How the brain, made up of billions of specialized cells, weighs evidence and makes split-second decisions has long been a mystery. A new study led by Princeton University researchers finds that, despite complex and varied activity among individual neurons, their behavior is shaped by a shared structure that helps the brain reach a unified choice.

The Princeton Neuroscience Institute celebrated the Class of 2025 Neuroscience (NEU) majors during its annual Class Day Ceremony on May 26, 2025. The event brought together seniors, their families and friends, and PNI faculty to honor the accomplishments and academic journeys of this year's cohort of graduating neuroscience students.

Congratulations to Ammon Love, a neuroscience minor at Princeton, who was recently named an Udall Scholar! The nationwide Udall Foundation awards scholarships to college sophomores and juniors “committed to careers in the environment, Tribal public policy or Native health care.” Love is majoring in the School of Public and International Affairs…

Four Princeton University faculty members have been selected as recipients of the 2025 Graduate Mentoring Awards, including PNI associated professor Elizabeth Margulis.

Two members of the Princeton Neuroscience Institute community were recognized for their outstanding ability to communicate complex research during Princeton Research Day 2025: undergraduate Jeffrey Chen '25 and graduate student Serene Dhawan.

Congratulations to associated faculty member William Bialek, who was elected to the American Academy of Arts and Sciences!

Congratulations to PNI's Director Mala Murthy, who was awarded a 2024 Pilot Award from…

After nine years of painstaking work, an international team of researchers, co-led by PNI’s Sebastian Seung, published a…

Congratulations to Augustin Hennings, a postdoctoral fellow working in the labs of PNI professors Yael Niv and Kenneth Norman, on being awarded a prestigious two-year National Research Service Award from the National Institute of Mental Health. His research tackles a fundamental challenge in anxiety treatment: why symptoms often return after…

We've all been there: one bad oyster ruins seafood forever. Now, Princeton neuroscientists have pinpointed how the brain stores memories for these powerful food aversions in mice. The new results reveal how “one-shot learning”, where a single experience creates lasting memories, unfolds in rodents, which might shed light on how similar memories form in people, such as how a single traumatic event can lead to PTSD.

The Princeton Neuroscience Network (PNN) was excited to host the Princeton Regional Brain Bee for the fifth year on February 15, 2025. This competition is the first step in an international event testing…
