auditory tract (medicine) and Tilsit, Treaties of (sh)


auditory tract (medicine)


auditory tract -->
lateral lemniscus


A bundle of ascending fibres that originate from the cochlear and auditory relay nuclei of the rhombencephalon, enter the trapezoid body, a transverse fibre stratum in which about half their number decussate, and from here turn rostrally along the lateral side of the spinothalamic tract; in the midbrain, it arches dorsally and enters the inferior colliculus in which all of its fibres terminate; the auditory pathway is transsynaptically extended from here by the brachium of the inferior colliculus to the medial geniculate body of the thalamus, from which in turn the auditory radiation leads to the auditory cortex; intercalated in the trapezoid body and along the ascending trajectory of the lemniscus are several cell groups in which part of the fibres synapse.

Synonym: lemniscus lateralis, acoustic lemniscus, auditory lemniscus, auditory tract, lateral fillet.


Tilsit, Treaties of (sh)




(1807) Agreements that France signed separately with Russia and Prussia at Tilsit, northern Prussia (now Sovetsk, Russia).

The treaties followed Napoleon's victories in the Napoleonic Wars and established his supremacy in western and central Europe. France and Russia became allies and divided Europe between them, reducing Prussia and Austria to helplessness. In secret provisions, Russia joined the Continental System against British trade. By 1810 Russian trade was hampered and the tsar opened Russian ports to neutral ships, causing the alliance to fail and paving the way for Napoleon's invasion of Russia in 1812.
