Further unsuccessful treatment included a long-term disruption of the axonal projections from the primary olfactory sensory neurons onto the olfactory bulb.
The selectivity of sensilla coeloconica olfactory sensory neurons was investigated and demonstrated sensitivity to fifteen vertebrate-related volatiles, including ammonia.
However, the olfactory sensory neurons to which olfactory bulb neurons are connected are also distributed across the receptor sheet (the olfactory epithelium) depending on their chemical preferences.
