Stereotyped modulations of EOD frequency and amplitude are common in social situations and are thought to serve as communication signals Brown ghosts, Apteronotus leptorhynchus, are weakly electric gymnotiform fish whose wave-like electric organ discharges are distinguished by their enormous degree of regularity.Despite this constancy, two major types of transient electric organ discharge modulations occur: gradual frequency rises, which are characterized by a relatively fast increase in electric organ discharge frequency and a.

In this video I'm talking about the Brown Ghost Knife fish (Apteronotus leptorhynchus), and general care and info on this species. If you have any questions. L' Apteronotus albifrons appartiene alla Famiglia degli Apteronotidae (Ghost knifefish, pesci coltello fantasma), dell'Ordine dei Gymnotiformes ed è comunemente chiamato pesce coltello, o pesce coltello fantasma, in inglese Black ghost, I nativi sudamericani credono che i fantasmi dei defunti si stabiliscano in questi pesci, da cui il nome Apteronotus leptorhynchus Holotype: FMNH 53294 [ex CM 1762, not 1763a]. Paratypes: CAS 62333 [ex IU 12588] (1); FMNH 53295 (1) [? ex CM 1764a]
Members of Apteronotus fall into three species groups based on their morphology: the A. albifrons group have a rounded snout and are black or dark brown with a contrasting light stripe on the top of the head, and bands on the tail and at its base, the A. leptorhynchus group have an elongate, slender snout (especially in males) and are brown with a light stripe along the head and back, and a band on the tail, and the A. bonapartii group have an elongate (males) or rounded (females.

In Apteronotus leptorhynchus, the mean EOD frequency of males is approximately 880 Hz, whereas the mean frequency of females is significantly lower, around 740 Hz (Zupanc et al., 2014). Implantation with β-estradiol results in a gradual decrease of the EOD frequency in both males and females ( Fig. 5 ) ( Meyer et al., 1987 ; Schaefer and Zakon, 1996 ; Zupanc et al., 2014 ) ﬁsh Apteronotus leptorhynchus. We describe here some molecular properties of the NR1 subunit of the N-methyl-D-aspartate (NMDA) class of postsynaptic glutamate receptors in this system and compare these with the properties of the mammalian NR1 subunit. Studies of mammalian neurons have shown that postsynaptic membranes contain a variety of.

Cellular mechanisms underlying regeneration of the spinal cord in Apteronotus leptorhynchus by Antonia G. Vitalo B.S. in Biology, Quinnipiac University A dissertation submitted to The Faculty of the College of Science of Northeastern University in partial fulfillment of the requirements for the degree of Doctor of Philosophy November 29, 201 We present high temporal and spatial resolution maps in 3-dimensions of the electric field vector generated by the weakly electric fish, Apteronotus leptorhynchus. The waveforms and harmonic composition of the electric organ discharge (EOD) are variable around the fish but highly stable over long times at any position lower than values reported in the closely related species Apteronotus leptorhynchus and the more distantly related species Eigenmannia virescens. In response to stimuli with time-varying amplitude (i.e., envelope), ON- and OFF-type cells displayed similar high-pass tuning curves characteristic of fractional differentiation and possibly indicat and neurogenesis in weakly electric fish, Apteronotus leptorhynchus. In highly gregarious animals, the presence of conspecifics ameliorates the neural or behavioral responses to a perceived threat― a phenomenon termed social buffering (Kiyokawa, 2018; Kikusui et al., 2006). In 1955, Davitz and Mason first proposed a socia weakly electric fish, Apteronotus leptorhynchus.Weper-formed multi-channel recordings in the electrosensory lat-eral line lobe, which benefits from well-characterized neural architecture. First, a spike-sorting algorithm was applied on the recorded signals to extract neural units. Then, correlated activity can be examined from pairwis

Information about genome files, completeness, GC-content, size, N50-values, and sequencing methods are listed By contrast, regeneration-competent organisms, such as teleost fish, are capable of successful adult neurogenesis. Research in this dissertation examines factors which contribute to the successful regeneration of the spinal cord in the teleost fish Apteronotus leptorhynchus Maintaining a stable social organization necessitates that animals recognize their own dominance status relative to that of other conspecifics.
