Functional network properties of the auditory cortex
2023年6月1日 · Here, we discuss and review two gaps in our understanding: (1) the specific and differential contributions of different fields of the auditory cortex to auditory perception and behavior and (2) the way network activity impact and facilitate auditory information processing.
Thalamic and cortical pathways supporting auditory processing
The corpus callosum is the fiber bundle linking the two hemispheres of the auditory cortex, principally the homolateral areas on each side, e.g. AI to AI, while heterolateral connections are less prevalent, e.g. AI to AII (Morel et al., 1993; E. M. Rouiller et al., 1991).
Functional organization of the mammalian auditory midbrain
2015年9月11日 · The IC cortex receives inputs mainly from the ICC and descending fibers from the cerebral cortex [9, 10], which suggests the IC cortex is involved in attention to sound. Interestingly, some neurons in the IC cortex can detect changes in the auditory scene .
The auditory cortex: Current Biology - Cell Press
2007年4月3日 · These messages are then encoded as volleys of action potentials by the axons of the vestibulo-cochlear nerve and transmitted via a complex chain of nuclei in the brainstem, midbrain and thalamus towards the auditory cortex (Figure 1 A), where the interpretation and recognition of sounds is thought to take place.
Auditory pathways: anatomy and physiology - ScienceDirect
2015年1月1日 · The auditory nerve fibers branch to give two pathways, a ventral sound-localizing stream, and a dorsal mainly pattern recognition stream, which innervate the different divisions of the cochlear nucleus.
Sensory overamplification in layer 5 auditory corticofugal …
2018年6月25日 · Deep layer auditory cortex neurons project to a number of limbic and subcortical auditory structures. Here, the authors show how these corticofugal projections adjust response gain following...
Anatomy and physiology of auditory pathways and cortex
2013年1月1日 · Frequency tuning curves derived from neurons in thalamo-recipient layers III and IV of the auditory core cortex of monkeys (and other mammals) may be as sharp and their excitatory response areas as orderly as those obtained from a single auditory nerve fiber; for these cortical neurons very little spectral integration takes place between ...
Progress and challenges for understanding the function of …
2017年12月18日 · In the auditory cortex, a combination of large-scale electrophysiological recordings and concurrent optogenetic manipulations are improving our understanding of the role of...
Structure and function in the auditory system: From cochlea to cortex ...
2006年3月20日 · This beautifully illustrated and well-crafted study demonstrates the association of structure and function in the auditory system on the gross level (i.e., middle ear musculature and ossicular chain attenuation) as well as the cellular level (i.e., neuronal projections and …
Anatomy and Physiology of the Mammalian Auditory System
2014年1月1日 · The auditory nerve (AN) is made of both afferent and efferent fibers (for review, see Slepecky 1996). The afferent fibers transmit impulses from the organ of Corti to the cochlear nuclear complex, while the efferent fibers convey impulses from the superior olivary complex to the organ of Corti (Fig. 1).
