Spatial information in large-scale neural recordings

Spatial information in large-scale neural recordings

To record from a given neuron, a recording technology must be able to separate the activity of that neuron from the activity of its neighbors. Here, we develop a Fisher information based framework to determine the conditions under which this is feasible for a given technology. This framework combines measurable point spread functions with measurable noise distributions to produce theoretical bo...

Extracting spatial-temporal coherent patterns in large-scale neural recordings using dynamic mode decomposition.

BACKGROUND There is a broad need in neuroscience to understand and visualize large-scale recordings of neural activity, big data acquired by tens or hundreds of electrodes recording dynamic brain activity over minutes to hours. Such datasets are characterized by coherent patterns across both space and time, yet existing computational methods are typically restricted to analysis either in space ...

Tracking single units in chronic, large scale, neural recordings for brain machine interface applications

In the study of population coding in neurobiological systems, tracking unit identity may be critical to assess possible changes in the coding properties of neuronal constituents over prolonged periods of time. Ensuring unit stability is even more critical for reliable neural decoding of motor variables in intra-cortically controlled brain-machine interfaces (BMIs). Variability in intrinsic spik...

Large-scale Identification of Birds in Audio Recordings

The Bird Identification Task of the LifeCLEF 2014 lab is to automatically identify 501 different species in over 4000 audio recordings collected by amateur and expert ornithologists through a citizen sciences initiative. It is one of the biggest bird classification challenges so far considering the quality, quantity and variability of the recordings and the very large number of different specie...
