Virtual reality is changing the way we study the brain.¹ It offers a chance to see how the brain works in a more natural setting, improving on the old methods.¹ It gives scientists the ability to control what someone sees, interacts with, and records. Because of this, we’re learning more about how the brain handles things like finding our way around, moving and thinking, and other complex tasks.¹ As VR gets better and we pair it with other advanced tools, such as mind-controlled devices and enhanced reality, the options for studying the brain will only grow. This could lead us to a better understanding of how the brain handles everyday actions.

Introduction to Virtual Reality in Neuroscience

VR in neurophysiology allows us to study behavior while recording, using devices not easily portable by the subject or needing stability that’s hard to get when moving freely.¹ Its potential isn’t just about restricting movement in experiments. VR stands out from traditional methods by creating more natural actions and understanding the brain’s functions better, although it offers similar control.

The Importance of Naturalistic Behavior Study

Experiments in the lab usually repeat the same set of prompts, mainly for one sense, in simple and fake settings. These experiments don’t often connect to the animal’s natural reactions. This approach helps in modeling behavior and finding neural associations. However, the results may not apply to real-life behavior and might miss the true brain mechanisms.

Limitations of Traditional Laboratory Experiments

Laboratory tests often use repeated prompts, focusing on one sense, in basic and artificial settings. They usually don’t capture the animal’s real reactions. Even though these tests are crucial for studying behavior and brain functions, their real-life application is limited. They might not clearly show how the brain naturally behaves.

VR as a Solution for Naturalistic Neuroscience

Virtual reality can help solve the issue of lab experiments lacking real-world accuracy. It creates a virtual world where the user’s movements shape their experiences, closing the gap between stimulus, perception, and response. This enables more life-like experiments and a better understanding of how the brain works in natural situations.¹

What is Virtual Reality?

LaValle (2020) explains VR as using tech to guide actions without the user fully knowing it. While exploring VR in research, people might sense things that seem real but are actually created by scientists.²

Definition and Key Aspects of VR

In virtual reality, the digital world is constantly refreshed to match what the user is doing. This updating must be fast to fit the user’s ability to sense and move.³
