AI Applications in Neuroscience

Collaborative innovation combining AI with neuropsychology is proving to be transformative. Six research clusters show specific value and potential: 🌱 Neuroscience and Mental Health: Understanding mental health through neuroimaging and machine learning enables earlier, more precise interventions for conditions like ADHD and depression. By examining correlations in brain function, this research helps identify key markers for cognitive impairments, aiding in early diagnosis and personalized treatment plans. 🔍 Computational Modeling: Computational models simulate decision-making and cognitive markers, which are crucial for neurological conditions like epilepsy. Machine learning applied to seizure detection, for instance, offers a potential breakthrough in predicting and managing epilepsy, helping patients gain better control and care. 🧠 Cognitive Neuroscience: Studies of cognitive decline and neurodegenerative diseases, such as Alzheimer’s, benefit from reinforcement learning models that reveal patterns in brain degeneration. These insights are essential for developing strategies to slow disease progression, offering hope for more effective interventions. 💡 Cognitive Neurology and Neuropsychology: Examining cognitive functions through neuroimaging and machine learning provides deeper insights into disorders like aphasia and neurocognitive deficits. By mapping brain functions and assessing structural changes, these studies advance our understanding of how specific neurological impairments affect behavior and cognition. 💗 Neuropsychological Features: Machine learning models predict mental health outcomes and cognitive declines by analyzing attention and processing speed. This focus on prediction and prevention, especially for conditions like cardiovascular disease impacting cognition, enables proactive care and lifestyle adjustments to mitigate risks. ⚙️ Neurodegenerative Conditions: AI-based predictive models for neurodegenerative diseases like Parkinson’s allow for early, more accurate diagnoses. By analyzing markers in social cognition and emotional processing, this cluster supports personalized interventions, helping to maintain patient quality of life and reduce care burdens. This is only the beginning. This field is absolutely ripe for rapid advance and massive real-world value.

AI is getting closer to accessing the one thing we’ve always considered private: your thoughts. Recent advances in neuro-AI can now identify whether a person recognizes specific information using EEG signals. A 2025 study using deep-learning reached 86.7% accuracy in detecting recognition through the P300 brain wave: a response triggered before conscious awareness. Meanwhile, some jurisdictions are already experimenting with this technology. 🇮🇳 India has used brain-mapping techniques in hundreds of criminal investigations, showing just how quickly neuroscience can enter real-world decision systems. But the implications go beyond law enforcement. AI models can now (fMRI + diffusion models): Reconstruct visual experiences directly from brain activity ✔️ Models that reconstruct what you’re seeing — in near real-time — based solely on your brain activity (Think: AI generating the images your eyes are looking at.) Decode unspoken language in early experimental settings ✔️ Models that reconstruct the words you’re thinking, even if you never speak A 2023–2024 wave of studies using fMRI + LLMs demonstrated the ability to decode semantic meaning of inner speech—turning thoughts into text-like outputs. This raises critical questions for business leaders, policymakers, and innovators: How do we prepare for a world where cognitive data becomes a new category of sensitive information? What safeguards, standards, and governance frameworks will protect mental privacy as neuro-AI scales? The technology is advancing faster than the regulations around it and the organisations that understand this early will be better positioned to navigate what comes next. #AI #Neuroscience #Innovation #Leadership #Ethics #FutureOfWork Reference: Kim, S., Cheon, J., Kim, T., Kim, S.

