The human brain uses transitional probabilities of sound events for forming predictions about the acoustic environment
Predicting future events is essential in our ever-changing environment. For example, when we hear a siren sound while driving, we need to form predictions about the course of its loudness in order to decide whether to pull
Immune cells of the brain called microglia, appear to have been adapted to their vulnerable environment. They react less destructive to danger signals than their counterparts in the blood. Microglia are the resident macrophages of the central
In brain infarction or traumatic injuries of the brain an immediate admission to a neurosurgical / neurological center can be life saving. With brain hemorrhages caused by a ruptured aneurysm the situation is not as clear. First
The chronic inflammatory disease lupus can involve the brain, including increasing stroke risk for reasons which are not fully understood. Cerebral small vessel disease (SVD) is a disease of the blood vessels in the brain that can
Study led by the University of Bonn elucidated a previously unknown possible cause of dementia. A study led by the University of Bonn opens a new perspective with regard to the development of dementia. The scientists blocked
Abnormal structural changes measured on cortical surfaces are important biomarkers for Alzheimer’s disease (AD). In brain imaging research, landmark curves are usually delineated on cortical surfaces to represent significant sulcus and gyrus patterns. Landmark curves are widely
Polycystic ovary syndrome (PCOS), the most common endocrine disorder of women in childbearing age, is characterized by hyperandrogenism, oligo-anovulation and polycystic ovaries in ultrasound. Obesity, a global epidemic, generally accompanies PCOS; but the link between these two
The brain is made up of four major types of brain cells. Neurons, oligodendrocytes, microglia and astrocytes. Neurons (nerve cells) are specialised cells that process and carry ‘messages’ through electrical signals. Oligodendrocytes are cells which are wrapped
Staying physically active is one of the most beneficial things that a person can do for maintaining whole-body health. It is well understood that physical activity is important for building muscle, improving cardiovascular health, and boosting metabolism.
Epileptic encephalopathies in children: Animal models may change the word “catastrophic” to “hopeful”
Seizures are a sign of brain dysfunction caused by abnormal, hyperexcitable brain circuits. Clinical seizures range from brief staring spells to massive whole – body convulsions. The developing brain is especially prone to seizures and seizure-related brain
Neuroscientists’ discovery of grid cells, popularly known as the brain’s GPS, was hailed as a major discovery. But new results suggest the system is more complicated than anyone had guessed. Just like a driver in a car,
Rewarding ( pleasurable ) and aversive events give us dissimilar perceptions, which powerfully shape our decisions and therefore behavioral outcomes. In fact, chemical changes, which take place in our brain, are very different under these opposite circumstances.
