The brain can be divided into three basic units: the forebrain, the midbrain, and the hindbrain. The hindbrain includes the upper part of the spinal cord, the brain stem, and a wrinkled ball of tissue called the cerebellum (1). The … Continue reading →

The human brain is extremely rich in sialic acids (9 carbon back bone acidic amino sugars). The predominant form of sialic acid in the mammalian brain is N-Acetylneuraminic acid (Neu5Ac), even in most mammals where other tissues can be rich … Continue reading →

Intracellular pH in the brain is maintained at approximately 7.2 [16]. This parameter is strongly regulated by active (ion pump transport) and passive (ion channel transport, intracellular buffer solution) mechanisms [16]. How does pH affect the brain? His studies suggest … Continue reading →

Citric acid does not produce electricity by itself. Rather, this weak acid turns into an electrolyte — an electrically conductive substance — when it’s dissolved in fluid. The charged ions of the electrolyte allow electricity to travel through the fluid. … Continue reading →
