Glial cells and their role in the brain

Glial cells are cells nurse of the nervous system that play, so the main support
function of neurons, are active also in processing brain information in the body
...
(Baumann et al
...
They also physically isolate the neurons, forming the bloodbrain barrier (épendymocytes and type I astrocytes)
...


Type I astrocytes also provide the function of structural and metabolic function
...
They used to synchronize
synaptic activity, by varying the ion concentrations around neurons which changes the
electrical state and thus the responsiveness of these neurons
...

(Johansson et al
...
This is the sheath
that accelerates the transmission of nerve impulses in the axons
...

For example, this action changes the potentiation of the neuron but also develops their
ability to develop synapses
...
The means
by which these waves propagate is not yet clear, but the ATP seems very involved

Gap junctions between astrocytes could also intervene
...
Some even speak
of gliotransmitters
...
2001)

It is now known that glial cells can be transformed and are capable of generating
neurons operational, with the potential repair of altered neurons
...
(Katherine 2008)

The memory can be explained in terms of neurobiological (both in terms of cellular
network) by neuronal activity, but the role of astrocytes is still debated
...
This is due to the finding of the emergence
and proliferation of glial tissue replacing neurons after injury or trauma involving
neuronal damage
...
Only oligodendrocyte precursor cells
residing in the mature nervous system tissues preserved this peculiarity
