Neonatal stroke in mice causes long-term changes in neuronal notch-2 expression that may contribute to prolonged injury

Albéri, Lavinia ; Chi, Zhikai ; Kadam, Shilpa D. ; Mulholland, Justin D. ; Dawson, Valina L. ; Gaiano, Nicholas ; Comi, Anne M.

In: Stroke, 2010, vol. 41, no. Suppl. 1, p. S64-S71

Background and Purpose: Notch receptors (1–4) are membrane proteins that, on ligand stilumation, release their cytoplasmic domains to serve as transcription factors. Notch-2 promotes proliferation both during development and cancer, but its role in response to ischemic injury is less well understood. The purpose of this study was to understand whether Notch-2 is induced after neonatal stroke...

Developmental regulation of expression of schizophrenia susceptibility genes in the primate hippocampal formation

Favre, Guillaume ; Banta Lavenex, Pamela A. ; Lavenex, Pierre

In: Translational Psychiatry, 2012, vol. 2, p. e173

The hippocampal formation is essential for normal memory function and is implicated in many neurodevelopmental, neurodegenerative and neuropsychiatric disorders. In particular, abnormalities in hippocampal structure and function have been identified in schizophrenic subjects. Schizophrenia has a strong polygenic component, but the role of numerous susceptibility genes in normal brain development...

Quantitative analysis of postnatal neurogenesis and neuron number in the macaque monkey dentate gyrus

Jabès, Adeline ; Banta Lavenex, Pamela A. ; Amaral, David G. ; Lavenex, Pierre

In: European Journal of Neuroscience, 2010, vol. 31, no. 2, p. 273-285

The dentate gyrus is one of only two regions of the mammalian brain where substantial neurogenesis occurs postnatally. However, detailed quantitative information about the postnatal structural maturation of the primate dentate gyrus is meager. We performed design-based, stereological studies of neuron number and size, and volume of the dentate gyrus layers in rhesus macaque monkeys (Macaca...

Postnatal development of the hippocampal formation: A stereological study in macaque monkeys

Jabès, Adeline ; Banta Lavenex, Pamela A. ; Amaral, David G. ; Lavenex, Pierre

In: The Journal of Comparative Neurology, 2011, p. -

We performed a stereological analysis of neuron number, neuronal soma size, and volume of individual regions and layers of the macaque monkey hippocampal formation during early postnatal development. We found a protracted period of neuron addition in the dentate gyrus throughout the first postnatal year and a concomitant late maturation of the granule cell population and individual dentate...

Intrinsic connections of the macaque monkey hippocampal formation: I. Dentate gyrus

Kondo, Hideki ; Lavenex, Pierre ; Amaral, David G.

In: The Journal of Comparative Neurology, 2008, vol. 511, no. 4, p. 497 - 520

We have carried out a detailed analysis of the intrinsic connectivity of the Macaca fascicularis monkey hippocampal formation. Here we report findings on the topographical organization of the major connections of the dentate gyrus. Localized anterograde tracer injections were made at various rostrocaudal levels of the dentate gyrus, and we investigated the three-dimensional organization of the...
