Beyond nature, nurture, and chance: Individual agency shapes divergent learning biographies and brain connectome.

Individual choices shape life course trajectories of brain structure and function beyond genes and environment. We hypothesized that individual task engagement in response to a learning program results in individualized learning biographies and connectomics. Genetically identical female mice living in one large shared enclosure freely engaged in self-paced, automatically administered and monitored learning tasks.

Inexpensive, scalable camera system for tracking rats in large spaces.

Most studies of neural correlates of spatial navigation are restricted to small arenas (≤1 m) because of the limits imposed by the recording cables. New wireless recording systems have a larger recording range. However, these neuronal recording systems lack the ability to track animals in large area, constraining the size of the arena.
