Genetic Diversity of Principal Neurons in the Hippocampus
... Since neurons and their processes are densely packed in the nervous system, little information about individual neurons can be obtained if all of them are labeled. This has led to efforts to analyze smaller subsets of neuronal populations. The first successful method was discovered by Camillo Golgi ...
