What is a correct interpretation when using calcium imaging to measure olfactory receptor response?

a) the more strongly the orn is activated, the more the fluorescence increases.
b) the more strongly the orn is activated, the more the fluorescence decreases.
c) the more strongly the orn is activated, the greater the "glow".
d) the more strongly the orn is activated, the more the concentration of calcium ions.

The more strongly the ORN is activated, the fluorescence decreases.

Explanation:

Olfactory receptors are commonly known as olfactory ordants receptors that are located on the cell membrane of olfactory receptor nerves. They are mainly used for the detection of different types of smell.

Olfactory receptor response is used t measure the functioning of the olfactory receptor.  The fluorescence element labelled with calcium used in this type of fluorescence. The activation of ORN can be measured by the fluorescence activity. The decrease in fluorescence is associated with the increase in the activation of ORN.

Thus, the correct answer is option (b).

it's unlikely a majority of a large population would agree on issues

hope this : )
