[Hypothalamic projections into the midbrain reticular formation and the parafascicular complex in the cat detected by means of retrograde horseradish peroxidase transport].

By the method of horseradish peroxidase (HP) retrograde transport (the injection was performed into the thalamic parafascicular complex in 7 cats) connections between the hypothalamus, the midbrain reticular formation and the parafascicular complex were followed. Other connections of the hypothalamus with some cerebral centers were also discussed.
