Final answer:
Option (1), Meditation has been shown to increase connections in the brain, enhance blood flow, oxygen availability, and leads to the growth of new neurons and neuronal pathways, similar to the effects of physical exercise.
Step-by-step explanation:
Regular meditation has been empirically shown to increase connections in the brain. Through consistent meditation practice, such as sitting comfortably, maintaining a quiet environment, and focusing on a mantra, individuals can experience an increase in blood flow and oxygen availability to the brain. This, in turn, can lead to the growth of new brain cells and the formation of new neuronal pathways.
Moreover, meditation can also raise levels of neurotransmitters like serotonin, which enhance memory retention, information processing, and cognition. These benefits are akin to those yielded by physical exercise, which also supports enhanced brain function.
