A 2026 study published in JMIR Serious Games suggests that long-term experience with first-person shooters (FPS) and multiplayer online battle arena (MOBA) games is associated with different patterns of structural brain connectivity. Rather than arguing that “gaming is good” or “gaming is bad,” the research points to a more nuanced conclusion: different genres appear to place different long-term demands on attention, perception, and sensorimotor processing, and those differences may be reflected in the brain’s structural organization.
Why This Study Matters
Debates around video games often focus on behavior, screen time, or addiction. This study approached the issue from a neuroscience angle by asking whether long-term experience in different competitive genres is linked to genre-specific brain network patterns.
That question matters because FPS and MOBA games train different skills. FPS titles typically demand rapid reactions, precise aiming, auditory cue detection, and fast visual-motor decisions, while MOBA games rely more heavily on strategic planning, visual attention, team coordination, and working memory. If those demands are sustained over years, researchers argued, they may leave detectable signatures in how cortical regions covary structurally.
What the Researchers Examined
The study included 116 male participants with a mean age of 21.2 years. The sample was divided into 39 FPS players, 40 MOBA players, and 37 healthy controls who had no recent gaming experience.
To qualify for the gaming groups, participants had to meet strict criteria: at least 5 years of experience in their main genre, more than 5 hours of play per week in the previous 6 months, and a ranking within the top 15% of players. FPS players also needed to have no meaningful MOBA experience in the past 2 years, while MOBA players needed to have no recent FPS experience.
The control group had no MOBA or FPS experience in the previous 2 years and no gaming activity in the previous 6 months. All participants were right-handed male university students, and those with visual or auditory impairments, neurological or psychological disorders, substance abuse, smoking habits, claustrophobia, or MRI-incompatible implants were excluded.
How the Methodology Worked
Researchers recruited participants through online advertisements at Shanghai University of Sport and screened them using a questionnaire covering eligibility, ranking, and weekly gaming hours. Those who met the criteria then underwent high-resolution structural magnetic resonance imaging on a 3-T Siemens Prisma scanner using a standard MPRAGE protocol with 1×1×1 mm voxel size.
The team focused on cortical thickness, a structural measure that reflects the distance between the pial surface and the white matter boundary. MRI data were preprocessed with CAT12 and SPM12, smoothed with a 15 mm Gaussian kernel, and segmented into 68 cortical regions using the Desikan-Killiany atlas.
From there, the authors built individualized differential structural covariance networks, or IDSCNs. In simple terms, they first created a reference structural covariance network from the control group, then measured how the inclusion of each gamer altered covariance patterns between cortical regions, producing an individualized network for each player.
The statistical pipeline included one-way ANOVA across 4,624 edges, false discovery rate correction, Bonferroni-corrected post hoc tests, network-based statistics with 10,000 permutations, prediction of weekly gaming time using NBS-Predict, and support vector machine classification to test whether the groups could be distinguished from one another based on network features.
The Main Results
The one-way ANOVA identified 30 significant structural covariance edges across the three groups at a false discovery rate–corrected threshold of P<.001. Post hoc analyses showed that FPS players had two dominant network patterns compared with both MOBA players and non-gamers: a temporo-fronto-parietal network centered on auditory regions and a visuo-sensorimotor network.
More specifically, the FPS group showed stronger structural covariance involving the superior temporal and transverse temporal gyri, regions associated with auditory processing, together with frontal, parietal, and occipital areas related to attention, cognitive control, and sensorimotor integration. The authors interpreted this pattern as consistent with the high demands FPS games place on fast audiovisual integration and rapid action selection.
Both gaming groups also showed stronger visual-attentional connectivity than the control group. However, MOBA-related differences were more concentrated in visual-attentional networks, whereas FPS-related differences were broader and included auditory, visual, and sensorimotor systems.
Weekly Gaming Hours and Brain Networks
One of the most interesting parts of the paper is that the researchers did not stop at group comparisons. They also tested whether structural covariance could predict weekly gaming hours.
For the FPS group, the answer was yes. The prediction model showed a significant correlation between estimated and actual weekly gaming time, with a Pearson correlation of 0.34 and a 95% confidence interval from 0.26 to 0.42. The positive predictive edges were centered on the transverse temporal gyrus and extended into frontal, parietal, and occipital regions, again reinforcing the idea that long-term FPS play is linked to a broad auditory-visual-sensorimotor network.
The same predictive effect did not appear for the MOBA group. That does not mean MOBA games have no structural impact, but in this dataset their covariance matrices did not significantly predict weekly play time.
Can the Brain Patterns Distinguish Players?
The authors also used a support vector machine classifier to test whether these structural features could separate the groups. The model differentiated FPS players from controls with an area under the curve of 82.95% and from MOBA players with an area under the curve of 72.37%.
The classifier also separated MOBA players from controls with an area under the curve of 74.26%. In practical terms, this means the network patterns were distinctive enough to capture genre-related differences with moderate to strong classification performance.
What the Findings Suggest
The study supports the broader idea that different game genres are associated with different forms of cognitive plasticity. FPS games appear to be especially linked to networks involved in auditory processing, visual attention, and sensorimotor coordination, while MOBA games appear more closely tied to visual-attentional systems.
That distinction is important because it challenges the habit of treating all video games as one category. From a neuroscience perspective, an FPS and a MOBA may both be “games,” but they do not place the same cognitive demands on the player.
The authors argue that these results may have future applications in areas such as auditory-visual rehabilitation and the assessment of professional esports players. If certain genres strengthen specific network patterns, carefully designed game-based training tools could eventually be used in targeted cognitive interventions.
A Note of Caution
The paper does not claim that gaming automatically improves the brain in a simple or universal way. In fact, the authors found negative predictive edges in FPS players centered on the entorhinal cortex, a region linked to spatial memory, and they warned that heavy reliance on response-learning strategies could come at a cost to memory systems.
That is an important reminder that adaptation is not always purely beneficial. A brain may become more efficient for one set of repeated demands while becoming less reliant on other systems.
The study also has clear limitations. It was cross-sectional rather than longitudinal, so it cannot prove causation, and it included only male participants, which limits generalizability. The sample was also restricted to high-level players, meaning the results should not be automatically extended to casual gamers.
Final Thoughts
This research adds weight to the idea that long-term gaming is not neurologically uniform. FPS and MOBA players showed different structural covariance signatures, with FPS players standing out for broader auditory-visual-sensorimotor connectivity and MOBA players showing more focused visual-attentional patterns.
For readers interested in gaming, neuroscience, or esports, the biggest takeaway is simple: genre matters. The brain does not merely respond to “video games” as a single activity; it appears to adapt in ways that reflect the specific cognitive and sensory challenges built into different kinds of play.
