Effects of hormone replacement therapy on perceptual and cognitive event-related potentials in menopausal insomnia.

The influence of a combined estrogen-progestin regimen (Climodien, Lafamme) on auditory event-related potentials (ERPs) was investigated in a double-blind, placebo-controlled, comparative, randomized 3-arm trial phase (Climodien 2/3=estradiol valerate 2 ...

Respiratory-related evoked potential and upper airway transmural pressure change by using the negative expiratory pressure (NEP) device.

OBJECTIVE: Several studies have previously shown respiratory related evoked potentials (RREP) in humans elicited by mechanical stimuli applied on upper airways (UA). According to us, heterogeneous findings, concerning latencies and amplitudes, have been ...

Early postnatal development of sensory gating.

Sensory gating represents the nervous systems ability to inhibit responding to irrelevant environmental stimuli. In order to characterize the early development of acoustic sensory gating, suppression of auditory evoked potential component P1 (i.e. P50) ...

Structure and limited capacity in verbal working memory: a study with event-related potentials.

In order to test recent claims about the structure of verbal working memory, two ERP experiments with Dutch speaking participants were carried out. We compared the ERP effects of syntactic and semantic mid-sentence anomalies in subject and object ...

Selective attention affects human brain stem frequency-following response.

Selective attention modifies long-latency cortical event-related potentials. Amplitudes are typically enhanced and/or latencies reduced when evoking stimuli are attended. However, there is controversy concerning the effects of selective attention on ...

Latency of the pupil light reflex: sample rate, stimulus intensity, and variation in normal subjects.

PURPOSE: To investigate the clinical usefulness of the latency of the pupil light reflex by optimizing its measurement, characterizing its variability, and determining the sensitivity of pupil latency as a function of stimulus input in normal subjects. ...

Physical activity improves gaze and posture control in the elderly.

Ageing is associated with a decrease in the quality of balance regulation, in particular through dysfunctions of gaze control and postural stabilization, which results in an increased risk of falling. Conversely, the practice of physical and sporting ...

N400 abnormalities in unmedicated patients with schizophrenia during a lexical decision task.

A lexical decision task was used to investigate semantic processing in schizophrenia. Eighteen unmedicated schizophrenics and 18 gender/age-matched controls were tested. Subjects were visually presented with pairs of words. The target word (S2) was ...

A subsequent-memory effect in dorsolateral prefrontal cortex.

The importance of brain regions for long-term memory encoding has been examined by comparison of encoding-related neural activity on trials in which successful recollection subsequently occurred to the encoding-related activity on trials in which ...

Modulation of neural activity during object naming: effects of time and practice.

Repeated exposure to objects improves our ability to identify and name them, even after a long delay. Previous brain imaging studies have demonstrated that this experience-related facilitation of object naming is associated with neural changes in ...
