Summary: A new research suggests that integrating Large Language Models (LLMs) like ChatGPT into neuroscience has the potential to revolutionize studies by analyzing extensive datasets. The study highlights how LLMs can facilitate communication between different neuroscience fields, accelerating discoveries in areas such as neurodegeneration drug development. While recognizing the challenges of understanding AI-derived insights, the authors advocate for a cultural shift towards embracing AI in research, emphasizing the ability of LLMs to synthesize knowledge from vast data, potentially surpassing human comprehension, but driving clinical advancements.
Key Facts:
- LLMs have the potential to interpret and analyze neuroscientific data across various domains, offering insights that may exceed human analysis.
- Collaboration between LLMs in different neuroscience areas could lead to groundbreaking discoveries, such as identifying new molecules for neurodegeneration treatment.
- Realizing LLMs’ full potential in neuroscience requires significant infrastructure investment and a shift towards a more data-driven scientific approach.

The ability of these models to interpret and produce human text sources (and other sequence data) has implications for people in many areas of human activity. A new perspective paper in the journal Neuron argues that like many professionals, neuroscientists can either benefit from partnering with these powerful tools or risk being left behind. In their previous studies, the authors demonstrated that important preconditions are met to develop LLMs that can interpret and analyze neuroscientific data like ChatGPT interprets language. These AI models can be built for many different types of data, including neuroimaging, genetics, single-cell genomics, and even hand-written clinical reports. The traditional model of research involves scientists studying previous data on a topic, developing new hypotheses, and testing them using experiments. Given the massive amounts of data available, scientists often focus on a narrow field of research, such as neuroimaging or genetics. LLMs, however, can absorb a more comprehensive range of neuroscientific research than a single human ever could. The authors argue that one day, LLMs specialized in diverse areas of neuroscience could communicate with each other to bridge siloed areas of neuroscience research, uncovering truths that would be impossible to find by humans alone. For example, an LLM specialized in genetics could be used along with a neuroimaging LLM in drug development to discover promising candidate molecules to stop neurodegeneration. The neuroscientist would direct these LLMs and verify their outputs. Lead author Danilo Bzdok acknowledges the possibility that the scientist may not always fully understand the mechanism behind the biological processes discovered by these LLMs. “We have to be open to the fact that certain things about the brain may be unknowable, or at least take a long time to understand,” he says. “Yet we might still generate insights from state-of-the-art LLMs and make clinical progress, even if we don’t fully grasp the way they reach conclusions.” To realize the full potential of LLMs in neuroscience, significant infrastructure for data processing and storage is needed, along with a shift towards a more data-driven scientific approach, where studies that heavily rely on artificial intelligence and LLMs are published by leading journals and funded by public agencies. While the traditional model of strongly hypothesis-driven research remains key and is not disappearing, capitalizing on emerging LLM technologies might be important to spur the next generation of neurological treatments where the old model has been less fruitful. “Our ability to generate biomolecular data is eclipsing our ability to glean understanding from these systems. LLMs offer an answer to this problem. They may be able to extract, synergize and synthesize knowledge from and across neuroscience domains, a task that may or may not exceed human comprehension.”
