Change in number and activation of androgen receptor-immunoreactive cells in the medial amygdala in response to chemosensory input

▶AR-ir was changed in Me by chemostimulation, but not in animals with fixed testosterone levels. ▶AR-ir cells were differentially activated by various chemosignals in Me in intact male hamsters. ▶AR-+ cells were selectively activated by chemosignals at levels above average Fos activation in Me.
