Sensory stimuli control dopamine in the brain

Regardless of whether we are sitting in a loud aeroplane or walking through a quiet forest clearing, how humans perceive their environment depends on the stimuli. This, in turn, affects our behaviour – sometimes consciously, ...

Neurons modulate the growth of blood vessels

A team of researchers at Karlsruhe Institute of Technology (KIT) shake at the foundations of a dogma of cell biology. By detailed series of experiments, they proved that blood vessel growth is modulated by neurons and not, ...

Neuron

A neuron (pronounced /ˈnjʊərɒn/ N(Y)OOR-on, also known as a neurone or nerve cell) is an excitable cell in the nervous system that processes and transmits information by electrochemical signalling. Neurons are the core components of the brain, the vertebrate spinal cord, the invertebrate ventral nerve cord, and the peripheral nerves. A number of specialized types of neurons exist: sensory neurons respond to touch, sound, light and numerous other stimuli affecting cells of the sensory organs that then send signals to the spinal cord and brain. Motor neurons receive signals from the brain and spinal cord and cause muscle contractions and affect glands. Interneurons connect neurons to other neurons within the same region of the brain or spinal cord. Neurons respond to stimuli, and communicate the presence of stimuli to the central nervous system, which processes that information and sends responses to other parts of the body for action. Neurons do not go through mitosis, and usually cannot be replaced after being destroyed, although astrocytes have been observed to turn into neurons as they are sometimes pluripotent.
