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.

Nature Reviews Neuroscience, Published online: 13 January 2022; doi:10.1038/s41583-021-00548-3Deciphering the mechanisms that cause encoded memories to be forgotten may help us to understand both adaptive forgetting and pathological memory loss. In this Perspective, Tomás Ryan and Paul Frankland propose that forgetting involves neuroplasticity that alters engram cells accessibility and is governed by changes in environmental predictability.

Nature Reviews Neuroscience, Published online: 07 January 2022; doi:10.1038/s41583-021-00555-4Crosstalk between the peripheral nervous system and the immune system coordinates responses to external and internal threats, including pathogens and tissue damage. Chiu and colleagues review our current understanding of the mechanisms by which sensory, sympathetic, parasympathetic and enteric neurons modulate immune cell function.

Nature Reviews Neuroscience, Published online: 04 January 2022; doi:10.1038/s41583-021-00544-7Ingestive and digestive processes are initiated and regulated by mechanosensory signals along the digestive tract. In this Review, Kim, Heo and Kim discuss recent discoveries of specific mechanoreceptors, contributing ion channels and well-defined circuits underlying gut mechanosensation, focusing on the oral and pharyngeal cavities, oesophagus, stomach and intestines.
