The brain is, currently, seen as the home of the mind. There is some sort of connection between the mind and the brain, but there is not a way to gauge that connection with current science. There is no science of the consciousness as of yet. But there are connections between the brain and the mind that science has found so far. There is a common belief that the soul/mind is where our personality comes from, and things like our emotions and our memories.
There is definitely a connection between the personality and the brain. For example, an American railway foreman, Phineas Gage, had a drastic personality change when he suffered an injury to the frontal lobe in 1848. He had little to no intellectual change, only his personality became more violent. Many personality changes come from damage to the frontal lobe, temporal lobe and other changes can come from chemical derailments in the brain. During scans, there is evidence that parts of the brain are related to emotion. The brain and the mind are connected on some level, a level so complex, that humans cannot even begin to grasp what it is. If there is such a thing as the soul/mind as a separate entity from our physical person, I believe that it would be dependent on the brain. Since injuries to the brain can cause such drastic changes to us as people, there has to be a connection. The pineal gland in the brand is dubbed the “third eye” and has been called the seat of the soul. There are many parts to our brain that have connections to the spiritual experience of being a human. While the relationship between our physical self and our spiritual self has not been directly defined, there is evidence that they are both interconnected.
