D. Kenyan Teen’s Chinese Bridge Win Fuels National Learning Passion.
C
It is widely recognized that the human brain, particularly brain cells, functions as the central storage site responsible for storing memories. Nevertheless, a team of scientists has discovered that cells in other parts of the body can also exhibit memory capabilities. This discovery provides a new perspective for further investigation of memory mechanisms.
Nikolay V. Kukushkin from New York University, the lead author of the study in Nature Communications, explains, “Learning and memory are usually linked only to brains and brain cells, but our study reveals that other body cells can learn and form memories too.”
The research aimed to explore whether non-brain cells assist memory by using the “massed-spaced effect”—a learning principle where information is remembered more effectively through spaced-interval study periods compared to trying to learn everything in one long, exhausting session, better known as cramming(考前突击) for a test.
Scientists studied two types of non-brain human cells in a lab. They exposed these cells to different chemical signal patterns, similar to how brain cells receive neurotransmitter patterns(神经递质模式) during learning. In response, the non-brain cells activated a “memory gene”—identical to that of the brain cells when detecting patterns and restructuring connections for memories.
To monitor the process, the scientists engineered the non-brain cells to produce a glowing protein, which showed when the memory gene was on or off. The results showed that these cells could distinguish repeated chemical pulses (imitating brain neurotransmitter bursts) from simply continuous ones. When the pulses were spaced out, the “memory gene” was turned on more strongly and for longer.
