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.

How the nervous system distinguishes social touch

Two types of neurons in the skin may be particularly important for how the brain interprets social contact between people. Knowledge of how the nervous system processes social touch is important in order to develop ways to restore sensation.

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.
