Improving the signal to noise ratio of our brain and body by Prof. A G Ramakrishnan

Location: MMCR

Time & Venue : 4:00PM, March 8th, 2019 (Friday) at MMCR (First floor, Electrical engineering department)

The talk will also convince you that conscious, deep breathing is an amazing cardiac exercise, that involves 17 spinal nerves and can recruit up to 83 muscles,Your relationship with breathing will transform after this talk. In any field or situation, we call something a “signal”, if it is desirable or useful and “noise”, if it is undesirable or not useful. In the context of the brain and/or body, therefore, anything that improves the health, efficiency and/or performance can be considered “signal” and something that causes disease, decay or reduction in efficiency, “noise”. A very recent study has shown that breathing modulates the circulation of cerebrospinal fluid (CSF) in the brain. This is a finding with far-reaching implications. Improved circulation of CSF in the brain results in the effective elimination of metabolic waste products such as beta-amyloid from the brain, thus reducing the risk of Alzheimer’s disease. Boosting CSF has been linked to improvement in cognitive function and reduction of cognitive concerns in the elderly.
Deep breathing also results in increased oxygen and reduced carbon-dioxide levels in the blood and consequently, reduced heart rate and pumping force of the heart due to the feedback is given by the chemoreceptors at the aorta and carotid artery. Thus, deep breathing basically increases the signal-to-noise ratio of the brain.

Prof. A G Ramakrishnan is a professor in department of Electrical Engineering, IISc.
