The S-100β levels are associated with a variety of acute disorders and other chronic diseases, such as head injury, stroke, metastatic melanoma, cardiac surgery, bone fractures, burns and contusions. The serum S-100β levels seem to increase with the volume of tissue damage. The higher serum S-100β levels have been observed after brain damage or stroke. A number of studies have evidenced the clinical value of S-100β in the diagnosis and prognosis of stroke while the S-100β marker is elevated in the peripheral blood during the acute phase of stroke...

Epilepsy is a complex neurological disease characterized by spontaneous episodes of abnormal, simultaneous firing of a neuronal population and disturbances of consciousness (so-called seizures) of unknown cause. Antiepileptic drugs are only symptomatic treatment, and there is a strong demand for the search of an alternative treatment of epilepsy. For this purpose, animal models of epilepsy are an important prerequisite. There are various animal models with chronic brain dysfunctions thought to reflect the processes underlying human epilepsy...

PURPOSE OF THE STUDY: Individuals with heart failure (HF) have a high frequency of sleep problems. Patients with HF present with structural brain changes different from normal aging including reductions in brain volume, increases in white matter hyperintensity (WMH), and reduced cerebral blood flow. These structural changes in the brain may explain the pathophysiology of sleep and daytime problems. The objective of this study was to determine whether multimodal imaging data are related to self-reported sleep problems and daytime sleepiness in older adults with HF...

Many particularities concerning interhemispheric differences still need to be explored and unveiled. Functional and anatomical differential features found between left and right brain sides are best known as asymmetries and are consequence of the unilateral neuronal recruitment or predominance that is set to organize some function. The outflow from different neural pathways involved in the autonomic control of the cardiovascular system may route through asymmetrically relayed efferences (ipsilateral/lateralized and/or contralateral)...

Neurological diseases and injuries to the nervous system may cause inadvertent damage to neuronal and synaptic structures. Such phenomenon would catastrophically accumulate, leading to the development of neurological and neurodegenerative disorders which might affect memory, cognition, and motoric functions. The body has various negative feedback systems which are able to induce beneficial neuroplastic changes in mediating some neuronal damage, however, such efforts are often not enough to ameliorate the derogatory changes...

Patients with epilepsy have a significantly higher risk of death than the general population. Sudden unexpected death in epilepsy (SUDEP) is the leading cause of sudden death among patients with epilepsy. Despite on-going research, there are still deficits in our knowledge about the mechanisms, genetic factors, and prevention of SUDEP. Current evidence suggests that cardiac arrhythmias, respiratory dysfunction, and brainstem arousal system dysfunction are the major mechanisms of SUDEP, and animal models support the role of neurotransmitters, especially serotonin and adenosine, in pathophysiology of SUDEP...

It is estimated that 109 bits/s information are processed in the human brain. The transmission of this huge amount of information requires all connections in the brain to be highly accurate and have order. The current study attempted to present a new aspect of order and proportion in the ultra-structure of the human brain and to calculate the degree of neural interdependence between the two hemispheres. In this model, intensity of interdependence of the brain to hemispheres is estimated to be equal to the mathematical proportion of number of neurons in cerebral cortex divided by 2 (number of hemispheres), divided by number of nerve fibers in the human corpus callosum...

PURPOSE: Amyloid beta (Aβ) is known to contribute to the pathophysiology of retinal neurodegenerative diseases such as glaucoma. Effects of intravitreal Aβ(1-42) on retinal and optic nerve morphology in animal models have widely been studied but not those of Aβ(1-40). Hence, we evaluated the time- and dose-related effects of intravitreal Aβ(1-40) on retinal and optic nerve morphology. Since oxidative stress and brain derived neurotrophic factor (BDNF) are associated with Aβ-induced neuronal damage, we also studied dose and time-related effects of Aβ(1-40) on retinal oxidative stress and BDNF levels...

The persistent primitive hypoglossal artery (PPHA) is the second most common persistent carotid-vertebrobasilar anastomosis. We present a rare case of an 82-year-old woman who diagnosed as acute cerebral infarction three times in both the anterior and posterior circulation territories with a right-sided PPHA and ipsilateral carotid artery dissection (CAD). Microembolus monitoring results suggested that microembolic caused by CAD associated with PPHA should be recognized as a possible cause of multiple infarctions in both the anterior and posterior circulation territories...
