  • Title: Analysis and modulation of spike trains and oscillations in identified neural network of Lymnaea stagnalis L.
    Author: Molnár G, Szücs A, Rózsa KS.
    Journal: Acta Biol Hung; 2000; 51(2-4):231-5. PubMed ID: 11034147.
    Abstract:
    Identified neurons and members of functionally characterized clusters of the central nervous system of Lymnaea stagnalis L. were studied. Long-term spike trains (10-100 min) were collected using current clamp method. Firing patterns were analyzed by several mathematical tools e.g.: spike density function (SDF), interspike interval (ISI), Fourier-transform. Both the spike trains and oscillation of firing were modulated by 5HT (2 x 10(-5) M) and mu-opioid peptides (10(-5) M). Co-application of 5HT (2 x 10(-5) M) and DAGO (10(-5) M) turned the firing of the neurons (RPeD1 and A cells) opposite to the running pattern and eliminated the 0.3 Hz oscillation causing a new slow periodicity (0.1-0.05 Hz).
