まとめ
ネズミは他人の傷をいで 痛みを和らげます 脳の前帯状皮質 (ACC) は 痛みに対する社会的反応において 重要な役割を果たします
科学分野:
- 神経科学
- 動物 の 行動
- 社会的認知
背景:
- 社会的支援行動は 種を超えて観察されています
- 他人の痛みに反応する 支援行動の背後にある 神経機構は ほとんど知られていません
研究 の 目的:
- 痛みを経験するマウスの 助ける行動の 神経的基盤を調査するためです
- 傷に対する社会的反応に関与する脳の領域を特定する.
主な方法:
- 傷ついた同種に対するマウスのアロリック (社会的) 行動が観察された.
- 前帯状皮質 (ACC) の神経活動を記録するために微視内視画像を用いた.
- ACCの因果的な役割を評価するために機能的操作を行いました.
主要な成果:
- ネズミは傷付いた部位に 標的を絞り込み,受容体の痛みを和らげる.
- ACCの神経活動は,一般的なストレスとは異なる,他者の特定の痛みの状態をコードします.
- ACCの活動は,標的型アロリック行動を因果的に制御する.
- 疼痛関連の助けのためのACCの集団コードは,アログルーミングのそれとは異なります.
結論:
- 前帯状皮質は 痛みに反応する 支援行動の調整に不可欠です
- ACCにおける神経表現は 痛みに関連した行動と ストレスに関連した社会的行動を区別する.
- この研究は共感と助けの 神経的基盤の洞察を 提供しています

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.

Bystander Effect

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

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.

Pain

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...
