Current understanding of feature binding remains controversial. Studies involving mismatch negativity (MMN) measurement show a low level of binding, whereas behavioral experiments suggest a higher level. We examined the possibility that the two levels of feature binding coexist and may be shown within one experiment. The electroencephalogram was recorded(More)
Frequency-temporal electroencephalogram (EEG) reactions to hypogravity were studied in 7 male subjects at the age of 20 to 27 years. The experiment was conducted using dry immersion (DI) as the best known method of simulating the space microgravity effects on the Earth. This hypogravity model reproduces hypokinesia, i.e. the weight-bearing and mechanic load(More)
In order to study spontaneous attentional lapses the experimental task was used that created a moderately high attentional load and involved response choice based on stimulus feature conjunction. The participant's average correct response rate was 85.1%; they made errors in 9.6% trials and response omissions in 5.4% trials. Peak N1 of the evoked potential(More)
The characteristics of prepulse inhibition (PPI) and prepulse facilitation (PPF)of the acoustic startle reaction (ASR) were studied in healthy subjects and patients with schizophrenia. Testing was performed in accordance with the recommendations of the International Schizophrenia Genetics Consortium. Patients showed a deficit in PPI with a prepulse interval(More)
Prepulse modification of acoustic startle reaction (ASR) was studied in patients with schizophrenia and healthy controls according to the protocol recommended by the Consortium on the genetics of schizophrenia. Patients displayed the reduced ASR magnitude of prepulse inhibition (PPI) and increased startle latency prepulse facilitation (PPF) at 60 ms lead(More)
