Topic: neural decoding

Neural decoding is essential for understanding the association between neural activity and behavior. A prerequisite for most decoding methods is spike sorting, the assignment of action potentials (or spikes) to individual neurons. Current spike sorting algorithms, however, can be inaccurate and do not properly model uncertainty of spike assignments, therefore discarding information that could potentially improve decoding performance. Recent advances in high-channel-count probes like Neuropixels (NP) and extracellular analysis pipelines allow for extracting a rich set of spike features to direc

Neural decoding uses brain activity to infer internal representations of the environmental states or predict behavior. Our study aimed to decode neural signal from the Posterior Parietal Cortex (V6A), to investigate intention coding and control of assistive devices. Data were recorded during delayed reaching in three different gaze/target conditions allowing to dissociate the retinotopic and the oculomotor reference frames. We used Deep Neural Networks to learn to decode the lateral displacement and the depth of the reached target from neural data averaged over four epochs, including pre-fixat

Human vision relies on rapid eye movements (saccades) 2-3 times every second to bring peripheral targets to central foveal vision for high resolution inspection. This rapid sampling of the world defines the perception-action cycle of natural vision and profoundly impacts our perception. Marmosets have similar visual processing and eye movements as humans, including a fovea that supports high-acuity central vision. Here, I present a novel approach developed in my laboratory for investigating the neural mechanisms of visual processing using naturalistic free viewing and simple target foraging pa
