Conclusions

Investigation of the electrical activity of different brain structures of the desert monitor (Varanus griseus) in the process of formation and consolidation of defensive CRs gave the following results.
  1. 1.

    In the process of CR formation the electrical activity was modified in all parts of the brain, demonstrating the extensive irradiation of excitation.

     
  2. 2.

    During consolidation of the defensive CRs the changes in electrical activity were mainly limited to the prosencephalon (general and hippocampal cortex).

     
  3. 3.

    Destruction of the anterior hypothalamus led to transient suppression of the slow components of the EEG and to an increase in the amplitude of the fast rhythm. The electrographic CRs were preserved, and in some cases they were actually intensified.

     
  4. 4.

    Massive destruction of the posterior hypothalamus caused an initial depression of both the fast and the slow rhythms of the background electrical activity, followed by the appearance of high-amplitude spindle-shaped waves. The electrographic components of the CR became weaker and disappeared.

     
  5. 5.

    Stimulation of the anterior part of the hypothalamus was accompanied by inhibition of the defensive CR. Stimulation of the posterior hypothalamus evidently stabilized the cortical activity, strengthening it when its functional level was normal or depressing and inhibiting it when its activity was increased.
