Abstract
The brain modulates specific functions in its various regions. Understanding the organisation of different cells in the whole brain is crucial for investigating brain functions. Previous studies have focused on several regions and have had difficulty analysing serial tissue samples. Here, we introduce a pipeline to acquire anatomical and histological information quickly and efficiently from serial sections. First, we developed a serial brain-slice-staining method to stain serial sections, and obtained more than 98.5% of slices with high integrity. Subsequently, using the self-developed analysis software, we registered and quantified the signals of imaged sections to the Allen Mouse Brain Common Coordinate Framework, which is compatible with multimodal images and slant section planes. Finally, we validated the pipeline with immunostaining by analysing the activity variance in the whole brain during acute stress in aging and young mice. Removing the problems resulting from repeated manual operations, this pipeline is widely applicable to serial brain slices from multiple samples in a rapid and convenient manner, which benefits to facilitate research in life sciences.
