1. Monoplar tungsten micro-electrodes were used to stimulate and platinun plated tungsten micro-electrodes to record from single, unmyelinated cerebellar parallel fibres and lateral Lissauer tract axons in cats. 2. Stimulation of the lateral Lissauer tract resulted in the activation of a narrow, longitudinal 'beam', much as on the cerebellar surface. 3.(More)
Axonal projections of eighty-four rostral medullary expiratory neurones of the Bötzinger complex were tested using antidromic mapping techniques in anaesthetized cats. A projection to the ventral respiratory neurones of the medulla (n.r.a.) was shown in eleven out of twelve tested neurones. Also a spinal projection to the C5-C6 cervical segments was evident(More)
To make full use of research data, the bioscience community needs to adopt technologies and reward mechanisms that support interoperability and promote the growth of an open 'data commoning' culture. Here we describe the prerequisites for data commoning and present an established and growing ecosystem of solutions using the shared(More)
Synaptic connections of the medullary inspiratory neurones of the nucleus tractus solitarius (NTS) and nucleus retroambigualis (NRA) with phrenic motoneurones were studied using spike triggered averaging of the synaptic noise of phrenic motoneurones. More than 60% of NTS inspiratory neurones made monosynaptic connections with phrenic motoneurones, while(More)
Respiratory neurones from retrofacial (NRF) and Bötzinger nuclei (BOT) were tested electrophysiologically for projection to the contralateral inspiratory region of the nucleus of the tractus solitarius (NTS). Antidromic activation was demonstrated for 30 expiratory neurons (out of a mixed population of 61). There was evidence of extensive branching within(More)
A specialized type of spinal cord cell has its cell body in lamina IV and has a small low threshold cutaneous receptive field which is remarkable for its abrupt edge. No signs could be found of a subliminal fringe to this field since its size remains fixed during wide excursions of the cell's excitability. Reversible blocking of peripheral nerves and dorsal(More)
Synaptic connections between medullary expiratory neurons and phrenic motoneurons were studied in anesthetized cats using spike-triggered averaging of synaptic noise in phrenic motoneurons. Monosynaptic inhibition of phrenic motoneurons originating from the rostral medullary expiratory neurons of the Bötzinger complex was revealed. Neither mono- nor(More)
