Journal ArticleDOI
Functional specificity of local synaptic connections in neocortical networks
Ho Ko,Sonja B. Hofer,Bruno Pichler,Bruno Pichler,Katherine A. Buchanan,P. Jesper Sjöström,Thomas D. Mrsic-Flogel +6 more
TL;DR: The results reveal the degree of functional specificity of local synaptic connections in the visual cortex, and point to the existence of fine-scale subnetworks dedicated to processing related sensory information.
Journal ArticleDOI
Dendritic Excitability and Synaptic Plasticity
TL;DR: It is argued that the location of synapses in the dendritic tree, and the type of dendrite excitability associated with each synapse, play decisive roles in determining the plastic properties of that synapse.
Journal ArticleDOI
Neuronal morphometry directly from bitmap images
Tiago Ferreira,Arne V. Blackman,Julia Oyrer,Sriram Jayabal,Andrew J. Chung,Alanna J. Watt,P. Jesper Sjöström,P. Jesper Sjöström,Donald J van Meyel,Donald J van Meyel +9 more
TL;DR: The use of the Sholl Analysis software to quantify arborization directly from bitmap images correctly identified 80–86% of cells, and the utility of the method in tackling neurons that are particularly slow to reconstruct manually was explored.
Journal ArticleDOI
Neurons diversify astrocytes in the adult brain through sonic hedgehog signaling
W. Todd Farmer,Therese Abrahamsson,Sabrina Chierzi,Christopher Lui,Cristian Zaelzer,Emma V. Jones,Blandine Ponroy Bally,Gary G. Chen,Jean-François Théroux,Jimmy Peng,Jimmy Peng,Charles W. Bourque,Frédéric Charron,Frédéric Charron,Carl Ernst,P. Jesper Sjöström,Keith K. Murai +16 more
TL;DR: It is revealed that neurons actively determine the features of astrocytes in the healthy adult brain and a role for neuron-derived sonic hedgehog (Shh) in regulating the molecular and functional profile of ast rocytes is defined.
Journal ArticleDOI
Traveling waves in developing cerebellar cortex mediated by asymmetrical Purkinje cell connectivity
Alanna J. Watt,Hermann Cuntz,Masahiro Mori,Masahiro Mori,Zoltan Nusser,P. Jesper Sjöström,Michael Häusser +6 more
TL;DR: It is found that Purkinje cell axon collaterals projected asymmetrically in the sagittal plane, directed away from the lobule apex, suggesting they have a developmental role in wiring the cerebellar cortical microcircuit.
