TLDR
Ferrets tested in a semicircular apparatus were trained to initiate trials while facing forward in the apparatus, and sounds were presented from one of two loudspeakers located in the horizontal plane to determine the effects of auditory cortical lesions on their ability to localize sounds in space.Abstract:

Target neuron prespecification in the olfactory map of Drosophila.

TL;DR: It is demonstrated that projection neurons are prespecified by lineage and birth order to form synapses with specific incoming ORN axons, and therefore to carry specific olfactory information, which could be used to hardwire the fly's Olfactory system, enabling stereotyped behavioural responses to odorants.
Physiological and anatomical evidence for multisensory interactions in auditory cortex
TL;DR: In this paper, the authors demonstrate using single-unit recordings that visually-responsive units are widespread in the auditory cortex of anesthetized ferrets and that these units were also acoustically responsive and frequently transmitted more information in their spike discharge patterns in response to paired visual-auditory stimulation than when either modality was presented by itself.

Organization of auditory cortex in the albino rat: sound frequency.
Sharon L. Sally,Jack B. Kelly +1 more
TL;DR: Responses of neurons in the auditory cortex of the albino rat were examined using microelectrode mapping techniques and suggest the presence of other auditory fields, the detailed characteristics of which have yet to be examined.
Journal ArticleDOI
The descending corticocollicular pathway mediates learning-induced auditory plasticity.
TL;DR: The role of corticocollicular neurons in experience-dependent recalibration of sound localization in adult ferrets is examined by selectively killing the neurons using chromophore-targeted laser photolysis and the integrity of this descending pathway is critical for learning-induced localization plasticity.
Journal ArticleDOI
Location coding by opponent neural populations in the auditory cortex.
TL;DR: A simple model is demonstrated, based on spike-count differences across cortical populations, that provides bias-free, level-invariant localization—and thus also a solution to the “binding problem” of associating spatial information with other nonspatial attributes of sounds.
