Although previous studies have already shown neuronal profiles containing various types of vesicles in neuropiles
of the central ganglia in the platyhelminths (Sukhdeo & Sukhdeo, 1990; Terenina et al., 2009; Leksonboom et al., 2012b), the present study failed to disclose any such neuronal profiles abutting on the immunopositive neurons and their proximal processes, or to disclose such aggregations of vesicles at submembranous sites of the immunopositive neuronal proximal processes on which another neuronal process abuts.
Edema of the neuropile
was observed in the ischemic zone, while there were no neurons with normal morphology in the deep-ischemic zone (Fig.
After six weeks of exposure to Mn a neuropile
exhibiting myelinic fibers with a clear disorganization of the regular pattern of myelin was observed (FIG.
The animal has a high degree of neurobiological development, as evidenced by the presence of asymmetric (excitatory) and symmetric (inhibitory) synapses, as well as the existence of glial cell processes in a wide neuropile
The space between cells that is occupied by axonal and dendrite endings is called neuropile
. Between the cortex and the brainstem are the fiber tracts (called white matter because of fatty sheathes that improve communication efficiency) that carry information in and out of the cortex, and small collections of cells called the basal ganglia -- the caudate, putamen and globus pallidus.
 reported time dependent loss of dendritic spines, necrotic like cell death, and profound alterations in the hippocampal CA1 neuropile
. Few studies have however reported progressive memory loss induced by vanadium exposure.
Structural organization of glomerular neuropile
in the olfactory and accessory lobes of an Australian freshwater crayfish, Cherax destructor.
The nerves are ganglionated, with cell bodies in the periphery of the central nerve region, or neuropile
, and extend peripheral branches that communicate with other organ systems.
Means (B-cell photoreceptor intensities minus background; unstained neuropile
regions) from each condition were tested for significance using nested ANOVA and paired Student t test comparisons (n values consisted of measures/serial-sections/block/animal/treatment).
