Microglia are a type of glial cell located throughout the brain and spinal cord of the central nervous system (CNS). [1] Microglia account for about 10–15% of cells found within the brain. [2] As the resident macrophage cells, they act as the first and main form of active immune defense in the CNS. [3]
[1] [2] The brain is an extremely complex system of heterogeneous tissues and consists of a diverse array of neurons and glial cells. This complexity has made studying the brain and understanding how it works a difficult task in neuroscience, especially when it comes to neurodevelopmental and neurodegenerative diseases.
In general, neuroglial cells are smaller than neurons. There are approximately 85 billion glia cells in the human brain, [8] about the same number as neurons. [8] Glial cells make up about half the total volume of the brain and spinal cord. [27] The glia to neuron-ratio varies from one part of the brain to another.

The MLR was first described by Shik and colleagues in 1966 when they observed that electrical stimulation of a region of the midbrain in decerebrate cats produced walking and running behavior on a treadmill. [3] Twenty-eight years later, Masdeu and colleagues described the presence of a MLR in humans. [4]
This forms threads that create tangles inside nerve cells, ultimately interfering with the way cells in the brain communicate. Most research has focused on early detection for beta-amyloid plaques ...
Botox is derived from botulinum toxin type A, a toxin that’s produced from the bacterium Clostridium botulinum. It just so happens to be the same bacterium that causes botulism, a rare condition ...
