Scientists discover new mechanism controlling brain size

Under the leadership of Professor Lars Allan Larsen and Professor Søren Tvorup Christensen at University of Copenhagen (UCPH), Denmark, an international research team has taken an important step forward in understanding ...

The surprising organisation of avian brains

Birds and mammals have the largest brains in relation to their body. Apart from that, however, they have little in common, according to scientific opinion since the 19th century: mammalian brains have a neocortex, i.e. a ...

The face of a mouse reveals its emotions: study

Researchers at the Max Planck Institute of Neurobiology are the first to describe emotional facial expressions for mice. Similar to humans, mouse facial expressions change when it tastes something sweet or bitter, or when ...

New study reveals early evolution of cortex

Research on the lamprey brain has enabled researchers at Karolinska Institutet in Sweden to push the birth of the cortex back in time by some 300 million years to over 500 million years ago, providing new insights into brain ...

Rats avoid hurting other rats

Most humans feel bad about hurting others. This so-called "harm aversion" is key to normal moral development and is reduced in violent antisocial individuals. Unfortunately, little is known about what makes people harm-averse, ...

New function for potential tumor suppressor in brain development

The gene Cdkn1c could have been considered an open-and-shut case: Mice in which the gene is removed are larger and have bigger brains, so Cdkn1c should function to inhibit growth. This rationale has led to Cdkn1c being studied ...

When social interaction helps you choose your food

How do we choose our food? By studying the neurobiological mechanisms involved in food choices of rodents, neuroscientists at the University of Geneva (UNIGE), Switzerland, have identified the important and lasting influence ...
