- New preprint from NuttidaLab at Columbia BME 🧠✨: Neural heterogeneity shapes the temporal structure of human working memory www.biorxiv.org/content/10.1...
- 1/ Persistent activity is the classic working memory (WM) account, but continuous single-neuron firing is metabolically expensive and hard to reconcile with human cortical heterogeneity. So, we asked: can human WM be maintained without sustained single-neuron persistence?
- 2/ We analyzed an open human single-unit dataset (Kyzar et al., 2024): 902 neurons from 21 neurosurgical participants performing a Sternberg WM task. We focused on stimulus-selective “concept cells.” Thank you to the Rutishauser lab and the original authors for sharing these invaluable recordings!
