MRI scanners can measure very low signal intensities. In the optimal case, only the thermal noise of the patient should limit the received signal-to-noise ratio (SNR). Spurious signals received from PET detector electronics will directly deteriorate the SNR or show up as artifacts in the MR im...
While these basic cognitive and affective processes may influence the expression of the FN, research on individual differences in reward sensitivity has also been theorized to play a role in general approach and withdraw behaviors and responses to affective stimuli, which are linked to trait levels ...
We read the EEG off line and we marked the events such as artifacts before visualizing them through the 2-D topoplot map in order to topographically characterize them. We performed the same for sleep figures. We were able to recognize eye and mimic artifacts, electromyographic ones due to ...
Studies using functional MRI (fMRI) and intracranial EEG (iEEG) likewise have suggested that the left perisylvian regions play predominant roles in the processing of spoken language. Tasks requiring sentence comprehension were reported to elicit hemodynamic and neuronal activation in the left perisylvian ...
The sensations of arousal are both pleasurable in-and-of-themselves and also allow for more effective sexual stimulation (e.g. via erection or lubrication). That is, the affordances (Gibson, Citation1977) and signal transduction properties of an aroused body are better suited for facilitating ...
There are many unresolved issues with respect to the nature and interpretation of dynamic metrics (Lurie et al., 2020), and the contribution of sampling variability and head motion artifacts to these findings have been noted (Laumann et al., 2017). New dynamic FC analysis techniques are ...

Artifacts similar to those seen in a lab environment can also be expected in EEG recorded in the scanner, for example, eye movements, muscle tension, or electrical interference from devices used within the scanner room; however, there are artifacts that are specific to the MR environment that ...
CSF flow artifacts can mimic LM on MRI, especially in the dorsal epidural space with a wide spinal canal. However, their epicenter in the subarachnoid space location can help distinguish them from true lesions [81,83]. MRI with 3D sequences offers superior sensitivity compared to CSF cytology,...
