Invariance of visual operations at the level of receptive fields. [PDF]

PLoS ONE, 2013
The brain is able to maintain a stable perception although the visual stimuli vary substantially on the retina due to geometric transformations and lighting variations in the environment.

Receptive Field Space for Point Cloud Analysis [PDF]

Sensors
Similar to convolutional neural networks for image processing, existing analysis methods for 3D point clouds often require the designation of a local neighborhood to describe the local features of the point cloud.

Spatial frequency adaptation modulates population receptive field sizes [PDF]

eLife
The spatial tuning of neuronal populations in the early visual cortical regions is related to the spatial frequency (SF) selectivity of neurons. However, there has been no direct investigation into how this relationship is reflected in population ...

Receptive field inference with localized priors. [PDF]

PLoS Computational Biology, 2011
The linear receptive field describes a mapping from sensory stimuli to a one-dimensional variable governing a neuron's spike response. However, traditional receptive field estimators such as the spike-triggered average converge slowly and often require ...

Bayesian population receptive field modelling [PDF]

NeuroImage, 2016
We introduce a probabilistic (Bayesian) framework and associated software toolbox for mapping population receptive fields (pRFs) based on fMRI data. This generic approach is intended to work with stimuli of any dimension and is demonstrated and validated

qPRF: A system to accelerate population receptive field modeling [PDF]

NeuroImage
BOLD response can be fitted using the population receptive field (PRF) model to reveal how visual input is represented on the cortex (Dumoulin and Wandell, 2008). Fitting the PRF model costs considerable time, often requiring days to analyze BOLD signals

Multi-Branch Cascade Receptive Field Residual Network

IEEE Access, 2023
Deep convolutional neural networks (CNNs) have significantly enhanced image classification in the past decade. This paper proposes Multi-branch Cascade Receptive Field Residual Networks (MCRF-ResNets) based on the original Residual Network (ResNet ...

Visual Deprivation Retards the Maturation of Dendritic Fields and Receptive Fields of Mouse Retinal Ganglion Cells

Frontiers in Cellular Neuroscience, 2021
It was well documented that both the size of the dendritic field and receptive field of retinal ganglion cells (RGCs) are developmentally regulated in the mammalian retina, and visual stimulation is required for the maturation of the dendritic and ...

A Mixed Visual Encoding Model Based on the Larger-Scale Receptive Field for Human Brain Activity

Brain Sciences, 2022
Research on visual encoding models for functional magnetic resonance imaging derived from deep neural networks, especially CNN (e.g., VGG16), has been developed.
