Electrical stimulation of locus coeruleus strengthens the surround inhibition in layer V barrel cortex in rat

S Motaghi, V Sheibani, R Farazifard, H Joneidi - Neuroscience letters, 2006 - Elsevier
It is believed that locus coeruleus (LC) influences the sensory information processing.
However, its role in cortical surround inhibitory mechanism is not well established. In this …

The role of cortical activity in experience-dependent potentiation and depression of sensory responses in rat barrel cortex

H Wallace, S Glazewski, K Liming… - Journal of …, 2001 - Soc Neuroscience
The role of cortical activity in experience-dependent cortical plasticity was studied in the rat
barrel cortex. Plasticity was induced by depriving every other whisker in a chessboard …

Collateral projection from the locus coeruleus to whisker‐related sensory and motor brain regions of the rat

SB Lee, SK Beak, SH Park… - Journal of …, 2009 - Wiley Online Library
The primary goal of this study was to examine whether the locus coeruleus (LC) provides
collateral projections to whisker‐related, sensorimotor brain regions. After injections of …

The mode of activation of a barrel column: response properties of single units in the somatosensory cortex of the mouse upon whisker deflection

E Welker, M Armstrong‐James… - European Journal of …, 1993 - Wiley Online Library
Response properties of single units in the mouse barrel cortex were studied to determine the
sequence in which the neurons that form a cortical column become activated by a single …

Varying the degree of single-whisker stimulation differentially affects phases of intrinsic signals in rat barrel cortex

Dorsal raphe nucleus stimulation modulates the response of layers IV and V barrel cortical neurons in rat

V Sheibani, R Farazifard - Brain research bulletin, 2006 - Elsevier
The effect of dorsal raphe nucleus (DRN) electrical stimulation on response properties of
layers IV and V barrel cortical neurons was studied. To assess the receptive field …

Chronic suppression of activity in barrel field cortex downregulates sensory responses in contralateral barrel field cortex

L Li, V Rema, FF Ebner - Journal of neurophysiology, 2005 - journals.physiology.org
Numerous lines of evidence indicate that neural information is exchanged between the
cerebral hemispheres via the corpus callosum. Unilateral ablation lesions of barrel field …
