Neuroscientists have never fully understood how new adult brain cells are able to traverse the relatively long distances they need to cover in order to reach their final locations within the brain. LiveScience.com is reporting today that a recent study of mouse brains co-authored by researchers at the University of California, San Francisco sheds some light on the important role that cilia play in brain cell migration.

A mouse

It was announced yesterday that in an effort to create better models for studying neurological disorders, a team of scientists from the Salk Institute led by Dr. Fred Gage have successfully bio-engineered mice to be born with a small percentage of human brain cells. The process involves injecting 2-week-old mouse embryos with roughly 100,000 human embryonic stem cells. The mice created could be a valuable asset to scientists as they struggle to understand and combat neurological disorders like epilepsy and Parkinson’s disease.

AMouse - A robot mouse with whiskers

source: M. Fend

As part of the Artificial Mouse (AMOUSE) Project, researchers from the Artificial Intelligence Laboratory at the University of Zurich have developed a robotic mouse, the AMouse, that navigates by means of an omnidirectional camera, several light sensors, and two active artificial whisker arrays. In nature, vibrissae, better known as whiskers, are important sensors for short-range navigation and environmental exploration. The goal of the research is to learn more about the biology and neurology of rodent behavior and to study the way that the input from long and medium range sensors like the camera and light detectors function with and compliment the short range, somatosensory input provided by the whiskers.
