Brain Computer Interfaces (BCI) represent a new communication option for those suffering from neuromuscular impairment that prevents them from using conventional augmented communication methods. This new approach has been developing quickly during the last few years, thanks to the increasing of computational power and the new algorithms for signal(More)
To describe results of training and 1-year follow-up of brain-communication in a larger group of early and middle stage amyotrophic lateral sclerosis (ALS) patients using a P300-based brain-computer interface (BCI), and to investigate the relationship between clinical status, age and BCI performance. A group of 21 ALS patients were tested with a BCI-system(More)
Brain-computer interface (BCI) technology has been used for rehabilitation after stroke and there are a number of reports involving stroke patients in BCI-feedback training. Most publications have demonstrated the efficacy of BCI technology in post-stroke rehabilitation using output devices such as Functional Electrical Stimulation, robot, and orthosis. The(More)
BACKGROUND Evoked potentials allow one to assess functional integrity of sensory pathways projecting to primary sensory cortices and event-related potentials assess higher order cortical functions associated with stimulus detection and decision-making. Evoked and event-related potentials have been used to predict emergence from coma. This study aimed to(More)
The aim of the present study is to compare different visual elicitation paradigms exploitable in a Virtual Environment in order to establish whether the BCI is affected by the structure of the elicitation paradigm, the modalities of stimulus presentation, and the complexity of stimulus recognition and semantic processing. We have developed a device which(More)
BACKGROUND Repetitive transcranial magnetic stimulation (rTMS) induces prolonged functional changes in the cerebral cortex in normal conditions and in altered states of consciousness. Its therapeutic effects have been variously documented. OBJECTIVE The aim of this study was to investigate the reactivity of electroencephalography (EEG) and the clinical(More)
Aim of this study is to investigate working memory functions in nondemented patients with amyotrophic lateral sclerosis (ALS) using neuropsychological testing and auditory event-related potentials. Twenty-four patients with ALS and 17 age- and education-matched controls underwent a comprehensive neuropsychological assessment, with particular emphasis on(More)
The paper presents some speculations on the loss of voluntary responses and operant learning in long-term paralysis in human patients and curarized rats. Based on a reformulation of the ideomotor thinking hypothesis already described in the 19th century, we present evidence that instrumentally learned responses and intentional cognitive processes extinguish(More)
