Laboratory for neural circuit of multisensory integration RIKEN Hakubi team, Center for Brain Science (Laboratory head:Asuka Takeishi)

Research Area

Biology, Interdisciplinary


Neuroscience, behavior, imaging, modeling, molecular biology, C.elegans

Research Field

We are interested in how animals make behavioral decisions. Animals are exposed to continuously changing environmental stimuli, such as temperature, odor, light and sound. We sense and integrate these environmental cues in the nervous system in order to choose appropriate behavioral responses. We are currently investigating the mechanism of multi-sensory integration in the nervous system by analyzing behavior strategies and neural circuits of C. elegans that are exposed to multiple stimuli, especially temperature and odor. In addition to this biological approach, we incorporate mathematical and computational models to reveal the evolutionally-conserved fundamental mechanism of behavioral decision

Job title and job description

Research Scientist 2 positions

Job description

We use C.elegans and take approaches of behavior analysis (thermotaxis and chemotaxis), in vivo calcium imaging, molecular biology and genetics to understand the neural and molecular mechanism of behavioral decisions. We are looking for highly motivated researchers who have abilities to conduct experiments, analysis and build a good relationship in a team. Skills in bioinformatics and/or mathematical modeling would be an advantage. Experience using C.elegans is not essential.


Doctoral degree (or equivalent research ability and background) in the relevant field.
