In an environment with many stimuli, mice experience it differently. In one mouse (right) it leads to many new neurons (black dots), while in another mouse (left), significantly fewer new neurons develop.

Experience leads to the growth of new brain cells
A new study examines how individuality develops
How do organisms evolve into individuals that are distinguished from others by their own personal brain structure and behaviour? Scientists in Dresden, Berlin, Münster, and Saarbrücken have now taken a decisive step towards clarifying this question. Using mice as an animal model, they were able to show that individual experiences influence the development of new neurons, leading to measurable changes in the brain. The results of this study are published in Science on May 10th. The DFG-Center for Regenerative Therapies Dresden – Cluster of Excellence at the TU Dresden (CRTD), the Dresden site of the German Center for Neurodegenerative Diseases (DZNE), and the Max Planck Institute for Human Development in Berlin played a pivotal role in the study.
