Accurate temporal coding of low-frequency tones by spikes that are locked to a particular phase of the sine wave (phase-locking), occurs among certain groups of neurons at various processing levels in the brain. Phase-locked responses have previously been studied in the inferior colliculus and neocortex of the guinea pig and we now describe the responses in the auditory thalamus. Recordings were made from 241 single units, 32 (13%) of which showed phase-locked responses. Units with phase-locked… 
A Role for Auditory Corticothalamic Feedback in the Perception of Complex Sounds
TLDR
It is demonstrated that mistuning sensitivity in the thalamus is demonstrated and that feedback from the primary auditory cortex is required for the normal ability of ferrets to detect a mistuned harmonic within a complex sound.
Correlation of neural response properties with auditory thalamus subdivisions in the awake marmoset.
TLDR
This work has recorded from neurons in the auditory thalamus of awake marmoset monkeys and tested their responses to tones, band-pass noise, and temporally modulated stimuli, forming the basis for parallel output channels.
Auditory cortical generators of the Frequency Following Response are modulated by intermodal attention
TLDR
By showing a clear cortical contribution to the attentional FFR effect, this work significantly extends previous reports that focus on surface level recordings only and underlines the importance of making a greater effort to disentangle the different contributing sources of the FFR.
Correlation of neural response properties with 1 auditory thalamus subdivisions in the awake marmoset 2 3 4 5
TLDR
The spectral and temporal response properties of recorded neurons were analyzed and correlated with their locations in the auditory thalamus, thereby forming the basis for parallel output channels and indicating responses consistent with providing thalamocortical input to core regions whereas MGPD neurons are consistent with provide input to belt regions.
Temporal Coding of Voice Pitch Contours in Mandarin Tones
TLDR
The difference between the number of LFPs and single neurons that encode the time-variant F0 voice pitch supports the notion of a transition at the level of IC from direct temporal coding in the spike trains of individual neurons to other form of neural representation.
Coding of communication calls in the subcortical and cortical structures of the auditory system.
TLDR
The investigation of the principles of the neural coding of species-specific vocalizations offers some keys for understanding the neural mechanisms underlying human speech perception.
Binaural unmasking of frequency-following responses in rat amygdala.
TLDR
The results suggest that both frequency-dependent ascending binaural modulations and cortical descending modulations of the precise auditory coding of the chatter in the amygdala are critical for processing life-threatening acoustic signals in noisy and even reverberant environments.
Subcortical and cortical tracking of communication sound envelopes in challenging listening conditions
TLDR
It is suggested that slow envelope tracking is a general property of auditory neurons, and any difference between the slow envelopes of natural stimuli allows coping with degraded conditions.

Phase-locked responses to pure tones in the inferior colliculus.
TLDR
It is concluded that many cells in the central nucleus receive direct inputs from the brain stem, whereas Cells in the external and dorsal divisions receive input from other structures that may include the forebrain.

Enhancement of neural synchronization in the anteroventral cochlear nucleus. I. Responses to tones at the characteristic frequency.
TLDR
Auditory nerve fibers synchronize or phase-lock to low-frequency tones and transmit this temporal information to cells in the anteroventral cochlear nucleus of the AVCN, and it is found that most TB axons exhibited enhanced synchronization compared with AN fibers.
Monaural and binaural response properties of neurons in the inferior colliculus of the rabbit: effects of sodium pentobarbital.
TLDR
Injections of sodium pentobarbital at subsurgical dosages almost invariably altered the neuron's response rate, response latency, response pattern, and spontaneous activity, which were predictable and consistent with an enhancement of inhibitory influences.
A comparison of the interaural time sensitivity of neurons in the inferior colliculus and thalamus of the unanesthetized rabbit
TLDR
Differences in ITD sensitivity, such as the sharper tuning for ITDs, suggest that the thalamus is not a simple relay, and enhanced sensitivity to ITDs should translate to better-defined azimuthal receptive fields, and therefore may be a step toward achieving an optimal representation of azIMuth within the auditory pathway.
