Bidirectional global spontaneous network activity precedes the canonical unidirectional circuit organization in the developing hippocampus.

Shi Y1, Ikrar T, Olivas ND, Xu X.
The Journal of comparative neurology.J Comp Neurol.2014 Jun 15;522(9):2191-208. doi: 10.1002/cne.23528.
Spontaneous network activity is believed to sculpt developing neural circuits. Spontaneous giant depolarizing potentials (GDPs) were first identified with single-cell recordings from rat CA3 pyramidal neurons, but here we identify and characterize a large-scale spontaneous network activity we term g

Mossy fiber-evoked subthreshold responses induce timing-dependent plasticity at hippocampal CA3 recurrent synapses.

Brandalise F1, Gerber U.
Proceedings of the National Academy of Sciences of the United States of America.Proc Natl Acad Sci U S A.2014 Mar 18;111(11):4303-8. doi: 10.1073/pnas.1317667111. Epub 2014 Feb 18.
Dentate granule cells exhibit exceptionally low levels of activity and rarely elicit action potentials in targeted CA3 pyramidal cells. It is thus unclear how such weak input from the granule cells sustains adequate levels of synaptic plasticity in the targeted CA3 network. We report that subthresho

Selective presence of a giant saccular organelle in the axon initial segment of a subpopulation of layer V pyramidal neurons.

Antón-Fernández A1, Rubio-Garrido P, Defelipe J, Muñoz A.
Brain structure & function.Brain Struct Funct.2013 Dec 21. [Epub ahead of print]
Recently it has been shown that a giant saccular organelle (GSO) of unknown function is present in the axon initial segment (AIS) of an uncharacterized population of pyramidal cells of the rodent neocortex. Using tract-tracing methods and immunocytochemistry, in the present study we show that in rod
