A recency effect in sound localization?

Recency effect in multiple sclerosis.

The main object of this study was to test acquisition-retrieval deficits in multiple sclerosis (MS) patients A Spanish version of the Rey Auditory-Verbal Test (RAVLT) (Rey 1964) was used with an MS group (n=10 subjects) and a control group (n=10) Different measurements were obtained with the RAVLT memory span, a learning curve, and a curve of serial position of words The results revealed no dif...

Sound Localization in a Sound Field Represented by Spherical Harmonics

Sound localization is an important aspect in human hearing, with interaural time difference (ITD) and interaural level difference (ILD) as two binaural cues that complement each other in this goal. Head related transfer functions (HRTFs) can be used to estimate and analyze these cues, where an HRTF representation in the spherical harmonics domain has recently been suggested for analysis. The ai...

Tonotopic tuning in a sound localization circuit.

Nucleus laminaris (NL) neurons encode interaural time difference (ITD), the cue used to localize low-frequency sounds. A physiologically based model of NL input suggests that ITD information is contained in narrow frequency bands around harmonics of the sound frequency. This suggested a theory, which predicts that, for each tone frequency, there is an optimal time course for synaptic inputs to ...

Sound Localization in a Meeting Room

Sound localization in a changing world

In natural environments, neural systems must be continuously updated to reflect changes in sensory inputs and behavioral goals. Recent studies of sound localization have shown that adaptation and learning involve multiple mechanisms that operate at different timescales and stages of processing, with other sensory and motor-related inputs playing a key role. We are only just beginning to underst...
