  2. Dicamba - Wikipedia

    en.wikipedia.org/wiki/Dicamba

    Dicamba is toxic to conifer species but is in general less toxic to grasses. [2] Dicamba is a synthetic auxin that functions by increasing plant growth rate, leading to senescence and cell death. [2] [11] The growth regulating properties of dicamba were first discovered by Zimmerman and Hitchcock in 1942. [12]

  3. Neurobiological effects of physical exercise - Wikipedia

    en.wikipedia.org/wiki/Neurobiological_effects_of...

    Neuroplasticity is the process by which neurons adapt to a disturbance over time, and most often occurs in response to repeated exposure to stimuli. [27] Aerobic exercise increases the production of neurotrophic factors [note 1] (e.g., BDNF, IGF-1, VEGF) which mediate improvements in cognitive functions and various forms of memory by promoting blood vessel formation in the brain, adult ...

  4. Blood–brain barrier - Wikipedia

    en.wikipedia.org/wiki/Bloodbrain_barrier

    The bloodbrain barrier (BBB) is a highly selective semipermeable border of endothelial cells that regulates the transfer of solutes and chemicals between the circulatory system and the central nervous system, thus protecting the brain from harmful or unwanted substances in the blood. [1]

  5. Neurotoxin - Wikipedia

    en.wikipedia.org/wiki/Neurotoxin

    The nervous tissue found in the brain, spinal cord, and periphery comprises an extraordinarily complex biological system that largely defines many of the unique traits of individuals. As with any highly complex system, however, even small perturbations to its environment can lead to significant functional disruptions.

  6. Cerebral circulation - Wikipedia

    en.wikipedia.org/wiki/Cerebral_circulation

    Cerebral circulation is the movement of blood through a network of cerebral arteries and veins supplying the brain. The rate of cerebral blood flow in an adult human is typically 750 milliliters per minute, or about 15% of cardiac output. Arteries deliver oxygenated blood, glucose and other nutrients to the brain.

  7. Neurotoxicity - Wikipedia

    en.wikipedia.org/wiki/Neurotoxicity

    Neurotoxicity is a form of toxicity in which a biological, chemical, or physical agent produces an adverse effect on the structure or function of the central and/or peripheral nervous system. [1] It occurs when exposure to a substance – specifically, a neurotoxin or neurotoxicant – alters the normal activity of the nervous system in such a ...

  8. Cerebral autoregulation - Wikipedia

    en.wikipedia.org/wiki/Cerebral_autoregulation

    By means of cerebral autoregulation, the body is able to deliver sufficient blood containing oxygen and nutrients to the brain tissue for this metabolic need, and remove CO 2 and other waste products. Cerebral autoregulation refers to the physiological mechanisms that maintain blood flow at an appropriate level during changes in blood pressure ...

  9. Neurovascular unit - Wikipedia

    en.wikipedia.org/wiki/Neurovascular_unit

    The cells of the neurovascular unit also make up the bloodbrain barrier (BBB), which plays an important role in maintaining the microenvironment of the brain. [11] In addition to regulating the exit and entrance of blood, the bloodbrain barrier also filters toxins that may cause inflammation, injury, and disease. [12]
