Terminology
ORN stands for?
olfactory receptor neuron.
True or False? Olfactions receptors can only function within their native ORN.
False.
Which olfaction organ did we primarily focus on?
The antennae.
Which two organs make up the Drosophila olfaction system?
The maxillary palp and antennae.
What type of map did the authors say they created?
A receptor-to-neuron map.
How many Or genes does Drosophila have?
Around 60.
Δhalo refers to what?
A deletion mutant of the ab3A antenna neuron.
Which two main characteristics were shown to be influenced by olfaction receptors?
Spontaneous firing rate and signaling mode.
Around 1200.
How would you name a mutant neuron with the 7a receptor?
Δab3A:Or7a
The co-expression of inhibitory/excitatory receptors in an ORN produces a(n) _____________ response?
intermediate.
What is meant by the "temporal structure" of olfactory information?
The pattern and presentation of the odorant to the ORN.
Throwback to NEU 335! What are the components of the GAL4/UAS system?
GAL4 = yeast transcription factor
UAS = Binding DNA sequence of GAL4 protein
Explain why the authors included some "extra" odorants in their response spectra.
To demonstrate that Ors are primarily responsible for an ORN's response spectra.
How many odorant receptors does the antennae have?
31.
