Current neuronal cell neuron screening methods are laborious and time consuming, making it a long and difficult process to develop drugs for neurodegenerative diseases. The current methods have the following issues: 

1. Standard 2 – 4 recording sites with the use of the patch-clamp system
2. Low resolution data
3. Drug candidate screening can be susceptible to invalid results due to small sample size.
4. 1 laser is used for single wavelength stimulation

These issues require repetitive experimentation which contributes to the lengthy process in drug development.