Some research projects are just cool. Meta’s AI lab has created a system that can predict how your brain will respond when you watch a movie, not in a vague way, but down to the second, across different regions of your cortex. It is a leap forward for neuroscience and it just earned Meta first place in one of the most competitive brain modelling contests in the world. The winning system is called TRIBE, short for TRImodal Brain Encoder. It was built to compete in the Algonauts 2025 Challenge, an annual event where teams from around the globe race to design the most accurate computer models of the human brain. The challenge is run by the Algonauts Project, launched in 2019 to bring neuroscientists and AI researchers together in open competition. The aim is to push forward our understanding of how biological and artificial intelligence work, using shared datasets and transparent methods. The Algonauts Project is inspired by the idea that comparing brains and AI models could reveal what makes intelligent systems efficient, robust and trustworthy. It promotes faster innovation by using algorithms to test theories about the brain, fosters collaborative science by encouraging open sharing of methods, and is designed to expand across disciplines as the community grows. Meta’s team trained TRIBE on one of the richest brain datasets ever assembled, more than 80 hours of high-resolution fMRI brain scans per person, recorded while participants watched TV shows and films ranging from Friends to The Bourne Supremacy. For each moment of footage, TRIBE analysed three streams of information. These streams were synchronised in time and fed into a transformer model that learned how the brain integrates them. TRIBE won by a clear margin over more than 260 competing teams. It explained more than half of the explainable variation in brain responses, a high benchmark in neuroscience. The biggest performance gains came from using all three modalities, text, sound and vision, mirroring the way human perception combines sensory inputs. In association areas of the brain, the multimodal approach delivered up to 30 percent better predictions than any single modality model. For people, the immediate impact is not that Meta can read your mind, because it cannot. But it shows that AI is getting better at modelling how the brain processes complex, real-world information. In time, tools like TRIBE could support better diagnostics for conditions that affect language or sensory processing, create more engaging and accessible entertainment, or adapt education to the way an individual’s brain responds to material. TRIBE offers a way to study how language, vision and sound are combined in real time across the cortex, and it could help unify previously separate strands of neuroscience research. By showing that a single, non-linear, multimodal model can predict whole-brain responses, it also points to the possibility of more integrated models of cognition in the years ahead.

Using AI, your phone or smartwatch may detect Parkinson’s or Alzheimer’s years before a clinical diagnosis. ⌚️🩺 In our new Nature Reviews Bioengineering paper, we examine how digital biomarkers from everyday technologies can measure brain health continuously rather than only during clinic visits. Paper Link 🔗: https://lnkd.in/gwnjvPkE Paper PDF 🗒️: https://rdcu.be/ffDk2 These signals already capture changes in movement, behavior, physiology, and environment. Parkinson’s stands out because its motor symptoms are directly measurable with everyday sensors, which has accelerated validation. The harder problem is validation, since clinical standards are defined in controlled settings while these signals are collected in daily life. Even relatively simple measures have taken years to reach clinical acceptance. Regulation is starting to adapt, with emerging validation and reporting frameworks, but it is still early. The bigger shift is economic. Reimbursement is moving toward remote and continuous monitoring through RPM and RTM pathways (e.g., CPT 99453/99454/99457; 98975–98977, 98980), but these are still structured around episodic care. This leaves an open question of how continuous, longitudinal signals fit into billing structures defined by time and discrete interactions. While DBMs can greatly expand brain health access to underserved populations, they must be validated across diverse populations and should not assume everyone has the same technologies, connectivity, or digital literacy. What is getting really exciting is the combination of new sensing and more personalized models. Smart fabrics, BCIs, molecular signals from sweat and breath, and miniaturized implantables are beginning to integrate with models that learn each individual’s baseline. This makes it possible to track how the disease evolves at the level of the individual.

🧠 Are we rediscovering the brain through AI? I’m excited to share our new paper just published in Computers in Biology and Medicine (Volume 204, March 2026, 111533) introducing ELSA (Emergent Language Symbolic Autoencoder): a weakly supervised framework for hierarchical modeling and labeling of intrinsic functional brain networks https://lnkd.in/gSK73-RY. 🤖 The bigger question for NeuroAI If CNNs learn through hierarchical local features, and Transformers through dynamic routing and long-range interactions… what is the brain doing when it coordinates distributed functional networks across scales? Are we uncovering shared computational principles (hierarchy, routing, compression) or are modern architectures simply powerful metaphors for biology? And if there is a real parallel, is it closer to message passing, attention-like gating, predictive coding, energy minimization, or something we haven’t named yet? 🧬 Why this matters We still don’t fully understand how the brain organizes and reconfigures functional systems. These networks are hierarchical, overlapping, and dynamic, not flat categories. In neuroscience, models matter not just for prediction but for mechanistic insight. For clinical translation, interpretability is essential: models should help us reason about brain organization, not only predict outcomes. 🧩 What this work does 🧠 Uses resting-state fMRI data to study the hierarchical organization of intrinsic functional brain networks 🤖 Trains ELSA, a weakly supervised symbolic autoencoder, to learn multilevel network structure from neuroimaging signals 🔤 Links learned clusters to symbolic “sentences” to support interpretability 📐 Introduces a generalized hierarchical loss to encourage consistency across levels of organization 📊 Evaluates performance using a hierarchical consistency metric (>97% in the best-performing configuration) 💻 Code & resources: https://lnkd.in/g-mTGG3q 🙏 Grateful to Dr. Haris Sair for his leadership and collaboration throughout this work. Deep thanks as well to Ammar Ahmed, Craig Jones, and to the teams at The Johns Hopkins University School of Medicine and Johns Hopkins Malone Center for Engineering in Healthcare. Collaborating with such an exceptional group, bringing together clinical insight, engineering rigor, and scientific curiosity, has been truly inspiring. #NeuroAI #ComputationalNeuroscience #fMRI #BrainNetworks #Interpretability #DeepLearning #MedicalImaging #MedicalImaging #MicrosoftAI #AzureAI #AIforHealthcare #JohnsHopkins

