A lab made mice that had a mutation in the CREB gene. The scientists then exposed mutant (and control) mice to fear conditioning. What deficit would you expect to see in the CREB mutant mice? (Note: the correct answer here is what the lab actually observed). 

The presence of which gene product inside a neuron is a marker for recent neuronal activation?

In class we discussed the paper, “Optogenetics enables functional analysis of human embryonic stem cell-derived grafts in a Parkinson’s disease model”. In this paper, scientists took hESCs growing in culture and differentiated them into cells that looked like this at 30 days: The scientists then tested these cells for function. One thing they tested (that we did not discuss in class) was that the cells released dopamine when they were stimulated. To do this, the scientists puffed either glutamate (GLU) or saline onto the cells and then measured the amount of dopamine that the cells released into the dish in which they were growing. They did this experiment without optogenetic stimulation (no 545 nm light) and with optogenetic stimulation (in the presence of 545 nm light). You can see the results of this experiment below. (The left side shows the results for the cells that are expressing EYFP, and the right side shows the results for the cells that are also expressing halorhodopsin. Bars outlined in black show results without 545 nm light. Bars outlined in green show results with 545 nm light.) If these cells are functioning as the scientists want: What will the bar look like for cells expressing EYFP that are receiving saline and 545 nm light (bar 1)? Choose from the possible answers. [B] What will the bar look like for cells expressing EYFP that are receiving glutamate and 545 nm light (bar 2)? Choose from the possible answers. [C] What will the bar look like for cells expressing halorhodopsin-EYFP that are receiving glutamate and 545 nm light (bar 3) Choose from the possible answers. [A]
