Unsupervised Spike Sorting for Large-Scale, High-Density Multielectrode Arrays.
We present a method for automated spike sorting for recordings with high-density, large-scale multielectrode arrays. Exploiting the dense sampling of single neurons by multiple electrodes, an efficient, low-dimensional representation of detected spikes consisting of estimated spatial spike locations and dominant spike shape features is exploited for fast and reliable clustering into single unit...
متن کاملExplorer Unsupervised spike sorting for large scale , high density multielectrode arrays
A new method for automated spike sorting for recordings with high density, large scale multielectrode arrays is presented. It is based on an e cient, low-dimensional representation of detected events by their estimated spatial current source locations and dominant spike shape features. Millions of events can be sorted in just minutes, and the full analysis chain scales roughly linearly with rec...
متن کاملAutomatic Spike Sorting Using Tuning Information
Current spike sorting methods focus on clustering neurons' characteristic spike waveforms. The resulting spike-sorted data are typically used to estimate how covariates of interest modulate the firing rates of neurons. However, when these covariates do modulate the firing rates, they provide information about spikes' identities, which thus far have been ignored for the purpose of spike sorting....
متن کاملElectrical modeling of the cell-electrode interface for recording neural activity from high-density microelectrode arrays
Accurate electrical models are needed to support the design of modern microelectrode arrays. The point-contact model is presented thoroughly, and an area-contact model is analytically derived in order to model the electrical characteristics of the cell–electrode interface at subcellular resolution. An optimum electrode diameter for recording the electrical activity of neurons is analytically de...
متن کاملMicroelectrode Arrays
The development of implantable devices which enable fully wireless transmission of brain signals, recorded by microelectrode arrays (MEA) as dynamical neural circuit information, is one important goal for advancing human neuroprostheses. Current brain sensing research for prostheses via first clinical trials is offering tantalizing glimpses for the future, even if these technologies are cumbers...
