Spikes with short inter-spike intervals in frog retinal ganglion cells are more correlated with their adjacent neurons' activities.

Summary of "Spikes with short inter-spike intervals in frog retinal ganglion cells are more correlated with their adjacent neurons' activities."

Correlated firings among neurons have been extensively investigated; however, previous studies on retinal ganglion cell (RGC) population activities were mainly based on analyzing the correlated activities between the entire spike trains. In the present study, the correlation properties were explored based on burst-like activities and solitary spikes separately. The results indicate that: (1) burst-like activities were more correlated with other neurons' activities; (2) burst-like spikes correlated with their neighboring neurons represented a smaller receptive field than that of correlated solitary spikes. These results suggest that correlated burst-like spikes should be more efficient in signal transmission, and could encode more detailed spatial information.

Timing Intervals Using Population Synchrony and Spike Timing Dependent Plasticity.

We present a computational model by which ensembles of regularly spiking neurons can encode different time intervals through synchronous firing. We show that a neuron responding to a large population ...

Consensus-Based Sorting of Neuronal Spike Waveforms.

Optimizing spike-sorting algorithms is difficult because sorted clusters can rarely be checked against independently obtained "ground truth" data. In most spike-sorting algorithms in use today, the op...

The basis of sharp spike onset in standard biophysical models.

In most vertebrate neurons, spikes initiate in the axonal initial segment (AIS). When recorded in the soma, they have a surprisingly sharp onset, as if sodium (Na) channels opened abruptly. The main v...

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 efficien...

Prominent differences in sharp wave - ripples and complex spike bursts between the dorsal and the ventral rat hippocampus.

Functions of the hippocampus are segregated along its long axis and emerging evidence shows that the local circuitry is specialized accordingly. Sharp waves (SPWs) and ripples are a basic hippocampal ...
