The communication behaviors of vocal fish and electric are among the vertebrate social best understood at level neural circuits. Both forms signaling rely on midbrain inputs to hindbrain pattern generators that activate peripheral effectors (sonic muscles electrocytes) produce pulsatile signals modulated by frequency/repetition rate, amplitude call duration. To generate vary sex, male phenotype, context, these circuits responsive a wide range hormones neuromodulators acting different timescales multiple loci. Bass Zakon (2005) reviewed behavioral neuroendocrinology two teleost groups, comparing how regulation their systems have both converged diverged during parallel evolution. Here, we revisit this comparison review complementary developments over past 16 years.

The senses of hearing and balance are subject to modulation by efferent signaling, including the release dopamine (DA). How DA influences activity auditory vestibular systems its site action not well understood. Here we show that dopaminergic fibers innervate acousticolateralis epithelium zebrafish during development but do directly form synapses with hair cells. However, a member D1-like receptor family, D1b, tightly localizes ribbon in inner ear lateral-line To assess hair-cell activity, reversibly activated or inhibited receptors (D1Rs) In extracellular recordings from cells, observed D1R agonist SKF-38393 increased microphonic potentials, whereas antagonist SCH-23390 decreased potentials. Using ratiometric calcium imaging, found resulted larger transients increase intracellular requires Cav1.3a channels, as Cav1 channel antagonist, isradipine, blocked elicited SKF-38393. Collectively, our results suggest is released paracrine fashion acts at synapses, likely enhancing presynaptic channels thereby increasing neurotransmission.

The response of sensory neurons to stimuli can be modulated by a variety factors including attention, emotion, behavioral context, and disorders involving neuromodulatory systems. For example, patients with Parkinson's disease have disordered speech processing, suggesting that dopamine alters normal representation these salient sounds. Understanding the mechanisms which modulates auditory processing is thus an important goal. principal midbrain nucleus, inferior colliculus (IC), likely location for dopaminergic modulation because it contains receptors nerve terminals immunoreactive tyrosine hydroxylase (TH), rate-limiting enzyme in synthesis. However, sources input IC are unknown. In this study, we iontophoretically injected retrograde tracer into mice then stained tissue TH. We also immunostained beta-hydroxylase (DBH), critical conversion norepinephrine, differentiate between noradrenergic inputs. Retrogradely labeled were positive TH seen bilaterally, strong ipsilateral dominance, subparafascicular thalamic nucleus (SPF). All retrogradely observed other brain regions TH-negative. Projections from SPF confirmed using anterograde tracer, revealing TH-positive DBH-negative anterogradely fibers IC. While functional role not yet known, provides potential mechanism context dependent processing.

Abstract Vocalizations communicate information indicative of behavioural state across divergent social contexts. Yet, how brain regions actively pattern the acoustic features context-specific vocal signals remains largely unexplored. The midbrain periaqueductal gray (PAG) is a major site for initiating vocalization among mammals, including primates. We show that PAG neurons in highly fish species ( Porichthys notatus ) are activated distinct patterns during agonistic versus courtship calling by males, with few co-activated non-vocal behaviour, foraging. Pharmacological manipulations within vocally active PAG, but not hindbrain, sites evoke network output to sonic muscles matching temporal and calls, showing balance inhibitory excitatory dynamics likely necessary patterning different call types. Collectively, these findings support hypothesis mammals share functionally comparable nodes some can influence structure signals.

Vocalization is a prominent social behavior among vertebrates, including in the midshipman fish, an established model for elucidating neural basis of acoustic communication. Courtship vocalizations produced by territorial males are essential reproductive success, vary over daily and seasonal cycles, last up to hours per call. Vocalizations rely upon extreme synchrony millisecond precision firing homogeneous population motoneurons, vocal motor nucleus (VMN). Although studies have identified mechanisms driving rapid, precise, stable neuronal long periods calling, little known about underlying genetic/molecular mechanisms.We used RNA sequencing-based transcriptome analyses compare patterns gene expression VMN surrounding hindbrain across three time points high low sound production identify candidate genes that underlie VMN's intrinsic network properties. Results from ontology enrichment, enzyme pathway mapping, category-wide levels highlighted importance cellular respiration function, consistent with energetic demands sustained behavior. Functionally important upregulated VMN, at corresponding natural activity, encode ion channels neurotransmitter receptors, hormone receptors biosynthetic enzymes, neuromodulators, aerobic antioxidants. Quantitative PCR RNA-seq 28 were significantly correlated. Many products regulate excitability, those previously as well novel ones remain be investigated. Supporting evidence previous strongly validate value transcriptomic linking characters drive behavior.Transcriptome suite molecular vocalization behaviorally relevant timescales, spanning milliseconds seasons. To our knowledge, this first comprehensive characterization dedicated nucleus. Candidate here may belong conserved genetic toolkit motoneurons facing similar neurophysiological demands.

Dopaminergic neurons of the descending diencephalospinal system are located in posterior tuberculum zebrafish (Danio rerio), and correspond mammals to A11 group hypothalamus thalamus. In larval zebrafish, they likely only source central dopaminergic projections periphery. Here, we characterized tubercular fibers projecting peripheral sense organs, with a focus on lateral line neuromasts. We labelled identified catecholaminergic their by combining two immunofluorescence techniques, (i) using an antibody against Tyrosine hydroxylase, (ii) GFP transgenic expressing either membrane-anchored track fibers, or Synaptophysin-GFP fusion visualize putative synapses. applied CLARITY method six days old whole larvae stain analyze confocal microscopy. found that all neuromasts receive direct innervation neurons, tracked these detail. addition, anterior ganglia, extensive arborizations around terminal projection field afferent hindbrain medial octavolateralis nucleus.
