The article explores recent findings on how sleep, particularly the REM phase, affects learning capabilities and motivation in horses. Researchers have conducted studies revealing that a lack of REM sleep can lead to cognitive decline in equine learning outcomes. The implications of this research not only shed light on horse training but also reflect on the broader understanding of learning processes among mammals, including humans.

Mira Hämäläinen, a veterinarian specializing in equine diseases, designed a reverse learning test to evaluate cognitive abilities in horses. This test attempts to assess how well horses can adapt their behavior when they are required to learn new tasks in familiar environments. The study involved horses from a local riding school, showcasing their ability to learn tasks when conditions are altered, thereby contributing valuable insights into equine intelligence and adaptability.

The findings from this research could have significant implications for horse training practices, suggesting that optimizing sleep patterns may enhance a horse's ability to learn and perform. Additionally, the similarities drawn between equine and human learning mechanisms can lead to improved understanding of cognitive development in various species, emphasizing the need for proper rest in training contexts.
