This volume explores multiple methods and approaches used to generate human brain and neuroretinal organoids to address fundamental questions in human brain research. The chapters in this book cover topics such as self-organizing brain organoids with ventricles amenable to injection and electroporation; visualization of 3D organoids though the latest advancements in microscopy; generation of 3D retinal tissue with physiologically competent, light-sensitive photoreceptors; modeling brain tu...
