Microglia are a type of glial cell that are the resident macrophages of the brain, and thus act as the first and main form of active immune defense in the central nervous system (CNS). Microglia constitute 20% of the total glial cell population within the brain. Unlike astrocytes, individual microglia are distributed in large non-overlapping regions throughout the brain and spinal cord. Microglia are constantly moving and analyzing the CNS for damaged neurons, plaques, and infectious agents. The brain and spinal cord are considered “immune privileged” organs in that they are separated from the rest of the body by a series of endothelial cells known as the blood-brain barrier, which prevents most infections from reaching the vulnerable nervous tissue. In the case where infectious agents are directly introduced to the brain or cross the blood-brain barrier, microglial cells must react quickly to increase inflammation and destroy the infectious agents before they damage the sensitive neural tissue. Due to the unavailability of antibodies from the rest of the body (few antibodies cross the blood brain barrier due to their large size), microglia must be able to recognize foreign bodies, swallow them, and act as antigen-presenting cells activating T-cells. Since this process must be done quickly to prevent potentially fatal damage, microglia are extremely sensitive to even small pathological changes in the CNS. They achieve this sensitivity in part by having unique potassium channels that respond to even small changes in extracellular potassium.
There is a peculiar intangibility to space, as well. We cannot pick it up and bring it to the laboratory. Like time, space is neither physical nor fundamentally real in our view. Rather, it is a mode of interpretation and understanding. It is part of an animal’s mental software that molds sensations into multidimensional objects.
Most of us still think like Newton, regarding space as sort of a vast container that has no walls. But our notion of space is false. Shall we count the ways?
1. Distances between objects mutate depending on conditions like gravity and velocity, as described by Einstein’s relativity, so that there is no absolute distance between anything and anything else.
2. Empty space, as described by quantum mechanics, is in fact not empty but full of potential particles and fields.
3. Quantum theory even casts doubt on the notion that distant objects are truly separated, since entangled particles can act in unison even if separated by the width of a galaxy.
An Unstable Emphathy is a reactive environment constantly remediated in real-time by the mind activity of two players.
At the beginning of the game two participants are selected from the audience; then some electroencephalographic (EEG) electrodes are mounted on the head of two players. Their Alpha brainwave (8-10 cicles/second) is measured in amplitude in order to assess the mental state and the level of relaxation and concentration of the two participants, while the players’ brain activity is rendered in real time as visuals on the big screen behind them and as spatialized sounds surrounding the environment.
