Johnston organ neuron tonically activated by arista deflection 2009-11-20T01:45:16Z These neurons respond to deflections of the arista such as those caused by a static stimuli like the gravitational force or to larger displacements such as those caused by the wind (Yorozu et al., 2009). fly_anatomy.ontology Johnston organ neuron (JON) whose response is maintained so long as unidirectional aristal deflection is sustained. Their axons tend to be found medially within the JON bundle (Patella and Wilson, 2018).
