Short-latency eye movements evoked by near-threshold galvanic vestibular stimulation.

To investigate whether the primary planes of eye and body responses to galvanic vestibular stimulation (GVS) are congruent, we have measured the binocular, three-dimensional eye movements (scleral coil technique) to bilateral bipolar GVS in six normal ...

Relative effects of harassment, frustration, and task characteristics on cardiovascular reactivity.

Effects of anger induction procedures such as frustration and harassment on cardiovascular reactivity have been demonstrated in a wide range of experimental situations. Similarly, heightened cardiovascular reactivity has been associated with a diverse ...

The relationship between reaction time, error rate and anterior cingulate cortex activity.

Current concepts of cognitive control suggest that the anterior cingulate cortex (ACC) is involved in performance monitoring. This idea is supported by the finding that increased ACC activity is found in situations in which errors are likely to occur, ...

A sedentary day: effects on subsequent sleep and body temperatures in trained athletes.

Exercise effects on sleep in fit healthy people have been difficult to determine because their sleep is close to optimal, leaving little room for improvement. Another method for assessing exercise effects on sleep is to significantly reduce the degree of ...

Cognitive control processes during an anticipated switch of task.

For successful negotiation of our environment, humans must be readily able to switch from one task to another. This ability relies on executive control processes and despite extensive efforts to detail the nature of these processes, there is little ...

Implicit memory bias and trait anxiety: a psychophysiological analysis.

The effect of threatening words and anxiety upon implicit memory performance was investigated. It was predicted that anxious individuals would show a bias to threat-related material. In addition, psychophysiological measures were obtained to assess the ...

Attentional blink modulation in a reaction time task: performance feedback, warning stimulus modality, and task difficulty.

The present research investigated the effect of performance feedback on the modulation of the acoustic startle reflex in a Go/NoGo reaction time task. Experiment 1 (n = 120) crossed warning stimulus modality (acoustic, visual, and tactile) with the ...

Response of human jaw muscles to axial stimulation of the incisor.

The role of periodontal mechanoreceptors (PMRs) in the reflex control of the jaw muscles has thus far been mainly derived from animal studies. To date, the work that has been done on humans has been limited and confined to orthogonal stimulation of the ...

Visual evoked potentials to line- and luminance-defined triangles.

Processing of line- and luminance-defined triangles was investigated by studying visual potentials (VEPs) evoked by triangles. Twenty-six subjects were randomly presented with line, grey, and illusory triangles. Relative to VEPs elicited by grey and ...

Effect of inspiratory muscle strength training on inspiratory motor drive and RREP early peak components.

This study investigated the effect of inspiratory muscle strength training (IMST) on inspiratory motor drive [mouth occlusion pressure at 0.1 s (P(0.1))] and respiratory-related evoked potentials (RREP). It was hypothesized that, if IMST increased ...
