The Brain and the Nervous System

The brain is the most complicated organ in the human body. It gives us our personality and our feelings, and is responsible for consciousness, self-awareness, time perception, and memory functions.

 

The nervous system receives and stores information, processes and interprets sensory information, and controls bodily functions.

The brain, the spinal cord, and the peripheral nerves within a human being contain 100 billion nerve cells, called neurons, of at least 10,000 different types. Studies of the molecular energy mechanisms that control specialization have revealed that neurons are not controlled by a single regulatory gene, but by a sequential, combined effect of many regulatory genes and their unique interaction with the brain’s neural pathways.
Research into the nervous system has made great strides in recent years.

It has been passably well demonstrated today how neurotransmitters in various parts of the brain contribute to stimulating or impeding signals from being transmitted further. The new molecular biology, and new imaging techniques and surgical methods, have radically increased the opportunities to understand and fix injuries and diseases in the nervous system.

Holding a mug, feeling the ground as you walk, petting your furry friend, or hugging your child, all of these touch sensations start with deformation of the skin that the nervous system must process to serve physiological, emotional and social goals.

Young Survivor Unit - YoSU

Our research aims to better understand the development of children who have been seriously ill early in life. Furthermore, to develop and study interventions that, in the long term, increase the children's functioning in everyday life.

Discovery about pain signalling may contribute to better treatment

LiU researchers have pinpointed the exact location of a specific protein fine-tuning the strength of pain signals. The knowledge can be used to develop drugs for chronic pain that are more effective and have fewer side effects.

Our sense of touch consists of 16 unique types of nerve cells

No less than 16 different types of nerve cells have been identified by scientists in a new study on the human sense of touch. Comparisons between humans, mice and macaques show both similarities and significant differences.

Existing drug can repair ion channel linked to epilepsy

Mutated variants of a particular ion channel cause difficult-to-treat epilepsy. A study published in the journal Nature now shows that a commonly used anaesthetic drug, propofol, can restore the function of this ion channel.
