Working Memory: New Insights
- The brain's visual processing center is more critical to working memory than previously understood, according to a new study.
- The findings, published in Nature Communications, suggest new avenues for treating neurological and psychiatric conditions associated with working memory impairments.
- Clayton Curtis, a professor of psychology at NYU, emphasized the importance of these findings for clinical research.
New research unveils a surprising key role for the visual cortex in working memory, reshaping our understanding of how the brain functions. The early visual cortex (V1) actively maintains information,not just processes visual input as previously thought. This groundbreaking study, published in Nature Communications, suggests a distributed nature of working memory, challenging the long-held belief that the prefrontal cortex is the sole driver. Researchers disrupted neural activity in the visual cortex using TMS, finding significant impairments in visual recall. These insights could revolutionize treatments for neurological conditions like schizophrenia.News Directory 3 reports on findings that could pave the way for innovative therapies targeting memory deficits.

Study: Visual Cortex Plays Key Role in Working Memory
Updated June 16, 2025
The brain’s visual processing center is more critical to working memory than previously understood, according to a new study. While the prefrontal cortex has long been considered the primary driver of working memory—the system that allows us to temporarily hold and use information—researchers at New York University have found that the early visual cortex (V1) also plays a significant role.
The findings, published in Nature Communications, suggest new avenues for treating neurological and psychiatric conditions associated with working memory impairments. the research highlights the distributed nature of working memory and its sensitivity to changes in brain function, offering potential for improved assessment and treatment of memory-related disorders.
Clayton Curtis, a professor of psychology at NYU, emphasized the importance of these findings for clinical research. “Our results show that working memory isn’t confined to one specific brain area, but is instead distributed across multiple regions,” Curtis said.
to investigate the role of V1, Curtis and doctoral student Mrugank Dake used transcranial magnetic stimulation (TMS) to temporarily disrupt neural activity in the visual cortex of participants engaged in visual working memory tasks. The TMS created a temporary “blind spot,” and researchers observed that participants’ ability to recall visual information was impaired specifically in the affected area of the visual field.
The disruption occurred even when TMS was applied after the image had disappeared, suggesting that V1 is not only involved in processing incoming visual information but also in actively maintaining that information in memory.
“This suggests that V1 is not merely used for seeing but is also used to actively hold onto that information for future use,” Curtis explained.
Dake added,”We discovered that disrupting neural activity in V1 affects visual working memory—a surprising finding given its assumed role as only a basic processor of visual information.”
What’s next
The researchers believe these findings could lead to more effective treatments for conditions like schizophrenia, Alzheimer’s disease, and multiple sclerosis, which often involve both perceptual and working memory deficits. Future studies will likely explore how these findings can be translated into clinical applications.
