| Abstract(in English) | Two-dimensional neuronal networks were formed using a dissociated culture of rat hippocampal neurons on glass plates. Neural activity in response to pulse stimuli applied to the neurons by whole-cell clamp electrodes was observed with a 128-channel optical recording apparatus using a voltage-sensitive dye, RH482. Dendrites emerging from the somata of single neurons were classified according to two signal-transmission properties, those with action potentials and those with electrotonic potentials, by evaluating the conduction velocities of pulse responses. The distinction between these two properties seemed to be related to the morphological differences in input connectivity with the axons of neighboring neurons. Recursive neural responses were also observed in neuronal circuits involved in two-neuron systems. |
