Firing rate models for gamma oscillations in I-I and E-I networks
Firing rate models for describing the mean-field activities of neuronal ensembles can be used effectively to study network function and dynamics, including synchronization and rhythmicity of excitatory-inhibitory populations. However, traditional ...
A cortical field theory – dynamics and symmetries
We characterise cortical dynamics using partial differential equations (PDEs), analysing various connectivity patterns within the cortical sheet. This exploration yields diverse dynamics, encompassing wave equations and limit cycle activity. We ...
A computational model of auditory chirp-velocity sensitivity and amplitude-modulation tuning in inferior colliculus neurons
We demonstrate a model of chirp-velocity sensitivity in the inferior colliculus (IC) that retains the tuning to amplitude modulation (AM) that was established in earlier models. The mechanism of velocity sensitivity is sequence detection by ...
Formation and retrieval of cell assemblies in a biologically realistic spiking neural network model of area CA3 in the mouse hippocampus
The hippocampal formation is critical for episodic memory, with area Cornu Ammonis 3 (CA3) a necessary substrate for auto-associative pattern completion. Recent theoretical and experimental evidence suggests that the formation and retrieval of ...
Computational model of layer 2/3 in mouse primary visual cortex explains observed visuomotor mismatch response
Activity in layer 2/3 of the mouse primary visual cortex has been shown to depend both on visual input and the mouse’s locomotion. Moreover, this activity is altered by a mismatch between the observed visual flow and the predicted visual flow from ...
