Auto-classification of sensory modality. (A) Classification under ‘detection of stimulus involved in sensory perception’. (B) Inferred classification of sensory neuron classes with sensory modality defined using the pattern: EquivalentTo neuron that capable_of some ‘detection of stimulus involved in sensory perception’ or one of its subclasses. (C) Classification and part relationships between subclasses of ‘sensory perception’ and subclasses of ‘detection of stimulus involved in sensory perception’. (D) Populating the auditory system. An auditory system neuron is defined as “any neuron that is capable_of_part_of (some) ‘sensory perception of sound”’. This property is directly asserted for ‘inferior ventrolateral protocerebrum IVLP-IVLP neuron’, and inferred for ‘auditory sensory neuron’, which is defined as “neuron that capable_of (some) ‘detection of mechanical stimulus involved in sensory perception of sound”’. Inference comes from the part relation between the two GO terms and a property chain stating that if X capable_of Y and Y part_of Z then Z capable_of_part_of Z. All auditory system neurons are asserted to be part_of (some) ‘auditory system’, an assertion that is inherited by all classes inferred to be subclasses of ‘auditory system neuron’.
