The presentation consists of a text document entitled, "Understanding How Distributions of Spike Frequencies on the Columns of a Simulated V! Network Coordinate with Distributions of Phosphenes on Regions of a Visual Geometry" and of four ppt slideshows. The text document describes how this simulation research follows up work reported in Prosthesis...

The utility of currently available cortical prosthetic vision systems is disappointing. The essential features of a neuromorphic device that is predicted to enhance vision provided by available systems follow from a hypothesis which states that the objective and subjective aspects of cortical prosthetic vision jointly constitute patterns that emerg...

Sense element engagement theory explains how neural networks produce cortical prosthetic vision. A major prediction of the theory can be tested by developing a device which is expected to enable perception of continuous forms in altered visual geometries. The research reported here completes several essential steps in developing this device: (1) re...

In response to a simulated retinal image of an object, the recurrent input to a richly connected artificial neural network organizes into a connected open set (COS) of ionic conductance values, which models the continuity and unity of a visual object. As the density of light dots on a dark background increases and then decreases, a COS appears at a...

Achieving an understanding of how qualities of experience arise in concert with the operation of neural networks could produce a revolutionary advance in neurotechnology. The work reported here explores a relationship between a visual quality and neural activity that has not previously been investigated: visual object unity may emerge from and cons...

A lattice model is developed to clarify the concept of latent or intrinsic emergent order. This is motivated by the theory of primary mental models, which proposes that conscious experience is an emergent macrostate of its neural substrate characterized by such order. Elements of the model interact to reduce an energy that depends on the relation-s...

In a previous paper, the self-trapping network (STN) was introduced as more biologically realistic than attractor neural networks (ANNs) based on the Ising model. This paper extends the previous analysis of a one-dimensional (1-D) STN storing a single memory to a model that stores multiple memories and that possesses generalized sparse connnectivit...

Attractor neural networks (ANNs) based on the Ising model are naturally fully connected and are homogeneous in structure. These features permit a deep understanding of the underlying mechanism, but limit the applicability of these models to the brain. A more biologically realistic model can be derived from an equally simple physical model by utiliz...

The self-trapping attractor neural network (STN) is a naturally sparsely-connected dynamical attractor network that models short- and long-term associative memory. Long-term storage is modeled with sparse Hebbian synapses. Unlike homogeneous dynamical models of associative memory, the STN also includes back-projections from a coupled system that co...

A means of providing the feedback necessary for an associative memory is suggested by self-trapping, the development of localization phenomena and order in coupled physical systems. Following the lead of Hopfield (1982, 1984) who exploited the formal analogy of a fully-connected ANN to an infinite ranged interaction Ising model, we have carried thr...

Reliable monitoring of the movement of small aquatic animals presents some unique problems. In the case of the larval salamander, the animal may be less than an inch long and move in sporadic short bursts. A device is described that utilizes infrared emitters and wide-band sensors inter-faced to a computer for monitoring location and movement of an...

Physiological stress is a theoretical concept, which derives its scientific meaning from its larger theoretical context—that is, from its position within a general theory of behavior. This chapter examines a conception of physiological stress derived from control theory. The general theory of behavior from which the present conception of physiologi...

The control system mode of analysis of organism-environment interactions is described and used to derive an explanation of cardiovascular reactivity. This description reveals that a negative feedback control system continuously realizes a goal or purpose over time by producing output that negates the effects of unpredictable and uncontrollable dist...

Furedy's (1989) characterization of the control system mode of analysis as a teleological form of explanation is based on a definition of purpose that is not used in my paper (Pavloski, 1989). He incorrectly describes reactivity as a controlled variable or condition, and incorrectly describes the control system error theory as not being falsifiable...

McKinney et al. (1980) reported large-magnitude reductions in heart rate (HR) from resting baseline levels, employing shaping and fading techniques and a reinforcement program in which a secondary reinforcer was awarded both contingently and immediately during training. The four male subjects in this group showed significantly greater HR decreases...

Suggests that behavioral medicine as a treatment program provides an excellent model for effective management of complex medical cases. The present authors describe a process for integrating, coordinating, and effectively applying medical and psychological principles to complex cases of work-performance deficiency in which there is some degree of m...

Reports an experiment based on the idea that a joint manipulation of both cognitive and physiological (i.e., alpha EEG) variables would provide information required for an explication of the process involved in subjective mood change. 40 Ss, mostly high school students, participated. Three main variables were considered. First, the instructions wer...

Tested the hypothesis that discrimination of a response automatically leads to control over that response. 24 Ss participated in 2 experiments, with occipital alpha EEG activity being the discriminative stimulus. Results indicate that holding the probabilities of alpha and nonalpha discrimination trials near .50 results in an absence of learning cu...

The long-term effects of therapist-delivered relaxation training alone (N=4) versus relaxation training plus frontalis EMG feedback (N=4) on self-monitoring reports of headaches and medication ingestion were assessed. Eight tension headache sufferers seeking traditional medical treatment from a neurologist served as subjects. Mean hours of pain per...

Operant conditioning of the sensorimotor rhythm of the human electroencephalogram with time-outs contingent on epileptiform activity reduces epileptic seizure rates in patients whose seizures are not well controlled by medication. A comparison of this procedure with time-out training alone demonstrates that operant conditioning of the sensorimotor...

It has been suggested by Lippold that the alpha rhythm is the result of a modulation of the corneo-retinal potential by translational eye tremor. We have attempted to replicate a critical test of the ocular origin of the alpha rhythm, altering the magnitude of the corneo-retinal potential while concomitantly measuring alpha amplitude. No changes in...

Investigated possible cognitive mediators and the role of reinforcement for noncontingent control groups in the operant conditioning of vasoconstriction. In 2 separate experiments significant differences were found between 30 experimental undergraduate Ss and 60 yoked controls, 1/2 of whom received reinforcement identical in time and number to a gi...
