Several explanations have been proposed to account for the mechanisms of neuroglial interactions involved in neural plasticity. We review experimental results addressing plastic nonlinear interactions between glial membranes and synaptic terminals. These results indicate the necessity of elaborating on a model based on the dynamics of hydroionic waves within the neuropil. These waves have been ...

In patients with posttraumatic stress disorder (PTSD), we found evidence of altered systemic cerebral functioning by mapping generators of slow waves produced within circumscribed brain regions. Such focal activities have been associated with lesioned neural circuitry in neurological disorders and more recently also in mental illness. Using magnetoencephalographic (MEG-based) source imaging, we...

The brain tumor is abnormal growth of cells inside skull which causes damage of the other cells necessary for functioning human brain. The brain tumor detection is challenging task due to complex structure of human brain. MRI images generated from MRI scanners using strong magnetic fields and radio waves to form images of the body which helps for medical diagnosis. This paper gives the overview...

all people have experience about anxiety in their lives and it is natural when facing with reactional threatening situations. but chronic and intense feeling is unusual in absence of clear cause. anxiety includes uncertainty, helplessness and physiological arousal feelings. generally anxiety is a diffuse, very unpleasant and often vague concern feeling. clinical studies of war veterans over the...

this study briefly reviews the heart abnormalities in diverse intracranial pathologies, including strokes, spontaneous and traumatic subarachnoid hemorrhage and intracranial hemorrhage, and presents the results of a one-year prospective study of heart abnormalities in patients with moderate to severe head injuries and subarachnoid hemorrhage. different abnormalities such as: qt -interval, t -wa...

Theta waves in the amygdala are known to be synchronized with theta waves in the hippocampus. Synchronization between amygdala and hippocampal theta waves is considered important for neuronal communication between these regions during the memory-retrieval process. These theta waves are also observed during rapid eye movement (REM) sleep. However, few studies have examined the mechanisms and fun...

In this work, we explore the possibility of decoding Imagined Speech brain waves using machine learning techniques. We propose a covariance matrix Electroencephalogram channels as input features, projection to tangent space matrices for obtaining vectors from matrices, principal component analysis dimension reduction vectors, an artificial feed-forward neural network classification model and bo...
