The Neuronal Basis of Predictive Coding Along the Auditory Pathway: From the Subcortical Roots to Cortical Deviance Detection.

Guillermo V Carbajal, Manuel S Malmierca

PMID 30022729

WHAT IT FOUND

This paper reviews how the brain detects unexpected sounds using animal and human data.

It discusses neural mechanisms like mismatch negativity and predictive coding but reports no clinical outcomes or treatments for therapists.

What this paper is

This is a theoretical review article discussing the neurophysiological mechanisms of auditory deviance detection (specifically the mismatch negativity and stimulus-specific adaptation) in animal and human models. It synthesizes existing literature on predictive coding and neural hierarchies but reports no new clinical trials, patient outcomes, or therapeutic interventions. Consequently, there are no direct findings here to change clinical practice.

Declared interests

The work was supported by the Spanish MINECO (Ministry of Science, Innovation and Universities).

The easy way to misread this

Do not interpret this review as evidence for a new assessment tool or therapy. It describes basic science mechanisms of how the auditory system processes change, not how to treat patients with auditory processing disorders.
