“…The amphibian POA has several subregions based on cell size (Northcutt and Kicliter, 1980), although the homology of these subpopulations to the mammalian POA is uncertain. Functionally, the POA plays a conserved role in the regulation of sexual behavior in both male and female amphibians.…”

All animals evaluate the salience of external stimuli and integrate them with internal physiological information into adaptive behavior. Natural and sexual selection impinge on these processes, yet our understanding of behavioral decision-making mechanisms and their evolution is still very limited. Insights from mammals indicate that two neural circuits are of crucial importance in this context: the social behavior network and the mesolimbic reward system. Here we review evidence from neurochemical, tract-tracing, developmental, and functional lesion/stimulation studies that delineates homology relationships for most of the nodes of these two circuits across the five major vertebrate lineages: mammals, birds, reptiles, amphibians, and teleost fish. We provide for the first time a comprehensive comparative analysis of the two neural circuits and conclude that they were already present in early vertebrates. We also propose that these circuits form a larger social decision-making (SDM) network that regulates adaptive behavior. Our synthesis thus provides an important foundation for understanding the evolution of the neural mechanisms underlying reward processing and behavioral regulation. J. Comp.

INDEXING TERMS: social behavior; comparative neuroanatomy; amphibian; reptile; bird; teleost; reward system; social behavior network; limbic system; neural circuitsThroughout their lives, all animals constantly face situations that provide either challenges (e.g., aggression, predation) or opportunities (e.g., reproduction, foraging, habitat selection) (for a detailed review, see O'Connell and Hofmann, 2011). In all cases, environmental cues are processed by sensory systems into a meaningful biological signal while internal physiological cues (e.g., condition, maturity) and prior experience are integrated at the same time. This process usually results in behavioral actions that are adaptive, i.e., beneficial to the animal. To accomplish this, an animal's nervous system must evaluate the salience of a stimulus and elicit a context-appropriate behavioral response. Despite tremendous progress in understanding the ecology and evolution of social behavior (Lorenz, 1952;Tinbergen, 1963;Lehrman, 1965;von Frisch, 1967;Krebs and Davies, 1993;Stephens, 2008), it is less understood where in the brain these decisions (e.g., about mate choice or territory defense) are made and how these brain circuits have arisen over the course of vertebrate evolution.Recent research has begun to decipher the neural basis of social decision-making. In mammals in particular, the neural circuits that evaluate stimulus salience and/or regulate social behavior have been uncovered to some degree: the mesolimbic reward system and social behavior network (Fig. 1). It is becoming increasingly clear that the reward system (including but not limited to the midbrain dopaminergic system) is the neural circuit where the salience of an external stimulus is evaluated (Deco and Rolls, 2005;Wickens et al., 2007), as appetitive beh...

The neurohypophysial nonapeptides vasotocin (VT) and mesotocin (MT) are the amphibian counterparts of arginine vasopressin (AVP) and oxytocin (OT). We have here reported the cloning and functional characterization of the receptors for vasotocin (VTR) and mesotocin (MTR) in two species of frog, Rana catesbeiana and Rana esculenta. The frog VTR and MTR cDNAs encode proteins of 419 and 384 amino acids respectively. Frog VTR exhibits a high degree of sequence identity with the mammalian AVP-1a (V1a) receptor while the frog MTR possesses a high degree of sequence identity with the mammalian OT receptor. Activation of VTR induced both c-fos promoter-and cAMP-responsive element (CRE)-driven transcriptional activities, while activation of MTR induced c-fos promoter-driven transcriptional activity but failed to evoke CRE-driven transcriptional activity, suggesting differential G protein coupling between VTR and MTR. The VTR exhibited the highest sensitivity for VT followed by OT.AVP

“…Así, el telencéfalo de los anfibios puede dividirse en una región palial (palio o pallium) y otra subpalial (Muzio, 1999(Muzio, , 2013Rodríguez et al, 1998). En el palio de los anfibios pueden distinguirse tres zonas principales: (1) el pallium medial, considerado homólogo a la formación hipocampal de los ma míferos, que es la región más extensa del palio y ocupa el cuadrante dorsomedial del hemisferio, (2) el pallium dorsal, que puede considerarse homólogo al isocortex de otros vertebrados y se continúa lateralmente con el pallium medial, sin que se aprecie una frontera precisa entre ambas zonas y (3) el pallium lateral, que es considerado homólogo al córtex piriforme de otros vertebrados y ocupa el cuadrante dorsolateral del hemisferio (Muzio, 2013;Northcutt & Kicliter, 1980). La hipótesis muy aceptada respecto de que el pallium medial de los anuros es homólogo al complejo hipocampal de otros tetrápodos, está basada en su posición topográfica (cuadrante dorsomedial telencefálico), derivada de un desarrollo cerebral por evaginación (Pa pini, Salas & Muzio, 1999), y de sus interconexiones neurales con otras áreas telencefálicas, así como de datos histoquímicos (Northcutt & Ronan, 1992).…”
