Descripción del proyecto
Aprendizaje asociativo en el pez cebra
La mayoría de las especies relacionan experiencias y estímulos específicos con respuestas, en lo que supone un proceso de aprendizaje necesario que les permita adaptarse y sobrevivir. El proyecto ViCoZe, financiado con fondos europeos, aspira a estudiar en profundidad las dos categorías de este aprendizaje asociativo en el pez cebra. La idea es combinar experimentos conductuales con análisis bioquímicos y neurológicos, así como con la genética, para descubrir las regiones encefálicas, las rutas moleculares y los genes implicados en el aprendizaje. El equipo de ViCoZe proporcionará información fundamental sobre la cognición que puede extrapolarse a los humanos y, además, generará métodos normalizados basados en el pez cebra que puedan utilizarse en futuros estudios en este ámbito.
Objetivo
The ability to learn and memorize information in a constantly changing environment is essential for survival for most species. Two forms of associative learning have been described, elemental and configural, but despite advances in our understanding of their mechanisms, we are still far from having a detailed view of the difference between these two strategies. For the first time, a systematic comparison of elemental and configural learning will be performed in adult zebrafish tested in an automated setup that I previously developed. By pairing the learning experiments with approaches combining pharmacology, neural imagery, biochemistry and genetics, I will aim at identifying brain areas, molecular pathways, especially those involving dopamine and noradrenaline, and genes involved in both forms of learning. Thanks to this project, I will gain invaluable experience from learning new approaches (particularly HPLC, staining and imaging, and RNA sequencing), and improve myself in project management, supervision, and scientific communication; skills required to develop my own independent line of research.
By exploring cognition in zebrafish, a model with a high genetic homology with human and that possess an evolutionarily conserved brain, the results from this project will have a major impact on the advancement of different research areas such as psychology, medicine and evolution of vertebrates. In addition, by giving open access on the automated tank system to the whole zebrafish field, the project will ensure a standardization of the methods in the future and provide a powerful tool for many other topics using zebrafish.
This project is a unique career opportunity, enhancing my understanding of cognition, and expanding my network to the medical and animal welfare community. This will help me to become a recognised expert in animal cognition in different research areas, and to develop a complete and dynamic research group in the future.
