Heschl's gyrus is more sensitive to tone level than non-primary auditory cortex [PDF]
, 2002 Previous neuroimaging studies generally demonstrate a growth in the cortical response with an increase in sound level. However, the details of the shape and topographic location of such growth remain largely unknown.

The Auditory Cortex in Schizophrenia [PDF]
Biological Psychiatry, 2007 Sweet et al have recently shown that the somal volume of pyramidal cells is reduced in layer 3 of the auditory cortex in schizophrenic patients (Sweet et al 2004; Sweet et al 2003). In this issue of Biological Psychiatry, they report new data showing that the density of axon terminals is also significantly decreased in the same layer (Sweet et al 2006).

Corticofugal modulation of peripheral auditory responses
Frontiers in Systems Neuroscience, 2015 The auditory efferent system originates in the auditory cortex and projects to the medial geniculate body, inferior colliculus, cochlear nucleus and superior olivary complex reaching the cochlea through olivocochlear fibers.

Frontiers in Integrative Neuroscience, 2010 We evaluated to what extent the influence of eye position in the auditory pathway of primates can be described as a gain field. We compared single unit activity in the inferior colliculus (IC), core auditory cortex (A1) and the caudomedial belt (CM ...

An fMRI Study of Audiovisual Speech Perception Reveals Multisensory Interactions in Auditory Cortex. [PDF]
PLoS ONE, 2013 Research on the neural basis of speech-reading implicates a network of auditory language regions involving inferior frontal cortex, premotor cortex and sites along superior temporal cortex.

The state of tranquility: Subjective perception is shaped by contextual modulation of auditory connectivity [PDF]
, 2010 In this study, we investigated brain mechanisms for the generation of subjective experience from objective sensory inputs. Our experimental construct was subjective tranquility.

Extensive Tonotopic Mapping across Auditory Cortex Is recapitulated by spectrally directed attention and systematically related to Cortical Myeloarchitecture [PDF]
, 2017 Auditory selective attention is vital in natural soundscapes. But, it is unclear how attentional focus on the primary dimension of auditory representation - acoustic frequency - might modulate basic auditory functional topography during active listening.

Hearing through your eyes: neural basis of audiovisual cross-activation, revealed by transcranial alternating current stimulation [PDF]
, 2019 Some people experience auditory sensations when seeing visual flashes or movements. This prevalent synaesthesia-like ‘visual-evoked auditory response’ (vEAR) could result either from over-exuberant cross-activation between brain areas, and/or reduced ...

Functional maps of human auditory cortex: effects of acoustic features and attention. [PDF]
PLoS ONE, 2009 While human auditory cortex is known to contain tonotopically organized auditory cortical fields (ACFs), little is known about how processing in these fields is modulated by other acoustic features or by attention.We used functional magnetic resonance ...

Periodicity and frequency coding in human auditory cortex [PDF]
, 2006 Understanding the neural coding of pitch and frequency is fundamental to the understanding of speech comprehension, music perception and the segregation of concurrent sound sources. Neuroimaging has made important contributions to defining the pattern of
