Speed of processing in the primary motor cortex: A continuous theta burst stimulation study
2014, Behavioural Brain ResearchCitation Excerpt :Specifically, a reduction in the required threshold for activation or an increase in the rate of rise excitability in the motor cortex in temporally urgent situations may assist in reducing reaction time based on the demands of the stimulation. Stimulus intensity has long been demonstrated to have a profound effect on reaction time [16–20], although the direct contribution of central nervous system (CNS) areas that may be involved in this intensity-based modulation has not been fully understood. Previous work utilizing electroencephalography (EEG) demonstrated that event related potentials (ERP) relative to a high intensity, non-noxious electrical stimulation evoked a large negativity centralized over pre-motor areas approximately 75 ms prior to the onset of muscle activity in a simple reaction time task [21].
Does temporal preparation increase the rate of sensory information accumulation?
2011, Acta PsychologicaCitation Excerpt :Hence, in this regard, both accounts lead to the same conclusion, that is that temporal preparation does not affect the rate of sensory accumulation. However, given that stages are carried out strictly serially – as assumed in serial stage models – and stimulus intensity affects perceptual processing even at the retinal level (e.g., Mansfield & Daugman, 1978; Vaughan, Costa, & Gilden, 1966; see, however, Ulrich & Stapf, 1984), temporal preparation may affect a stage after sensory information accumulation, that is late perceptual or even post-perceptual stages (cf. Hackley, 2009; Los & Schut, 2008). Based on the present results, one cannot rule out such a post-accumulation account.
A generalized method to estimate waveforms common across trials from EEGs
2010, NeuroImageCitation Excerpt :We assumed that the delays of waveform-1s slightly fluctuate after the stimulus onsets and the delays of waveform-2s in the Go trials slightly fluctuate around the response onsets. Therefore, based on reports that examined the variable latencies of visual evoked potentials (Mihaylova et al., 1999; Vassilev et al., 2002; Vaughan et al., 1966), we searched for the delays of waveform-1s from 0 to 50 ms after the stimulus onsets and the delays of waveform-2s in the Go trials from - 25 to 25 ms after the response onsets. We searched for the delays of the other waveforms setting the initial delays to Gaussian random numbers [mean = 180 (ms), SD = 50 (ms)].
Temporal decomposition of EEG during a simple reaction time task into stimulus- and response-locked components
2008, NeuroImageCitation Excerpt :Then, we adopt the assumption of this study, which is that the stimulus- and response-locked components are overlapping and the delay of the response-locked component is somehow responsible for the variability of the RTs. However, it is not appropriate additionally to assume that the waveforms of the stimulus- and response-locked components are constant or independent of each other, because, in some cases, peak amplitudes or latencies in the components may vary more or less with RTs (Mihaylova et al., 1999; Vassilev et al., 2002; Vaughan et al., 1966). Note that s(t) and r(t) in Eq. (1) represent the average waveforms of the stimulus- and response-locked components, and that trial-to-trial variability of these components is included in the noise term of Eq. (1).
