If we are going to feel inspired to meditate regularly, we need to know what benefits our efforts can bring.
There is growing scientific evidence that meditation has a positive effect on our health and well-being, and meditation techniques are routinely used in the treatment of stress, depression and a wide range of medical conditions. In recent years there has been a rapid increase in the number of reputable scientific studies being undertaken into the beneficial effects of meditation on human well-being and on the neurological activity of the brain.
Here are a few sample links to ongoing scientific research that may be of interest.

The brain has the ability to change its structure and function – strengthening and expanding circuits that are frequently used, and weakening and shrinking those that are rarely engaged. This flexibility in the brain is what is called ‘neuroplasticity’, and explains why meditation can have a lasting effect on the way we process thoughts and emotions.
Some books on neuroplasticity:

Neuroscientist have discovered that meditation can stimulate significant increases in activity in several parts of the left prefrontal cortex—an area of the brain associated with positive emotions, such as happiness, enthusiasm, joy and self-control. Meditators also showed a decreased level of activity in the parts of the brain related to negative emotions, such as depression, self-centredness and a lack of happiness or satisfaction. Meditation produces a calming effect in the amygdala, the part of the brain that acts as a trigger for fear and anger.

Studies have shown that Mindfulness-Based Cognitive Therapy can halve the rate of relapse in people who have suffered two or more episodes of serious depression.
