Glia are grouped into macroglia – astrocytes, ependymal cells, and oligodendrocytes, and much smaller microglia which are the macrophages of the central nervous system. Astrocytes are seen to be capable of communication with neurons involving a signalling process similar to neurotransmission called gliotransmission .

Astrocytes are a sub-type of glial cells in the central nervous system. They are also known as astrocytic glial cells.
This slow process, referred to as consolidation, allows emotions to influence the way the memory is stored. [7] The amygdala is involved in memory consolidation, which is the process of transferring information that is currently in working memory into ones long-term memory. This process is also known as memory modulation. [7]
Evidence for the role of astrocytes in the integration and processing of synaptic integration presents itself in a number of ways: Astrocytes are excitable cells: In response to stimuli from any of the three components of the tripartite synapse, astrocytes are capable of producing transient changes in their intracellular calcium concentrations through release of calcium stores from the ...
Astrocytes are the largest of the glial cells. They are stellate cells with many processes radiating from their cell bodies. Some of these processes end as perivascular endfeet on capillary walls. [42] The glia limitans of the cortex is made up of astrocyte endfeet processes that serve in part to contain the cells of the brain. [12]
These cells (and other neuroglia including astrocytes) are distributed in large non-overlapping regions throughout the CNS. [5] [6] Microglia are key cells in overall brain maintenance – they are constantly scavenging the CNS for plaques, damaged or unnecessary neurons and synapses, and infectious agents. [7]
Philip Beesley's Astrocyte aims to show that architecture can be more than just ornamental. Built from acrylic, mylar, sensors, custom glasswork, 3D-printed lights and using AI, chemistry and a ...
In cellular neuroscience, the soma (pl.: somata or somas; from Greek σῶμα (sôma) 'body'), neurocyton, or cell body is the bulbous, non-process portion of a neuron or other brain cell type, containing the cell nucleus.
