We demonstrate that the irregularity of the scalp EEG response, operationalized as pre-stimulus WPE, offers a clear relationship to spontaneous, pre-stimulus brain states as often described in terms of neural oscillatory power; to the sensory fidelity with which a stimulus is neurally encoded; and to the ensuing perceptual decision upon this stimulus.
applied a machine-learning approach to time-series data from a specific region of interest and demonstrated that single-stimulus brain responses to a specific kind of stimulus could be used to make accurate categorical predictions of disorder status.
This suggests that, during processing of sexual stimuli, brain areas associated with emotional inhibition are activated among women, regardless of the study instructions.
When contrasting word (HA, LA, and NA) with NW stimuli, brain regions activated by word stimuli (all Ps < 0.01) included the left posterior cingulate gyrus, bilateral precuneus, bilateral superior lateral occipital cortex, left superior frontal gyrus, bilateral middle frontal gyrus, and right frontal poles (Table 3, Fig. 3).
A cognitive-based training study by Smith et al. (2009) using primarily auditory stimuli (Brain Fitness Program) showed improvements in both attention and working memory in older, though not necessarily hearing-impaired listeners, compared with an active control group (i.e., the control group had an activity to perform, in this case watching educational digital video discs).
Mediation analysis is ideally suited to investigate stimulus-brain-outcome relationships and has increasingly been applied to neuroimaging data during recent years14,15,16,17,20.
By quantifying how each brain response is involved in the transformation of noxious stimuli into pain, it represents a step further on the way from correlative to mechanistic insights into stimulus-brain-behavior relationships.
For example, some studies present tactile or olfactory stimuli or brain stimulation.
Hemodynamic response is because of any kind of stimulus that brain receives even in resting state.
In contrast, processes associated with response to DNA damage stimulus and brain development were down-regulated.
Myocyte stretch is the main stimulus of brain natriuretic peptide (BNP) synthesis and release.
