In contrast to previous post-mortem or fixed tissue histochemical reports, live calcium and mitochondrial imaging data suggest that the enteric nervous system is not generally affected in Parkinson's disease patients.
Although central nervous system (CNS) regeneration has been considered to be controlled by CNS microenvironment, CNS injury causes leading to leakage of circulating factors into CNS, which promotes CNS regeneration.
Mapping individual neural stem cells to their corresponding embryonic and postembryonic progeny shows that these sets of neurons have profound molecular and anatomical similarities despite building different central nervous systems.
A newly identified component in the architecture of the axon/myelin-unit – the septin/anillin scaffold – maintains the structure of myelin in the central nervous system, thereby preventing myelin outfoldings.
Analyzing a map of all cholinergic neurons in the nematode C. elegans shows how these neurons are embedded in the C. elegans connectome and reveals the regulatory factors controlling their development.
