Fiber Track Length Gradients in the Avian Sound Localization Circuit Require Conduction Velocity Gradients to Maintain Isochronicity. [PDF]
J Comp NeurolThe gross anatomy of the sound localization circuit in the chicken brainstem was quantified with 3D reconstructions from serial sections and measurements of the interconnecting pathways. A rostral‐to‐caudal length gradient was measured in both the crossed dorsal cochlear track and the ipsilateral loop.

Multimodal Imaging Reveals Cerebral Microcirculation Dynamics and Mechanisms in Mouse Central Nervous System After Intranasal Infection With Recombinant Pseudorabies Virus. [PDF]
Adv Sci (Weinh)Multi‐modality imaging strategy applied to PRV‐induced central nervous system infection enables dynamic visualization of cerebrovascular dysfunction, including hyperemia, hypoperfusion, and vascular remodeling. These changes are linked to microglial activation and impaired angiogenesis, providing mechanistic insight into PRV neuropathogenesis and ...

Frequency-Invariant Representation of Interaural Time Differences in Mammals [PDF]
, 2011 Interaural time differences (ITDs) are the major cue for localizing low-frequency sounds. The activity of neuronal populations in the brainstem encodes ITDs with an exquisite temporal acuity of about .

Neural delays shape selectivity to interaural intensity differences in the lateral superior olive [PDF]
, 1996 Neurons in the lateral superior olive (LSO) respond selectively to interaural intensity differences (IIDs), one of the chief cues used to localize sounds in space.

Adjustment of interaural-time-difference analysis to sound level [PDF]
, 2010 To localize low-frequency sound sources in azimuth, the binaural system compares the timing of sound waves at the two ears with microsecond precision. A similarly high precision is also seen in the binaural processing of the envelopes of high-frequency ...

Source localization in complex listening situations: Selection of binaural cues based on interaural coherence [PDF]
The Journal of the Acoustical Society of America, 2004 In everyday complex listening situations, sound emanating from several different sources arrives at the ears of a listener both directly from the sources and as reflections from arbitrary directions. For localization of the active sources, the auditory system needs to determine the direction of each source, while ignoring the reflections and ...

Population Coding of Interaural Time Differences in Gerbils and Barn Owls [PDF]
, 2010 Interaural time differences (ITDs) are the primary cue for the localization of low-frequency sound sources in the azimuthal plane. For decades, it was assumed that the coding of ITDs in the mammalian brain was similar to that in the avian brain, where ...
