How the heart affects our perception

Brain and heart constantly communicate. For example, signals from the brain make sure that the heart beats faster when we encounter a dangerous situation. The heart slows down when we relax. Interestingly, vice versa – even though the underlying mechanisms are unclear, the heartbeat also affects the brain. It has now been identified by researchers at the Max Planck Institute for Human Cognitive and Brain Sciences (MPI CBS) in Leipzig and Berlin School of Mind & Brain that two mechanisms underpinning how the heart influences our perception, the brain, and how these mechanisms differ between individuals.

Stroke: The Second Time That The System Fails

After a stroke, there is an increased risk of suffering a second one. If areas in the left hemisphere were affected during the first attack, language is often impaired. In order to maintain this capability, the brain usually briefly drives up the counterparts on the right side. But what happens after a second attack? Medical researchers have now found an answer by using virtual lesions.

Jymmin: How a combination of exercise and music helps us feel less pain

Pain is essential for survival. However, it could also slow the progress of rehabilitation, or in its chronic form could become a distinct disorder. How strongly we feel it, among other factors, depends on our individual pain threshold. Scientists at the Max Planck Institute for Human Cognitive and Brain Sciences (MPI CBS) in Leipzig discovered that a new fitness method they developed increases our pain threshold and makes us less sensitive towards physical discomfort: Jymmin interacts with everyday gym equipment to produce music while exercising.
