(1) By contrast, there was a highly significant correlation between the latency of principal cell EPSPs and IPSPs, in support of a feedforward model of inhibition.
(2) The central features of the diagram are a positive dopaminergic feedforward process and a positive feedback mechanism mediated by extrasynaptic substance P diffusing from striatal terminals to dopaminergic dendrites of the zona compacta neurons.
(3) Previous studies have indicated that motor center ("feedforward") activity is important for hormonal and metabolic responses to exercise.
(4) DLR receives only sparse feedforward input from V II, but stronger input from DLC.
(5) The results of a series of benchmarking studies based upon artificial statistical pattern recognition tasks indicate that the proposed architecture performs significantly better than conventional feedforward classifier networks when the decision regions are disjoint.
(6) The response of dentate granule cells to this stimulation was assumed to reflect activity in the larger hippocampal network, because other subpopulations of neurons activated monosynaptically and polysynaptically within the hippocampal formation contribute to granule cell excitability through multiple feedforward and feedback pathways.
(7) Furthermore, the proximal location of the clutch-cell inputs to the labelled dendrite suggests a strategic siting of intracortical feedforward inhibition.
(8) Cobalt at 0.5 mM thus blocks the light-evoked action of the cone feedback synapse while sparing feedforward synaptic transmission from cones to horizontal cells.
(9) Effects of dynamic coupling, gravity, inertia and the mechanical impedances of the segments of a multi-jointed arm are shown to be neutralizable through a reflex-like operating three layer static feedforward network.
(10) In fast movements, all the body segments were displaced at the same time, which suggests a feedforward control, whereas in slow movements, onset of displacement of the body segments was found to take place sequentially in a cranio-caudal direction.
(11) The present study showed that, even under irregular stimulations, pursuit eye movement is regulated in a feedforward manner by the perceptual analysis of the preceding target motion, and that corrective saccades in pursuit eye movement correspond to those observed in step displacements, except for the programming on the basis of the changing rate of position error.
(12) The baseline response also showed some indication of depression, particularly in the dentate gyrus kindled group, raising the possibility that feedforward inhibition had also been potentiated.
(13) In the previous paper of this series, I showed that such cells emerge spontaneously during the development of a simple multilayered network having local but initially random feedforward connections that mature, one layer at a time, according to a simple development rule (of Hebb type).
(14) Feedforward stabilization of hand position was observed in all subjects.
(15) Results are given for (a) a simple linear pathway without feedback or feedforward regulation, and (b) a linear pathway with feedback inhibition.
(16) One interpretation of this pattern of results is that the output of CA1 pyramidal cells is maintained roughly constant in spite of reduced input from CA3 because of a proportional reduction in feedforward inhibition.
(17) The control of depth of anaesthesia has been viewed as a control-system problem the solution of which can involve both feedback and feedforward techniques.
(18) The GMR models are compared to autoregressive transfer function models and feedforward back propagation neural network models.
(19) To determine whether feedforward control of liver glycogenolysis during exercise is subject to negative feedback by elevated blood glucose, glucose was infused into exercising rats at a rate that elevated blood glucose greater than 10 mM.
(20) Possible biological implications of these results are destabilization of metabolic units by transport processes and feedforward catalysis.
