Since the immune system is regulated by the pineal gland, which exerts immunomodulatory action with the secretion of melatonin and profound effects on electrical activity in the hippocampus, cerebellum and reticular formation structures, we have used magnetoencephalogram (MEG) recordings from MS patients in order to find any differentiation in brain activity in comparison with controls.</p><p><strong>Methods: </strong>Ten MS patients and 10 controls were included in this study. The measurements were performed with a superconducting quantum interference device (SQUID) in an electrically shielded room. For each patient the magnetic activity was recorded from a total of 32 points of the skull as defined by a recording reference system, which is based on the International 10-20 Electrode Placement System.</p><p><strong>Results: </strong>The biomagnetic signals (waveforms) were expressed in terms of magnetic power spectral amplitudes in the frequency range of 2-7 Hz. Some of the recorded points were observed to exhibit abnormal rhythmic activity, characterized by lower amplitudes and frequencies compared with controls.

Fourteen women (28 hands) with EMG/NCS findings of CTS were observed and classified in 3 groups according to electrophysiological severity.

The term ''brain plasticity'' encompasses all possible mechanisms of neuronal reorganization: recruitment of pathways that are functionally homologous to, but anatomically distinct from, the damaged ones (eg, non-pyramidal corticospinal pathways), synaptogenesis, dendritic arborisation and reinforcement of existing but functionally silent synaptic connections (particularly at the periphery of core lesion). The study of neuroplasticity has clearly shown the ability of the developing brain--and of the adult and ageing brain--to be shaped by environmental inputs both under normal conditions (ie, learning) and after a lesion. Neuronal aggregates adjacent, or distant to a lesion in the sensorimotor area can progressively adopt the function of the injured area. Imaging studies indicate that recovery of motor function after a lesion (i.e. stroke) is associated with a progressive change of activation patterns in specific brain structures. Transcranial magnetic stimulation (TMS) and magnetoencephalography (MEG) can detect reshaping of sensorimotor areas; they have a high temporal resolution but have several limitations. TMS can only provide bidimensional scalp maps and MEG depicts three-dimensional spatial characteristics of virtual neural generators obtained by use of a mathematical model of the head and brain. However, the use of objective methods that assess brain reactivity to a physical stimulus (i.e., TMS) or to a sensory input (ie, electrical stimulation to hand and fingers) can integrate information from self-paced motor tasks, because the resolution of abnormal activation over time could be secondary to recovery. Functional MRI (fMRI) and positron emission tomography (PET), on their own, have insufficient time resolution to follow the hierarchical activation of relays within a neural network; however, because of their excellent spatial resolution, they can integrate the findings of TMS and MEG. An integrated approach constitutes, at present, the best way to assess the brain plasticity both under normal conditions and after a lesion.</p>","PeriodicalId":87180,"journal":{"name":"Europa medicophysica","volume":"43 2","pages":"241-54"},"PeriodicalIF":0.0,"publicationDate":"2007-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"26794111","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The neuronal mechanisms underlying this recovery are presently mostly unknown. However, in order to create efficient rehabilitation programs, it is of great importance to uncover these mechanisms. Multiple imaging techniques have been employed for the detection and characterization of ischemic lesions in the brain as well as monitoring of processes associated with stroke recovery. Diffusion and perfusion-weighted magnetic resonance imaging techniques are easy and fast to perform and provide significant information about the ischemic lesion and the hypoperfusion surrounding the lesion at both micro and macrovascular level. More sensitive detection and accurate characterization of the lesion will help in choosing the therapeutic strategies. Methods for monitoring brain function recovery will provide a better understanding of the basic mechanisms of plasticity in the brain, and will serve as a tool for the evaluation of therapeutic interventions, which may eventually include, for example, stem cell transplantation. With the help of these diagnostic tools it may become possible to tailor individual rehabilitation programs.</p>","PeriodicalId":87180,"journal":{"name":"Europa medicophysica","volume":"43 2","pages":"271-84"},"PeriodicalIF":0.0,"publicationDate":"2007-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"26794113","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
