Two decades of single unit recording in monkeys performing short-term memory tasks has established that information can be stored as sustained neural activity. The mechanism of this information storage is unknown. The learning-based model described h

We present a neural model of the frontal eye fields. It consists of several retinotopic arrays of neuron-like units that are recurrently connected. The network is trained to make memory-guided saccades to sequentially flashed targets that appear at a

Brytes are small brains used as subunits to model the cognitive processes of larger, smarter brains. A previously developed model of scratching behaviour that uses brytes to generate the coordinated movements of two arms, one with the itch site the o

Two mechanisms are described for controlling the movement of a pair of arms. The first is an engineered motion planner that finds solutions to the ill-posed problem of making noncolliding, goal-directed movements. The second uses neural networks that

A fully recurrent neural network model was optimized to perform a spatial delayed matching-to-sample task (DMS). In DMS, a stimulus is presented at a sample location, and a match is reported when a subsequent stimulus appears at that location. Stimul

This paper presents a computational theory for generating the complicated arm movements needed for tasks such as reaching while avoiding obstacles, or scratching an itch on one arm with the other hand. The required movements are computed using many c

Studies of cortical neurons in monkeys performing short-term memory tasks have shown that information about a stimulus can be maintained by persistent neuron firing for periods of many seconds after removal of the stimulus. The mechanism by which thi

It has been widely observed that when artificial neural networks are trained by supervised learning to do computations that also occur in the nervous system, the behavior of the model neurons often closely resembles that of the real neurons involved

The generation of goal-directed movements requires the solution of many difficult computational problems. In addition to generating the forces needed for movement there are a number of essentially geometric problems. Among these are transformations f
