Introduction The Emotiv EPOC headset (http://emotiv.com/) has become one of the leading BCI equipment available today as a result of its low-cost (consumer edition for $300-400, research edition for $500) and features (14 EEG channels plus two references, inertial sensors, wireless connectivity, etc.). Although it has been integrated in a vast number of BCI applications, yet, its use for resear...

Cross sections for K p charge exchange, based on new data equal in statistics to the sum of those of all previous determinations below 300 MeV/c, are presented. The results confirm an earlier observation by this collaboration that the previous measurements of these cross sections at low momentum were significantly underestimated. Evidence for the presence of P wave scattering is presented.

Schizophrenia patients and a subset of patients with bipolar disorder suffer from psychosis. Both disorder have been found to have shared genetic risk factors. In order to assess these claims further, endophenotypes for these disorders need to be established. Electroencephalography provides a means for measuring low level auditory processing through event related potentials. In the study a dich...

An EEG-based brain–computer system can be used to control external devices such as computers, wheelchairs or Virtual Environments. One of the most important applications is a spelling device to aid severely disabled individuals with communication, for example people disabled by amyotrophic lateral sclerosis (ALS). P300-based BCI systems are optimal for spelling characters with high speed and ac...

Evidence of hemispheric asymmetries in schizophrenia has been reported from different research areas. Asymmetries in evoked potential P300 topography are still controversial because of inconsistent findings. In the present study. previous results of abnormal lateralization of P300 were replicated in stabilized residual Schizophrenie patients. Auditory P300 was recorded during an odd ball task i...

The auditory P300 evoked potential was recorded in 36 subjects: left(LH) and right-handed (RH) schizophrenic males and LH and RH normal controls. LH and RH normals showed no asymmetry in P300 scalp topography. LH and RH schizophrenics, however, showed lateralized asymmetries in temporal scalp regions: left < right P300 voltage asymmetry in RH schizophrenics and left > right P300 voltage asymmet...

The Practice of Ethics is an introduction to moral philosophy. It starts from a series of practical questions, which range from the personal and picayune (‘If a friend has had an awful haircut and asks your opinion of his new hairdo, should you lie to avoid hurting his feelings?’) to political, life-and-death issues (‘Is the death penalty justified?’). The book uses these questions as routes in...
