Research by SBS member Prof. Ke Ya confirms the existence of discrete number sense in rats
Research co-led by neuroscientists Prof. Ke Ya at the School of Biomedical Sciences (SBS) of The Chinese University of Hong Kong (CUHK) and Prof. Yung Wing-ho at City University of Hong Kong (CityUHK) has made a groundbreaking discovery regarding number sense in animals by confirming the existence of discrete number sense in rats, offering a crucial animal model for investigating the neural basis of numerical ability and disability in humans.
The research team has developed an innovative approach that employs a novel numerical learning task, brain manipulation techniques and artificial intelligence modelling, and that resolves an ongoing argument about whether rats have a sense of numbers. The study sheds light on the mechanisms underlying numerical ability. The findings have been published in the renowned multidisciplinary scientific journal Science Advances.
“The study not only solves a long-standing mystery about how brains handle numbers, but also offers new insights into studying the specific neural circuits involved in number processing in animals and how genes are associated with mathematical ability,” Prof. Ke Ya said. “Furthermore, the findings from neural network modelling could have practical applications in the field of artificial intelligence. In the future, our increased understanding of the brain mechanisms underlying the processing of numbers may contribute to the development of interventions for individuals with numerical difficulties.”

香港中文大學(中大)生物醫學學院柯亞教授及香港城市大學(城大)容永豪教授兩位神經科學專家共同領導一項研究,透過大鼠實驗突破性地發現動物擁有理解數字的能力(即「數感」),為研究人類理解數字能力和相關障礙的神經科學基礎,提供了關鍵的動物模型。
研究團隊通過採用嶄新的數字學習任務、腦活動干預技術和人工智能模型,開發了一種創新方法,解決關於大鼠是否具有數感的爭論。研究結果揭示了數感背後的機制,詳細內容已於著名跨學科期刊《科學進展》發表。
柯亞教授說:「這項研究不僅解開多年來關於大腦如何處理數字的謎團,更為研究動物處理數字所涉及的具體神經路徑,以及與數學能力相關的基因,提供有力基礎。此外,神經網絡模型的研究結果在人工智能領域具有實際應用價值。日後,當我們對大腦處理數字的機制有更深入理解後,或可開發針對數感缺陷人士的干預措施。」
