Disorder and the Neural Representation of Complex Odors

open access: yesFrontiers in Computational Neuroscience, 2022
Animals smelling in the real world use a small number of receptors to sense a vast number of natural molecular mixtures, and proceed to learn arbitrary associations between odors and valences.

Efficient Coding of the Embedded Signal in Steganographic Systems with Multiple Access [PDF]

open access: yesProblems of the Regional Energetics, 2021
Today, steganographic systems with multiple access are of considerable importance. In such sys-tems, the orthogonal Walsh-Hadamard transform is most often used for multiplexing and divid-ing channels, which leads to the need for efficient coding of the ...

T-type Calcium Channels Cause Bursts of Spikes in Motor but not Sensory Thalamic Neurons during Mimicry of Natural Patterns of Synaptic Input

open access: yesFrontiers in Cellular Neuroscience, 2015
Although neurons within intact nervous systems can be classified as ‘sensory’ or ‘motor,’ it is not known whether there is any general distinction between sensory and motor neurons at the cellular or molecular levels.

On the Role of LGN/V1 Spontaneous Activity as an Innate Learning Pattern for Visual Development

open access: yesFrontiers in Physiology, 2021
Correlated, spontaneous neural activity is known to play a necessary role in visual development, but the higher-order statistical structure of these coherent, amorphous patterns has only begun to emerge in the past decade.

Adaptive coding for dynamic sensory inference

open access: yeseLife, 2018
Behavior relies on the ability of sensory systems to infer properties of the environment from incoming stimuli. The accuracy of inference depends on the fidelity with which behaviorally relevant properties of stimuli are encoded in neural responses. High-

ROI coding of volumetric medical images with application to visualisation [PDF]

open access: yes, 2003
This paper presents region of interest (ROI) coding of volumetric medical images with the region itself being three dimensional. An extension to 3D-SPIHT which allows 3D ROI coding is proposed.

Looking for Image Statistics: Active Vision With Avatars in a Naturalistic Virtual Environment

open access: yesFrontiers in Psychology, 2021
The efficient coding hypothesis posits that sensory systems are tuned to the regularities of their natural input. The statistics of natural image databases have been the topic of many studies, which have revealed biases in the distribution of ...

Hamming codes are rate-efficient array codes [PDF]

open access: yesGLOBECOM '05. IEEE Global Telecommunications Conference, 2005., 2005
Array codes are error-correcting codes of very low complexity that were initially used for burst and erasure correction in redundant arrays of inexpensive disks (RAID) architectures and other storage applications. The structure of these codes allows a very simple encoding and decoding mechanism.

An efficient chain code with Huffman coding

open access: yesPattern Recognition, 2005
This paper presents a new chain code based on the eight-direction Freeman code. Each element in the chain is coded as a relative angle difference between it and the previous element. Statistical analysis showed that the probabilities of the Freeman codes differ importantly. Therefore, the Huffman coding was applied.

A mechanistic account of visual discomfort

open access: yesFrontiers in Neuroscience, 2023
Much of the neural machinery of the early visual cortex, from the extraction of local orientations to contextual modulations through lateral interactions, is thought to have developed to provide a sparse encoding of contour in natural scenes, allowing ...
