Cognitive functions depend on all parts of the brain working properly; when these systems become disrupted, thinking can be affected. That's a rather long and winding examination of how thoughts influence what happens in the brain and in the body.
Justifiably so because there is still so much that is unknown when it comes to the brain. Indeed, if scientists had completely mapped out the processes of the brain, it's likely that they would be building supercomputers that could replicate the brain.
There will still be some who will argue that thoughts are entities separate from the body and that to describe how thoughts have a physical influence is absurd. While it's true that there is a lot we still don't understand about the mind, body, universe, etc.
This is the basis of many forms of talk therapy , such as cognitive-behavioral therapy. And this is a good thing—because it means that when you make the effort to change your thinking, you are also doing something that can have a positive impact on your brain and your body.
And, that effect can be a lasting change, particularly if you are blazing new neural pathways that have positive outcomes. Ever wonder what your personality type means?

Two greetings -- "hola" and "ciao" -- made the historic trip from India to France, where they were received and spoken by a researcher who was blindfolded and equipped with earplugs.
The scientists wanted to ensure that the receiver knew what his colleague 5, miles away was thinking because of the brain-to-brain transmission, not because of some other cue. The scientists wanted to prove, even with technology that will likely seem arcane in the near future, that it's possible for two human brains to communicate with each other directly, Alvaro Pascual-Leone of Beth Israel Deaconess Medical Center and Harvard Medical School, co-author of the study, said in a telephone interview.
Think Again. Brain to brain transmission is a hot topic among scientists around the world, and last year researchers at the University of Washington claimed to be the first to carry it off when a student on one side of the campus moved a finger while a colleague thought about the command on the other side of the campus.
But the breakthroughs also include a warning. This should be very valuable for medical applications, especially for patients with communication problems, but it could also be a source of devastating misuse. Does it pave the way for humans to read the minds of others, even without their consent?
You can see from these studies that our memories of previous experiences play a major role when we think about the future and make decisions. Maybe we evolved to have memories not only so we can dwell on the past, but also to help us to predict the future and to make better decisions in the present.
Many scientists now believe that the hippocampus has a role in linking together different parts of an experience as well as different related experiences.
When you remember your first day in school, you probably think about the appearance of the school, the people who were around, how you felt, etc.
These fragments of experience are bound together to create the whole memory with the help of your hippocampus. In a similar way, when you imagine your first day at college, you can remember and put together pieces of your past experiences to create a new image in your mind of a situation you have not yet experienced.
This mental ability to travel into the past and future is especially useful when making decisions. By remembering past experiences or by combining memories to form new situations in our minds, the hippocampus with the help of other brain regions can provide potential options for the brain to try out. Just like rats navigating a maze, we too can use our memories to make better decisions. When you are at a crossroads, whether having to decide which party to go to, or which high-school to attend, you can imagine each choice, and this mental simulation can help you evaluate how it would feel and how each option might help you to achieve whatever goals you have.
When we think about memory, we usually think about the past. Indeed, for more than a century, memory researchers focused on how people and animals store and recall past experiences and which brain structures support those functions. More recent research suggests a different view of memory. Recent findings show that the hippocampus—a brain region responsible for memory—is active when people imagine future events.
Additionally, in patients with amnesia, damage to the hippocampus impairs the ability to imagine the future. Together, these findings suggest that the hippocampus and its connections to other brain regions build upon past experiences to make predictions about future events.
