Local field potentials (LFPs) sampled with extracellular electrodes are frequently used as a measure of population neuronal activity. However, relating such measurements to underlying neuronal behaviour and connectivity is non-trivial. To help study this link, we developed the Virtual Electrode Recording Tool for EXtracellular potentials (VERTEX). We first(More)

While the physics of local field potential (LFP) generation are well-established, the complexity of neural network dynamics means that interpreting LFP measurements in terms of the underlying neural activity is very difficult [1]. Recent studies have therefore investigated forward models of the LFP: calculating the LFP due to known arrangements of neuronal(More)
Local field potentials (LFPs), measured using extracellu-lar electrodes, provide information about local neuronal population activity. The development of multi-electrode arrays (MEAs) that measure LFPs simultaneously at different network locations has led to a renewed interest in the LFP as a measure of neuronal network activity [1]. While there is a(More)
Motivation: Real cortical tissue curves and folds according to experiment data. However, the cortical slice model is organized in flat layers currently. This project would extend the cortical slice model in order to be able to specify arbitrary curvatures to the cortical layers and investigate the effect of curvature and folding on neuron density and layer(More)
