In a study published in Neuron, a research team led by Prof. Wang Liping from the Shenzhen Institutes of Advanced Technology (SIAT) of the Chinese Academy of Sciences revealed the neural circuit underlying individual differences in visual escape habituation.
Emotional responses, such as fear behaviors, are evolutionarily conserved mechanisms that enable organisms to detect and avoid danger, ensuring survival. Since Darwin’s “On the Origin of Species” (1859) proposed that individual differences drive natural selection, understanding behavioral adaptation has become essential for unraveling biodiversity and survival strategies.
Repeated exposure to predators can elicit divergent coping strategies—habituation or sensitization—that are dependent on sensory inputs, internal physiological states, and prior experiences. However, the neural circuits underlying individual variability in the regulation of internal states and habituation to repeated threats remain poorly understood.
