We thank Overgaard and Kirkeby-Hinrup for examining the boundaries on the conceptual dimensions of representation developed in our Perspective (Pohl, S. et al. Clarifying the conceptual dimensions of representation in neuroscience. Nat. Rev. Neurosci. 27, 357–372 (2026))1; prompted by their questions (Overgaard, M. & Kirkeby-Hinrup, A. Boundary issues for multidimensional frameworks of representation. Nat. Rev. Neurosci.

Clarifying the conceptual dimensions of representation in neuroscience

By Stephan Pohl, Edgar Walker, David L. Barack, Jennifer Lee, Rachel N. Denison, Ned Block, Florent Meyniel, Wei Ji Ma
| Nature Verified
Abstract Despite the centrality of the notion of representation in neuroscience, the field lacks a unified framework for the concepts used to characterize representation, leading to disparate use of both terminology and the measures associated with it. To offer clarification, we propose a core set of conceptual dimensions that characterize representations in neuroscience.

Neural mechanisms of resource allocation in working memory

By Yongyong Yang, Shijing Liang, Moriah R. Arnold, Hsin-Hung Li, Wei Ji Ma, Clayton Curtis
| Science Magazine Verified
Research Article NEUROSCIENCE INTRODUCTION Working memory (WM) holds information temporarily and supports decision-making, learning, and planning. As a severely capacity-limited system, the precision of WM declines steeply as the number of items being stored increases (1–6). In addition, inherently noisy neural activity supports WM and the quality of WM representations as indexed by behavioral reports fluctuates across trials (7–14). Thus, uncertainty influences our memory-guided decisions.
