We developed a neural field model, tuned near an oscillatory instability, in which the WM-like input can modulate the frequency and amplitude of the oscillation. Our neural field model has a spatial-like domain in which an input that preferentially targets a point-a stimulus feature-on the domain will induce feature-specific activity changes. These feature-specific activity changes affect both the mean rate of spikes and the relative timing of spiking activity to the global field oscillation-the phase of the spiking activity. From these two dynamical signatures, we define both a spike rate code and an oscillatory phase code. We assess the performance of these two codes to discriminate stimulus features using an information-theoretic analysis. We show that global WM input modulations can enhance phase code discrimination while simultaneously reducing rate code discrimination. Moreover, we find that the phase code performance is roughly two orders of magnitude larger than that of the rate code defined for the same model solutions. The results of our model have applications to sensory areas of the brain, to which prefrontal areas send inputs reflecting the content of WM. These WM inputs to sensory areas have been established to induce oscillatory changes similar to our model. Our model results suggest a mechanism by which WM signals may enhance sensory information represented in oscillatory activity beyond the comparatively weak representations based on the mean rate activity.}, keywords = {PHASE; INFORMATION THEORY; working memory; computational model; neural coding}, year = {2024}, eissn = {1662-5188} } @article{MTMT:34819514, title = {Excitatory/inhibitory balance emerges as a key factor for RBN performance, overriding attractor dynamics}, url = {https://m2.mtmt.hu/api/publication/34819514}, author = {Calvet, E. and Rouat, J. and Reulet, B.}, doi = {10.3389/fncom.2023.1223258}, journal-iso = {FRONT COMPUT NEUROSC}, journal = {FRONTIERS IN COMPUTATIONAL NEUROSCIENCE}, volume = {17}, unique-id = {34819514}, issn = {1662-5188}, year = {2023}, eissn = {1662-5188} } @article{MTMT:34714439, title = {Spatial frequency channels depend on stimulus bandwidth in normal and amblyopic vision: an exploratory factor analysis}, url = {https://m2.mtmt.hu/api/publication/34714439}, author = {Reynaud, A. and Min, S.H.}, doi = {10.3389/fncom.2023.1241455}, journal-iso = {FRONT COMPUT NEUROSC}, journal = {FRONTIERS IN COMPUTATIONAL NEUROSCIENCE}, volume = {17}, unique-id = {34714439}, issn = {1662-5188}, abstract = {The Contrast Sensitivity Function (CSF) is the measure of an observer’s contrast sensitivity as a function of spatial frequency. It is a sensitive measure to assess visual function in fundamental and clinical settings. Human contrast sensitivity is subserved by different spatial frequency channels. Also, it is known that amblyopes have deficits in contrast sensitivity, particularly at high spatial frequencies. Therefore, the aim of this study was to assess whether the contrast sensitivity function is subtended by the same spatial frequency channels in control and amblyopic populations. To determine these spatial frequency channels, we performed an exploratory factor analysis on five datasets of contrasts sensitivity functions of amblyopic and control participants measured using either gratings or noise patches, taken from our previous studies. In the range of 0.25–10 c/d, we identified two spatial frequency channels. When the CSF was measured with noise patches, the spatial frequency channels presented very similar tuning in the amblyopic eye and the fellow eye and were also similar to what was observed in controls. The only major difference was that the weight attributed to the high frequency channel was reduced by approximately 50% in the amblyopic eye. However, when the CSF was measured using gratings, the spatial frequency channels of the amblyopic eye were tuned toward lower spatial frequencies. These findings suggest that there is no mechanistic deficit for contrast sensitivity in amblyopia and that amblyopic vision may just be subjected to excessive internal noise and attenuation at higher spatial frequencies, thereby supporting the use of therapeutic strategies that involve rebalancing contrast.
