TL;DR: The results show that grafted cholinergic neurons, that normally do not innervate the hippocampus, can send axons and form synaptic contacts in the host hippocampus, and the ability to reinnervates the denervated hippocampal target appears to be shared by the embryologically closely related forebrain cholin allergic neuron types.

TL;DR: Results demonstrate that the corticostriatal projection, which constitutes a major source of afferent control in the normal striatum, not only extends axons into the intrastriatal striatal grafts, but also establishes synaptic connections with the implanted neuronal elements.

TL;DR: The occurrence of intrinsic serotonin-, noradrenaline- and dopamine-containing neurons in the gut of Lampetra fluviatilis deviates from the established pattern of innervation of the vertebrate intestine and is considered to be a remnant of an autonomic innervation principle common in invertebrates.

TL;DR: The results indicate that hippocampal ACh release is maintained in aged rats that exhibit severe spatial learning and memory impairments and that the septo-hippocampal cholinergic system retains its capacity to increase its A Ch release in response to both K(+)-induced depolarization and behavioral activation in the aged rat.

TL;DR: The results suggest that fimbria-fornix lesions disrupt some aspects of complex-spike place field activity, the functioning of hippocampal circuitry is influenced by fetal basal forebrain grafts, and the grafts may ameliorate the effects of lesions on spatial behaviors by influencing critical aspects of place fieldActivity in the hippocampus.
