WebGlial cells are fundamental players in the central nervous system (CNS) development and homeostasis, both in health and disease states. In Parkinson’s disease (PD), a dysfunctional glia-neuron crosstalk represents a common final pathway contributing to the chronic and progressive death of dopaminergic (DAergic) neurons of the substantia nigra pars … WebWith invertebrates, ganglia often do the work of a brain. Eg The earthworm has a ganglion above the gut at the front. This is linked to another under the gut by nerve fibres running down each side of the gut. The rest of the central nervous system runs under the gut.
