[Spatio-temporal study of the electrical activities of the olfactory bulb of the trout Salmo gairdneri].

The electrical stimulation of the olfactory nerve allows to record steady field potentials in the olfactory bulb of the trout Salmo gairdneri. 200 microns separate recording points which are localised on a tridimensional network. At 18, 24, 30 and 38 ms the amplitudes are measured and plotted in a calculator which determines the isopotentials in any vertical, horizontal and sagittal planes. With this method, we have an instantaneous and global vision of bulbar activity and we observe striking anatomo-functional correlations in the olfactory bulb of Salmo gairdneri.

[Relationship between the incremental and behavioral responses evoked by stimulation of the ventral anterior nucleus of the rat thalamus].

Low frequency stimulation of nucleus Ventralis Anterior thalami in unanesthetized rats elicits incremental responses and produces, in some conditions, characteristic behavioral reaction. Stimulation thresholds giving rise to behavioral reaction are higher than those allowing to find electrocortical responses. The analysis of their evolution discloses changes which are bound to both of the following parameters: the stimulation frequency and the arousal. The lowest behavioral thresholds are got at 8-10 c/s during relaxed wakefulness whereas the lowest electrocortical thresholds are found at 5-8 c/s during slow-wave sleep.
