Experience often does not produce veridical memory. Understanding false attribution of events constitutes an important problem in memory research. “Peak shift” is a well-characterized, controllable phenomenon in which human and animal subjects that receive reinforcement associated with one sensory stimulus later respon... | Neural mechanisms underlying the capacity of memory to be rich in sensory detail are largely unknown.

Variability of single visual evoked potentials evaluated by two new statistical tests | Abstract In this paper the trial-to-trial variability of brain responses (as opposed to the non-event-related background variability) in flash-evoked potential experiments is investigated by means of two new statistical tests, proposed by Mocks et al. (1984). In two groups of normal children, a considerable number of i... | We consider the cross area of the PP_ and PSV_wave window as the best window for joint PP_ and PSV_wave acquisition in VTI media. Within the effective window, the PP_ and PSV_wave's raypathes and phase angles at all reflection points are calculated, and the reflection (or transmission) coefficients' ratios of PSV- to P... | eng_Latn | 10,696 |
Narrow-band oscillations in probabilistic cellular automata. | Dynamical properties of neural populations are studied using probabilistic cellular automata. Previous work demonstrated the emergence of critical behavior as the function of system noise and density of long-range axonal connections. Finite-size scaling theory identified critical properties, which were consistent with ... | Problems associated with the modelling and calculation of quasi-steady-state postfault regimes are considered for abrupt power unbalances. A program permitting calculation of quasi-steady-state postfault regimes with allowance for frequency dynamics and the investigation of their stability is described. Results of calc... | eng_Latn | 10,697 |
Music a scientific art: A call for review of Department of Music, University of Nigeria Nsukka’s curriculum and course outline | Every academic discipline ranging from the Social Sciences, Engineering, Physical Sciences, Arts, and Humanities is typically categorized as either a Science or Arts discipline. While Music is artistic and creative, there is harm in designating music as solely an Arts discipline. It is literally true that music is art,... | Ethological communication permits the exchange of context-specific information among mammals. In recent literature, many investigations have been performed on behavioral responses but little is known about neurophysiological pattern activation. In this study we investigated neuron patterns in response to ultrasound voc... | eng_Latn | 10,698 |
