delves deeply into the contemporary neuroscience of brain plasticity. Doidge is a psychiatrist and psychoanalyst and works as a researcher at the Columbia University Center for Psychoanalytic Training and Research in New York and as a faculty member in the University of Toronto's Department of Psychiatry. His artistry with words reflects the fact that he is(More)
Numerous studies have suggested that the brain may encode information in the temporal firing pattern of neurons. However, little is known regarding how information may come to be temporally encoded and about the potential computational advantages of temporal coding. Here, it is shown that local inhibition may underlie the temporal encoding of spatial(More)
The brain represents the skin surface as a topographic map in the somatosensory cortex. This map has been shown experimentally to be modifiable in a use-dependent fashion throughout life. We present a neural network simulation of the competitive dynamics underlying this cortical plasticity by detailed analysis of receptive field properties of model neurons(More)
One of the current challenges to understanding neural information processing in biological systems is to decipher the \code" carried by large populations of neurons acting in parallel. We present an algorithm for automated discovery of stochastic ring patterns in large ensembles of neurons. The algorithm, from the \Helmholtz Machine" family, attempts to(More)
This study examined the cortical representation of vibrotactile detection in humans using event-related fMRI paired with psychophysics. Suprathreshold vibrotactile stimulation activated several areas, including primary (SI) and second somatosensory cortices (SII/PV). For threshold-level stimuli, poststimulus activity in contralateral and ipsilateral SII/PV(More)
While the understanding of the functional role of different classes of neurons in the awake primary visual cortex has been extensively studied since the time of Hubel and Wiesel (Hubel and Wiesel, 1962), our understanding of the feature selectivity and functional role of neurons in the primary auditory cortex is much farther from complete. Moving bars have(More)
