Attention and Motivated Response to Simulated Male Advertisement Call Activates Forebrain Dopaminergic and Social Decision-Making Network Nuclei in Female Midshipman Fish

Little is known regarding the coordination of audition with decision-making and subsequent motor responses that initiate social behavior including mate localization during courtship. Using midshipman fish model, we tested hypothesis time spent by females attending responding to advertisement call correlated activation a specific subset catecholaminergic (CA) network (SDM) nuclei underlying auditory- driven sexual motivation. In addition, quantified relationship neural between CA SDM in all responders goal providing map functional connectivity circuitry motivated state responsive acoustic cues localization. order make baseline qualitative comparison this brain unmotivated females, made similar correlative who were unresponsive playback. Our results support an important role for dopaminergic neurons periventricular posterior tuberculum ventral thalamus, putative A11 A13 tetrapod homologues, respectively, as well parvocellular preoptic area dorsomedial telencephalon, (laterobasal amygdala homologue) auditory attention appetitive fishes. These findings may also offer insights into function these highly conserved context auditory-driven reproductive across vertebrates.

Dopamine injections to the midbrain periaqueductal gray inhibit vocal-motor production in a teleost fish

Physiology & Behavior, Journal Year: 2023, Volume and Issue: 263, P. 114131 - 114131

Published: Feb. 14, 2023

Across vertebrates, the midbrain periaqueductal gray (PAG) plays a critical role in social and vocal behavior. Dopaminergic neurotransmission also modulates these behaviors, dopaminergic innervation of PAG has been well documented. Nonetheless, potential dopamine shaping production at level is not understood. Here, we tested hypothesis that PAG, using well-characterized vertebrate model system for study communication, plainfin midshipman fish, Porichthys notatus. We found focal injections to rapidly reversibly inhibited triggered by stimulation known vocal-motor structures preoptic area / anterior hypothalamus. While output, it did alter behaviorally-relevant parameters this such as vocalization duration frequency. Dopamine-induced inhibition was prevented combined blockade D1- D2-like receptors but unaffected isolated either D1-receptors or D2-receptors. Our results suggest neuromodulation may inhibit natural behavior, courtship and/or agonistic contexts.

Brain Activation Patterns in Response to Conspecific and Heterospecific Social Acoustic Signals in Female Plainfin Midshipman Fish, <b><i>Porichthys notatus</i></b>

While the peripheral auditory system of fish has been well studied, less is known about how fish’s brain and central process complex social acoustic signals. The plainfin midshipman fish, <i>Porichthys notatus</i>, become a good species for investigating neural basis communication because production reception signals paramount this species’ reproductive success. Nesting males produce long-duration advertisement calls that females detect localize among noise in intertidal zone to successfully find mates spawn. How female are able discriminate male from environmental other stimuli unknown. Using immediate early gene product cFos as marker activity, we quantified activation ascending pathway exposed conspecific calls, heterospecific white seabass or ambient environment noise. We hypothesized hindbrain nuclei would be activated by general (ambient biotic stimuli) whereas neurons midbrain forebrain selectively calls. show two regions hindbrain, i.e., rostral intermediate division descending octaval nucleus ventral secondary nucleus, did not differ via immunoreactive (cFos-ir) activity when different stimuli.

Sexual dimorphism in the hypophysiotropic tyrosine hydroxylase-positive neurons in the preoptic area of the teleost, Clarias batrachus

Biology of Sex Differences, Journal Year: 2015, Volume and Issue: 6(1)

Published: Nov. 9, 2015

Dopamine (DA) neurons in the anteroventral periventricular nucleus (AVPV) preoptic area (POA) of mammals express estrogen receptors, regulate luteinizing hormone (LH) secretion, and show distinct sexual dimorphism. In teleosts, hypophysiotropic DA preopticus periventricularis (NPP), located POA, innervate LH cells, emerged as a neuroanatomical substrate for inhibiting cells. Interestingly, NPP AVPV seem to share several similarities. Whether DAergic dimorphism is, however, not known. Based on proposed homology previous studies showing greater tyrosine hydroxylase (TH) mRNA enzyme activity levels brain female catfish, we hypothesize that females have number correspondingly more TH-immunoreactive fiber innervation pituitary. Adult, male Clarias batrachus collected during prespawning phase their reproductive cycle were used.

Teleost fishes have evolved a number of sound-producing mechanisms, including vibrations the swim bladder. In addition to sound production, bladder also aids in reception. While production and reception by has been described separately fishes, extent which it operates for both single species is unknown. Here, using morphological, electrophysiological modelling approaches, we show that male plainfin midshipman fish (
