In vitro odor-aversion conditioning in a terrestrial mollusk.
We developed an in vitro odor-aversion conditioning system in the terrestrial mollusk, Limax, and found a behavioral correlate of network oscillation in the olfactory CNS. We first examined the odor-induced behavior of Limax, after odor-aversion conditioning in vivo. Shortening of mantle muscles was specifically observed in response to aversively conditioned odors. We previously identified that...
متن کاملIn vitro study of odor-evoked behavior in a terrestrial mollusk.
To explore neural mechanisms how olfactory information is processed in the brain and finally converted into behavior, it would be useful to have isolated whole brains that include both olfactory organs and motor output. In the present study, we identified an in vitro index of odor-evoked behavior in the terrestrial mollusk Limax and also studied the modulation of this in vitro index of the beha...
متن کاملCentral and reflex neuronal responses elicited by odor in a terrestrial mollusk.
1. We studied the responses to odor of a central olfactory processing organ and subsequent central outputs in the terrestrial mollusk Limax maximus. We used extracellular recording techniques and optical recording from preparations stained with a voltage-sensitive dye to characterize network responses in the central organ and whole nerve recording to characterize central odor-elicited outputs. ...
متن کاملTwo types of network oscillations and their odor responses in the primary olfactory center of a terrestrial mollusk.
We identified two classes of network oscillations with different frequency ranges in the tentacle ganglion (TG), the primary olfactory center of the terrestrial mollusk Limax marginatus, and investigated the responses of these oscillations to odor inputs. A recent study indicated that there are serotonergic terminals in the TG. We found that when serotonin was applied to the TG, the spontaneous...
متن کاملBehavioral determination of odor preference is coded by the oscillation frequency in a collective oscillating network of a terrestrial mollusk.
The brain receives sensory inputs, processes them and finally produces outputs in the form of behavior. In olfaction, many excellent studies have clarified the initial step of neural processing. However, the next step, i.e. how the meaning of the odor is added to the recognized quality of the chemical odor, is poorly understood. This is a critical problem in brain science, because the meaning o...
