“…To analyze the echoes and pulses themselves, auditory nuclei of bats are remarkably hypertrophied (Zook & Casseday, 1982a), and show specialization related to echolocation (Covey & Casseday, 1995), which is obvious in the medial superior olive (MSO) of the superior olivary complex (SOC) (Casseday, Covey, & Vater, 1988; Covey, Vater, & Casseday, 1991; Grothe, Park, & Schuller, 1997; Grothe, Schweizer, Pollak, Schuller, & Rosemann, 1994) and monaural nuclei of the lateral lemniscus, namely intermediate nucleus (ILL) and compact and multipolar cell divisions of ventral nucleus (VLLc and VLLm) (Covey & Casseday, 1991). Lower brainstem nuclei, namely, cochlear nuclei (CN), SOC, and nuclei of the lateral lemniscus (NLL), analyze specific features of sound and send the analyzed information to the inferior colliculus (IC), which is the largest nuclei in entire subcortical auditory system (Ito, Bishop, & Oliver, 2016).…”
