Resumen
Los ratones muestran un comportamiento de ayuda lamiendo las heridas de los demás, ayudando a aliviar el dolor. La corteza cingulada anterior (ACC) en el cerebro juega un papel clave en esta respuesta prosocial al dolor.
Área de la Ciencia:
- La neurociencia
- El comportamiento de los animales
- Conocimiento social
Sus antecedentes:
- Los comportamientos prosociales de ayuda se observan en todas las especies.
- Los mecanismos neuronales que subyacen al comportamiento de ayuda en respuesta al dolor de los demás son en gran medida desconocidos.
Objetivo del estudio:
- Investigar las bases neuronales del comportamiento de ayuda en ratones que experimentan dolor.
- Para identificar las regiones del cerebro involucradas en las respuestas prosociales a la lesión.
Principales métodos:
- Comportamiento de lamer social observado en ratones hacia sus congéneres lesionados.
- Utilizó imágenes microendoscópicas para registrar la actividad neuronal en la corteza cingulada anterior (ACC).
- Se realizaron manipulaciones funcionales del ACC para evaluar su papel causal.
Principales resultados:
- Los ratones muestran alolicación dirigida hacia los sitios de la lesión, lo que alivia el dolor del receptor.
- La actividad neuronal del ACC codifica el estado específico de dolor en otros, distinto del estrés general.
- La actividad del ACC controla de manera causal el comportamiento de aliciamiento dirigido.
- La codificación de la población en el ACC para la ayuda relacionada con el dolor difiere de la del alogrooming.
Conclusiones:
- La corteza cingulada anterior es crucial para regular el comportamiento de ayuda dirigido en respuesta al dolor.
- Las representaciones neuronales en el ACC diferencian entre los comportamientos prosociales relacionados con el dolor y los relacionados con el estrés.
- Este estudio proporciona información sobre los fundamentos neuronales de la empatía y la ayuda.

Voluntary behavior with the intent to help other people is called prosocial behavior. Why do people help other people? Is personal benefit such as feeling good about oneself the only reason people help one another?

02:34Empathy

Some researchers suggest that altruism operates on empathy. Empathy is the capacity to understand another person’s perspective, to feel what he or she feels. An empathetic person makes an emotional connection with others and feels compelled to help (Batson, 1991). Empathy can be expressed in several ways, including cognitive, affective, and motor.

The discussion of bullying highlights the problem of witnesses not intervening to help a victim. This is a common occurrence, as the following well-publicized event demonstrates. In 1964, in Queens, New York, a 19-year-old woman named Kitty Genovese was attacked by a person with a knife near the back entrance to her apartment building and again in the hallway inside her apartment building. When the attack occurred, she screamed for help numerous times and eventually died from her stab wounds.

Nociception—the ability to feel pain—is essential for an organism’s survival and overall well-being. Noxious stimuli such as piercing pain from a sharp object, heat from an open flame, or contact with corrosive chemicals are first detected by sensory receptors, called nociceptors, located on nerve endings. Nociceptors express ion channels that convert noxious stimuli into electrical signals. When these signals reach the brain via sensory neurons, they are perceived as pain.

01:20Pain

Pain serves as a critical warning signal that alerts the body to potential or actual harm. When mechanical pressure on the skin is intense, such as from a sharp pinch, the sensation transitions from touch to pain. Similarly, extreme temperatures, like a hot pot handle, convert the sensation of heat into pain. Pain can also result from overstimulation of other senses, such as blinding light, loud noise, or the intense heat from habañero peppers. This ability to sense pain is essential for...

The history of therapeutic communication can be traced back to Florence Nightingale, who emphasized the importance of developing trusting relationships with patients. She taught that the presence of nurses with patients results in therapeutic healing.
