The Time Course And Neuroanatomy Of Rhinophore Regeneration In The Nudibranch Berghia Stephanieae, Ani Maroyan
The Time Course And Neuroanatomy Of Rhinophore Regeneration In The Nudibranch Berghia Stephanieae, Ani Maroyan
Masters Theses
Within five weeks, the nudibranch, Berghia stephanieae (Gastropoda, Mollusca) can regenerate a severed rhinophore, the main olfactory appendage, such that it is indistinguishable from a non-lesioned rhinophore. The rhinophore is a 2 mm long stalk with lateral sides covered in ridges and the distal third covered in fluorescent pigmentation. Its internal morphology is dominated by longitudinal musculature, overlaid by a complex neuronal plexus, which contains neurons that express various neuroactive substances including serotonin and small cardioactive peptide (SCP). Two large nerves originate in the rhinophore ganglion at the base of the rhinophore and run the length of the rhinophore. To …

Development Of A New Behavioral Assay For Juvenile Berghia Stephanieae, Kelly E. Fischer
Masters Theses
Developing robust behavioral assays to study olfactory-driven behaviors allows for greater insight into the neural mechanisms behind them. Oftentimes, olfactory behavioral assays require a two-choice design, consistent variables, and controlled stimulus application. This can be challenging when working with marine dwelling organisms such as nudibranchs. Extensive work shows the importance of olfaction in both pre-metamorphic larval development and adult stage nudibranchs (Gastropoda, Mollusca). However, there is little research investigating how olfaction plays a role in rapidly developing, post-metamorphic juvenile nudibranchs such as Berghia stephanieae. To study olfactory-associated behaviors in juvenile Berghia, a novel behavioral microfluidic chip was designed which …
