Channelrhodopsin-2–assisted circuit mapping of long-range callosal projections

L Petreanu, D Huber, A Sobczyk, K Svoboda - Nature neuroscience, 2007 - nature.com
The functions of cortical areas depend on their inputs and outputs, but the detailed circuits
made by long-range projections are unknown. We show that the light-gated channel …

NMDA receptor subunit-dependent [Ca2+] signaling in individual hippocampal dendritic spines

A Sobczyk, V Scheuss, K Svoboda - Journal of Neuroscience, 2005 - Soc Neuroscience
Ca 2+ influx through synaptic NMDA receptors (NMDA-Rs) triggers a variety of adaptive
cellular processes. To probe NMDA-R-mediated [Ca 2+ ] signaling, we used two-photon …

A Sobczyk - Bulletin of the American Mathematical Society, 1941 - community.ams.org
In a paper in the Duke Journal, AE Taylor1 remarks that it is an open question whether or not
there exists a projection of the space (m) y of bounded sequences, on its subspace (c0), the …

Supersensitive Ras activation in dendrites and spines revealed by two-photon fluorescence lifetime imaging

R Yasuda, CD Harvey, H Zhong, A Sobczyk… - Nature …, 2006 - nature.com
To understand the biochemical signals regulated by neural activity, it is necessary to measure
protein-protein interactions and enzymatic activity in neuronal microcompartments such as …
