(5) A delayed current decrease associated with prolonged depolarization was studied in R(15) (the parabolic burster) of Aplysia by using intracellular recording and voltage clamp techniques.2.
(6) Cells synaptically driven but not antidromically activated by neural stalk stimulation, which thus probably receive an afferent input from supraoptic neurones, were classified as 'regular' or 'bursters' on the basis of their spontaneous electrical activity.
(7) This current was studied using cell-attached and inside-out patches from the right parietal fast burster neuron of Helix pomatia.
(8) The majority (twelve out of eighteen) of synaptically excited cells (o.d.+) were bursters and the majority of inhibited (o.d.-) cells (eleven out of nineteen) were regular, but only one o.d.+ burster showed any change of activity (inhibition) before milk ejection.
(9) They show different steady-state I-V curves under simulated voltage-clamp conditions; in simulations that mimic a steady-state I-V curve taken under experimental conditions only Burster N shows a negative slope resistance region.
(10) Our results indicate that CAN currents in Helix burster neurones are modulated by cyclic AMP-dependent membrane phosphorylation.
(11) Our results suggest that in the cat, for saccades of amplitude smaller than 20 deg, there is a variable degree of suppression which is provided by a projection of excitatory bursters (EBNs) on second-order vestibular neurones through inhibitory type II neurones.
(12) with three basic patterns of spontaneous activity: ;silent' cells (s., four cells, 3%); ;low-frequency burster' cells (l.f.b., twenty-six cells, 21%); and ;continuously active' cells (c.a., seventy-nine cells, 63%).6.
(13) Voltage clamp studies reveal that halothane will eliminate the slow inward current that underlies oscillatory activity in burster neurons, while high pressure shifts the negative resistance region of the current without causing its elimination.
(14) Of the thirty-two repetitive bursters, twenty-four received no apparent patterned synaptic input and the phasic burst behaviour was voltage dependent.
(15) IA was largest in pyloric dilator (PD) and PY cells, smaller in the anterior burster (AB), LP, and inferior cardiac (IC) cells, and undetectable in the VD cell.
(16) Based on the hypothesis that bursting activity of RPa1 neuron results from the activation of presynaptic unidentified peptidergic interneuron(s) with persistent activity and on data presented it is suggested that inhibition of bursting activity evoked by application of dopamine or anal nerve stimulation is a consequence of decreased efficiency of synaptic transmission between the interneuron initiating bursting activity and the burster.
(17) It consists of two (protractor and retractor) groups of neurons with mutual inhibitory connections, neurons of each group being endogenous bursters.
(18) These neurones, like burster-driving neurones described in paralysed cats, were characterized by a tonic increase of firing for head turning in the contraversive direction (type II) associated to bursts for each vestibular quick phase in the same direction.
(19) Burster neurons seem to play a special role in this mechanism.
(20) We prove that an asymmetry between the uncoupled bursters can accelerate the system with respect to the free cells, this effect depending on the characteristics of the coupling.
