1. Using the isolated medulla and spinal cord of the neonatal rat, the response to CO2-induced changes in superfusate pH was examined in whole cell and perforated patch recordings from ventral medullary neurones which were identified by injection of Lucifer Yellow. The respiratory response to changing the CO2 concentration (from 2 to 8%) consisted of an(More)
We have used the isolated brainstem-spinal cord preparation of the neonatal rat to study the effects of theophylline on the ventilatory response to hypoxia. The brainstem-spinal cord was isolated from neonatal rats (0-4 days) and superfused with mock cerebrospinal fluid (CSF), equilibrated with a gas mixture (FO2, 0.90; FCO2, 0.02; FN2, 0.08; control CSF)(More)
The main purpose of this study was to evaluate the role of the pons in hypoxic respiratory depression (HRD) of the neonatal rat. Experiments were conducted using the isolated brainstem-spinal cord preparation of the neonatal rat (1-3 days old). The brainstem was transected at various levels. We found that ablation of the diencephalon decreased respiratory(More)
THE ipsilateral and contralateral corticocortical connections to the fifth somatosensory area (SV) in the feline cortex were determined from the location of retrogradely labelled cells following a single injection of HRP into SV. The injection was made into physiologically defined components of the body representation in SV. After injection of HRP into the(More)
This paper presents an intuitive user interface for a virtual camera controlled by a path and a set of constraints. Here, the constraints mean where an object is to be projected on the screen. In many cases, the camera position plays a more important role than other settings such as the orientation and the field of view angle of the camera. Therefore, in(More)
