Abstract in brief

The study uses X-ray tomography of Early Jurassic mammal fossils to explore how the mammalian brain evolved, highlighting two major evolutionary pulses that increased brain size to mammalian levels
The first pulse involved enhancements in olfactory sensitivity, tactile sense, and neuromuscular coordination, leading to initial brain expansion
A second pulse further amplified olfactory capabilities, with the development of ossified ethmoid turbinals supporting a larger odorant receptor repertoire in crown mammals
