New vistas for α-frequency band oscillations

S Palva, JM Palva - Trends in neurosciences, 2007 - cell.com
The amplitude of α-frequency band (8–14Hz) activity in the human electroencephalogram is
suppressed by eye opening, visual stimuli and visual scanning, whereas it is enhanced …

Long-range temporal correlations and scaling behavior in human brain oscillations

…, VV Nikouline, JM Palva… - Journal of …, 2001 - Soc Neuroscience
The human brain spontaneously generates neural oscillations with a large variability in
frequency, amplitude, duration, and recurrence. Little, however, is known about the long-term …

Phase synchrony among neuronal oscillations in the human cortex

JM Palva, S Palva, K Kaila - Journal of Neuroscience, 2005 - Soc Neuroscience
Synchronization of neuronal activity, often associated with network oscillations, is thought to
provide a means for integrating anatomically distributed processing in the brain. Neuronal …

Neuronal synchrony reveals working memory networks and predicts individual memory capacity

JM Palva, S Monto, S Kulashekhar… - Proceedings of the …, 2010 - National Acad Sciences
Visual working memory (VWM) is used to maintain sensory information for cognitive operations,
and its deficits are associated with several neuropsychological disorders. VWM is based …

Infraslow oscillations modulate excitability and interictal epileptic activity in the human cortex during sleep

S Vanhatalo, JM Palva, MD Holmes… - Proceedings of the …, 2004 - National Acad Sciences
Human cortical activity has been intensively examined at frequencies ranging from 0.5 Hz to
several hundred Hz. Recent studies have, however, reported also infraslow fluctuations in …

Very slow EEG fluctuations predict the dynamics of stimulus detection and oscillation amplitudes in humans

S Monto, S Palva, J Voipio, JM Palva - Journal of Neuroscience, 2008 - Soc Neuroscience
Our ability to perceive weak signals is correlated among consecutive trials and fluctuates
slowly over time. Although this “streaking effect” has been known for decades, the underlying …

Prestimulus oscillations enhance psychophysical performance in humans

…, S Palva, RJ Ilmoniemi, JM Palva - Journal of …, 2004 - Soc Neuroscience
The presence of various ongoing oscillations in the brain is correlated with behavioral states
such as restful wakefulness or drowsiness. However, even when subjects aim to maintain a …

[HTML][HTML] Functional roles of alpha-band phase synchronization in local and large-scale cortical networks

S Palva, JM Palva - Frontiers in psychology, 2011 - frontiersin.org
Alpha-frequency band (8–14 Hz) oscillations are among the most salient phenomena in
human electroencephalography (EEG) recordings and yet their functional roles have remained …

Discovering oscillatory interaction networks with M/EEG: challenges and breakthroughs

S Palva, JM Palva - Trends in cognitive sciences, 2012 - cell.com
The systems-level neuronal mechanisms that coordinate temporally, anatomically and
functionally distributed neuronal activity into coherent cognitive operations in the human brain …

[HTML][HTML] Measurement of excitation-inhibition ratio in autism spectrum disorder using critical brain dynamics

…, E Dallares, S Palva, B Oranje, J Matias Palva… - Scientific reports, 2020 - nature.com
Balance between excitation (E) and inhibition (I) is a key principle for neuronal network
organization and information processing. Consistent with this notion, excitation-inhibition …
