Imaging of Thalamocortical Dysrhythmia in Neuropsychiatry
Abnormal brain activity dynamics, in the sense of a thalamocortical dysrhythmia (TCD), has been proposed as the underlying mechanism for a subset of disorders that bridge the traditional delineations of neurology and neuropsychiatry. In order to test this proposal from a psychiatric perspective, a study using magnetoencephalography (MEG) was implemented in subjects with schizophrenic spectrum d...
متن کاملThalamocortical dysrhythmia and chronic pain
The paper byWalton et al. [13] in this issue of Pain brings a new perspective to the problem of central pain, in this case complex regional pain syndrome without peripheral nerve injury (CRPSI). It is a perspective that may have escaped the notice of many pain scientists and sensory physiologists. Walton et al. [13] using magnetoencephalography (MEG) compared brain activity in sufferers from ty...
متن کاملThalamocortical Dysrhythmia: A Theoretical Update in Tinnitus
Tinnitus is the perception of a sound in the absence of a corresponding external sound source. Pathophysiologically it has been attributed to bottom-up deafferentation and/or top-down noise-cancelling deficit. Both mechanisms are proposed to alter auditory -thalamocortical signal transmission, resulting in thalamocortical dysrhythmia (TCD). In deafferentation, TCD is characterized by a slowing ...
متن کاملVisual snow: A thalamocortical dysrhythmia of the visual pathway?
In this paper we review the visual snow (VS) characteristics of a case cohort of 32 patients. History of symptoms and associated co-morbidities, ophthalmic examination, previous investigations and the results of intuitive colourimetry were collected and reviewed. VS symptoms follow a stereotypical description and are strongly associated with palinopsia, migraine and tinnitus, but also tremor. T...
متن کاملThalamocortical dysrhythmia: A neurological and neuropsychiatric syndrome characterized by magnetoencephalography.
Spontaneous magnetoencephalographic activity was recorded in awake, healthy human controls and in patients suffering from neurogenic pain, tinnitus, Parkinson's disease, or depression. Compared with controls, patients showed increased low-frequency theta rhythmicity, in conjunction with a widespread and marked increase of coherence among high- and low-frequency oscillations. These data indicate...
