Spike activity of single perigeniculate (PGN) neurons was recorded in the anaesthetized (N2O/halothane) and paralysed cat during presentation of moving gratings of optimal spatial frequency. Typically, the ongoing (tonic, spontaneous) activity of PGN cells increased during a rise in EEG delta power accompanied by a reduction and often a total loss of spike rate modulation by the moving grating. The opposite behaviour was found when the EEG delta power vanished. Micro-iontophoretically applied acetylcholine (ACh) had an effect similar to a decrease in EEG delta power, decreasing ongoing activity but increasing the response modulation depth. The opposite effect could be achieved with the excitatory action of serotonin (5-HT), mimicking a strengthened EEG delta power. These data support previous data indicating that PGN neurons contribute to spatio-temporal tuning of subcortical visual activity in a state-dependent way.
