Barrages of synaptic activity control the gain and sensitivity of cortical neurons.
Ongoing synaptic activity, ever present in cortical neurons, may vary widely in its amplitude and characteristics, potentially having a strong influence on neuronal processing. Intracellular recordings in layer 5 pyramidal cells in prefrontal and visual cortical slices maintained in vitro revealed spontaneous periods of synaptic bombardment. Testing the responsiveness of these cortical cells to...
متن کاملIntegration of Subthreshold and Suprathreshold Excitatory Barrages along the Somatodendritic Axis of Pyramidal Neurons
Neurons integrate inputs arriving in different cellular compartments to produce action potentials that are transmitted to other neurons. Because of the voltage- and time-dependent conductances in the dendrites and soma, summation of synaptic inputs is complex. To examine summation of membrane potentials and firing rates, we performed whole-cell recordings from layer 5 cortical pyramidal neurons...
متن کاملSpike-timing control by dendritic plateau potentials in the presence of synaptic barrages
Apical and tuft dendrites of pyramidal neurons support regenerative electrical potentials, giving rise to long-lasting (approximately hundreds of milliseconds) and strong (~50 mV from rest) depolarizations. Such plateau events rely on clustered glutamatergic input, can be mediated by calcium or by NMDA currents, and often generate somatic depolarizations that last for the time course of the den...
متن کاملProbabilistic Method for Seismic Vulnerability Ranking of Canadian Hydropower Dams
A probabilistic method was developed for ranking Canadian hydropower dams according to their seismic vulnerability. The method is based on the probabilistic seismic hazard at the dam location, the seismic fragility of the dam, and the construction date of the dam. The seismic hazard is represented by the peak ground acceleration of seismic motions at the dam location for a specified probability...
متن کاملNeurobiology of Disease Modular Propagation of Epileptiform Activity: Evidence for an Inhibitory Veto in Neocortex
What regulates the spread of activity through cortical circuits? We present here data indicating a pivotal role for a vetoing inhibition restraining modules of pyramidal neurons. We combined fast calcium imaging of network activity with whole-cell recordings to examine epileptiform propagation in mouse neocortical slices. Epileptiform activity was induced by washing Mg 2 ions out of the slice. ...
