Oflaction Flashcards
1
Q
How many odorant receptor are in mamals
A
~500-1000
2
Q
How many receptor genes does each sensory neuron express?
A
1
3
Q
How are neurons organized
A
Zonally by receptor type
4
Q
What is a glomerulus?
What does it provide?
A
A region of dense neuropil that neurons project to
Amplification
5
Q
How are neurons organized
A
In 4 zones from dorsal medial to ventral lateral
6
Q
What is the relationship between neurons and glomeruli
A
All neurons of same receptor project to same glomerulus on that side
7
Q
What is the relationship between glomeruli?
What does it provide
A
Projects mitral cells to anterior olfactory nucleus to matching glomerulus
-converging info
Possibly more amplification
8
Q
How do odorants activate more than one receptor?
A
They’re made up of multiple receptor agonists
