Physiology and Signaling
The brain contains roughly 100 billion neurons, with each neuron forming connections with up to thousands of other neurons. These connections are called synapse. This mechanism comprise of various complex pathways, ion channels, receptors, proteins and junctions. Cell signaling and cell physiology have allowed studies of molecular processes in the context of the integrated behavior of cells and their organelles, and of tissues and organs, and whole organism.
The global CNS biomarker market was estimated at $1.7 billion in 2011 and nearly $2 billion in 2012. The market is projected to reach $5.1 billion by the end of the forecast period of 2012 to 2017, representing a compound annual growth rate (CAGR) of 20.7%.
