there's two ways to do that one of them is through neurons that reach out into the body and sense things and this is referred to as Inception right so as opposed to extra reception your your outward pointing senses these are the senses that monitor or your own body and and while we can consciously be aware of a lot of that information a lot of it is happening subconsciously like your breathing is happening automatically most of the time without you thinking about it and that depends upon sensors about your blood chemistry and the state of your lungs and a number of other things that are regulating that process and it's all happening in the brain usually below the level of your conscious attention In addition to the neural signals there is also a whole realm of hormonal or diffusible immune signals and what these are is that these are chemicals that are released into the bloodstream and that move throughout the body and that can uh uh activate neurons in the brain or in other parts of the nervous system to produce changes in uh in mental in mental function
