Molecular neuroscience is a discipline of neuroscience that studies molecular biology ideas applied to animal nervous systems. The scope of this subject includes molecular neuroanatomy, molecular signalling processes in the nervous system, genetics and epigenetics' impact on neuronal development, and the molecular basis for neuroplasticity and neurodegenerative disorders. The field of molecular neurobiology has recently advanced dramatically, focusing almost entirely on biological activities in individual brain cells, and it appears that many of the aims of such research will be met shortly. Integrative techniques at the genetic, molecular, cellular, and synaptic levels give crucial knowledge on the normal and pathological brain in molecular brain research, which is rapidly developing. These researches make use of a variety of cutting-edge molecular biology, genomics, proteomics, imaging, and electrophysiological approaches.
