Motor cortex broadly engages excitatory and inhibitory neurons in somatosensory barrel cortex.
Anatomical studies have shown that primary somatosensory (S1) and primary motor (M1) cortices are reciprocally connected. The M1 to S1 projection is thought to represent a modulatory signal that conveys motor-related information to S1. Here, we investigated M1 synaptic inputs to S1 by injecting an AAV virus containing channelrhodopsin-2 and a fluorescent tag into M1. Consistent with previous re...
متن کاملAxonal Dynamics of Excitatory and Inhibitory Neurons in Somatosensory Cortex
Cortical topography can be remapped as a consequence of sensory deprivation, suggesting that cortical circuits are continually modified by experience. To see the effect of altered sensory experience on specific components of cortical circuits, we imaged neurons, labeled with a genetically modified adeno-associated virus, in the intact mouse somatosensory cortex before and after whisker plucking...
متن کاملSomatosensory Response Properties of Excitatory and Inhibitory Neurons in Rat 1 Motor Cortex
17 18 In sensory cortical networks, peripheral inputs differentially activate excitatory and inhibitory 19 neurons. Inhibitory neurons typically have larger responses and broader receptive field tuning 20 compared to excitatory neurons. These differences are thought to underlie the powerful 21 feed-forward inhibition that occurs in response to sensory input. In the motor cortex, as in the 22 so...

متن کاملEffect of phasic electrical locus coeruleus stimulation on inhibitory and excitatory receptive fields of layer V barrel cortex neurons in male rat
Introduction: It is believed that Locus Coeruleus (LC) influences the sensory information processing. However, its role in cortical surround inhibitory mechanism is not understood. In this experiment, using controlled mechanical displacement of whiskers we investigated the effect of phasic electrical stimulation of LC on response of layer V barrel cortical neurons in anesthetized rat. Methods: ...
