[Hypothalamic regulation of retinal function].

Unlabelled: Studying compensatory capacity of the brain is a pressing issue. To resolve it, diversified experiments should be conducted providing an idea of the underlying mechanisms and possibilities of functional restoration.

Aim: To determine the effect of unilateral electrocoagulation of supraoptic (SO) and suprachiasmatic (SCH) hypothalamic nuclei on the appearance of the electroretinogram (ERG).

[Effect of low concentration benzene vapor on metabolism of gamma-aminobutyric acid in brain mitochondrial fractions].

The impact of benzene vapor (0.35 mg/l) of low concentration on the contents of free GABA, Glu and Asp, as well as on the enzyme activities of GDC and GABA-T in mitochondrial fractions of different brain regions of adult male rats was investigated. The conclusion was put forward that GABA increase by means of "keeping" inhibition provided for nerve cells defense from extremal excitation, taking place under the chronic exposure to the benzene low concentration.
