The UCLH Mark 1b is a portable EIT system that can address up to 64 electrodes, which has been designed for imaging brain function with scalp electrodes. It employs a single impedance-measuring circuit and multiplexer so that electrode combinations may be addressed flexibly using software. It operates in the relatively low frequency band between 225 Hz and(More)
An EIT system has been produced that has been optimized for imaging impedance changes with scalp electrodes during brain activity in ambulant subjects. It can record from 225 Hz to 65 kHz, has a small headbox on a lead 10 m long, and has software programmable electrode selection. In calibration experiments in a small cylindrical tank filled with potassium(More)

A linear-array real-time ultrasound scanner with a 5 MHz probe was used to examine the brains of 31 infants born at less than 33 weeks of gestation. The equipment was mounted on a small trolley and the infants could easily be scanned in their incubators. 7 of the 31 infants were shown to have cerebral lesions, including haemorrhages into the germinal layer(More)
This study examines a sample of foster youth at the onset of the transition to adulthood and explores how social bonds are related to the risk of arrest during adulthood. Drawing from official arrest records, event history models are used to examine the time to arrest. Because individuals may be at risk for different types of crime, competing risk(More)
Real-time ultrasound was used to examine the brains of all 95 infants born at less than 33 weeks of gestation who were admitted to the neonatal unit of University College Hospital in 1979. Evidence was obtained which strongly suggested that pneumothorax causes and aggravates haemorrhage into the germinal layer and ventricles of preterm infants.