🧠 New preprint from our group! Two of my lab’s talented PhD students, Yu Duan & Hamza Tahir Chaudhry, introduce POCO: a tool for predicting brain activity at the cellular and network level during spontaneous behavior. Check out the full paper: https://lnkd.in/eX-zdP6k To build POCO, we trained it on neural imaging from zebrafish, mice, and C. elegans during both spontaneous and task-driven behaviors. POCO’s architecture combines a local forecaster (modeling neuron-level dynamics) with a population encoder (capturing global patterns), allowing it to predict how each neuron evolves and how it’s influenced by broader brain dynamics. After training and predicting on multi-species, multi-behavior datasets, POCO was able to successfully: ➡️ Forecast brain activity ~15 seconds into the future, across species and behaviors ➡️ Adapt to new data with minimal fine-tuning—potentially enabling real-time applications ➡️ Independently derive brain region clusters without anatomical labels, based on neural activity alone ➡️ Outperform simpler models on real, context-rich data, showing better prediction accuracy rather than a performance decline with exposure to longer, more variable data. Based on these results, POCO offers enormous potential as a tool for neuroscience research and closed-loop neurotechnologies. Its ability to predict spontaneous brain activity across sessions & species opens new doors for understanding the brain & developing next-gen neural interfaces—with potential applications in brain-machine interfaces, cognitive modeling, and spontaneous behavior analysis. Congrats to Yu & Hamza, and thank you to our collaborators Karl Deisseroth, Misha Ahrens, Chris Harvey, as well as the Kempner Institute at Harvard University and Harvard Medical School for their support. 📄 Read the full paper: https://lnkd.in/eX-zdP6k 💻 Try the open source code: https://lnkd.in/edFR2APe #NeuroAI #ComputationalNeuroscience #Neurotech

A new 2025 article by Dr. José Valerio in Brain Sciences shows us how the OR and clinic are about to get 'a lot smarter.' Will DBS and neuromodulation become so complex it will become inaccessible to most people around the world? Enter AI. Artificial intelligence or AI is no longer a distant dream in the field of neurosurgery. It’s here, and reshaping how we deliver deep brain stimulation (DBS) and neuromodulation for Parkinson’s and other diseases. Key Points: - There will need to be precision target selection for brain surgeries and AI is a great tool to aid that challenge. - AI-powered neuroimaging tools will pinpoint the exact regions of the brain to stimulate thus reducing time and guesswork. The hope is that it will also improve surgical outcomes. - DBS programming will become personalized. AI can analyze brain signals in real time and adapt stimulation settings to an individual’s unique brain patterns and symptom fluctuations. - We will perform predictive modeling of outcomes. Machine learning models are being trained on thousands of cases to predict response; even before a surgery. - There will be closed-loop DBS systems, at least for some. AI is enabling fully adaptive systems that automatically adjust stimulation on symptoms or on neural feedback. Think of it as a smart thermostat for the brain. - These tools are being expanded to other conditions including epilepsy, depression, OCD, addiction and chronic pain. My take: Here are the points that resonated w/ me. 1- AI is making brain surgery safer and smarter. 2- Every brain is different and AI can help us w/ that fundamental challenge. 3- Time to throw away one-size-fits-all approaches. 4- If it improves your outcome, why not employ a smart device to listen to your brain and adjust automatically. Doesn't your smartwatch already do something similar? 5- How cool is it if one day AI predicts how well DBS will work, even before the first surgical incision. I know AI is scary but isn't helping persons w/ disease and their healthcare teams make more confident decisions in everyone's best interest? Sleep on this fact: This isn’t just the future, it’s happening now. If we don't learn how to apply AI, we risk the complexity of the 'new devices' outpacing our ability to manage those who need them. https://lnkd.in/eGsZfW8e Parkinson's Foundation Norman Fixel Institute for Neurological Diseases
