Mechanisms and rules of social learning in crickets
Learning & Behavior - Trang 1-2 - 2023
Tóm tắt
A new study on insect social learning shows that crickets learn to prefer a rewarded odorant by observing the choice of a conspecific and without experiencing the reward themselves. The mere perception of the conspecific activates octopaminergic reward neurons in the brain of the observer, thus facilitating odorant learning.
