How Does the Fight-or-flight Response Work?
Physiologist Edward Cannon described the fight-or-flight system as the stimulation of the sympathetic nervous system and the endocrine system after the body detects a threat. […]

Different people may respond to the same event in different ways. Some people may become stressed in situations while others don’t. Learning to control such stress can benefit one’s well-being. […]
Neurons in a healthy nervous system are incredibly fast in comparison to the hormones produced by the endocrine system glands. They both have varying mobility, but, surprisingly, can perform interchangeable roles. […]
Neurons play a big part in how we think and feel. In fact, a type of neuron specific to the brain may help explain why happiness is contagious and why it’s a good idea to watch more positive media and surround ourselves with happy people. […]
The nervous system controls reflex actions as well as both voluntary and involuntary actions. For these, it relies on the spinal cord and the peripheral nervous system, respectively. […]
Environmental factors and experiences bring about changes in the brain. While new connections are formed with experiences, old and unused connections are removed to make the brain faster and more efficient. […]
Different parts of the brain specialize in different tasks. Interestingly, recent research has found that the functions and structure of the brain can and do change. […]
The three major sections of the brain are the hindbrain, the midbrain, and the forebrain. They all perform different functions, such as directing basic survival processes, regulating our movements, and controlling our thoughts and emotions. […]
Breakthroughs in technology have allowed us to see how people’s brains respond in different situations and to different stimuli. Techniques like EEG, MRI, and fMRI show patterns of brain activity. […]
In the pursuit of happiness, there are many things one can do deliberately, such as spend money on experiences, be more charitable, and focus on building strong relationships. […]
