Petersen et al. 2013 ). Individual DA neurons in TPp may not only project to the
saccule and hindbrain auditory nuclei, but also send ascending projections to the
ventral telencephalon (i.e., Vd, Vv; see Rink and Wullimann 2001 , 2002 ; Tay et al.
2011 ), and are therefore in a perfect position to affect primary auditory processing
and higher brain function involved in behavioral decision making to salient auditory
cues (Fig. 6 A; Goodson and Kingsbury 2013 ; O’Connell and Hofmann 2011 , 2012 ;
Petersen et al. 2013 ).
Fig. 13 cFos-ir colocalization with catecholaminergic (TH-ir) neurons. Arrowheads indicate
cFos-ir colocalized to catecholaminergic neurons within the dopaminergic periventricular posterior tuberculum (TPp) ( a , b ) and the noradrenergic locus coeruleus (LC) ( d , e ) of males exposed to
social acoustic signals and males exposed to ambient noise. Data in c and f are represented as mean
percent colocalization ± SE, ** p ≤ 0.01, *** p < 0.001. Scale bar = 100 μm. Arrows represent the
dorsal (D) and lateral (L) orientation for each image. From Petersen et al. ( 2013 )
