Septum after-discharge effects upon cortical photic-evoked responses
In sixteen adult cats, the effects of septum after-discharges on photic evoked responses in the lateral gyrus (primary visual) and the anterior medial suprasylvian gyrus (association) were evaluated. The responses were averaged on a computer of average transients. The early negative components of th...

| description | In sixteen adult cats, the effects of septum after-discharges on photic evoked responses in the lateral gyrus (primary visual) and the anterior medial suprasylvian gyrus (association) were evaluated. The responses were averaged on a computer of average transients.
The early negative components of the responses evoked in the lateral gyrus were attenuated by the after-discharges, but no other consistent effects were observed. No relationship between evoked potential effects and qualities of the after-discharges (duration, propagation, of frequency patterns) could be discerned.
The alteration of sensory input obtained in the present study may explain some of the behavioral impairments observed during psychomotor seizures of limbic origin.
Les auteurs ont étudié sur sieze chats adultes les effets de post-déscharges septales sur les réponses évoquées lumineuses au niveau du gyrus latéral (visuel primaire) et au niveau du gyrus supra-sylvien antériuer médian (d'association). Les réponses sont moyennées par un analyseur d'amplitude (CAT).
Les composantes négatives précoces de la réponses évoquée au niveau du gyrus latéral sont atténuées par les post-décharges, mais aucun autre effet constant n'a été observé. Aucune relation n'a ou être décelée entre les effets des potentiels évoqués et les qualités des postdécharges (durée, propagation ou fréquence).
L'altération de l'afférence sensorielle obtenue dans cette étude peut expliquer certains des troubles comportementaux que l'on peut ontaserver au cours des crises psychomotrices d'origine limbique. |
