Audiogenic seizure (AGS) susceptibility is a reflex epilepsy of rodents in which acoustic stimulation evokes wild running attacks and subsequent convulsions. Susceptibility can be induced in non-susceptible strains by treatments causing transient or permanent hearing losses as long as these occur during the neonatal period.

The interconnections of the inferior colliculi through their commissure
AbstractMuch is known of the sources and manner of termination of ascending and descending input to the inferior colliculus (IC) but its commissural connections are less well understood. Most studies of the commissure have utilized small lesions or tracer deposits; while all agree that commissural axons terminating in the IC do so in its superficial ...

The neuronal loss and the alteration of the synapses in the medial geniculate bodies and the inferior colliculi may be involved in the impairment of communication and symbolic sound perception, which is noticed even in the early stages of Alzheimer's disease.Alzheimer's disease (AD) is a neurodegenerative disorder, causing a progressive decline of ...

AbstractGiven the evidence that the inferior colliculus (IC) and superior colliculus (SC) seem to play key roles in connecting auditory pathways and seizure output pathways in the neuronal network for audiogenic seizures (AS) in rats, we examined Fos activation in GABAergic cells and cells immunopositive for glutamate N‐methyl‐D‐aspartate (NMDA ...

We report a clinical case of a 19-year-old male patient who developed pure word deafness due to the local compressive effect of a pineal germinoma on the inferior colliculi of the quadrigeminal plate. After percutaneous radiation therapy the size of the tumor decreased significantly, while audiometry demonstrated a complete regression of the auditory ...

The topographic organization of neurons in the dorsal nucleus of the lateral lemniscus (DNLL) which project to the superior and inferior colliculi was studied using the retrograde horseradish peroxidase (HRP) and the fluorescent double labeling methods.

In spite of the large quantity of psychophysiological investigations of binaural hearing, a systematic study of its concrete mechanisms has only been begun comparatively recently (cf. review [1]). In particular, changes in neuron response under conditions of lateral differentiation brought about by varying the intensity of one of the monaural ...

Abstract Mice not normally susceptible to audiogenic seizures can be rendered so by exposing them to a brief intense sound during a certain developmental period (acoustic priming). To determine the effects of priming on central auditory activity, single-unit extracellular recordings were obtained from the inferior colliculi of primed C57BL/6J mice ...

[Behavior of cats after unilateral section of the brachii of the inferior colliculi].
In experiments on 13 cats a unilateral section of the brachii of inferior colliculi produced a stable interhemispheric asymmetry not only in the auditory system, but in other (vestibular, visual, somatic, olfactory) analysers as well, which led to a disturbance of adequate space perception.
