Spontaneous Local Gamma Oscillation Selectively Enhances Neural Network Responsiveness
2009
PLoS Computational Biology
Preserved Fulltext
This spontaneous oscillatory network activity injects a periodic local current that could amplify a weak synaptic input and enhance the network's responsiveness. ...
This suggests a generalized mechanism by which neural oscillatory activity can enhance the selectivity of a neural network to FF inputs. ...
Spontaneous cortical oscillations can be locally induced by spatially localized thalamic inputs, and the cortical response character can also be selectively tuned within a limited region. ...
