Abstract

Anatomic and Functional Importance of Thalamus
Thalamus is the grey material substance which has important roles either in transmitting several senses to the primer sense center in cerebral cortex or in transmitting the informations which come from cerebellum and basal ganglions to the motor zone of cerebral cortex. Thalamus has nucleuses which are responsible of the functions. These nucleuses are also in relation with the central nerve system. Roles of thalamus in neurologic diseases such as dementia, epilepsy, multiple sclerosis and migraine have been demonstrated in several studies. Therefore thalamus is small in volume but important in function in neurology practice.



Talamus, hem çeşitli duyuların serebral korteksteki primer duyu merkezine iletilmesinde, hem de serebellum ve bazal gangliyonlardan gelen hareket ile ilgili bilgilerin serebral kortek-sin motor bölgelerine iletilmesinde önemli rolü olan gri cevher kitlesidir. Talamus'un fonksiyonlarının sağlanmasında görevli çekirdekleri vardır. Yine bu çekirdeklerin diğer MSS yapılarıyla bağlantıları vardır. Talamus'un demans, epilepsi, multiple skleroz, migren gibi önemli nörolojik hastalıklarda da rolü yapılan çalışmalarda ortaya konmuştur. Bu nedenle talamus boyut olarak küçük ancak fonksiyon olarak nöroloji pratiğinde önemli bir yere sahiptir.
