title: EEG effects of the ventricular cerebrospinal fluid of rabbits submitted to thalamic stimulation.
abstract: Electrical stimulation of the "somnogenic" thalamic area of Hess in chronic rabbit donors significantly increases the EEG delta activity against controls (41%; p less than or equal to 0.05). In recipient rabbits infused with cerebrospinal fluid (csf) from these donors, the delta increase against control rabbits (26%) suggests a sedative activity of the infused csf, able to counteract the waking tendency in chronic recipients.
