Distinct correlation structure supporting a rate-code for sound localization in the owl's auditory forebrain

MV Beckert, R Pavão, JL Peña - Eneuro, 2017 - eneuro.org
While a topographic map of auditory space exists in the vertebrate midbrain, it is absent in
the forebrain. Yet, both brain regions are implicated in sound localization. The …

Tuning to interaural time difference and frequency differs between the auditory arcopallium and the external nucleus of the inferior colliculus

K Vonderschen, H Wagner - Journal of Neurophysiology, 2009 - journals.physiology.org
Barn owls process sound-localization information in two parallel pathways, the midbrain and
the forebrain pathway. Exctracellular recordings of neural responses to auditory stimuli from …

Auditory Competition and Coding of Relative Stimulus Strength across Midbrain Space Maps of Barn Owls

AJ Bae, R Ferger, JL Peña - Journal of Neuroscience, 2024 - Soc Neuroscience
The natural environment challenges the brain to prioritize the processing of salient stimuli.
The barn owl, a sound localization specialist, exhibits a circuit called the midbrain stimulus …

Barn owl's auditory space map activity matching conditions for a population vector readout to drive adaptive sound-localizing behavior

R Ferger, K Shadron, BJ Fischer… - Journal of …, 2021 - Soc Neuroscience
Space-specific neurons in the owl's midbrain form a neural map of auditory space, which
supports sound-orienting behavior. Previous work proposed that a population vector (PV) …

Localization and identification of concurrent sounds in the owl's auditory space map

CH Keller, TT Takahashi - Journal of Neuroscience, 2005 - Soc Neuroscience
In nature, sounds from multiple sources sum at the eardrums, generating complex cues for
sound localization and identification. In this clutter, the auditory system must determine “what …

Development of frequency tuning shaped by spatial cue reliability in the barn owl's auditory midbrain

K Shadron, JL Peña - Elife, 2023 - elifesciences.org
Sensory systems preferentially strengthen responses to stimuli based on their reliability at
conveying accurate information. While previous reports demonstrate that the brain reweighs …

Populations of auditory cortical neurons can accurately encode acoustic space across stimulus intensity

LM Miller, GH Recanzone - Proceedings of the National …, 2009 - National Acad Sciences
The auditory cortex is critical for perceiving a sound's location. However, there is no
topographic representation of acoustic space, and individual auditory cortical neurons are …

Sound localization in barn owls studied with manipulated head-related transfer functions: beyond broadband interaural time and level differences

P Schillberg, S Brill, P Nikolay, R Ferger… - Journal of Comparative …, 2020 - Springer
Interaural time and level differences are important cues for sound localization. We wondered
whether the broadband information contained in these two cues could fully explain the …

Distribution of interaural time difference in the barn owl's inferior colliculus in the low-and high-frequency ranges

H Wagner, A Asadollahi, P Bremen… - Journal of …, 2007 - Soc Neuroscience
Interaural time differences are an important cue for azimuthal sound localization. It is still
unclear whether the same neuronal mechanisms underlie the representation in the brain of …

Effects of interaural decorrelation on neural and behavioral detection of spatial cues

K Saberi, Y Takahashi, M Konishi, Y Albeck, BJ Arthur… - Neuron, 1998 - cell.com
The detection of interaural time differences (ITDs) for sound localization critically depends
on the similarity between the left and right ear signals (interaural correlation). We show that …
