The mediodorsal thalamic nucleus and schizophrenia.
The mediodorsal nucleus of the human thalamus is in a crucial position that allows it to establish connections with diverse cerebral structures, particularly the prefrontal cortex. The present review examines existing neurobiologic studies of the brains of people with and without schizophrenia that indicate a possible involvement of the mediodorsal nucleus in this psychiatric disorder. Studies ...
متن کاملThalamic mediodorsal nucleus and working memory.
Working memory is a dynamic neural system for temporarily maintaining and processing information. The prefrontal cortex (PFC) plays an important role in working memory. However, several evidences indicate that the thalamic mediodorsal nucleus (MD) also participates in working memory. Neurophysiological studies revealed that MD neurons exhibit sustained delay activity, which is considered to be ...
متن کاملThe prefrontal cortex: Projection area of the thalamic mediodorsal nucleus?
The historical bases of the definitions of the prefrontal cortex are reviewed (cytoarchitecture, electrical unexcitability, afferents from the mediodorsal thalamic nucleus). Evidence is presented that the widely accepted proposal of Rose and Woolsey (1948) to name all cortex prefrontal that is reached by afferents from the mediodorsal nucleus is questionable for three reasons: the diversity of ...
متن کاملSubcortical afferents to the mediodorsal thalamic nucleus of the dog.
The subcortical afferents of the mediodorsal thalamic nucleus (MD) were studied using the method of retrograde horseradish peroxidase transport. Analysis of the distribution of labeled cells following injections into particular MD segments established specific and unspecific projections originating in various subcortical structures. The medial MD segment is related to such structures of the lim...
متن کاملThe olfactory thalamus: unanswered questions about the role of the mediodorsal thalamic nucleus in olfaction
The mediodorsal thalamic nucleus (MDT) is a higher order thalamic nucleus and its role in cognition is increasingly well established. Interestingly, components of the MDT also have a somewhat unique sensory function as they link primary olfactory cortex to orbitofrontal associative cortex. In fact, anatomical evidence firmly demonstrates that the MDT receives direct input from primary olfactory...
