Notes on Sensory Binding and Coherence
... coherence may act like coupled oscillators in a feedback circuit, or they may take the form of parallel circuits engaged in synchronized processing tasks....
... 1) modular coherence; 2) linear stability; 3) feedback control; 4) adaptability; and 5) self-awareness. When all of these functions and operating properties are working in tandem you get something resembling human consciousness.2 When one or more...
Chaotic fingerprints and space-time labyrinths
Video feedback is a great example of real-time evolving self-organising systems near the edge of chaos. With a relatively simple camera-monitor/TV set-up you can produce a vast spectrum of time-based fractal species, many of which bare great similari...
Recurrent Excitation in Neocortical Circuits
... do not reflect the anatomy and physiology of feedback excitation and are restricted to serial feedforward excitation. This report describes how populations of neurons in cat visual cortex can use excitatory feedback, characterized as an effectiv...
We consider traveling front and pulse solutions to a system of integro-differential equations used to describe the activity of synaptically coupled neuronal networks in a single spatial dimension. Our first goal is to establish a series of direct lin...
Presynaptic regulation of recurrent excitation by D1 receptors in prefrontal circuits
The prefrontal cortex plays a fundamental role in the working memory functions of the cerebral cortex and is also the site of dysfunction in several neurological and psychiatric disorders, including schizophrenia. Prefrontal neurons are distinguished...
Orientation selectivity in visual cortex by fluctuation-controlled criticality
[fig]1;1[/fig]Within a large-scale neuronal network model of macaque primary visual cortex, we examined how intrinsic dynamic fluctuations in synaptic currents modify the effect of strong recurrent excitation on orientation selectivity. Previously...
Trajectory selection in multistable systems using periodic drivings
It is common for a periodically driven nonlinear system to have coexistent attractors. Specifically, we are interested in the case where one of these attractors is a limit cycle whose period is an integer multiple of that of the driving. Suppose tha...
Video feedback is the process of pointing a camera at the screen displaying the camera's output. This creates a feedback loop of images infinitely repeating onto and over themselves creating interesting patterns. An initial curious result has become ...
The Control Interrupt Model of Psychedelic Action
... to control the flow of bottom-up sensory input. feedback modulation of incoming signal is an example of self-stabilizing control in a signal processing system. Using the tenets of cognition and control theory it is possible to describe a model in w...
