Presidential Address 2011: Autonomic modes of control and health
AbstractUnderstanding psychosomatic relations, and their implications for heath, is importantly dependent on our conceptual and measurement models. The historical view of reciprocal control of the autonomic branches is applicable in some contexts, but not others. Control of the autonomic branches can vary reciprocally, independently, and even coactively. Assessment of sympathovagal balance, based on a reciprocal model of regulation of the autonomic branches, may have applications in orthostatic contexts and in insulin resistance in diabetes. However, it does not adequately capture the pattern of autonomic control that is r...

Latency of skin conductance responses across stimulus modalities
AbstractReproducibility and methodological robustness are of major concern in research today, also with respect to autonomic measures. Quantification of skin conductance responses (SCRs), for instance, relies on response characteristics such as response onset (i.e., latency), which were established more than four decades ago by using paper ‐pencil methods. Since then, data acquisition has advanced to digital methods, improving sampling rates up to 100,000 samples/second and thereby improving resolution and accuracy. Here, SCR latency as a major characteristic for defining an appropriate response window is revisited by us...

Cerebral blood flow modulations during antisaccade preparation in chronic hypotension
This study investigated cerebral blood flow modulations in hypotension during a precued antisaccade/prosaccade task requiring the executive function of proactive inhibition in addition to preparatory attention. Using functional transcranial Doppler sonography, bilateral blood flow velocities in the middle cerebral arteries (MCA) were recorded in 39 hypotensive and 40 normotensive participants. In the task, a stimulus appeared left or right of a fixation point 5  s after a cuing stimulus; subjects had to move their gaze to the mirror image position of the stimulus (antisaccade) or toward it (prosaccade control condition). ...

Sequential processing in the classic oddball task: ERP components, probability, and behavior
This study compared the ERP components and behavior associated with the auditory equiprobable and classic oddball tasks, to relate the cognitive processing stages in those paradigms and continue the development of the sequential processing schema. Target and nontarget ERP data were acquired from 66 healthy young adults (Mage = 20.1,SD = 2.4  years, 14 male) who completed both equiprobable (targetp = 0.5) and oddball tasks (targetp = 0.3). Separate temporal PCAs were used to decompose the ERP data in each task and condition, and the similarity of the components identified in each condition was examined between tasks. P...

Hypomania and depression associated with distinct neural activity for immediate and future rewards
AbstractBipolar spectrum and unipolar depressive disorders have been associated with distinct and opposite profiles of reward ‐related neural activity. These opposite profiles may reflect a differential preexisting vulnerability for both types of disorders. In support, recent ERP studies find that, following reward feedback, a larger reward positivity (RewP) is associated with greater vulnerability for bipolar spectrum d isorders, whereas a smaller RewP is associated with greater vulnerability for depression. However, prior studies have investigated only immediate rewards and have not examined dimensions of both bipolar ...

Intensity expectation modifies gustatory evoked potentials to sweet taste: Evidence of bidirectional assimilation in early perceptual processing
AbstractExpectations can affect subjective sensory and hedonic ratings of tastes, but it is unclear whether they also shape sensory experience at a perceptual level. The neural correlates of the taste ‐expectancy relationship were explored through EEG analysis. Using a trial‐by‐trial cueing paradigm, lingual delivery of 0.05 M or 0.3 M sucrose solutions was preceded by congruent or incongruent visual cues designed to promote anticipation of either a low‐sweet or high‐sweet solution. W hen participants were cued to expect low‐sweet, but received high‐sweet (incongruent cue), intensity ratings for high‐swee...

The independency of the Bereitschaftspotential from previous stimulus ‐locked P3 in visuomotor response tasks
AbstractThe Bereitschaftspotential (BP) and the P3 are well ‐known ERPs usually observed during self‐paced and externally triggered tasks. Recently, the BP was also detected in externally triggered tasks before stimulus onset. However, doubts have been raised about the authenticity of the BP in these tasks due to possible overlaps with the previous trial P3 (hereinafter s‐1 P3). Here, we aim to test the authenticity of the BP in externally triggered tasks by comparing ERPs obtained during two visuomotor response tasks with different interstimulus intervals (ISIs) allowing (short‐ISI; 1,000–2,000 ms) or not (long...

Covert singing in anticipatory auditory imagery
AbstractTo date, several fMRI studies reveal activation in motor planning areas during musical auditory imagery. We addressed whether such activations may give rise to peripheral motor activity, termed subvocalization or covert singing, using surface electromyography. Sensors placed on extrinsic laryngeal muscles, facial muscles, and a control site on the bicep measured muscle activity during auditory imagery that preceded singing, as well as during the completion of a visual imagery task. Greater activation was found in laryngeal and lip muscles for auditory than for visual imagery tasks, whereas no differences across tas...
