The effect of auditory signal delay on audio-visual perception of videotaped sentence lists by Ss with normal hearing was measured. The test material consisted of sentences read by a man, with or without a picture representing as context one of the key words in each sentence. In Exper. I, 12 Ss (6M, 6F), inexperienced with lipreading, were presented test(More)
The passive electrotonic parameters of nerve cells in the dentate gyrus of the rat were studied in vitro. Intracellular recordings from 30 granule cells and 3 pyramidal basket cells followed by intracellular injection of horseradish peroxidase (HRP), allowed calculations of input resistance (RN), membrane time constant (tau m), electrotonic length (L),(More)
OBJECTIVE To demonstrate the viability of bone conduction as a novel method for stimulation of distortion product otoacoustic emissions (DPOAEs). DESIGN DPOAEs were recorded from a single ear of 23 normally hearing adults using bone and air conduction for the delivery of stimulus tones. Exploration of the input-output function was performed by varying(More)
We investigated whether pitch-synchronous neural activity could be recorded in humans, with a natural vowel and a vowel in which the fundamental frequency was suppressed. Small variations of speech periodicity were detected in the evoked responses using a fine structure spectrograph (FSS). A significant response (P < 0.001) was measured in all seven normal(More)
A quantitative model of the peripheral bladder control system of the dog is developed. This model is based on the experimental characterisation of the detrusor muscle and the urethra in 25 female dogs. Intravesical pressure, urinary flow and bladder volume were simultaneously recorded during electrical bladder stimulation, and, from these data, a dynamic(More)
Hospital management teams receive voluminous data from a wide variety of sources, but are unable to distill the essential data they require to make good decisions. We have used a methodology which helps teams define and use important management data coupled with an information system that makes this data accessible. Results of our evaluation indicate that(More)

An analysis of paper-based charting was carried out at Sunnybrook Health Sciences Center as a prelude to developing a strategic plan to implement an electronic patient record. A relational model of the Sunnybrook paper chart was developed, describing each of its forms in terms of specific data fields. Three hundred and forty nine different forms are in(More)
A measuring system used to monitor the orthogonal stresses and strains in the plane of the passive canine diaphragm musclein vivo is described. The system consists of four topically applied force-displacement transducers, a laser-camera subsystem to determine the local radii of curvature and an abdominally situated pressure transducer. Experimental results(More)
