Topographical and functional aspects of neuronal plasticity were studied in the primary somatosensory cortex of adult rats in acute electrophysiological experiments. Under these experimental condition...
Abstract
Fault tolerance of artificial neural networks (ANNs) has been studied mostly for passive systems, that does not react in any special way to compensate for the effect of internal failures. Sy...
A linear Hebbian equation for synaptic plasticity is derived from a more complex, nonlinear model by considering the initial development of the difference between two equivalent excitatory projections...
Slightly modified versions of an early Hebbian/anti-Hebbian neural network are shown to be capable of extracting the sparse, independent linear components of a prefiltered natural image set. An explan...
Abstract
A number of recent papers have used the approach of maximising information capacity or mutual information (MI) to examine unsupervised neural networks. In particular, for a linear `compressi...
The synapse made by hippocampal mossy fibers onto pyramidal neurons of hippocampal area CA3 displays a form of long-term potentiation (LTP) that is independent of the activation of NMDA receptors. Con...
Long-term potentiation (LTP) was investigated in the mammalian entorhinal cortex by using two in vitro preparations, the isolated brain and the entorhinal cortex slice. Hebbian and non-Hebbian types o...
Abstract
This paper describes a neural network that self-organizes to recover the original signals from sensor signals. No particular information is required about the statistical properties of the s...
