aIf you are familiar with this scene , you’ll know how time flies when you are having fun. Now scientists have thought a reason why this is the case. Scans have shown that patterns of activity in the brain change according to how we focus on a task. When we are bored , we concentr...
Radial basis function networks (RBFNs).The hidden layer in an RBFN applies a radial basis function to the input. These functions compute their output based on the distance between the input data and specific centers associated with each function. RBFNs are often used for function approximation, ...
题目To a chef,the sounds of lip smacking,slurping and sallwing are the highest form of fltery (恭维).But to someone with a certain type of misophonia (恐音症),these same sounds can be torturous.Brain scans are now helping scientists start to understand why. People with ...

CT and MRI scans can also be used to image soft tissue and bones. These alternatives are pricier and require anesthesia, but they provide more detailed images. They are the best options for imaging the brain and spinal cord. Dog Ultrasounds FAQs What does a dog ultrasound show? A dog ultr...
In the first experiment, researchers performed functional MRI scans (功能性磁共振成像扫描) of the brain and asked questions to 24 adults after eight hours of sleep and after a night with no sleep. When they were well rested, the participants scored well on a helping behavior test. But after...
If two students named each other, they were considered friends for the purposes of the study. Researchers used those responses to reconstruct the social network of the business school class. In the next phase of the study, 42 of the students agreed to lie in a functional MRI scanner while ...
