Getting the gist faster: Blurry images enhance the early temporal similarity between neural signals and convolutional neural networks

This study shows that blurry images enhance early temporal similarity between neural signals and CNNs, revealing how image perturbations affect CNN-Brain correspondence.

SpikeForest: reproducible web-facing ground-truth validation of automated neural spike sorters

SpikeForest benchmarks spike sorting algorithms using a curated database of electrophysiological recordings with ground truth, providing interactive results to guide optimal sorter selection.

Neural activity in a hippocampus-like region of the teleost pallium are associated with navigation and active sensing

The paper characterizes neural activity in a hippocampal-like region of a teleost fish brain and links active sensing to spatial navigation.

A novel time-stamp mechanism transforms egocentric encounters into an allocentric spatial representation

This paper demonstrates that electric fish use a time-stamp mechanism in the preglomerular complex to transform egocentric encounters into allocentric spatial representations through path-integration.

Real-time spike sorting platform for high-density extracellular probes with ground-truth validation and drift correction

Covariance-based features plus unsupervised density-peak clustering sort spikes from up to 1000 channels in real time on one workstation, while tolerating noise and probe drift.
