By following pranayama for few weeks, the bulbopontine
complex is adjusted to a new pattern of breathing which is slower than its basal rhythm causing decrease in respiratory rate.
 We believe that during daily practice of pranayama the basic activity of the bulbopontine
complex is modified in such a way as to slow down its rhythm.
Brain magnetic resonance imaging (MRI) showed T1-low and T2-high bulbopontine
and cerebellar lesions around the fourth ventricle (Figure).
