A case of Charles Bonnet syndrome in an elderly patient with occipital lobe lesion is described. Authors have highlighted the complex interplay of various neurobiologicat factors such as cortical blindness, structural brain lesion and epileptiform brain activity in the pathophysiology of this syndrome. The impact on the clinical presentation of brain changes on aging and those following cortica...

Traumatic brain injury is a major cause of mortality in developed countries. Cerebral parenchymal injury is evidenced by a significant percentage of patients. The most important structural lesion of the brain is the cerebral contusion, which is a complex and dynamic area, a result of the primary lesion and which is associated with ischemic and inflammatory phenomena that need to be known by the...

Figure 1. Brain perfusion emission tomography (Tc-exametazime; 740 MBq, 60 min after injection): transaxial slice (A) and selected views from 3D surface rendering reconstruction (B), showed a hot lesion outside the brain limits. Computed tomography (CT) of the head revealed a lytic lesion in the frontal right bone, that exactly corresponds to the hot spot seen on scintigraphy: brain (C) and bon...

The state-of-the-art deep learning methods have demonstrated impressive performance in segmentation tasks. However, the success of these depends on a large amount manually labeled masks, which are expensive and time-consuming to be collected. In this work, novel consistent perception generative adversarial network (CPGAN) is proposed for semi-supervised stroke lesion segmentation. CPGAN can red...

Glutamate is the most important excitatory neurotransmitter in the central nervous system which is involved in synaptic transmission, brain development, synaptic plasticity, learning, and memory. Normally, the enzymatic destruction of glutamate does not occur in the synaptic and extracellular space, but glutamate is removed through specific transporter proteins, leading to stabilization of glut...
