Infra slow oscillations
Webb1 jan. 2013 · Infra-slow oscillation . This type of oscillatory activity has a period within the range of tens of seconds to a minute (Aladjalova, 1957). Very little is known about the underlying mechanisms of these oscillations but at least some of the factors responsible for their generation could depend on non-neuronal dynamics. Webb8 jan. 2014 · This brain system-specific association indicates that infra-slow scalp potentials are directly associated with the endogenous fluctuations in neuronal activity levels. fbEEG thus yields a noninvasive, high-temporal resolution window into the dynamics of intrinsic connectivity networks.

Webb15 maj 2024 · Here a sharp decrease in neural oscillatory power in the 15 Hz EEG/MEG beta band is observed during movement followed by an increase above baseline on movement cessation. Standard neural mass models cannot readily reproduce this phenomenon, as they cannot track changes of synchrony within a population. http://www.scholarpedia.org/article/Thalamocortical_oscillations
WebbThe results show within-individual alterations in brain activity immediately preceding migraine onset and support the hypothesis that altered regional brainstem function before a migraine attack is involved in underlying migraine neurobiology. Keywords Astrocytes Dorsal pons Infra-slow oscillations Webb2 aug. 2024 · Infra-slow modulation of gamma oscillations was found in the mouse visual system ( Orlowska-Feuer et al., 2024 ). A possible role of neuromodulatory (noradrenergic, serotonergic, dopaminergic, and cholinergic) pathways from the brain stem and basal forebrain in the genesis of synchronous ISFs of the cortical neurons must be taken into …

Such oscillations were first observed in local field potential (LFP) recordings from the rabbit neocortex [1] but have since been observed in several other mammals [2] – [4] …
Webb8 juni 2024 · Whilst infra‐slow oscillation power in the spinal trigeminal nucleus was reduced in all subjects, it was only those subjects that also displayed reductions in thalamic ISOs that experienced pain relief. Furthermore, only those that displayed pain relief also showed reductions in connectivity between the spinal trigeminal nucleus and the thalamus.
