Collection: Heart Brain Cells

Modern Scientific Discovery:

Recent scientific research has revealed that the heart is more than just a pump. It contains about 40,000 neurons, allowing it to communicate with the brain and even influence thoughts and emotions. Scientists now refer to this as the "heart’s little brain" (the intrinsic cardiac nervous system).

🔬 Key Scientific Facts:

• The heart sends more signals to the brain than the brain sends to the heart.
• Studies show the heart can process information, make decisions, and regulate emotions.
• The heart releases hormones like oxytocin, which play a role in love, bonding, and emotional stability.
• The heart and brain work together, and the heart influences our cognitive functions and emotional well-being.

This discovery was made in modern neuroscience, but the Qur’ān mentioned a reasoning heart over 1400 years ago.

Qur’ānic Revelation:

أَفَلَمْ يَسِيرُوا۟ فِى ٱلْأَرْضِ فَتَكُونَ لَهُمْ قُلُوبٌۭ يَعْقِلُونَ بِهَآ أَوْ ءَاذَانٌۭ يَسْمَعُونَ بِهَا ۖ فَإِنَّهَا لَا تَعْمَى ٱلْأَبْصَـٰرُ وَلَـٰكِن تَعْمَى ٱلْقُلُوبُ ٱلَّتِى فِى ٱلصُّدُورِ ٤٦

English Translation:

"Have they not traveled throughout the land so their hearts may reason, and their ears may listen? Indeed, it is not the eyes that are blind, but it is the hearts in the chests that grow blind."
📖 (Qur’ān 22:46)

Scientific Explanation:

The Qur’ān states that the heart "reasons" (يعقلون بها), which aligns with modern research showing that the heart contains neurons and a complex network that affects human cognition and emotions.

Why is this important?

• At the time of revelation, no one knew the heart had neurons or played a role in reasoning.
• Ancient medical theories saw the heart only as a pump, but modern science confirms it can process information and influence decision-making.
• The Qur’ān does not say that only the brain reasons, but specifically mentions the heart’s role in understanding, which science has now verified.

Conclusion:

The discovery that the heart has neurons and influences emotions and cognition aligns perfectly with the Qur’ān’s mention of a reasoning heart. This knowledge, revealed over 1400 years ago, was far beyond human understanding at that time. The verse serves as a scientific and spiritual reminder of the deep wisdom found in the Qur’ān.
