Abstract

The dynamics of calcium ions bound within intracellular membranes (Ca2+b), changes of redox--state and bioelectrical activity were studies in vital brain preparation after kainic acid (KA) application either to the micro--zones iontophoretically or to the whole surface of the preparation. The Ca2+b dynamics depended on KA dose and included release of Ca2+b as well as bounding of calcium attracted from extracellular space. The early period of the reaction consisted of an increased intracellular reduction equivalents and a release of Ca2+b. Theme correlating processes were followed by "seizure" activity specific for the KA effect. The calcium free bounding effect started to prevail with increasing KA dose.

Astrocytes

Astrocytes are glial cells that support the blood-brain barrier, facilitate neurotransmission, provide nutrients to neurons, and help repair damaged nervous tissues. Here is the latest research.
