Every year, many people lose their lives in road traffic accidents while driving vehicles throughout the world. Providing secure driving conditions highly reduces road traffic accidents and their associated death rates. Fatigue and drowsiness are two major causes of death in these accidents; therefore, early detection of driver drowsiness can greatly reduce such accidents. Results of NTSB inves...

background: carbon monoxide (co) poisoning may lead to hypoxic/anoxic injury and eventually ischemic encephalopathy. magnetic resonance imaging (mri) has a well-recognized role in assessment of the severity of brain damage caused by co poisoning. in this study, we aimed to present and analyze the structural abnormalities in the brain mri and especially in diffusion weighted mri (dwi) images in ...

Detection and monitoring of neural signals is a fast-advancing area research expected to impact broad range advanced applications, from healthcare brain–machine even brain-to-brain communications. Two-dimensional (2D) layered materials, such as graphene, MXenes, transition metal dichalcogenides, could lead the development superior ultrathin thin-film electrodes for interfaces thanks their atomi...

Reasonably recent experiments show that unhappiness is strongly correlated with the excessive interaction between two parts of brain—amygdala and hippocampus. At first glance, in situations when outside signals are positive, additional brain get from different sensors should only reinforce positive feeling. In this paper, we provide a simple explanation why, instead expected reinforcement, obse...

Brain Computer Interface is a technique which allows people to interact with machines independent of muscles. Brain Computer Interface record the electrical signals from the brain and convert the recorded signals into corresponding control signals with the help of specialized computer. The main purpose of Brain Computer Interface is to enable the paralyzed people to communicate with their envir...

We performed dye-enhanced imaging of mouse brain microvessels using spectral focusing coherent anti-Stokes Raman scattering (SF-CARS) microscopy. The resonant signals from C-H stretching in forward CARS usually show high background intensity in tissues, which makes CARS imaging of microvessels difficult. In this study, epi-detection of back-scattered SF-CARS signals showed a negligible backgrou...

UNLABELLED Objective, Approach. A growing number of prototypes for diagnosing and treating neurological and psychiatric diseases are predicated on access to high-quality brain signals, which typically requires surgically opening the skull. Where endovascular navigation previously transformed the treatment of cerebral vascular malformations, we now show that it can provide access to brain signal...

Background: Early diagnosis of patients in the early stages of Alzheimer's, known as mild cognitive impairment, is of great importance in the treatment of this disease. If a patient can be diagnosed at this stage, it is possible to treat or delay Alzheimer's disease. Resting-state functional magnetic resonance imaging (fMRI) is very common in the process of diagnosing Alzheimer's disease. In th...

wet ag/agcl electrodes, although very popular in clinical diagnosis, are not appropriate for expanding applications of wearable biopotential recording systems which are used repetitively and for a long time. here, the development of a low‑cost and low‑noise active dry electrode is presented. the performance of the new electrodes was assessed for recording electrocardiogram (ecg) and electroence...
