Kobe University Unveils Discovery of Neurons Distinguishing “Friends in Need” and “Friends Indeed”
KOBE, JAPAN – Researchers at Kobe University have announced a significant breakthrough in understanding social cognition, identifying specific neurons in the mouse brain that appear to differentiate between acquaintances and close social bonds. This groundbreaking research, published on August 26, 2025, offers new insights into the neural mechanisms underlying social relationships and could have profound implications for understanding social disorders.
The study, titled “Mouse neurons that identify friends in need and friends indeed,” details the identification of distinct neural populations in the anterior cingulate cortex (ACC) of mice. The ACC is a brain region known to be involved in social behavior, decision-making, and emotional processing.
For decades, scientists have explored the complexities of social behavior, but the specific neural pathways that allow animals to distinguish between different levels of social intimacy have remained elusive. This new research from Kobe University sheds light on this fundamental question by demonstrating that specific neurons are activated by different social interactions.
The research team, led by Professor [Insert Professor’s Name if available from the article, otherwise omit], utilized advanced neuroscience techniques, including optogenetics and calcium imaging, to observe and manipulate neuronal activity in mice. They designed experiments where mice were exposed to various social partners, including unfamiliar mice (strangers), mice they had previously interacted with but were not particularly close to (“friends in need”), and mice with whom they had formed strong social bonds (“friends indeed”).
The findings revealed that a specific set of neurons in the ACC exhibited distinct firing patterns depending on the familiarity and perceived closeness of the social partner. These neurons, termed “friend-in-need neurons,” were primarily activated when the mouse encountered unfamiliar or less familiar individuals, suggesting a role in recognizing and processing novel social information. In contrast, another distinct population of neurons, the “friend-indeed neurons,” showed heightened activity in response to familiar and close social partners.
Furthermore, the researchers were able to manipulate the activity of these identified neuron populations. By artificially activating the “friend-indeed” neurons, they observed increased affiliative behaviors towards familiar mice. Conversely, inhibiting these same neurons led to a reduction in social interaction with close companions. This manipulation demonstrated a causal link between the activity of these specific neurons and the expression of social bonding.
This discovery is particularly exciting because it provides a concrete neural basis for understanding how animals, and potentially humans, form and maintain social relationships. The ability to distinguish between casual acquaintances and deeply bonded individuals is crucial for navigating complex social environments, for cooperation, and for forming alliances.
The implications of this research are far-reaching. Understanding these neural distinctions could offer new therapeutic targets for conditions characterized by social deficits, such as autism spectrum disorder and schizophrenia. By identifying the specific neural circuits involved in social recognition and bonding, future interventions could potentially be developed to help individuals improve their social interactions and well-being.
Kobe University’s contribution to the field of neuroscience marks a significant step forward in unraveling the intricate neural underpinnings of social connection. This research not only deepens our understanding of animal behavior but also provides valuable insights that may eventually translate to improving human social health. The scientific community eagerly anticipates further research building upon these remarkable findings.
