H2rn [FBbt_00053519]

Adult unilateral interneuron that arborizes in the inferior posterior slope, receiving input from contralateral H2 cells and forming feedback connections selectively with them (Erginkaya et al., 2025). It is GABAergic (Erginkaya et al., 2025). There are approximately 5 of these cells per hemisphere (Erginkaya et al., 2025).
