In a month I'll be heading to my alma mater University of Costa Rica to present some of our work on axial specification in annelids 🪱
En un mes estaré presentando nuestro trabajo en especificación de ejes en anélidos en mi alma mater Universidad de Costa Rica
I’m thrilled to share our new publication “Spectro-temporal acoustic elements of music interact in an integrated way to modulate emotional responses in pigs”

Music is a complex stimulus, with various spectro-temporal acoustic elements determining one of the most important attributes of music, the ability to elicit emotions. Effects of various musical acoustic elements on emotions in non-human animals have not been studied with an integrated approach. However, this knowledge is important to design music to provide environmental enrichment for non-human species. Thirty-nine instrumental musical pieces were composed and used to determine effects of various acoustic parameters on emotional responses in farm pigs. Video recordings (n = 50) of pigs in the nursery phase (7–9 week old) were gathered and emotional responses induced by stimuli were evaluated with Qualitative Behavioral Assessment (QBA). Non-parametric statistical models (Generalized Additive Models, Decision Trees, Random Forests, and XGBoost) were applied and compared to evaluate relationships between acoustic parameters and pigs’ observed emotional responses. We concluded that musical structure affected emotional responses of pigs. The valence of modulated emotions depended on integrated and simultaneous interactions of various spectral and temporal structural components of music that can be readily modified. This new knowledge supports design of musical stimuli to be used as environmental enrichment for non-human animals.
Finally back in London after my first trip to Chile 🇨🇱 Learned so much, and so happy to keep making connections with more of the Latin American community at SILPOLY and U de Concepción
