Electrophysiology of the Fetal Spinal
A]BSTRAGT Responses from motoneurons were recorded with microelectrodes, from the spinal cords of kitten fetuses and newborn kittens between 40 days' gestation and a few days after birth. As in the adult animal, intracellularly recorded action potentials by either orthoor antidromic shocks have two components, "A" and "B" or IS and SD. The action potentials of the adult and immature motoneuron ...
متن کاملElectrophysiology of the Fetal Spinal Cord
Interactions of peripheral inputs to the motoneuron of the kitten fetus as young as 3 weeks prenatal were studied by reflex discharge from the ventral root as well as by recording from single motoneurons. Facilitation was found between two synergists in fetuses 1 to 2 weeks before birth. Intracellular recording showed that the facilitation could be explained by summation of excitatory postsynap...
متن کاملElectrophysiology and morphology of the developing hippocampus of fetal rabbits.
The pyramidal neurons of fetal rabbit hippocampus were studied using intracellular electrophysiological techniques in in vitro slice preparations. Correlative light and electron microscopic analyses were carried out on hippocampus during the 21st through the 29th day of fetal gestation. In intracellular experiments, neurons with all-or-none action potentials and near-adult level resting potenti...

متن کاملFetal Atrial Flutter: Electrophysiology and Associations With Rhythms Involving an Accessory Pathway
BACKGROUND Atrial flutter (AFl) accounts for up to one third of all fetal tachyarrhythmias and can result in premature delivery, hydrops, and fetal death in 10% of cases; however, the electrophysiology of AFl in utero is virtually unstudied. METHODS AND RESULTS In this observational study, we reviewed 19 fetal magnetocardiography studies from 16 fetuses: 15 fetuses (21-38 weeks' gestation) re...
