Network Receptive Field Modeling Reveals Extensive Integration and Multi-feature Selectivity in Auditory Cortical Neurons.

open access: yesPLoS Computational Biology, 2016
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 ...

Information Optimization in Coupled Audio-Visual Cortical Maps [PDF]

open access: yes, 2002
Barn owls hunt in the dark by using cues from both sight and sound to locate their prey. This task is facilitated by topographic maps of the external space formed by neurons (e.g., in the optic tectum) that respond to visual or aural signals from a ...

The receptive field is dead. Long live the receptive field? [PDF]

open access: yesCurrent Opinion in Neurobiology, 2014
Advances in experimental techniques, including behavioral paradigms using rich stimuli under closed loop conditions and the interfacing of neural systems with external inputs and outputs, reveal complex dynamics in the neural code and require a revisiting of standard concepts of representation.

Dilated Deep Residual Network for Image Denoising [PDF]

open access: yes, 2017
Variations of deep neural networks such as convolutional neural network (CNN) have been successfully applied to image denoising. The goal is to automatically learn a mapping from a noisy image to a clean image given training data consisting of pairs of ...

The Observable Field for Antennas in Reception

open access: yesIEEE Transactions on Antennas and Propagation, 2018
In this paper, the portion of the incident field that can be received by an antenna is investigated: the observable field. This field can be estimated relying only on the volume allocated to the antenna and thus independently of the specific antenna geometry.

Global Jitter Motion of the Retinal Image Dynamically Alters the Receptive Field Properties of Retinal Ganglion Cells

open access: yesFrontiers in Neuroscience, 2019
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.

Developmental sensory experience balances cortical excitation and inhibition. [PDF]

open access: yes, 2010
Early in life, neural circuits are highly susceptible to outside influences. The organization of the primary auditory cortex (A1) in particular is governed by acoustic experience during the critical period, an epoch near the beginning of postnatal ...

Characterizing Auditory Receptive Fields [PDF]

open access: yesNeuron, 2008
In this issue of Neuron, two papers by Atencio et al. and Nagel and Doupe adapt new computational methods to map the spectrotemporal response fields of neurons in the auditory cortex. The papers take different but complementary approaches to apply theoretical techniques to classical methods of receptive field mapping and, in doing so, provide exciting ...

Sparse coding can predict primary visual cortex receptive field changes induced by abnormal visual input.

open access: yesPLoS Computational Biology, 2013
Receptive fields acquired through unsupervised learning of sparse representations of natural scenes have similar properties to primary visual cortex (V1) simple cell receptive fields.

Emergent spatial patterns of excitatory and inhibitory synaptic strengths drive somatotopic representational discontinuities and their plasticity in a computational model of primary sensory cortical area 3b

open access: yesFrontiers in Computational Neuroscience, 2016
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
