Application

Design takeaway

How to apply

When designing solutions for complex biological or neurological issues, consider using animal models as a preliminary stage of testing and validation, especially if human trials are costly or ethically challenging.

Project actions

01Consider using a simplified animal model (e.g., a different species of mammal) to represent a complex system in your design project.
02Explore how imaging techniques, even conceptually, could be used to gather data about your design's performance or user interaction.
03Investigate how existing research in animal models informs the design of products or systems for humans.

Method & Evidence

AimTo review the current knowledge on rs-fMRI and PET biomarkers in the study of normal and abnormal neurodevelopment, evaluating the cross-species translational value of these imaging biomarkers.

MethodReview of existing research and literature.

ProcedureThe authors reviewed studies utilizing resting-state functional magnetic resonance imaging (rs-fMRI) and positron emission tomography (PET) to investigate neurodevelopmental disorders in both humans and rodent models. They assessed the utility of these imaging biomarkers and their translatability across species.

ContextNeuroscience, specifically the study of neurodevelopmental disorders (NDDs) like intellectual disability, autism spectrum disorder (ASD), and attention deficit hyperactivity disorder (ADHD).

Variables

IVType of neurodevelopmental disorder, species (human/rodent), age/developmental stage.

DVBrain network activity patterns, presence/severity of NDD symptoms, treatment response.

CVImaging technique used (rs-fMRI, PET), specific brain regions analyzed, experimental protocols.

Strengths & Limitations

Strengths

+Comprehensive review of a complex topic.
+Highlights the potential of cross-species modelling for NDD research.

Limitations

Animal models are not perfect replicas of human conditions. Findings from rodent studies may not always translate directly to humans due to biological differences.

Reliability & validity

The reliability of imaging techniques like rs-fMRI and PET is generally high, but validity in cross-species translation remains an area for further research. The review synthesizes findings from multiple studies, increasing the overall validity of its conclusions.

Think critically

To what extent can findings from animal models truly predict human responses, and what are the ethical considerations when designing interventions based on such models?

Design Principles

"Utilize validated animal models and advanced imaging techniques to develop and test interventions, ensuring cross-species translational validity."

This insight is relevant to design as it highlights the use of sophisticated modelling techniques (animal models and imaging) to understand complex biological systems. It demonstrates how researchers use these models to predict outcomes and test interventions before human trials, a crucial aspect of responsible design and development.

What This Means for Your Design

Using animal models that are similar to humans can help scientists understand brain development problems and test new treatments before trying them on people.

How to use in your project

1.In your project, you could use an analogy of a simplified model (e.g., a physical prototype representing a larger structure) to explain how you are testing a concept before full implementation.
2.If your project involves user testing, you could discuss how initial testing on a small group (like an animal model) informs later, larger-scale testing on your target user group.
