Thalamocortical Loops and Information Processing
A pathophysiological chain reaction at the origin of neurogenic pain. It consists of: 1) a reduction of excitatory inputs onto thalamic cells, which results in cell membrane hyperpolarization, 2) the production of low-threshold calcium spike bursts by deinactivation of calcium T-channels, discharging at low (theta) frequency, 3) a progressive increase of the number of thalamocortical modules di...
متن کاملProcessing of Analogy in the Thalamocortical Circuit
The corticothalamic feedback and the thalamic reticular nucleus have gained much attention lately because of their integrative and modulatory functions. A previous study by the author suggested that this circuitry can process analogies (i.e., the analogy hypothesis). In this paper, the proposed model was implemented as a network of leaky integrate-and-fire neurons to test the analogy hypothesis...
متن کاملNonlinear processing of tactile information in the thalamocortical loop.
Rats explore tangible objects in a manner such that, at any given moment in time, multiple facial whiskers simultaneously contact the surface of the object. Although both thalamic and cortical neurons responsible for processing such tactile information have large, multiwhisker receptive fields, it remains unclear what kinds of computations can be carried out by these neuronal populations when b...
متن کاملRole of inhibitory feedback for information processing in thalamocortical circuits.
The information transfer in the thalamus is blocked dynamically during sleep, in conjunction with the occurrence of spindle waves. In order to describe the dynamic mechanisms which control the sensory transfer of information, it is necessary to have a qualitative model for the response properties of thalamic neurons. As the theoretical understanding of the mechanism remains incomplete, we analy...
متن کاملA framework for investigating thalamocortical activity in multistage information processing.
A framework for investigating information processing in cortico-thalamocortical (cortico-TC) networks is presented, that in part can be used to model and interpret individual changes in electroencephalographic spectra and event-related potentials such as those from the Brain Resource International Database. Scientific work covering neurophysiology, TC firing modes, and TC models are explored in...
