Diffusion and MRS in a rat cortex after traumatic injury
Voříšek, Ivan; Herynek, V.; Burian, M.; Hájek, M.; Niclay, K.; Syková, Eva
2001 - English
An increase in diffusion barriers, manifestes by a decrease of both ADCTMA and ADCW, occurs throughout the entire cortex of the wounded hemisphere. These changes are related to astrogliosis and to an accumulation of extracellular matrix molecules without significant changes in ECS volume.

The MGB, is similarly as the inferior colliculus (IC) is organized into three subdivisions, with the ventral MGB characterized by the quickest onset reaction with the lowest thresholds to auditory stimulation and with the same ratio of monotonic and non-monotonic RLFs.

A behavioral and electrophysiological study of the effects of noise exposure on auditory function in rat
Rybalko, Natalia; Mazelová, Jana; Syka, Josef
2001 - English
The values of the gap detection threshold doubled after exposure to 110 dB SPL and quadrupled after exposure to 115-120 dB SPL. GDT recovered to the original values during 1-2 weeks. Increased gap detection thresholds after noise exposure appear connected with elevated hearing thresholds, the deterioration in the performance of some animals in behavioral rasts after strong intensity noise (120 dB SPL) may signal the occurrence of tinnitus in these animals.

Suppression of 2f1-f2 distortion product otoacoustic emissions by electrical stimulation of the inferior colliculus in guinea pigs
Popelář, Jiří; Mazelová, Jana; Syka, Josef
2001 - English
Electrical stimulation of certain parts of the IC resulted in the depression of the DPOAE amplitude by 0.1-2 dB. The value of maximal DPOAE suppression was similar to the DPOAE suppression produced by acoustical stimulation of the contralateral ear. Our results indicate that electrical stimulation of the external cortex of the IC can activate the efferent system and produce DPOAE suppression by similar mechanisms as does acoustical stimulation of the contralateral ear.
