Electrophysiological correlates of age and gender perception on human faces.

In a previous experiment using scalp event-related potentials (ERPs), we have described the neuroelectric activities associated with the processing of gender information on human faces (Mouchetant-Rostaing, Giard, Bentin, Aguera, & Pernier, 2000). Here ...

Human cortical response to incoherent motion on a background of coherent motion.

To investigate whether humans achieve a high sensitivity to coherent motion by excluding the response to incoherent motion, we measured the magnetoencephalographic response to the motion of randomly located dots one half of which moved coherently while ...

Gradual increment/decrement of isometric force modulates soleus stretch reflex response in humans.

We investigated how a gradual isometric force-increment and -decrement task modulates the behavior of a soleus stretch reflex. Six healthy subjects performed isometric plantar-flexion torque exertion tasks in which they adjusted the torque level to a ...

Early sensory information processes are enhanced on visual oddball and S1-S2 tasks in Parkinsons disease: a visual event-related potentials study.

To observe sensory and cognitive information processing in Parkinsons disease (PD), 34 PD patients and 26 controls were investigated. A visual oddball paradigm and an S1-S2 paradigm were employed to record the early (P1, N1, P2) and late (N2, P3) ...

Symmetry reversal in schizophrenia.

Schizophrenia is associated with cortical asymmetries concentrated in the left fronto-temporal hemisphere. In order to look for functional asymmetries between the two hemispheres, the stimulus-response times of patients were split into smaller periods ...

The role of prefrontal cortex in verbal episodic memory: rTMS evidence.

Long-term, episodic memory processing is supposed to involve the prefrontal cortex asymmetrically. Here we investigate the role of the dorsolateral prefrontal cortex (DLPFC) in encoding and retrieval of semantically related or unrelated word pairs. ...

Thirty minutes mobile phone use has no short-term adverse effects on central auditory pathways.

OBJECTIVE: To investigate whether pulsed high-frequency electromagnetic field (pulsed EM field) emitted by a mobile phone for 30 min has short-term adverse effects on the human central auditory system. METHODS: We studied the auditory brainstem response ...

Effects of pictorially-defined surfaces on visual search.

Three experiments of visual search for a cube (for a square pillar in Experiment 3) with an odd conjunction of orientation of faces and color (a cube with a red top face and a green right face among cubes with a green top face and a red right face, for ...

Temporal properties of the visual responses to luminance and contrast modulated noise.

Vision is sensitive to first-order luminance modulations and second-order modulations of carrier contrast. Our knowledge of the temporal properties of second-order vision is insufficient and contradictory. Using temporal summation and reaction time ...

Speed tuning of direction repulsion describes an inverted U-function.

Direction repulsion describes the phenomenon in which observers typically overestimate the direction difference between two superimposed motions moving in different directions (Marshak & Sekuler, Science 205 (1979) 1399). Previous research has found ...
