A model of working memory system in the form of a network of neuron-like units is considered. The units are stimulated by a periodic subthreshold stimulus and interact via inhibitory feedback. The information storage in the system occurs in the form of periodic clusters of neural activity. ...
During working memory tasks, the firing rates of single neurons recorded in behaving monkeys remain elevated without external cues. Modeling studies have explored different mechanisms that could underlie this selective persistent activity, including recurrent excitation within cell assemblies, synfire chains ...

Fly brains may be tiny in size but they’re still stuffed with very complex inter-weavings of thousands of neurons, so it’s amazing that researchers have managed to map every neuron. Two reports, first fromBBC, and second fromScientific American[££££]. At a different level, sc...
we investigated how the decoding accuracy changes with the number of neurons used to train the network. We first used the data from the last day of calcium imaging during which all five mice were performing the task at expert level and ranked the selectivity of each recorded neuron. We then...
Two-layer neural networks, comprising one node in the input layer (linear transfer function); a variable number of neurons in the hidden layer (sigmoid transfer functions), and a single neuron (linear transfer function) in the output layer were assessed for such a purpose. The (1:2:1) ...

The number of bins with significant target-dependent firing (p < 0.05, t-test) is indicated in gray scale for each neuron on the left. Neurons were sorted according to the time of absolute peak selectivity index. c Cumulative plots for the number of bins with significant target-...
