[Thalamo-cortical dysrhythmia syndrome: neuropsychiatric features]

One of the essential aspects of the neuronal organization in the global function of the brain is the rich thalamocortical interconnectivity and very particularly the reciprocal nature of this circuit. Also, the interaction between the systems specific thalamic and unspecific at cortical level suggests that the thalamus, more than a simple floodgate for the brain, represents an epicentre by means of which all the cortical areas can communicate to each other in isochronic way with independence of the transcortical distance. The objectives of this article are to explore: 1) the proposal that the temporary coincidence, to great scale, of the activity specific thalamic and unspecific generates the functional states that characterize the human knowledge; and 2) the possible relationship between the thalamocortical dysrhythmia and some neuropsychiatric illnesses.
