Facilitating sensory responses in developing mouse somatosensory barrel cortex

The sensory responses in the barrel cortex of mice aged postnatal day (P)7-P12 evoked by a single whisker deflection are smaller in amplitude and spread over a smaller area than those measured in P13-P21 mice. However, repetitive 10-Hz stimulation or paire ...

Transcranial Magnetic Stimulation of Early Visual Cortex Reveals a Window of Integration of Substantial Duration.

Michael Herzog, Frank Scharnowski, Johannes Rüter

How the brain achieves integration of temporally dispersed information is one of the enigmas in the neurosciences. By combining feature fusion with transcranial magnetic stimulation (TMS), we show that individual visual features are independently stored fo ...

Predicting neuronal activity with simple models of the threshold type: Adaptive Exponential Integrate-and-Fire model with two compartments

Wulfram Gerstner, Renaud Jolivet, Claudia Clopath

An adaptive Exponential Integrate-and-Fire (aEIF) model was used to predict the activity of layer-V-pyramidal neurons of rat neocortex under random current injection. A new protocol has been developed to extract the parameters of the aEIF model using an op ...

Disynaptic inhibition between neocortical pyramidal cells mediated by Martinotti cells

Henry Markram, Gilad Silberberg

Reliable activation of inhibitory pathways is essential for maintaining the balance between excitation and inhibition during cortical activity. Little is known, however, about the activation of these pathways at the level of the local neocortical microcirc ...

Dynamics of lactate concentration and blood oxygen level-dependent effect in the human visual cortex during repeated identical stimuli

Rolf Gruetter

In vivo 1H NMR spectroscopy at 7 T was utilized to measure the changes in lactate concentration upon repeated identical visual stimuli, each lasting for 2 min. The average amplitude of these increases was found to be reduced over time (P < 0.01), from 0.13 ...

The influence of hands posture on mental rotation of hands and feet

Silvio Ionta

Behavioural and functional neuroanatomy studies demonstrate that mental rotation of body parts is carried out through a sort of inner motor simulation. Here we examined whether changes of hands posture influence the mental rotation of hands and feet. Twent ...

Altered neocortical microcircuitry in the valproic acid rat model of autism

Tania Rinaldi

Autism is a wide-spectrum disorder with early childhood onset, affecting general cognitive capabilities and, in particular, complex information processing. Although interesting directions of research start to appear, the precise causes of the disorder and ...

Spontaneous and evoked synaptic rewiring in the neonatal neocortex

Henry Markram, Jean-Vincent Le Bé

The local microcircuitry of the neocortex is structurally a tabula rasa, with the axon of each pyramidal neuron having numerous submicrometer appositions with the dendrites of all neighboring pyramidal neurons, but is functionally highly selective, with sy ...

Visualizing the cortical representation of whisker touch: voltage-sensitive dye imaging in freely moving mice

Carl Petersen

Voltage-sensitive dye imaging resolves the spatiotemporal dynamics of supragranular subthreshold cortical activity with millisecond temporal resolution and subcolumnar spatial resolution. We used a flexible fiber optic image bundle to visualize voltage-sen ...

Visuo-motor pathways in humans revealed by event-related fMRI

Jean-Philippe Thiran, Reto Meuli, Clotaire Michel

Whether different brain networks are involved in generating unimanual responses to a simple visual stimulus presented in the ipsilateral versus contralateral hemifield remains a controversial issue. Visuo-motor routing was investigated with event-related f ...
