Top-down inference in the auditory system: potential roles for corticofugal projections

A Asilador, DA Llano - Frontiers in Neural Circuits, 2021 - frontiersin.org
It has become widely accepted that humans use contextual information to infer the meaning
of ambiguous acoustic signals. In speech, for example, high-level semantic, syntactic, or …

Identifying neuron types and circuit mechanisms in the auditory midbrain

AC Drotos, MT Roberts - Hearing research, 2024 - Elsevier
The inferior colliculus (IC) is a critical computational hub in the central auditory pathway.
From its position in the midbrain, the IC receives nearly all the ascending output from the …
