Clues to understand the potential effects of yoga on the brain
A clue to understand the potential effects of yoga on the brain is the increase of serum brain derived neurotrophic factor (BDNF). Physical exercise is associated with an increase of this neuromodulator that has a crucial role in ameliorating the function of the brain (1). This neurotrophin is a mediator of cognitive enhancement. It supports memory function through molecular and cellular mechanisms that help to strengthen communication between neurons (synapsis). This is relevant to the plastic changes that happen in the brain. The central nervous system is designed to perceive stimuli and to adapt to the environment in response to the information it receives. In these dynamic processes neuroplasticity of the brain plays a role. Neuroplasticity is what happens to the brain when it strengthens neural pathways and enhances the interactions between neurons to learn and gain knowledge in response to stimulation. BDNF is part of this process. Studies have sh...
