What if understanding the brain required thinking like a mechanical engineer?
In this episode of Neurocareers: Doing the Impossible, we explore an emerging field that is reshaping neuroscienceāneuromechanics, where forces, stiffness, and material properties become key to understanding the brain and spinal cord.
š§ From Engineering to Neuroscience
Professor Silvia Budday and doctoral researcher Oskar Neumann share their unconventional journeys into neuroscienceāfrom mechanical and civil engineering into one of the most interdisciplinary frontiers of brain research.
Oskarās path began in civil engineering, where he studied structures, materials, and mechanics before transitioning into neuromechanics and modeling spinal cord tissue. Silviaās journey led her to apply continuum mechanics to the brainārevealing insights that traditional neuroscience alone could not explain.
Their stories highlight a powerful
idea:
š Sometimes the biggest breakthroughs come from outside the
field.
š§ Understanding the Brain as a Mechanical System
At the core of neuromechanics is a
fundamental question:
How do mechanical forces shape the nervous
system?
Their work shows that the brain is not just biologicalāit is also:
Ultra-soft and highly dynamic
Viscoelastic, meaning it responds differently over time and under
different conditions
Sensitive to forces, pressure, and deformation
Key insights include:
Brain folding during development can arise
from mechanical compression
Neural cells respond to stiffness gradients, guiding growth and
regeneration
Gray and white matter behave differently depending on how they are
tested
These discoveries challenge long-held assumptions and open new ways of understanding brain function and disease.
š§ Challenges: Studying the Softest Tissue in the Body
Working with brain and spinal cord tissue presents unique challenges:
Extreme softness makes experiments
difficult and highly variable
Results differ depending on measurement method, scale, and
conditions
Translating findings from ex vivo to in vivo remains complex
Bridging language and knowledge across disciplines, from
engineering to biology
As Oskar describes, even measuring something as āsimpleā as stiffness becomes a complex scientific problem.
š¬ Bridging Scales: From Cells to Systems
One of the most exciting aspects of neuromechanics is its ability to connect multiple levels of the nervous system:
Cellular level: how neurons sense and
respond to mechanical cues
Tissue level: how properties like stiffness influence structure
System level: how the brain deforms during surgery or injury
By combining experiments with computational models, their work aims to build digital twins of the braināsimulations that could transform research and clinical practice.
š Applications & Future Directions
Neuromechanics is opening new possibilities across neuroscience and medicine:
Spinal cord injury and regeneration,
including stiffness-guided repair strategies
Neurosurgery, by accounting for brain deformation during
procedures
Brain development and disorders, including epilepsy-related
malformations
Biomaterials design, such as hydrogels for tissue repair
Looking ahead, the field is moving toward:
Integration of AI with physics-based
models
Development of patient-specific brain simulations
Better in vivo measurement techniques
š” Career Insights for Aspiring Neurotech Innovators
Silvia and Oskar offer powerful advice for those entering the field:
Your original discipline is your
strengthānot a limitation
You donāt need to know everything about neuroscience to start
Learn by collaborating across fields
Be ready to build a āshared languageā with other disciplines
Curiosity and persistence matter more than a perfect background
š Interdisciplinary science is not about switching fieldsāitās about connecting them.
š± Closing Reflection
This episode reveals a profound shift in how we think about the brain.
What once seemed unlikelyāusing mechanical engineering to understand neural functionāis now unlocking entirely new directions in neuroscience.
As this field grows, one thing becomes
clear:
The future of neuroscience belongs to those who can think
across boundaries.

Oskar Neumann
Oskar Neumann is a doctoral researcher in neuromechanics at Friedrich-Alexander-UniversitƤt ErlangenāNürnberg (FAU). With a background spanning civil engineering, mechanics, and computational modeling, his work focuses on the mechanical characterization and simulation of spinal cord tissue.
Oskarās career path highlights the interdisciplinary nature of neuromechanics itself: he began by studying structures and materials in civil engineering before applying those same principles to one of the softest and most complex materials in natureāthe nervous system.
His research explores how mechanical propertiesāsuch as stiffness and loading conditionsāaffect spinal cord injury and regeneration, contributing to more realistic models of nervous tissue and future therapeutic strategies.
