Investigations into a bioelectric component of synaptogenesis
Brain Research, 1984Synaptogenesis has been investigated in the electric organ of Torpedo marmorata with the objective of determining whether a bioelectric effect could be demonstrated. Answers to 3 questions were sought. (1) Are currents and/or fields present within the organ? (2) Can they be localized? (3) Are they involved with the synaptogenic process?

Watching Synaptogenesis in the Adult Brain
Annual Review of Neuroscience, 2010Although the lifelong addition of new neurons to the olfactory bulb and dentate gyrus of mammalian brains is by now an accepted fact, the function of adult-generated neurons still largely remains a mystery. The ability of new neurons to form synapses with preexisting neurons without disrupting circuit function is central to the hypothesized role of ...

Motoneuron differentiation, survival and synaptogenesis
Current Opinion in Genetics & Development, 1997The motoneuron is the central neuron whose development is best understood. Recent research has provided much new information about the molecules involved in aspects of motoneuron development first outlined by classic embryology studies. Over the past year, progress has been particularly apparent in the following areas: motoneuron induction and control ...

Peripheral synaptogenesis in nerve parabiosis
Journal of Comparative Neurology, 1969AbstractOne hundred and ninety‐two rats were parabiotically coupled to test regeneration of the sciatic nerve of the “donor” rat in the denervated gastrocnemius of the “host.”.Proliferation of the implanted nerve was clearly demonstrated after 30 days.

Dendritic arbor development and synaptogenesis
Current Opinion in Neurobiology, 2001In vivo studies indicate that synaptic activity promotes dendritic arbor elaboration at early stages of brain development. At later stages of development, synaptic activity stabilizes dendritic structure. The different roles of synaptic activity with respect to structural plasticity probably reflect the regulated spatiotemporal expression of key ...

Synaptogenesis in the basilar papilla of the chick
Journal of Neurocytology, 1978Synaptogenesis was studied in the basilar papilla of chicken embryos from days 7--21 of incubation. On the 9th day of incubation differentiating hair cells first appeared and a few growing nerve tips made contact with them, although no membrane specializations were apparent at this stage.
