چکیده

We provide the first evidence that stochastic resonance within the human brain can enhance behavioral responses to weak sensory inputs. We asked subjects to adjust handgrip force to a slowly changing, subthreshold gray level signal presented to their right eye. Behavioral responses were optimized by presenting randomly changing gray levels separately to the left eye. The results indicate that observed behavioral stochastic resonance was mediated by neural activity within the human brain where the information from both eyes converges.

Pseudo-CT Generation from Magnetic Resonance Imaging by fuzzy look up table algorithm

Introduction: Despite growing interest in the use of magnetic resonance imaging (MRI) in the external radiotherapy design process (RT), Computer Tomography (CT) remains a gold standard and is regarded as a basic imaging modality in radiotherapy. MRI shows the high contrast in soft tissues without any radiation exposure to patients. As a result, MRI is used in functional tissue ...

Stochastic resonance effects reveal the neural mechanisms of transcranial magnetic stimulation.

Transcranial magnetic stimulation (TMS) is a popular method for studying causal relationships between neural activity and behavior. However, its mode of action remains controversial, and so far there is no framework to explain its wide range of facilitatory and inhibitory behavioral effects. While some theoretical accounts suggest that TMS suppresses neuronal processing, other competing account...

Two dogs with generalized seizures were evaluated. The dogs were diagnosed with traumatic intracranial hemorrhages based on the history, neurological examinations, and magnetic resonance imaging (MRI) of the brain. Treatment was started with oxygen, prednisolone and anticonvulsant agents. No further seizure activity was observed after treatment in both dogs, however cushing reflex was detected ...
