For each case, the relative involvement of each MG subdivision in the retrograde tracer deposit is shown on the left, and the relative density of retrogradely-labeled cells in the IC is given on the right. For injection site involvement, a dash indicates no involvement, a single “x” indicates minimal involvement, and an increasing number of “x” symbols indicates increasing involvement of the subdivision. For density of retrograde label, all subdivisions of the IC contained retrogradely-labeled cells in each experiment; however, relative density (average cells per mm2 across 2 sections) is shown with a single asterisk indicating the lowest relative density of label and three asterisks indicating the highest relative density of retrograde label. MGd: dorsal subdivision of the MG; MGm: medial subdivision of the MG; MGsg: suprageniculate subdivisions of the MG; MGv: ventral subdivisions of the MG; ICc: central nucleus of the IC; ICd: dorsal cortex of the IC; IClc: lateral cortex of the IC.
