Optogenetics has become a key tool for understanding the function of neural
circuits and controlling their behavior. An array of directly light driven opsins
have been genetically isolated from several families of organisms, with a wide
range of temporal and spectral properties. In order to characterize, understand
and apply these opsins, we present an integrated suite of open-source,
multi-scale computational tools called PyRhO. The purpose of developing PyRhO is
three-fold: (i) to characterize new (and existing) opsins by automatically
fitting a minimal set of experimental data to three-, four-, or six-state kinetic
models, (ii) to simulate these models at the channel, neuron and network levels,
and (iii) provide functional insights through model selection and virtual
experiments in silico. The module is written in Python with an additional
IPython/Jupyter notebook based GUI, allowing models to be fit, simulations to be
run and results to be shared through simply interacting with a webpage. The
seamless integration of model fitting algorithms with simulation environments
(including NEURON and Brian2) for these virtual opsins will enable
neuroscientists to gain a comprehensive understanding of their behavior and
rapidly identify the most suitable variant for application in a particular
biological system. This process may thereby guide not only experimental design
and opsin choice but also alterations of the opsin genetic code in a
neuro-engineering feed-back loop. In this way, we expect PyRhO will help to
significantly advance optogenetics as a tool for transforming biological
sciences.
