Practical and effective light delivery during behavioral modulation is a key challenge in applying optogenetics to understand ... light to the surface of the mouse brain with an LED.

Nestler, Deisseroth and company have now essentially used optogenetics to replicate Mayberg's work in mice, and it seems to have worked. Their target — a particular area in the mouse's ventral ...

have succeeded for the first time in controlling the function of sperm by optogenetics. They inserted a light-activated enzyme for cAMP synthesis into mouse sperm that lacked the endogenous enzyme.

Seven years prior, Deisseroth and his colleagues demonstrated the ability to activate individual neurons in live and alert mice. This recent study represents a leap forward in optogenetics.

The scientists put this new technology to work in experiments where the mice were able to look and behave like normal, enabling them to conduct the first optogenetics study of social interactions ...

In optogenetics, you use light to turn on or turn off certain neurons. The researchers stimulated the neurons of four mice to make them produce more dopamine, and blocked the neurons of four mice ...

But when, for instance, the neurons that had fired in response to a vertical bar were stimulated with optogenetics, the mice were better able to correctly make out the hazy image of the vertical bar.

They inserted a light-activated enzyme for cAMP synthesis into mouse sperm that lacked the ... as fundamental as fertilisation with light. Optogenetics has thus conquered another field outside ...
