Many offline studies have explored the feasibility of EEG potentials related to single limb movements for a brain-computer interface (BCI) control signal. However, only few functional online… Expand
EEG-based Brain Computer Interfaces
- J. Lehtonen
- Computer Science
This work deals with EEG-based brain computer interfaces, concentrating on the Adap-tive Brain Interface (ABI), which is used in the experimental part of this work. The new ABI equipment, obtained in… Expand
Electrocardiographic criteria for the diagnosis of right ventricular hypertrophy verified at autopsy.
Four commonly used sets of electrocardiographic (ECG) criteria for diagnosing right ventricular hypertrophy (RVH) were tested for sensitivity and specificity in 12 men with isolated RVH, 15 with… Expand
Austin Moore replacement hemiarthroplasty in femoral neck fractures of the elderly.
162 femoral neck fractures were treated with Moore endoprostheses. Primary mortality was eight per cent, and after an average of seven years postoperatively 25 per cent of the patients were alive.… Expand
SPECTRAL SENSITIVITY OF THE STANDING POTENTIAL OF THE HUMAN EYE
It has been known for many years (Kuhne and Steiner, 1881) that illumination alters the standing potential which may be recorded in the eyes of animals, but only recently have Heck and Papst (1957)… Expand

The aim of this study was to determine the diagnostic value of scintigraphy with 99mTc-HMPAO-labelled leukocytes for the detection of prosthetic vascular graft infection. 51 scans were recorded in 19… Expand
Postoperative graft incorporation after aortic reconstruction--comparison between computerised tomography and Tc-99m-HMPAO labelled leucocyte imaging.
Aortic graft infection may result in high mortality ranging up to 88%. Therefore, early diagnosis is imperative in the treatment of this serious complication. Computerised tomography (CT) is… Expand
Sensorimotor cortical activity of tetraplegics during attempted finger movements
We studied the sensorimotor cortical neuromagnetic activity in three tetraplegics during attempted movements of 1) the right 2) the left and 3) both index fingers. Left and right sensorimotor… Expand
