic tests with identical methods revealed that cognitive abilities of lemurs hardly differ from those of monkeys and great apes. Instead, this study revealed that the relationship between brain size and cognitive abilities cannot be generalized and it provides new insights into the evolution of primates.

Summary: Bayesian brain theories suggest that perception, action and cognition arise as animals minimise the mismatch between their expectations and reality. This principle could unify cognitive science with the broader natural sciences, but leave key elements of cognition and behaviour unexplained.
Summary: Study links brain structure to color perceptual function. Microscopy revealed ‘hue maps,’ or color palettes, in the brain that are spectrally organized arrangements of hue responses.
