Temporal processing in sensory systems

Current Opinion in Neurobiology, 2000
The idea that sensory information is represented by the temporal firing patterns of neurons or entire networks, rather than by firing rates measured over long integration times, has recently gained increasing experimental support. A number of mechanisms that help to preserve temporal information in ascending sensory systems have been identified, and ...

Neuropeptides in sensory signal processing

Cell and Tissue Research, 2018
Peptides released from trigeminal fibers fulfill well-understood functions in neuroinflammatory processes and in the modulation of nociceptive signal processing. In particular, calcitonin gene-related peptide (CGRP) and substance P (SP), released from afferent nerve terminals, exert paracrine effects on the surrounding tissue and this has been recently

Cognitive Architectures for Sensory Processing

Proceedings of the IEEE, 2014
This paper describes our efforts to design a cognitive architecture for object recognition in video. Unlike most efforts in computer vision, our work proposes a Bayesian approach to object recognition in video, using a hierarchical, distributed architecture of dynamic processing elements that learns in a self-organizing way to cluster objects in the ...

Sensory processing in Huntington’s disease

Clinical Neurophysiology, 2017
An intriguing electrophysiological feature of patients with Huntington's disease (HD) is the delayed latency and decreased amplitude of somatosensory long-latency evoked potentials (LLeps). We investigated whether such dysfunction was associated with delayed conscious perception of the sensory stimulus.Sixteen HD patients and 16 control subjects faced ...

A point process analysis of sensory encoding

First International IEEE EMBS Conference on Neural Engineering, 2003. Conference Proceedings., 2003
Nowhere is the sparse nature of neuronal coding more evident than in the sensory cortex, where neuronal response becomes increasingly tuned to specific features of the sensory environment. For such situations, where rate modulation schemes do not accurately describe the neuronal response to sensory stimuli, statistical descriptions based on point ...

Imperceptible Stimuli and Sensory Processing Impediment

Science, 2003
Weak sensory stimuli can fully escape conscious perception and yet evoke minute electroencephalography (EEG) responses ([1][1]), indicating at least partial cortical processing of such “subliminal” input.

CENTRAL DOPAMINE NEURONS AND SENSORY PROCESSING

Journal of Psychiatric Research, 1974
Publisher Summary This chapter discusses central dopamine (DA) neuronsand sensory processing. The function of central DA neurons is associated with schizophrenia: Amphetamine psychosis is thought to resemble schizophrenia, while treatment with neuroleptic drugs are used against the disease.

Sensory discrimination: decision process

Journal of Neurophysiology, 1980
1. This paper and a following paper deal with problems, such as the following, that arise in experimental studies of the neural mechanisms underlying sensory discrimination: What measures of neural activity are relevant in such a study? How can sample data from the responses of single neurons be combined to represent the information relayed by a ...
