results the results showed that bbb test showed an improvement in the cr, while the quantitative analysis showed that the improvement rate was higher in the rats treated with cnl than those treated with bmscs only or the untreated animals, similar results were noticed in the improvement index. immunohistochemical analysis of the tissue section prepared from the cr showed that the transplanted c...
The neuronal diversity in our brains is staggering. Understandably, uncovering the molecular rules that govern it is a very difficult pursuit. Its starting point should most certainly be a catalogue raisonné of this diversity, ordered perhaps according to the relatively few neurotransmitters employed in the nervous system. Historically, this has been achieved in descriptive studies; first using...
The basal forebrain cholinergic innervation of the medial prefrontal cortex (mPFC) is crucial for cognitive performance. However, little is known about the organization of connectivity between the basal forebrain and the mPFC in the mouse. Using focal virus injections inducing Cre-dependent enhanced yellow fluorescent protein expression in ChAT-IRES-Cre mice, we tested the hypothesis that there...
BACKGROUND Indirect evidence supports a role of spinal cholinergic neurons in tonically reducing response to noxious mechanical stimulation and in effecting analgesia from alpha2-adrenergic agonists. This study directly assessed the role of cholinergic neurons in regulating the level of mechanical allodynia and in participating in the antiallodynic effect of the clinically used alpha2-adrenergi...
Nerve growth factor (NGF), acting via the TrkA receptor, has been shown to regulate the survival and maturation of specific neurons of the peripheral nervous system. Furthermore, exogenous NGF has potent actions on TrkA-expressing cholinergic neurons of the basal forebrain (BFCNs) and striatum. However, initial analysis of mice lacking NGF or TrkA revealed that forebrain cholinergic neurons wer...
Alzheimer's Disease (AD) is a neurodegenerative disorder that is characterized by extracellular deposits of amyloid-beta peptide (Abeta) and a severe depletion of the cholinergic system, although the relationship between these two events is poorly understood. In the neocortex, there is a loss of cholinergic fibers and receptors and a decrease of both choline acetyltransferase (ChAT) and acetylc...
The basal forebrain (BF) contains a heterogeneous population of cholinergic and non-cholinergic corticopetal neurons and interneurons. Neurons firing at a higher rate during fast cortical EEG activity (f>16Hz) were called F cells, while neurons that increase their firing rate during high-amplitude slow-cortical waves (f<4Hz) were categorized as S-cells. The prefrontal cortex (PFC) projects heav...
