The brain pulses because it is directly affected by the heartbeat.
The Brain's Rhythmic Motion
The human brain doesn't remain still; it subtly moves with each beat of the heart. This pulsation isn't some mysterious phenomenon; it's a result of the cardiovascular system's impact on the brain.
-
Heart's Role: Each time the heart pumps blood, it creates a pressure wave that travels through the arteries. This wave reaches the brain, causing a tiny, rhythmic jiggle.
-
Brain Movement: This pulsation is so subtle that, for a long time, scientists weren't aware of it. However, modern technology has allowed us to observe and even measure this minute movement. Neuroscientist Ueli Rutishauser, Ph. D., initially thought he had discovered a new effect but it was found that the brain was just pulsing with the heartbeat.
Why Does This Matter?
While the brain's pulsation might seem like a minor detail, it can offer vital insights into brain function.
Implications
-
Neural Activity: Scientists now believe that this rhythmic motion might affect neuronal activity. By studying this motion, we can understand more about how brain cells communicate and function.
-
Diagnostic Tool: Tracking brain pulsations could potentially help diagnose neurological conditions in the future. Analyzing deviations from the standard pulsation pattern might reveal abnormalities.

Conclusion
In essence, the brain pulses because it is a physical structure directly connected to the circulatory system. The heart's pumping action sends a pressure wave to the brain, resulting in a rhythmic, if subtle, pulsation. This pulsation may hold significant clues to how the brain functions.
