A unique population of Colombian former guerrillas, who were illiterate until adulthood, are investigated using brain imaging techniques to uncover the gross changes that take place in the brain as the result of learning to read and write.
A chemical in the cuticle of the fruit fly, Drosophila melanogaster, is shown to both identify females of the species as females and to distinguish the flies from those of related species by acting as a suppressor of sexual activity.
Neurons known as place cells encode spatial information that is needed to guide an animal's movement. Nearly 40 years after these cells were discovered, neuroscience gets a look at their internal dynamics.
When a stem cell divides, one sister cell differentiates and the other retains its stem-cell identity. Differences in the age of an organelle -- the centriole -- inherited at cell division may determine these differing fates.
The neurodegenerative disorder Alzheimer's disease is becoming more prevalent in ageing populations worldwide. The identification of effective treatments will require a better understanding of the physiological mechanisms involved, and innovative approaches to drug development and evaluation.
Interviews with David Tank about what virtual reality experiments with mice can reveal about spatial information processing in the brain and Manuel Carreiras on the brains of Colombian guerrillas who are learning to read.
