Mouse brain


The mouse brain refers to the brain of Mus musculus. Various brain atlases exist.
For reasons of reproducibility, genetically characterized, stable strains like C57BL/6 were chosen to produce high-resolution images and databases. Well known online resources include:

Despite superficial differences, especially in size and weight, the mouse brain and its function can serve as a powerful animal model for study of human brain diseases or mental disorders. This is because the genes responsible for building and operating both mouse and human brain are 90% identical.

Anatomy

The cerebral cortex of a mouse has around 8-14 million neurons while in those humans there are more than 10-15 billion. The olfactory bulb volume takes about 2% of the mouse brain by volume in contrast to about 0.01% of the human brain.
