Catecholaminergic Innervation of Central and Peripheral Auditory Circuitry Varies with Reproductive State in Female Midshipman Fish, Porichthys notatus
Fig 8
Seasonal differences in dopaminergic neuron number in the forebrain.
(A, B) Clusters of small TH-ir cells (arrowheads) located in the lateral region of the anterior parvocellular preoptic nucleus (PPa). (D, E) Sparse numbers of TH-ir cells (arrowheads) in the anterior tuberal hypothalamus (AT). Data in C and D are expressed as number of TH-ir neurons per section (mean ± SE). Mean number of neurons per section for animal in A = 14; B = 32; D = 0; E = 0.6. **p = 0.001. Scale bar = 100 μm.
