Abstract Woodpeckers can withstand a fierce impact during pecking without any brain injury. Although directly involved in the whole pecking, the role of the jaw apparatus played in the impact-resistant process of woodpeckers is still not fully clear. We employed finite element analysis, impact tests in vivo, and post-traumatic brain anatomical observation to evaluate the protective function of the jaw apparatus. Forehead impact model and beaks impact without quadrate joints model were selected… Expand


Structural analysis of the tongue and hyoid apparatus in a woodpecker.
The combined microstructural and mechanical property analysis indicate possible energy absorption routes for the hyoid apparatus and are applicable to the design of engineered structures. Expand
Mechanical Evaluation of the Skeletal Structure and Tissue of the Woodpecker and Its Shock Absorbing System
It is considered that woodpecker has the advanced impact-proof system relating with not only the head part but also with the whole body, as the unique states of hyoid bone, skull, tissue and brain. Expand
Numerical study of the impact response of woodpecker's head
Woodpecker can beat trees 20-25 times per second and lasts for several seconds, with a 1200 g deceleration, but it appears that they never get brain concussion. How does the stress wave propagateExpand
A Natural Stress Deflector on the Head? Mechanical and Functional Evaluation of the Woodpecker Skull Bones
The brain is one of the most important and complicated organs, but it is delicate and therefore needs to be protected from external forces. This makes the pecking behavior of the Woodpecker soExpand
Micro-mechanical properties of different sites on woodpecker’s skull
The mechanical properties, site-dependent hardness distribution and special material composition of GSW’s skull bone are newly found and may lead to a new design of bulk material mimicking these characteristics. Expand
The geometric effects of a woodpecker's hyoid apparatus for stress wave mitigation.
The analysis of the woodpecker's hyoid apparatus provides a novel perspective on impact mitigation mediated by a spiral-shaped structure and viscoelastic biocomposite. Expand
Why Do Woodpeckers Resist Head Impact Injury: A Biomechanical Investigation
The result showed that macro/micro morphology of cranial bone and beak can be recognized as a major contributor to non-impact-injuries and may inspire new approaches to prevention and treatment of human head injury. Expand
Effect of microstructure of spongy bone in different parts of woodpecker's skull on resistance to impact injury
Natural biological materials such as bone, teeth and nacre are nano-composites of protein and mineral frequently exhibit highly superior strength for self-assembly and nanofabrication. Mineral massExpand
Reconsidering the woodpecker model of traumatic brain injury
The 2017 McDonald criteria for patients with a progressive course from onset were not changed from the 2010 McDonald criteria, aside from including cortical brain MRI lesions in addition to juxtacortical lesions to make the diagnosis and that no distinction between symptomatic and asymptomatic MRI lesions is required.
