from a comparison of the distribution of ntir cells with that of cells that can be retrogradely labeled from md or the midline thalamus , the probable source of the ntir fibers to the central part of md is in the deep layer of the piriform cortex , while the ntir fibers to the medial edge of md and the midline nuclei may arise from the preoptic region and the medial amygdala .
