Explanation:

Their plasma membrane is also made up of two layers of phospholipids and the proteins are embedded in it. Therefore, the plasma membrane of neurons is a semipermeable membrane as charged and polar substances can not cross its nonpolar core made up of the hydrophobic tails of the phospholipids.
