Laboratory for Circuit Mechanisms of Sensory Perception, Center for Brain Science (Laboratory head：Hokto Kazama)
Animals decide and act based on past and current sensory information. The major goal of our lab is to mechanistically understand how neural processing of external input guides behavior and how this processing is modulated depending on the environmental and behavioral contexts.
To achieve this goal, we are using the fruit fly Drosophila melanogaster, which has been increasingly recognized as one of the ideal organisms for investigating the neural circuit basis of behavior. Due to the relatively small number of central neurons, many neurons in the fly brain are identifiable and accessible. We can monitor the responses of these neurons to sensory stimuli by in vivo electrophysiology and imaging. Various genetic tools are available for not only labeling but also manipulating neurons. On the other hand, technologies have been developed to monitor individual flies behaving in a virtual environment where external stimuli can be precisely controlled online. With these data in hand, we will utilize quantitative modeling approaches to better understand the computation and the neural mechanisms underlying behavior at cellular, synaptic and circuit levels.

In principle, the first two months of employment is considered a trial period.
Salary will be commensurate with qualifications and experience. Discretionary work, commuting and housing allowances will be provided. Social insurance will be applied. Mandatory membership in the RIKEN Mutual Benefit Society (RIKEN Kyosaikai).
This position falls under the specialized duties discretionary work system; one working day will be calculated as 7 hours and 30 minutes.
Days off include public holidays, New Year's holidays (Dec. 29 - Jan 3), and RIKEN Foundation Day.
Paid leave includes annual paid leave (up to 20 days depending on the month of employment), special paid leave (childcare, family nursing care, etc.), and work life balance holidays (up to 7 days depending on the month of employment).
There are also additional leave systems such as maternity leave, childcare leave, and family nursing care leave.
RIKEN has introduced telework as a temporary and special measure to prevent the spread of COVID-19. You may be asked to work from home according to the instructions of the institute. You can also choose to work from home with the permission of your supervisor.
No smoking on site (designated smoking areas available).
These and other provisions are in accordance with RIKEN regulations.
RIKEN is actively undertaking initiatives to promote Gender Equity Program, and moving forward with the establishment of a diverse and vibrant research environment. If multiple candidates are found to have the same aptitude following a fair assessment, active efforts will be made to recruit female candidates.
