This study presents a comprehensive topographic mapping ofgnrh2,gnrh3,kisspeptin 2 (kiss2),gonadotropin-inhibiting hormone (gnih), andVA opsin using in situ hybridization on mature Atlantic salmon brains. Neurons positive forgnrh3 are expressed in the olfactory bulb and ventral telencephalon, whilegnrh2-positive neurons are located dorsally in the midbrain tegmentum. Gonadotropin-inhibiting hormone (Gnih)-expressing cell bodies are present in the ventral thalamus and extend caudally to the hypothalamus withkiss2-expressing cells appearing in a lateral position.VA opsin-positive cells are present in the telencephalon, the r...

Mapping the pattern of essential neuroendocrine cells related to puberty and VA opsin expression provides further insight in the photoreceptive regulation of the BPG axis in Atlantic salmon (Salmo salar)
This study presents a comprehensive topographic mapping of gnrh2, gnrh3, kisspeptin 2 (kiss2) gonadotrophin inhibiting hormone (gnih) and VA opsin using in situ hybridization on mature Atlantic salmon brains. Neurons positive for gnrh3 are expressed in the olfactory bulb and ventral telencephalon while gnrh2 positive neurons are located dorsally in midbrain tegmentum. Gnih expressing cell bodies are present in the ventral thalamus and extend caudally to the hypothalamus with kiss2 expressing cells appearing in a lateral position. VA opsin positive cells are present in the telencephalon, the rostro-dorsal ring of left haben...

The Everted Amygdala of Ray-Finned Fish: Zebrafish Makes a Case
The amygdala, a complex array of nuclei in the forebrain, controls emotions and emotion-related behaviors in vertebrates. Current research aims to understand the amygdala ’s evolution in ray-finned fish such as zebrafish because of the region’s relevance for social behavior and human psychiatric disorders. Clear-cut molecular definitions of the amygdala and its evolutionary-developmental relationship to the one of mammals are critical for zebrafish models of affe ctive disorders and autism. In this review, I argue that the prosomeric model and a focus on the olfactory system’s organization provide ideal tools for dis...

The neuromeric/prosomeric model in teleost fish neurobiology
The neuromeric/prosomeric model has been rejuvenated by Puelles and Rubenstein (1993). Here, its application to the (teleostean) fish brain is detailed beginning with a historical account. The second part addresses three main issues with particular interest for fish neuroanatomy and looks at the impact of the neuromeric model on their understanding. The first one is the occurence of four early migrating forebrain areas (M1 through M4) in teleosts and their comparative interpretation. The second issue addresses the complex development and neuroanatomy of the teleostean alar and basal hypothalamus. The third topic is the ver...

Comparative neuroanatomy of the mechanosensory subgenual organ complex in the Peruvian stick insect, Oreophoetes peruana
This study documents the same sensory organs for O. peruana, subgenual organ and distal organ, as in other stick insects. Between the sexes of this species, there are no notable differences in the neuroanatomy of their sensory organs. The innervation pattern of tibial nerve branches in O. peruana is identical to other stick insect species, although the innervation pattern of the subgenual organ by a single tibial nerve branch is simpler. The shared organisation of the subgenual organ complex in both groups of Neophasmatodea (Old World and New World stick insects) indicates the sensory importance of the subgenual organ but ...
