Dictionary
brain : the portion of the vertebrate central nervous system enclosed in the skull and continuous with the spinal cord through the foramen magnum that is composed of neurons and supporting and nutritive structures (as glia) and that integrates sensory information from inside and outside the body in controlling autonomic function (as heartbeat and respiration), in coordinating and directing correlated motor responses, and in the process of learning — Webster

Brain The brain is an organ that serves as the center of the nervous system in all vertebrate and most invertebrate animals. The brain is located in the head, usually close to the sensory organs for senses such as vision. The brain is the most complex organ in a vertebrate’s body. In a human, the cerebral cortex contains approximately 15–33 billion neurons, each connected by synapses to several thousand other neurons. These neurons communicate with one another by means of long protoplasmic fibers called axons, which carry trains of signal pulses called action potentials to distant parts of the brain or body targeting specific recipient cells. — Wikipedia

Nature Reviews Neuroscience - Issue - nature.com science feeds Nature Reviews Neuroscience is the leading review journal in the neurosciences. It publishes articles that review recent progress in brain and nervous system research. Topics range from molecular and cellular aspects of neuronal development and function to behavior, cognition and disorders of the nervous system. By commissioning the best authors to write on the timeliest issues, and following a rigorous peer-review process, the journal provides an unparalleled source of information and opinion for neuroscientists in academia, clinical research and industry. One of the unique features of Nature Reviews Neuroscience is its extraordinary breadth and depth of coverage. This very broad scope – from molecules to mind – captures the essence of modern neuroscience, and allows the journal to attract readers from all areas of this ever-expanding discipline.
- Mechanisms of node of Ranvier assemblyby Matthew N. Rasband on November 25, 2020 at 12:00 am
Nature Reviews Neuroscience, Published online: 25 November 2020; doi:10.1038/s41583-020-00406-8The formation of the nodes of Ranvier in myelinated axons involves a specific clustering of ion channels. In this Review, Rasband and Peles describe two independent, glia-directed mechanisms that converge on the axonal cytoskeleton to cluster and maintain nodal ion channels.
