An event-related potentials study on selective attention modulated by vestibular stimulation.

Objective: To explore the dynamic change of the late attentional selection process under linearly varied vestibular stimuli using event-related potentials (ERPs) technique.

Method: Thirty-three subjects participated in the experiment. They were exposed to vestibular stimulation of constant angular velocity rotation (10 degrees/s) and four levels of constant angular acceleration rotation, the acceleration was 0.

The effects of vestibular stimuli on brain cognitive processing: an ERP study.

Cognition impairment caused by space motion sickness often is a risk of spaceflight. So the dynamic changes of pattern of brain cognitive processing under varied vestibular stimuli was explored using event-related potentials. Vestibular stimulation was produced by rotary chair and varied linearly, i.

[Application prospect of human-artificial intelligence system in future manned space flight].

Objective: To make the manned space flight more efficient and safer, a concept of human-artificial (AI) system is proposed in the present paper.

Method: The task of future manned space flight and the technique requirement with respect to the human-AI system development were analyzed.

Result: The main points are as follows: 1)Astronaut and AI are complementary to each other functionally; 2) Both symbol AI and connectionist AI should be included in the human-AI system, but expert system and Soar-like system are used mainly inside the cabin, the COG-like robots are mainly assigned for EVA either in LEO flight or on the surface of Moon or Mars; 3) The human-AI system is hierarchical in nature with astronaut at the top level; 4) The complex interfaces between astronaut and AI are the key points for running the system reliably and efficiently.

[WMN: a negative ERPs component related to working memory during non-target visual stimuli processing].

Objective: To study non-target stimuli processing in the brain.

Method: Features of the event-related potentials (ERPs) from non-target stimuli during selective response task (SR) was compared with that during visual selective discrimination (DR) task in 26 normal subjects. The stimuli consisted of two color LED flashes (red and green) appeared randomly in left (LVF) or right (RVF) visual field with same probability.

[Effect of extremely low frequency magnetic field on the focal brain injury in rats].

Objective: To examine the effect of extremely low frequency magnetic field (ELMF) on the brain trauma in rats.

Method: Using the focal left-brain cortex contusion model, rats were divided into two groups, ELMF group (3 d and 8 d) and control group (3 d and 8 d), ELMF stimulations were given after the brain trauma provided by a coil (phi 10 cm) which was driven by 15 Hz sinusoidal signals so that ELMF strength of 18 mT at the midpoint was obtained. The morphologic changes were observed in these groups.

[Two types of event-related brain slow potentials in auditory location discrimination (correction of dicrimination) task].

Objective. To study the difference between two types of event-related brain potentials (ERPs) in auditory location discrimination task. Method.

[N2 effect on non-target event-related brain potentials during auditory selective response task].

Objective. To study N2 effect and its feature on non-target event-related brain potentials during auditory selective attention. Method.

[Effects of task load on early and late components of auditory event-related brain potentials].

Objective: To study the effects of task load on early and late components of auditory event-related potentials.

Method: The subjects were 12 healthy right-handed volunteers aged 20-23 years. The stimuli were auditory signals of two kinds of tones and appeared randomly from four speakers located on the left-front, left-rear, right-front and right-rear over the head of the subject.
