The multisensory function of the human primary visual cortex. (2016, background): “…is related to inter-individual differences in baseline visual cortex excitability as indexed by occipital alpha power (Cecere et al., 2015; c.f. Romei et al. (2008b) for a direct link between phosphene perception and alpha power) as well as inter-individual differences in the primary visual…”
The Role of Alpha-Band Brain Oscillations as a Sensory Suppression Mechanism during Selective Attention (2011, background): “In the first such study (Romei et al., 2008a), the researchers applied magnetic pulses to visual cortex of human participants, which resulted in some of the participants experiencing visual percepts (phosphenes).”
To See or Not to See: Pre-stimulus Alpha Phase Predicts Visual Awareness (2009, background): “…have suggested the possible instantiation of attentional influences on visual processing by suppression of rhythmic oscillations in the electroencephalogram (EEG) frequency range (8 –12 Hz) (Worden et al., 2000; Fries et al., 2001; Sauseng et al., 2005; Thut et al., 2006; Romei et al., 2008).”
Shaping Functional Architecture by Oscillatory Alpha Activity: Gating by Inhibition (2010, background): “…network when preparing for upcoming processing. pulsed inHibition It has been proposed that oscillatory alpha activity operates in a phasic manner (Varela et al., 1981; VanRullen and Koch, 2003), and it has been demonstrated that the phase of pre-stimulus alpha oscillations modulates visual…”
Combining non-invasive transcranial brain stimulation with neuroimaging and electrophysiology: Current approaches and future perspectives (2016, unknown): “Using this approach, visual alpha power and phase preceding the TMS pulse have been shown to predict the probability of occipital TMS to evoke phosphenes (Dugue et al., 2011; Romei et al., 2008).”
Increased Alpha-Band Power during the Retention of Shapes and Shape-Location Associations in Visual Short-Term Memory (2011, background): “spontaneous fluctuations in occipital alpha-band power have been found to predict cortical excitability, as indexed by the perception of TMS-induced visual phosphenes (Romei et al., 2008).”
Brain oscillatory substrates of visual short-term memory capacity. (2009, background): “Deactivation or suppression of information processing is associated with oscillatory brain activity in the EEG alpha frequency range (around 10 Hz; see [26–32]).”
Safety, ethical considerations, and application guidelines for the use of transcranial magnetic stimulation in clinical practice and research (2009, unknown): “…et al., 2002; Thut et al., 2003a,b; Thut et al., 2005; Massimini et al., 2005, 2007; Price, 2004; Fuggetta et al., 2005, 2006; Bonato et al., 2006; Van Der Werf et al., 2006; Van Der Werf and Paus, 2006; Morbidi et al., 2007; Litvak et al., 2007; Julkunen et al., 2008; Romei et al., 2008a,b).”
On the Role of Prestimulus Alpha Rhythms over Occipito-Parietal Areas in Visual Input Regulation: Correlation or Causation? (2010, background): “…alpha power also covaries with the excitability of the visual cortex, tested by single-pulse transcranial magnetic stimulation (TMS) over the occipital pole (Romei et al., 2008), and is predictive of forthcoming perception (Ergenoglu et al., 2004; Hanslmayr et al., 2007; van Dijk et al., 2008).”
The Theta-Gamma Neural Code (2013, unknown): “Further evidence that high alpha power is associated with inhibition is that firing rates, phosphene detection, and the BOLD signal are all reduced (Haegens et al., 2011; Ritter et al., 2009; Romei et al., 2008).”
The Phase of Ongoing EEG Oscillations Predicts Visual Perception (2009, background): “…et al., 2000; Sauseng et al., 2005; Thut et al., 2006; Fries et al., 2008), and perceptual performance (Ergenoglu et al., 2004; Gonzalez Andino et al., 2005; Babiloni et al., 2006; Thut et al., 2006; Womelsdorf et al., 2006; Hanslmayr et al., 2007; Romei et al., 2008; van Dijk et al., 2008).”
Globally elevated excitation–inhibition ratio in children with autism spectrum disorder and below-average intelligence (2021, background): “Indeed, ‘alpha states’ index reduced cortical excitability (40, 41) and are dominated by currents and firing in supragranular cortical layers (62), which display steeper 1/f slope than the other cortical layers, presumably due to longer”
Separating Neural Oscillations from Aperiodic 1/f Activity: Challenges and Recommendations (2021, background): “I balance (Romei et al., 2008) and (Iemi et al., 2019) found alpha- and beta-band power to predict suppression of ERP-components, which was interpreted as increased inhibition.”
Rhythmic TMS as a Feasible Tool to Uncover the Oscillatory Signatures of Audiovisual Integration (2023, background): “Germane to this notion, it could be argued that active rhTMS tailored at the IAF should have prompted an increase in alpha power and a reduction in cortical excitability, which might have, in turn modulated the probability of reporting the illusion [27,28,42].”
