How does the nervous system affect human behavior

It increases our heart rate, which in turn increases the heart output of blood flow to our muscles.It guides everyday activities such as waking up;Stimulating certain regions of the temporal lobes produces an intense feeling of fear or dread;The two systems which are considered here are the reticular activating system and the limbic system.The challenge to neuroscience then, is to explain, in physical and chemical terms, how the nervous system marshalls its signaling units to direct behavior.

Numbness, tingling, weakness, or inability to move a part or all of one side of the body (paralysis).The nervous system controls the way a person learns, thinks, feels, eats, the beating of the heart, digestion, and the stress that people feel.The more complex the behaviour, the greater is the involvement of the nervous system.Stimulating nearby regions produces a feeling of isolation and loneliness, other regions a feeling of disgust, and yet others intense sorrow, depression, anxiety, ecstasy, and, occasionally, guilt.The real magnitude of this challenge can perhaps be best judged by considering the structural and functional complexity of the human brain and the bewildering complexity of human behavior.

It causes our pupils to constrict so that we can focus on a specific threat.For example, move your arm.1 these functions include metabolism, reproduction, emotion.How does the nervous system control human behavior?The nervous and endocrine systems.

Correspondingly, it is also found that the structure and organisation of the nervous system becomes increasingly complex.
