A Silent Spinal Pathway Awakens in Chronic Pain
August 20, 2025
New research reveals that acute and chronic insults both reshape how pain signals are sent to the brain, but through distinct mechanisms. By using long-term calcium imaging in mice, researchers from the Woolf lab tracked the same spinal cord neurons over time and found that acute pain temporarily increases sensitivity, while chronic nerve injury recruits a previously ‘silent’ group of neurons – offering a potential key to understanding chronic pain.

While learning a typing task, epilepsy patients got faster after brief rest breaks rather than while typing. There was a corresponding increase in hippocampal ripple rate that predicted these offline gains in speed.

Bryan Baxter and Dara Manoach share a new study on the brain basis of motor learning. When learning a typing task, epilepsy patients show higher rates of “hippocampal ripples”--an electrical activity pattern in the brain associated with memory formation--during brief rest breaks than during the typing itself. These ‘offline’ ripples predict gains in speed, suggesting that ripples contribute to motor learning during wakeful rest.

It was long thought that only neurons in the outermost regions of the brain, called the cortex, could adapt and change their properties in response to visual experience. Takuma Sonoda and Chinfei Chen share new findings revealing that the visual thalamus, a structure in the center of the brain, at an earlier stage in the visual pathway than the cortex, can also change based on what animals see. Their discovery expands our understanding of how sensory systems learn and adapt.

The new center, supported by a gift to Harvard University from philanthropist K. Lisa Yang, will bring together scientists working to demystify brain-body communication. The center is part of the Yang Tan Collective, which includes six research centers at MIT and two at HMS. The collective brings together top scientists and fellows in a focused, collaborative community that aims to turn fundamental discoveries into solutions that improve quality of life.

For years, people with paralysis have used brain-computer interfaces to turn neural signals into actions by thinking about the actions they would like to take: typing words, controlling robotic arms, and producing speech. A new study shows that the interfaces could translate not only intended speech, but internal thoughts as well. A new study examines the representation of inner speech in motor cortex and its implications for speech neuroprostheses.
