The extent of peritumoral brain edema (PTBE) is one of the important prognostic factors in patients with meningioma.A 55-year-old female patient suffering from a progressive severe headache and mild left hemiparesis was referred to the Department of Neurosurgery, Rasool Akram Hospital (Tehran, Iran). The preoperative imaging revealed a 2×2 cm so...

Brain-inspired approaches can efficiently analyze the activities of biological neural networks and solve computationally hard problems with energy efficiencies unattainable von Neumann architectures, indicating a significant improvement in understanding neuronal communications functionalities. Here, we present brain-inspired multimodal signal processing system organic memristor arrays that pote...

Brain diseases threaten hundreds of thousands people over the world. Medical imaging techniques such as MRI and CT are employed for various brain disease studies. As artificial intelligence succeeded in image analysis, scientists intelligence, especially deep learning technologies, to assist The AI applications studies can be divided into two categories. first category is preprocessing, includi...

asterixis, firstly described in metabolic encephalopathies, may occur unilaterally in patients with various focal brain diseases. although hardly localizing, most reported cases have showed a contralateral thalamic pathology; but lesions in the medial frontal lobe, parietal lobe, brain stem, basal ganglia, insular lesions, may also cause unilateral asterixis. in this article, three cases of acu...
