Work beginning in the 1970s determined that astroglia (astrocytes in culture) exhibit a wide variety of neurotransmitter receptors that regulate both second messenger systems and ion channels. These findings suggested that astrocytes i

The Markowitz Model with a Risk-Free Assetns, and describes the Markowitz optimization problem in this setting. A criterion for portfolio efficiency and an explicit formula for an efficient portfolio with the given risk tolerance are derived and discussed.
