Feelings of delight associated with the brain’s reward circuits are generally linked to dopamine (DA), a well-known reward chemical and neurotransmitter. But aside from DA’s famous role as the “happy hormone,” it’s also involved in reinforcement learning, decision making, and motor control. 

As part of our partnership with the Penn Vector Core, we will be expanding our inventory of tools for calcium sensing. In this post, we’ll review the main categories of sensors we’ll have available.

In a previous blog post we discussed how fluorescent proteins can be used to construct biosensors, biological tools that monitor processes or detect molecules. Here we’ll be diving into the details surrounding SF-iGluSnFr, a recently upgraded biosensor designed to detect glutamate.
