Coherent interaction of dynamical attractors for object-based selective attention.

I investigate essential neuronal mechanisms of visual attention based on object-based theory and a biased-competition scheme. A neural network model is proposed that consists of two feature networks, FI and FII, and one object network, OJ. The FI and FII ...

Internal vs external generation of movements: differential neural pathways involved in bimanual coordination performed in the presence or absence of augmented visual feedback.

It is commonly agreed that a functional dissociation with respect to the internal vs external control of movements exists for several brain regions. This has, however, only been tested in relation to the timing and preparation of motor responses, but not ...

Ecological validity of neurofeedback: modulation of slow wave EEG enhances musical performance.

Biofeedback-assisted modulation of electrocortical activity has been established to have intrinsic clinical benefits and has been shown to improve cognitive performance in healthy humans. In order to further investigate the pedagogic relevance of ...

Electroencephalographic(EEG)-based communication: EEG control versus system performance in humans.

People can learn to control electroencephalographic (EEG) sensorimotor rhythm amplitude so as to move a cursor to select among choices on a computer screen. We explored the dependence of system performance on EEG control. Users moved the cursor to reach ...

Learning to control brain rhythms: making a brain-computer interface possible.

The ability to control electroencephalographic rhythms and to map those changes to the actuation of mechanical devices provides the basis for an assistive brain-computer interface (BCI). In this study, we investigate the ability of subjects to manipulate ...

EEG changes accompanying learned regulation of 12-Hz EEG activity.

We analyzed 15 sessions of 64-channel electroencephalographic (EEG) data recorded from a highly trained subject during sessions in which he attempted to regulate power at 12 Hz over his left- and right-central scalp to control the altitude of a cursor ...

Pitch matching accuracy of trained singers, untrained subjects with talented singing voices, and untrained subjects with nontalented singing voices in conditions of varying feedback.

At a physiological level, the act of singing involves control and coordination of several systems involved in the production of sound, including respiration, phonation, resonance, and afferent systems used to monitor production. The ability to produce a ...

Selective use of visual information signaling objects center of mass for anticipatory control of manipulative fingertip forces.

The present study examines whether visual information indicating the center of mass (CM) of an object can be used for the appropriate scaling of fingertip forces at each digit during precision grip. In separate experiments subjects lifted an object with ...

Bias and sensitivity in the haptic perception of geometry.

Our ability to recognize and manipulate objects relies on our haptic sense of the objects geometry. But little is known about the acuity of haptic perception compared to other senses like sight and hearing. Here, we determined how accurately humans could ...

Neuropsychological impairment in patients with major depressive disorder: the effects of feedback on task performance.

BACKGROUND: Recent evidence suggests that an abnormal response to performance feedback may contribute to the wide-ranging neuropsychological deficits typically associated with depressive illness. The present research sought to determine whether the ...
