abstract = {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. We discovered growing and increasingly
stable interindividual differences in learning trajectories.
Adult hippocampal neurogenesis and connectivity as assessed
by a high-density multielectrode array positively correlated
with the variation in exploration and learning efficiency.
During some tasks, divergence transiently collapsed,
highlighting the sustained significance of context for
individualization. Thus, equal environments and equal genes
do not result in equal learning biographies because life
confronts individuals with choices that lead to divergent
paths.},
