This chapter explores the structural and functional organization of the inferior colliculus (IC), the midbrain nucleus of the auditory pathway. The IC receives parallel ascending connections from a multiplicity of brainstem nuclei, together with descending projections from the cerebral cortex. Its output supplies the auditory thalamus and tectum.

The Intercollicular Area of the Inferior Colliculus
Brain, Behavior and Evolution, 1976To study the somatosensory input to the inferior colliculus, lesions were made in the dorsal column nuclei of the hedgehog, tree shrew, slow loris, marmoset and African green monkey, and spinal cord of the hedgehog, tree shrew and slow loris. The degenerating fibers stained with silver impregnation methods.

Anatomy of the inferior colliculus in rat
Anatomy and Embryology, 1985This paper defines the pattern of subdivision of the inferior colliculus in rat. It is based on serial sections of brains of albino and hooded rats cut in the frontal, sagittal and horizontal planes using Golgi, Nissl and a combined cell-myelin method.

Combination-sensitive neurons in the inferior colliculus
Hearing Research, 1995We examined whether neurons in the inferior colliculus of the mustached bat (Pteronotus parnellii) are combination sensitive, responding to both low- and high-frequency components of the bat's sonar signal. These neurons, previously reported in the thalamus and cortex, analyze sonar target features including distance. Of 82 single units and 36 multiple

Ascending projections to the inferior colliculus
Journal of Comparative Neurology, 1979AbstractCells that send ascending projections to the inferior colliculus were identified following injections of horseradish peroxidase into the colliculus. Labelled cells were found in all subcollicular auditory nuclei. Virtually all cells of the ipsilateral ventral nucleus of the lateral lemniscus and medial superior olive appear to project to the ...

Projections of the inferior colliculus in cat
Journal of Comparative Neurology, 1969AbstractProjections of the feline inferior colliculus were studied using the Nauta‐Laidlaw method to demonstrate degenerating axons. A subtentorial stereotaxic approach was used to avoid corticofugal degeneration. Direct connections from the inferior colliculus to the anterior midline cerebellar cortex were observed.

Wakefulness-promoting role of the inferior colliculus
Behavioural Brain Research, 2013The inferior colliculus (IC) is a mesencephalic auditory nucleus involved in several functions including the analysis of the frequency and intensity of sounds as well as sound localization. In addition to auditory processes, the IC controls the expression of defensive responses.

Mechanisms of defense in the inferior colliculus
Behavioural Brain Research, 1993The inferior colliculus (IC) is a well known relay station for auditory pathways in the brainstem. In the present review we are suggesting that aversive states are also generated and elaborated in the inferior colliculus and that this structure may be part of a brain system commanding defensive behavior. The evidences presented in this review have been

Spectral Processing in the Inferior Colliculus
2005Publisher Summary This chapter reviews the anatomy of a mammalian. The frequency response areas of inferior colliculus (ICC) units are described, followed by the roles of the various excitatory and inhibitory inputs to the ICC in shaping these response areas. The functional roles of the ICC in the processing of spectral information are discussed. The

Computational Models of Inferior Colliculus Neurons
2010The inferior colliculus (IC), the principal auditory nucleus in the midbrain, occupies a key position in the auditory system. It receives convergent input from most of the auditory nuclei in the brain stem, and in turn, projects to the auditory forebrain (Winer and Schreiner 2005). The IC is therefore a major site for the integration and reorganization
