Dual Process Coding of Recalled Locations in Human Oscillatory Brain Activity

Oscillatory Brain Activity in Human Affective Stimulus Processing

Oscillatory Brain Activity as underlying Neural Mechanism of Human Memory

It has been proposed that associative learning is accomplished by the formation of cell assemblies and synchronousactivity among the neurons of such an assembly. Induced gamma band responses (GBRs) and phase synchrony betweenelectrode sites are discussed as a signature of activity within a cell assembly. To examine the activation of this networkdue to memory recall, a paired associa...

Oscillatory brain activity in memory disorders

Neuronal oscillations are thought to underlie interactions between distinct brain regions required for normal memory functioning. This study aimed at elucidating the neuronal basis of memory abnormalities in neurodegenerative disorders. Magnetoencephalography (MEG) was used to measure oscillatory brain signals in patients with Alzheimer’s disease (AD), a neurodegenerative disease causing progre...

comparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.

heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...

Speech Rhythms and Multiplexed Oscillatory Sensory Coding in the Human Brain

Cortical oscillations are likely candidates for segmentation and coding of continuous speech. Here, we monitored continuous speech processing with magnetoencephalography (MEG) to unravel the principles of speech segmentation and coding. We demonstrate that speech entrains the phase of low-frequency (delta, theta) and the amplitude of high-frequency (gamma) oscillations in the auditory cortex. P...
