Fixational eye movements induce aperiodic motion of the retinal image. However, it is not yet fully understood how fixational eye movements affect retinal information processing.

Cortical sensory neurons are commonly characterized using the receptive field, the linear dependence of their response on the stimulus. In primary auditory cortex neurons can be characterized by their spectrotemporal receptive fields, the spectral and ...

Adaptation-dependent synchronous activity contributes to receptive field size change of bullfrog retinal ganglion cell. [PDF]
Nearby retinal ganglion cells of similar functional subtype have a tendency to discharge spikes in synchrony. The synchronized activity is involved in encoding some aspects of visual input.

Transformable Dilated Convolution by Distance for LiDAR Semantic Segmentation
LiDAR semantic segmentation is essential in autonomous vehicle safety. A rotating 3D LiDAR projects more laser points onto nearby objects and fewer points onto farther objects.

Mapping sequences can bias population receptive field estimates
Population receptive field (pRF) modelling is a common technique for estimating the stimulus-selectivity of populations of neurons using neuroimaging. Here, we aimed to address if pRF properties estimated with this method depend on the spatio-temporal ...

Nonlinear Hebbian learning as a unifying principle in receptive field formation [PDF]
The development of sensory receptive fields has been modeled in the past by a variety of models including normative models such as sparse coding or independent component analysis and bottom-up models such as spike-timing dependent plasticity or the ...

Does Corticothalamic Feedback Control Cortical Velocity Tuning? [PDF]
The thalamus is the major gate to the cortex and its contribution to cortical receptive field properties is well established. Cortical feedback to the thalamus is, in turn, the anatomically dominant input to relay cells, yet its influence on thalamic ...

Mechanisms underlying the emergence and plasticity of representational discontinuities in the mammalian primary somatosensory cortical representation of the hand are investigated in a computational model. The model consists of an input lattice organized

Stereo Matching Algorithm Based on Atrous Convolution and Attention Module [PDF]
Most of the stereo matching algorithms based on convolutional neural networks require a large receptive field. However, the number of parameters in most algorithms is easy to increase when the receptive field is enlarged, which leads to high requirements
