what happens in detail in the brain neuroscience when we meditate?

Meditation has been shown to produce changes in the brain, including:

Increased activity in the anterior cingulate cortex and the prefrontal cortex, which are involved in executive functions such as attention and self-control.

Decreased activity in the default mode network, a network of brain regions that is more active during mind-wandering and self-referential thinking.

Changes in the thickness of certain regions of the cortex, particularly in regions associated with attention and sensory processing.

Changes in the volume of certain brain structures, such as the amygdala, which is involved in the regulation of emotions.

Increased connectivity between brain regions, leading to improved communication between different parts of the brain.

Alterations in the patterns of brain waves, with increased alpha and theta waves seen in experienced meditators.

Increased production of brain-derived neurotrophic factor (BDNF), a protein that helps to support the survival and growth of neurons in the brain.

These changes are thought to be responsible for the various benefits of meditation, such as improved attention, reduced stress and anxiety, and enhanced well-being.
