The new study unveils the existence of multiple correlations between brain complexity and locomotion pattern in vertebrates, indicating that locomotion mode is a strong predictor of cerebellar size, shape, neuron organization, and gene expression levels. This demonstrates the existence of specific type of brain shared by animals with lifestyle or behavior similarities.
"The cerebellum is a major component of the brain that contributes to coordination, precision, and accurate timing of movement, and the diversity of this brain region is remarkable across vertebrates," describes Principal Investigator Nicolas Di-Poï, Associate Professor at the Institute of Biotechnology, University of Helsinki.
Research - Studies - Factors - Habitat - Locomotion
Research studies have previously shown that behavioral and ecological factors such as diet, habitat, locomotion, cognitive abilities and lifespan play an important role in driving animal brain evolution. However, comparative studies have so far largely focused on brain size measurements, and the ecological relevance of potential multi-level variations in brain morphology and architecture had remained unclear until now.
Researchers from the University of Helsinki hypothesized that in addition to expected...
