Recovery cycles of single-on and double-on neurons in the inferior colliculus of the leaf-nosed bat, Hipposideros armiger
2011, Brain ResearchCitation Excerpt :For this reason, many studies have been devoted to examining the auditory responses with temporally patterned pulse trains or paired pulses spaced over varied IPI in different mammalian species (Brosch and Schreiner, 1997; Fitzpatrick et al., 1999; Keller and Takahashi, 1996; Litovsky and Yin, 1998; Lu et al., 1997; Lu and Jen, 2002; Parham et al., 1998; Pollak et al., 1977; Suga and Schlegel, 1973; Wang et al., 2008, 2010; Wu and Jen, 1998; Wu and Jen, 2006a,b; Zhou and Jen, 2003). These studies have clearly shown that a neuron's response magnitude to a single sound presented in isolation is often larger than to the same sound presented in temporally patterned pulse trains (Moriyama et al., 1994). Furthermore, a neuron's response size progressively decreases with sequentially presented sound pulses (Jen and Zhou, 1999; Jen et al., 2001, 2002; Lu et al., 1997, 1998; Wu and Jen, 1996; Zhou and Jen, 2002).
Echo frequency selectivity of duration-tuned inferior collicular neurons of the big brown bat, Eptesicus fuscus, determined with pulse-echo pairs
2008, NeuroscienceCitation Excerpt :Similarly, many studies show that a neuron's response to a single pulse can be suppressed when the single pulse is paired with another pulse within an interpulse-interval (Brosch and Schreiner, 1997; Faure et al., 2003; Hocherman and Gilat, 1981; Litovsky and Yin, 1998; Wu and Jen, 2006b). As such, neurons show larger responses to single pulses presented in temporal isolation than in temporally patterned pulse trains (Moriyama et al., 1994). It is therefore possible that this forward neural masking may also account for the sharper echo frequency selectivity of IC neurons obtained with echo pulses of P-E pairs than with single pulses (Fig. 5B).
The role of GABAergic inhibition in shaping the response size and duration selectivity of bat inferior collicular neurons to sound pulses in rapid sequences
2005, Hearing ResearchCitation Excerpt :Therefore, the response size of auditory neurons to a sound pulse would be affected when the sound pulse is preceded and succeeded by other sound pulses (i.e., forward and backward masking). As evident in a previous study, the response size of IC neurons is often larger when stimulated with a single sound pulse than when stimulated with the same sound pulse presented in pulse trains (Moriyama et al., 1994). Furthermore, the response size of IC neurons progressively decreased with sequentially presented sound pulses (Jen and Zhou, 1999; Jen et al., 2001; Lu et al., 1997, 1998; Moriyama et al., 1994; Pinheiro et al., 1991; Wu and Jen, 1995; Zhou and Jen, 2002).
