PIK Professor Michael Platt and collaborators have generated the first single-cell “atlas” of the primate brain to help explore links between molecules, cells, brain function, and disease.
Learning about resilience to stress
PURM students spent the summer researching the neurobiology of stress resilience in the lab of Seema Bhatnagar, anesthesiology and critical care professor in the Perelman School of Medicine.
How the hippocampus distinguishes true and false memories
Researchers in the School of Arts & Sciences have shown for the first time that electrical signals in the hippocampus differ immediately before recollection of true and false memories.
Decoding acoustic objects
Third-year student Lily Wei spent the summer conducting research in the lab of Vijay Balasubramanian using algorithms to propose how the brain may recognize acoustic objects.
An unsolved mystery: Why are we sleepy when sick?
David Raizen, a professor of neurology, alongside PURM student Hina Sako, spent the summer moving forward research examining how sickness affects sleep.

The brain may interpret smells from each nostril differently
A study by postdoc Gulce Nazli Dikecligil in the Perelman School of Medicine suggests that the smells flowing through each nostril are processed as two separate signals in the part of the brain that receives smell inputs.
