Fig. 2From: Unilaterally blocking the muscarinic receptors in the suprachiasmatic nucleus in proestrus rats prevents pre-ovulatory LH secretion and ovulationDiagrammatic representation of the locations of the microinjection sites. a The black circles represent the microinjection sites. Schematic illustration of a coronal section taken from the rat brain atlas of Paxinos and Watson [35]. b Nissl-stained coronal sections illustrating the trajectories of the microneedles into the left SCN. 3 V: third ventricle; OC: optic chiasm; SCN: suprachiasmatic nucleus. The arrowheads indicate the trajectory of the microinjections into the left side of the SCNBack to article page
