Perineuronal nets (PNNs) stabilize the grid cell network by maintaining inhibitory neuron activity, which is crucial for forming and retaining stable spatial representations. This user-centred design research insight is drawn from a 2021 study published in Nature Communications. Using Experimental animal study (rodents), researchers explored how this design variable affects real-world outcomes. The key design takeaway: To enhance the stability and retention of spatial information in user's mental models, design for consistent, predictable structures and minimize elements that could introduce 'noise' or 'corruption' to established representations.

Application
Design takeaway
To enhance the stability and retention of spatial information in user's mental models, design for consistent, predictable structures and minimize elements that could introduce 'noise' or 'corruption' to established representations.
How to apply
When designing complex information architectures or navigation systems, ensure that core spatial relationships and landmarks remain consistent across different contexts or updates to prevent 'corruption' of the user's mental map. For example, consistent iconography and layout for key functions in a complex software suite.
Project actions
- 01When designing a navigation system or a virtual environment, think about how to make the 'spatial map' in the user's mind as stable as possible.
- 02Consider how new information or changes in the environment might 'corrupt' a user's existing mental model, and design ways to mitigate this.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Provides a clear biological mechanism for spatial memory stability.
- +Uses multiple measures (neural activity, behavioral response, downstream effects) to support its claims.
Limitations
The study is on animal models, so direct application to human design is an analogy. We can't 'remove PNNs' in a design, but we can learn from the *function* they provide.
Reliability & validity
The study's use of established neuroscientific techniques and multiple outcome measures (neural activity, behavioral observation) contributes to its internal validity. Reliability is supported by the consistent effects observed across different measures. External validity to human cognition requires further research.
Think critically
How can the concept of 'stabilizing the grid cell network' be translated into concrete design principles for a digital product, considering that we cannot directly manipulate brain structures?
Design Principles
"Cognitive Stability Principle: Designs should promote the stable formation and retention of mental models by minimizing disruptive elements and reinforcing consistent patterns."
Our ability to navigate and remember places relies on stable neural maps in the brain. PNNs act like structural supports for these maps, ensuring that our mental representation of an environment remains consistent, even when we encounter new information. Without this stability, our spatial memories could become easily corrupted or lost.
What This Means for Your Design
This paper shows that special structures in the brain, called perineuronal nets (PNNs), are super important for keeping our brain's 'GPS system' (grid cells) stable. Without these PNNs, our brain struggles to learn new places and even forgets old ones, because the brain's internal map gets messed up.
How to use in your project
- 1.When designing an Information Architecture, ensure that the 'spatial' relationships between categories and content are consistent and predictable, mirroring the stability PNNs provide in the brain. Avoid frequent, drastic changes to navigation structures that could 'corrupt' a user's learned mental model.
