- How can cells use information from neighboring cells to improve the spatial precision of morphogen patterns? 🤔 We show that cells can gain positional information by "talking" to their neighbors - how much depends critically on spatial correlations of the patterns. buff.ly/w56OUJT
- In our recent paper on self-organized patterning, we demonstrated how the total information of a pattern is composed of positional (PI) and correlational information (CI). While PI measures local accuracy, CI is determined by the spatial correlations of a pattern. www.pnas.org/doi/10.1073/...
- Here, we ask how CI can be useful to single cell decision making, by predicting the additional PI gained when cells interact with their neighbors. Depending on the spatial correlations of the input pattern, completely different strategies to communication are required to gain information

- We propose that many current approaches are not competing ideas, but look at the same fundamental problem - egg to embryo - from different perspectives: 1️⃣ Normative theories & optimality formalize the computationa problem 2️⃣ Dynamical systems provide algorithms 3️⃣ GRNs & others model implementation
- We propose a way to organize our current thinking about the algorithmic level along a set of architectures formalizing the computational capacity and amount of lateral coupling between cells
- We provide a perspective on how this framework could help to formalize the spectrum of patterning processes from instructed to self-organized development at multiple levels.
