An analysis of the effects of excitatory amino acid receptor antagonists on evoked field potentials in the olfactory bulb.

abstract：:The tectofugal pathway in birds consists of four stations, the retina, optic tectum, rotundal nucleus, and entopallium, and it conveys visual information via three ascending pathways. These pathways consist of retino-tectal, tecto-rotundal and rotundo-entopallial cells, all of which are glutamatergic. The present stud...
