The aim of this course is to introduce Neurogenomics, covering the foundations, state of the art and outlook of the field. The perspective of the course is the multi-scale digitization that is transforming our understanding of neural structure and function, with a special focus on the bioinformatic and computational challenges of human neurobiology in health and disease. The course will thus cover the foundations of human neurodevelopmental biology all the way to the multilayered architecture of neuropsychiatric and neurological disorders, covering the range of bioinformatic and computational approaches that illuminate them and spanning the full range from single-cell multi omics to digital cognitive and behavioral phenotyping.
A unifying theme will be the reflection on innovative models in human neurobiology, intersecting the digital representation of neural function with the digitization of neural tissue enabled by the advances in programming and reprogramming that ushered in the paradigm shift of 3D in vitro models such as brain organoids. Throughout, the perspective on models will be cast through the relevant repertoire of computational analyses that make such models intelligible and integrated, including genome and epigenome sequencing, genetic association studies and eQTL, transcriptomic, proteomics, exposomics and image analysis, along with the presentation of the most relevant datasets and resources. The single cell multi-omic resolution of these layers will be a strong focus, through its revealing impact on the molecular architecture of human brain development, function and disease.

Courses of either of the "Alignment plans" of the 1st semester.
Furthermore, we expect the students to already own the following set of skills: · Concrete background of Next Generation Sequencing (available platforms , basic concepts of NGS techniques, read preprocessing and alignment) · Transcriptomics/Epigenomics fundamentals (gene quantification and differential expression analysis, peak calling, differential peak occupancy, etc.) · Basic concepts of single cell transcriptomics · Unix/BASH Command line · Base knowledge of R OR Python Programming · Statistics, Linear algebra (SUPER Optional, you tell me)
Class lectures and practices (4CFUs for frontal lessons, 2 CFUs for practical classes);
Frontal lessons will be focused on all theoretical aspects of the course, including through the in depth analysis of key papers and forum discussions in the field.
During practical classes, students will have the opportunity to use their laptop to apply methods for bulk RNASeq and ChiPSeq Data Analysis, single cell RNASeq data analysis and visualization, and apply Network Based methods for the analysis of public databases.
