A radial map of multi-whisker correlation selectivity in the rat barrel cortex

Luc Estebanez, Julien Bertherat, Daniel E. Shulz, Laurent Bourdieu, Jean- François Léger
2016 Nature Communications  
The barrel cortex also encodes spatio-temporal correlation patterns of multi-whisker inputs, but so far the cortical mapping of neurons tuned to such input statistics is unknown.  ...  In the barrel cortex, several features of single-whisker stimuli are organized in functional maps.  ...  We are grateful to Valerie Ego-Stengel for her careful reading of the manuscript.  ...

Is optical imaging spectroscopy a viable measurement technique for the investigation of the negative BOLD phenomenon? A concurrent optical imaging spectroscopy and fMRI study at high field (7T)

Aneurin J. Kennerley, John E. Mayhew, Luke Boorman, Ying Zheng, Jason Berwick
2012 NeuroImage  
These experiments suggested that the negative BOLD signal in response to whisker stimulation was a result of an increase in deoxyhaemoglobin and reduced multi-unit activity in the deep cortical layers.  ...  We used concurrent fMRI with 2D-OIS techniques for the investigation of the haemodynamics underlying the negative BOLD at 7 Tesla.  ...  We thank the technical staff of the lab (Marion Simkins & Natalie Kennerley) for their assistance.  ...

Synthesis of a comprehensive population code for contextual features in the awake sensory cortex

Evan H Lyall, Daniel P Mossing, Scott R Pluta, Yun Wen Chu, Amir Dudai, Hillel Adesnik
2021 eLife  
This may explain how the brain exploits the thalamocortical expansion of dimensionality to encode arbitrary complex features of sensory stimuli.  ...  How cortical circuits build representations of complex objects is poorly understood.  ...  Additionally, whiskers are of variable length and physical properties (Yang et al., 2019) which could also lead to non-intuitive spatio-temporal sequences of whisker-object contacts.  ...

Neurotransmitter Release at the Thalamocortical Synapse Instructs Barrel Formation But Not Axon Patterning in the Somatosensory Cortex

N. Narboux-Neme, A. Evrard, I. Ferezou, R. S. Erzurumlu, P. S. Kaeser, J. Laine, J. Rossier, N. Ropert, T. C. Sudhof, P. Gaspar
2012 Journal of Neuroscience  
A barrelless phenotype was found with a dissociation of effects on the presynaptic and postsynaptic cellular elements of the barrel.  ...  Thus, efficient synaptic release is required at thalamocortical but not at corticocortical synapses for building the whisker to barrel map and for efficient sensory function.  ...  However, the spatio-temporal patterning of the somatosensory-evoked responses was undisturbed.  ...
