Koklear Nukleusun Nöron Çeşitleri
Koklear nukleus akustik sinir kökünün girişinde pons ile medulla oblongata arasındaki sınırda yerleşen ve akustik sinirden sinaptik terminal alan ilk nöranal merkezdir. Koklear nukleus kohledan gelen tüm efferent çıkışları alan çıkıcı işitme yolundaki ilk duraktır. Farklı morfolojik ve fizyolojik tipte nöronlar içeren koklear nukleus, ventral koklear nucleus ve dorsal koklear nucleus olmak üzere iki kısımdan oluşur. Koklear nukleus, işitme ve dolayısıyla lisan gelişimi ve öğrenme ile de ilgili olduğundan birçok morfolojik ve fizyolojik çalışmalar bu nukleusta yapılmıştır.

Neuron Types Of Cochlear Nucleus
The cochlear nuclei, located at the border between the medulla oblongata and pons around the point of entrance of acoustic nerve root, are the first neuronal centres to receive synaptic terminals from the acoustic nerve. The cochlear nucleus is the first relay station of the ascending auditory pathway that receives all efferent output coming from the cochlea. The cochlear nucleus is divided into a ventral part and a dorsal part, consisting of morphologically and physiology distinct types of neurons. Because the cochlear nucleus is related to hearing, it is also associated with language development and learning, therefore many morphological and physiological studies have been done in this nucleus.
