During the last several years, focus of research on resting-state functional magnetic resonance imaging (fMRI) has shifted from analysis connectivity averaged over duration scanning sessions to changes within sessions. Although studies have reported presence dynamic (dFC), statistical assessment results is not always carried out in a sound way and, some studies, even omitted. In this study, we explain why appropriate tests are needed detect dFC, describe how they can be and assess...
Local field potentials (LFPs) reflect subthreshold integrative processes that complement spike train measures. However, little is yet known about the differences between how LFPs and spikes encode rich naturalistic sensory stimuli. We addressed this question by recording from primary visual cortex of anesthetized macaques while presenting a color movie. then determined power at different frequencies represents features in found most informative LFP frequency ranges were 1–8 60–100 Hz. range...
There is growing evidence that several components of the mass neural activity contributing to local field potential (LFP) can be partly separated by decomposing LFP into nonoverlapping frequency bands. Although blood oxygen level-dependent (BOLD) signal has been found correlate preferentially with specific bands LFP, it still unclear whether BOLD relates expressed each band independently others or if, instead, also reflects relationships among different We investigated these issues...
We investigated whether it is possible to infer spike trains solely on the basis of underlying local field potentials (LFPs). Using support vector machines and linear regression models, we found that in primary visual cortex (V1) monkeys, spikes can indeed be inferred from LFPs, at least with moderate success. Although there a considerable degree variation across electrodes, low-frequency structure (in 100-ms range) reasonable accuracy, whereas exact positions are not reliably predicted. Two...
Although recent psychophysical studies indicate that visual awareness and top-down attention are two distinct processes, it is not clear how they neurally dissociated in the system. Using a two-by-two factorial functional magnetic resonance imaging design with binocular suppression, we found visibility or invisibility of target led to only nonsignificant blood oxygenation level-dependent (BOLD) effects human primary cortex (V1). Directing toward away from had much larger robust across all...

1. Tetanizing protocols were used to test whether glycinergic inhibition undergoes long-term plasticity in vivo. For this purpose we studied the evoked disynaptically teleost Mauthner (M) cell by stimulation of posterior branch contralateral VIIIth nerve. The advantage experimental design is that inhibition, which mediated identified second-order commissural interneurons, not contaminated parallel excitation. 2. VIIIth-nerve-evoked inhibitory postsynaptic potentials (IPSPs), are generated at...
