  2. Reticular formation - Wikipedia

    en.wikipedia.org/wiki/Reticular_formation

    The ascending reticular activating system (ARAS), also known as the extrathalamic control modulatory system or simply the reticular activating system (RAS), is a set of connected nuclei in the brains of vertebrates that is responsible for regulating wakefulness and sleep-wake transitions. The ARAS is in the midbrain reticular formation. [12]

  3. Thalamic reticular nucleus - Wikipedia

    en.wikipedia.org/wiki/Thalamic_reticular_nucleus

    The thalamic reticular nucleus is part of the ventral thalamus that forms a capsule around the thalamus laterally. However, recent evidence from mice and fish question this statement and define it as a dorsal thalamic structure.

  4. Reticuloendothelial system - Wikipedia

    en.wikipedia.org/wiki/Reticuloendothelial_system

    In anatomy the term reticuloendothelial system (abbreviated RES), often associated nowadays with the mononuclear phagocyte system (MPS), was employed by the beginning of the 20th century to denote a system of specialised cells that effectively clear colloidal vital stains (so called because they stain living cells) from the blood circulation.

  5. Thalamus - Wikipedia

    en.wikipedia.org/wiki/Thalamus

    Many different functions are linked to various regions of the thalamus. This is the case for many of the sensory systems (except for the olfactory system), such as the auditory, somatic, visceral, gustatory and visual systems where localized lesions provoke specific sensory deficits. A major role of the thalamus is support of motor and language ...

  6. Reticular cell - Wikipedia

    en.wikipedia.org/wiki/Reticular_cell

    A reticular cell is a type of fibroblast that synthesizes collagen alpha-1(III) and uses it to produce extracellular reticular fibers.Reticular cells provide structural support, since they produce and maintain the thin networks of fibers that are a framework for most lymphoid organs.

  7. JAK-STAT signaling pathway - Wikipedia

    en.wikipedia.org/wiki/JAK-STAT_signaling_pathway

    The pathway communicates information from chemical signals outside of a cell to the cell nucleus, resulting in the activation of genes through the process of transcription. There are three key parts of JAK-STAT signalling: Janus kinases (JAKs), signal transducer and activator of transcription proteins (STATs), and receptors (which bind the ...

    en.wikipedia.org/wiki/Activating_function

    The activating function is a mathematical formalism that is used to approximate the influence of an extracellular field on an axon or neurons. [1] [2] [3] [4] [5] [6 ...
