title: Microelectrophoretic application of metabolic modifiers of the phosphofructokinase-hexosediphosphatase-system onto various types of bulbar respiratory neurons.
abstract: Three metabolic modifiers of the PFK-HDPase system were applied to bulbar respiratory neurons and, for comparison, also to unspecific cells. F-6-P did not alter the spike density of the majority of the respiratory and about half of the unspecific neurons. When responding, IE units were activated and unspecific cells were inhibited. Citrate did not alter the spike density of about half of all neurons tested. When responding, excitation prevailed in IE and E units, while unspecific cells were inhibited. AMP did not alter the spike density of the majority of the respiratory and about half of the unspecific cells. When responding, I neurons were activated, inhibition preponderated in IE units and both effects occurred in unspecific cells. The large number of zero effects suggests that the activity of only part of the cells is governed by the PFK-HDPase system.
