A Weakly Supervised U-Net Model for Precise Whole Brain Immunolabeled Cell Detection

Cell segmentation’s low precision due to the intensity differences hinders widespread use of whole brain microscopy imaging. Previous studies used ResNet or CNN to account for this problem, but are unapplicable to immunolabeled signals across samples. Here we present a semiauto ground truth generation and weakly-supervised U-Net-based Deep-learning precise segmentation pipeline for whole brain immunopositive c-FOS signals, which reveals the distinct neural activity maps with different social motivations. ### Competing Interest Statement The authors have declared no competing interest.
