Menstrual cycle-dependent neural plasticity in the adult human brain is hormone, task, and region specific.

In rodents, cyclically fluctuating levels of gonadal steroid hormones modulate neural plasticity by altering synaptic transmission and synaptogenesis. Alterations of mood and cognition observed during the menstrual cycle suggest that steroid-related ...

Peripheral and segmental spinal abnormalities of median and ulnar somatosensory evoked potentials in Hirayamas disease.

OBJECTIVES: To investigate the origin of juvenile muscle atrophy of the upper limbs (Hirayamas disease, a type of cervical myelopathy of unknown origin). SUBJECTS: Eight male patients were studied; data from 10 normal men were used as control. METHODS: ...

Characterizing the time course of an implicature: an evoked potentials study.

This work employs Evoked Potential techniques as 19 participants are confronted with sentences that have the potential to produce scalar implicatures, like in Some elephants have trunks. Such an Underinformative utterance is of interest to pragmatists ...

Efficiency and internal noise for detection of suprathreshold patterns measured using simple reaction time.

Studies of the detection of simple visual patterns at threshold contrast have found that human performance is limited by the addition of internal noise and by the sub-optimal sampling efficiency of the visual system. Many common visual tasks require the ...

Differences in the perception and time course of syntactic and semantic violations.

A reading time and an ERP experiment conducted in Italian investigated the parsers responses to a syntactic violation (subject-verb number agreement) and to a semantic violation (subject-verb selectional restriction), examining the time course of ...

Age-related slowing of digit symbol substitution revisited: what do longitudinal age changes reflect?

A previous investigation reported that cross-sectional age differences in Digit Symbol Substitution (DSS) test performance reflect declines in perceptual processing speed. Support for the tenability of the processing speed hypothesis requires examining ...

Cerebral correlates of explicit sequence learning.

Using positron emission tomography (PET) and regional cerebral blood flow (rCBF) measurements, we investigated the cerebral correlates of consciousness in a sequence learning task through a novel application of the Process Dissociation Procedure, a ...

Attention and movement-related motor cortex activation: a high-density EEG study of spatial stimulus-response compatibility.

Visual spatial attentional activation of motor areas has been documented in single cell neurophysiology and functional imaging studies of the brain. Here, we investigate a candidate event-related brain potential representing visuospatial attentional ...

STIVID: A VBSCRIPT-based program for adding visual and auditory stimuli on videotapes.

Some psychological experiments require placement of visual and auditory stimuli on predefined frames in a videotape. We introduce STIVID (STImuli on VIDeo) as a method of performing this task STIVID can add images, words, simple shapes, and audio tones ...

A physiological correlate of the "Zoom Lens" of visual attention.

Attending a certain region in space enhances activity in visual areas retinotopically mapped to this region; stimuli presented in this region are preferentially processed. The zoom lens model of visual attention proposes that the attended region can be ...
