Journal ArticleDOI
Striate cortex increases contrast gain of macaque LGN neurons.
TL;DR: It is shown that the corticofugal projections from the striate cortex to the lateral geniculate nucleus robustly and multiplicatively enhance the responses of parvocellular neurons by over two-fold in a contrast-independent manner at all but the lowest contrasts.
Journal ArticleDOI
Spatial Receptive Field Organization of Macaque V4 Neurons
TL;DR: A framework for a new class of neural network models for the spatial RF organizations of prototypic V4 neurons is proposed, namely that classes of stimulus configurations that enhance areal summation while reducing suppressive interactions between excitatory inputs will evoke especially robust responses.
Journal ArticleDOI
Emd approach to multichannel eeg data — the amplitude and phase components clustering analysis
TL;DR: A decomposing of recorded channels into intrinsic mode functions (IMF) which are a result of empirical mode decomposition (EMD) extended to multichannel analysis presents novel and interesting results on human mental and cognitive states estimation based on analysis of stimuli-related IMF components.
Journal ArticleDOI
Localization of the subthalamic nucleus in Parkinson disease using multiunit activity.
Peter Novak,Andrzej W. Przybyszewski,Andrei Barborica,Paula D. Ravin,Lee Margolin,Julie G. Pilitsis +5 more
TL;DR: The QD gives objective coordinates of the STN borders at high precision and may be more accurate than IOM and Prospective blinded comparative studies where the DBS leads will be placed using either QD or IOM are warranted.
Journal ArticleDOI
Responses of retinal ganglion cells to eyeball deformation: a neurophysiological basis for "pressure phosphenes".
TL;DR: By means of microelectrodes, the activity of single neurons (on-center, off-center ganglion cells, latency class I and class II neurons) was recorded from the optic tract of anesthetized cats, demonstrating that eyeball deformation can be used as an independent tool in transmitter studies of the retina.
