The C. elegans AWC olfactory circuit has much in common with vertebrate rod and cone circuits. Light _____________ cones, inhibiting _____________ release. OFF bipolar cells with _____________ glutamate receptors are hyperpolarized, while ON bipolar cells with _____________ glutamate receptors are depolarized. Similarly, odorant binding _____________ AWC, inhibiting glutamate release. AIB expresses a(n) _____________ glutamate receptor and is hyperpolarized. AIY expresses a glutamate-gated _____________ channel and is depolarized. In both cases, parallel pathways serve to enhance contrast between the presence and absence of the stimulus.
acetylcholine hyperpolarizes
calcium ionotropic
chloride mechanosensitive
depolarizes metabotropic
glutamate sodium
