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 …

Corticothalamic pathways in auditory processing: recent advances and insights from other sensory systems
The corticothalamic (CT) pathways emanate from either Layer 5 (L5) or 6 (L6) of the
neocortex and largely outnumber the ascending, thalamocortical pathways. The CT …

Sensory overamplification in layer 5 auditory corticofugal projection neurons following cochlear nerve synaptic damage
Abstract Layer 5 (L5) cortical projection neurons innervate far-ranging brain areas to
coordinate integrative sensory processing and adaptive behaviors. Here, we characterize a …

Hearing in complex environments: auditory gain control, attention, and hearing loss
Listening in noisy or complex sound environments is difficult for individuals with normal
hearing and can be a debilitating impairment for those with hearing loss. Extracting …

What can we learn from inactivation studies? Lessons from auditory cortex
Inactivation experiments in auditory cortex (AC) produce widely varying results that
complicate interpretations regarding the precise role of AC in auditory perception and …

The associative thalamus: a switchboard for cortical operations and a promising target for schizophrenia
Schizophrenia is a brain disorder that profoundly perturbs cognitive processing. Despite the
success in treating many of its symptoms, the field lacks effective methods to measure and …

When and how does the auditory cortex influence subcortical auditory structures? New insights about the roles of descending cortical projections
For decades, the corticofugal descending projections have been anatomically well
described but their functional role remains a puzzling question. In this review, we will first …
