J Neurophysiol
. 2006 Nov;
97(3):2130-47.
PMID: 17122325
Chronic stimulation of a mystacial whisker follicle for 24 h induces structural and functional changes in layer IV of the corresponding barrel, with an insertion of new inhibitory synapses on...

PLoS Biol
. 2006 Oct;
4(11):e343.
PMID: 17048987
Astrocytes play a major role in the removal of glutamate from the extracellular compartment. This clearance limits the glutamate receptor activation and affects the synaptic response. This function of the...

J Neurosci
. 2006 Sep;
26(39):10057-67.
PMID: 17005869
Barrelless mice (BRL) homozygous for the BRL mutation that disrupts the gene coding for adenylyl cyclase type I on chromosome 11 lack spatial segregation of layer IV cortical cells and...

Knott G, Holtmaat A, Wilbrecht L, Welker E, Svoboda K
Nat Neurosci
. 2006 Aug;
9(9):1117-24.
PMID: 16892056
Dendritic spines appear and disappear in an experience-dependent manner. Although some new spines have been shown to contain synapses, little is known about the relationship between spine addition and synapse...

Holtmaat A, Wilbrecht L, Knott G, Welker E, Svoboda K
Nature
. 2006 Jun;
441(7096):979-83.
PMID: 16791195
Functional circuits in the adult neocortex adjust to novel sensory experience, but the underlying synaptic mechanisms remain unknown. Growth and retraction of dendritic spines with synapse formation and elimination could...

Croquelois A, Bronchti G, Welker E
Eur J Neurosci
. 2005 May;
21(7):1798-806.
PMID: 15869475
To study the degree and time course of the functional recovery in the somatosensory cortex (SI) after an excitotoxic lesion in the adult mouse thalamus, metabolic activity was determined in...

Chattopadhyaya B, Di Cristo G, Higashiyama H, Knott G, Kuhlman S, Welker E, et al.
J Neurosci
. 2004 Oct;
24(43):9598-611.
PMID: 15509747
The neocortical GABAergic network consists of diverse interneuron cell types that display distinct physiological properties and target their innervations to subcellular compartments of principal neurons. Inhibition directed toward the soma...

Di Cristo G, Wu C, Chattopadhyaya B, Ango F, Knott G, Welker E, et al.
Nat Neurosci
. 2004 Oct;
7(11):1184-6.
PMID: 15475951
Distinct classes of GABAergic synapses target restricted subcellular domains, thereby differentially regulating the input, integration and output of principal neurons, but the underlying mechanism for such synapse segregation is unclear....

Vyazovskiy V, Welker E, Fritschy J, Tobler I
Eur J Neurosci
. 2004 Sep;
20(5):1363-70.
PMID: 15341608
Regional differences in EEG slow wave activity (SWA) during sleep after sleep deprivation (SD) may be a consequence of differential metabolic activation of cortical areas. We investigated the relationship between...

J Neurosci
. 2004 Mar;
24(10):2394-400.
PMID: 15014114
Increased sensory stimulation in the adult whisker-to-barrel pathway induces the expression of BDNF as well as synapse formation in cortical layer IV. Here, we investigated whether BDNF plays a role...
