Bondok's Classification of the Thalamic Nuclei
Anatomists usually classify the thalamic nuclei according to their relation to the internal medullary lamina into 5 groups: anterior, medial (centromedian), lateral, intralaminar and reticular nuclei. The lateral nucleus is further divided into ventral and dorsal groups. The dorsal tier nuclei include the lateral dorsal, lateral posterior and pulvinar. The ventral tier nuclei include the ventral anterior, ventral lateral, ventral posterior and the metathalamus (medial and lateral geniculate bodies). On the other hand, physiologists divide the thalamic nuclei according to their connections (input and output) into specific and nonspecific nuclei. The medical students are usually puzzled between the 2 classifications.
To make it understandable and simple, I adopted a new classification based on their main function and connections so that medical students can easily recognize them and remember their function. I called this classification "Bondok's Classification of the Thalamic Nuclei". I divided the thalamic nuclei into 5 groups:
