Light-evoked changes in chick optic lobe GABA system.
In young chicks the effects of 3 min stroboscope stimulation on GABA and free glutamic acid content and on GAD and GABA-T activity in optic lobes were studied. A significant depletion in GABA and glutamic acid levels was found to occur. In addition a sustained increase in GABA-T and GAD activity was observed. In conclusion present experiments are in favour of an inhibitory role played by GABA in chick optic tectum during stroboscope stimulation.
