Immunization of BALB/c mice with glutamate-BSA conjugate reduced anxiety and improved passive avoidance retention, while in C57Bl/6 mice immunization disturbed passive avoidance retention, but had no effect on anxiety. Interstrain differences in the shuttle box behavior were found between control animals.

The effect of antiserotonin antibodies on basal electrocorticogram was studied in electrophysiological experiments on rats. Intracortical injection of 10 microg antiserotonin antibodies into the sensorimotor cortex induced epileptiform activity in this area. It is assumed that antiserotonin antibodies modulate activity of cortical neurons due to both binding serotonin molecules and interaction with serotonin receptors.

We studied the effects of active immunization with glutamate-protein conjugates on behavioral reactions of C57Bl/6 and BALB/c mice in the open-field test and on animal anxiety in the tail suspension test. Antiglutamate antibodies produced different behavioral changes in mice of these strains.
