The dorsolateral thalamus as a relay in the retino-wulst pathway in pigeon (Columbia livia). An electrophysiological study.

In 4 dorsolateral thalamic nuclei (LA, DLAmc, DLLd and DLLv) short latency evoked responses were recorded after electrical or photic stimulation of the contralateral eye. Electrical stimulation of these 4 nuclei led to bilaterally evoked responses in the wulst, where previous experiments had demonstrated an oligosynaptic projection from the retina.
