It depends...
We have different schools and paradigms both in Psychology and Philosophy.
One of this is: our mind equals our brain. In this way you could think and reason in terms of our "psysical" universe and accordingly Neurology equals Psychology and Psychiatry.
But the psysical explanation of the mind (that equals the brain) does not explain other fenomena.
For example, a thought (something we cannot explain psysically) can move an arm (something physical). This means that we could have physical effects from not psysical causes...
Other examples are optical illusions and the stroboscopic movement. In the first case, our mind sees what psysically is not in the stimulus that the brain receives. In the second case, the mind perceives a movement where there is not psysical movement in the stimulus that the brain receives. In these cases, you could consider the results or effects like more than the simple sum of the single parts of the perceveid psysical universe concluding that mind and brain are not exactly the same thing...
Quite complicated... 😊
