Computational Algorithms Derived from Multiple Scales of Neocortical Processing

Neocortical Dynamics at Multiple Scales : EEG Standing

The dynamic behavior of scalp potentials (EEG) is apparently due to some combination of global and local processes with important top-down and bottom-up interactions across spatial scales. In treating global mechanisms, we stress the importance of myelinated axon propagation delays and periodic boundary conditions in the cortical-white matter system, which is topologically close to a spherical ...

Novel speech processing mechanism derived from auditory neocortical circuit analysis

Analysis of the prominent anatomical and physiological features of auditory thalamus and neocortex has enabled construction of models designed to identify functionality emergent from these biological circuits. These models have recently been shown to provide powerful computational mechanisms for processing of continuous time-varying sequences such as speech; testing on speech databases has yiel...

Statistical mechanics of neocortical interactions: multiple scales of EEG.

A plausible model of the statistical mechanics of neocortical interactions (SMNI), spans several important neuroscientific phenomena including phenomena measured by electroencephalography (EEG) (Ingber, 1982; Ingber, 1983; Ingber, 1984; Ingber, 1985a; Ingber, 1985b; Ingber, 1991; Ingber, 1992; Ingber, 1994; Ingber, 1995a; Ingber and Nunez, 1990). Fitted SMNI functional forms to EEG data may hel...

Short Communication: Synergy among multiple scales of neocortical interactions

A lot of what we consider Consciousness (C) is conscious attention to short-term memories (STM). At least some STM memories are actively processed by highly synchronized patterns of neuronal firings, with enough synchrony to be able to be easily measured by scalp electroencephalographic recordings (EEG). Large-scale synchronous macrocolumnar EEG firings is a top-down process developed by a stat...
