Woodpeckers: There Are Advantages to Having a Small Brain

Woodpeckers absorb 1200 to 1400 g shock driving their beaks into wood — but a shock absorbing skull doesn’t explain the absence of damage

How do woodpeckers absorb a remarkable amount of shock to the head — 1200 to 1400 g — for each hit on a tree? A football player might absorb 120 g — without damaging their brains? The answers could help minimize brain damage in humans and suggested explanations include a surplus of tau proteins (2017), an unusual bone in the tongue, and head movements that minimize brain damage. A new research team challenges such explanations saying that their data show that woodpecker heads” act more like stiff hammers” and that “any shock absorbance would hinder the woodpeckers’ pecking abilities.” But then what about the bird’s brain? While the deceleration shock with each peck exceeds the known threshold for a concussion…

Bingecast: Yuri Danilov on the Complexity of our Brains

Recent discoveries about the brain have uncovered more of its complexity and changed what we thought we knew about it. Will more discoveries in the future change our views again? Robert J. Marks discusses neuroplasticity, restoring brain function through brain stimulation, and other fascinating discoveries about the human brain with Yuri Danilov. Show Notes 0:01:13 | Introducing Yuri Danilov, Senior…

Do Big Brains Matter to Human Intelligence?

We don’t know. Brain research readily dissolves into confusion at that point

We also know very little about the human brain. Take this controversy about why the large human brain evolved...
