INTRODUCTION: The supplementary motor area (SMA) is frequently involved by brain tumours (particularly WHO grade II gliomas). Surgery in this area can be followed by the 'SMA syndrome', characterised by contralateral akinesia and mutism. Knowledge of the connections of the SMA can provide new insights on the genesis of the SMA syndrome, and a better understanding of the challenges related to operating in this region. METHODS: White matter connections of the SMA were studied with both postmortem dissection and advance diffusion imaging tractography...

BACKGROUND: A probiotic formulation (Lactobacillus helveticus R0052 and Bifidobacterium longum R0175 combination, Probio'Stick(®) ) displays anxiolytic-like activity and reduces apoptosis in the lymbic system in animal models of depression. Based on the hypothesis that modulation of gut microbiota by this probiotic formulation has beneficial effects on brain activity in stress conditions, we report a set of probiotic-evoked physiological, cellular, and molecular events in the brain of Probio'Stick(®) pretreated mice submitted to chronic psychological stress...

Tianeptine, an atypical tricyclic antidepressant, is one of the first chemical agents, like tricyclic antidepressants and selective serotonin re-uptake inhibitors (SSRIs), which are employed for the treatment of anxiety and depressive disorders. It is believed that tianeptine, unlike the SSRIs, is enhancing serotonin re-uptake the velocity of the cortical neurons in the lymbic system and hippocampal neurons. In literature, there are more examples of dependence cases of antidepressants, which have amphetaminergic effects, such as amineptine and tranylcipromine, than amitriptyline, fluoxetine and tianeptine...

PURPOSE: Previous studies have shown that post-traumatic stress disorder (PTSD) is associated with lymbic system dysfunction. The purpose of this study is to evaluate whether or not the neuronal integrity in hippocampus and anterior cingulate gyrus is affected in PTSD as assessed by proton magnetic resonance spectroscopy. MATERIALS AND METHODS: Single voxel MRS was performed in 10 PTSD patients and 6 healthy subjects in two cerebral areas highly involved in the pathophysiology of PTSD (the hippocampus and the anterior cingulate gyrus)...

We observed the onset time and distribution pattern of beta2 isoform of Ca2+/calmodulin-dependent protein kinase I (CaMKIbeta2) in the CNS of the rat during the embryonic period until birth using an immunohistochemical method. The expression of CaMKIbeta2 started at embryological day 10 when the three primary brain vesicles and neural tube are generated from the neural plate. During the embryonic period, highly immunoreactive products were ubiquitously detected in neurons in the CNS, although neurons in the caudate-putamen and globus pallidus were faintly immunostained or immunonegative...

The central nervous system is an important target for sex steroid hormones. During the climateric period the rapid decline of gonadal steroids causes neuroendocrine changes in different areas of the brain. The failure of gonadal hormone production brings specific symptoms due to the central nervous system derangement. At the hypotalamic level estrogen withdrawal gives rise to vasomotor symptoms, eating behavior disorders and altered blood pressure control. Psychological disturbances such as depression, anxiety, irritability and mood fluctuation are related to estrogen-induced changes in the lymbic system...

The effect of melanostatin (MIF), L-DOPA and morphine on the behaviour and electrical activity in the neocortex and lymbic structures in rats has been strudied. All substances were administered intraventricularly. There was a recorded increase of the energy of the delta and theta slow waves in the hypothalamus, amygdala and neocortex and also of the energy of the alfa waves in the amygdala and neocortex. In addition the administration of L-DOPA and morphine facilitated the effect of MIF while preliminary administration of MIF blocked the effect of morphine given in threshold doses...

Using immunoenzymic assays, the authors studied concentrations of two isoforms of the glycolytic enzyme enolase (neurospecific, NSE, and non-neurospecific, NNE) in different structures of the postmortem brain in mentally normal people (n = 15) and in schizophrenics (n = 9). In schizophrenic patients NSE concentrations were increased by 70% (p less than 0.001) in the sensory cortex and reduced by the same magnitude in the thalamus. Insignificant changes in their levels (by 15-20%, p less than 0.05) were also discovered in the temporal cortex (elevation), lymbic cortex and the hippocampus (decrease)...

The characteristics were studied of focal potentials and impulse activity of 102 neurones of the thalamus dorsomedial nucleus (DMN) of anaesthetized rats under stimulation of the anterior periamygdalar cortex (APC) and septal lateral nucleus (SLN). The dominating type of impulse responses to APC and SLN stimulation recorded correspondingly in 31.4 and 12.8% of cells was expressed in a short latency (10-30 ms) phasic activation. It has been found that the convergence of these inputs, revealed in 9.8% of cells, is unidirected according to the genotype of the reaction...

The authors propose an original surgical procedure for the treatment of the orbito-palpebral hemangiomas. Preoperative evaluation include a CT-scan of the orbito-palpebral regions as well as a selective arteriogram. Embolizing was performed after supra-selective cannulation of the feeding vessel. Access to the orbital contents is obtained by an intracranial, superior eyelid crease and lymbic exposure. Complete bone reconstruction and functional reconstruction of the eyelid lead to a highly aesthetic and functional result...

On the basis of the experiments on animals the author made an attempt to find out the place of the action of some psychotropic drugs on the central nervous system and to discover the changes, which occurred in the functional state of various cerebral structures. He used drugs Imupramine (Psychoforin) and Diazepan (Valium), administered localy in some structures of the lymbic system and reticular formation of the cat cerebrum, using stereotaxic technique. The evaluation of the occurred changes was made by the changes in the spontaneous and induced cerebral activity, using the method of double stimuli...

Some electrophysiological correlations of periodically exacerbating psychopathological manifestations in epilepsy are discussed. It was established that in phenomenon of a "forced normalization" of the EEG deep structures of the lymbic system may show active foci of epileptical bioelectrical activity. It is suggested that such pictures of bioelectrical activity in the different brain structures are formed as a result of dissociated inhibitory influences of the brain stem. The necessity of a stereoelectroencephalographic study in this group of patients is emphasized in order to assess the possibilities of a successful surgical operation...

The authors examined the beta-adrenergic structures in the mesencephalic formation (MSF) in view of establishing their role on the activity of MSF in view of establishing the in rols on the activity of MSF itself and the relationship of the same formation with the cerebral cortex and the lymbic system. It was established that beta-adrenergic blockers after their local application in MSF could inhibit its function. The data from the effect on the induced bioelectrical activity indicated also diminution in the functional activity of MSF...
