A 2013 study from the University of Virginia found that the human brain is wired to connect so strongly with other humans that it experiences what other humans are experiencing even though it is not going through the same experience. This was shown when participants underwent fMRI brain scans. The correlation between self and friend was strong in the study. This is a psychological phenomenon as it affects a person's mind and their behavior.
Studying the nervous system means studying its two major systems: the central nervous system, which consists of the brain and spinal cord, and the cerebral cortex, which is involved in higher cognitive, emotional, sensory and motor functions. The peripheral nervous system is divided into two additional sub-systems. These sub systems are the somatic nervous system and the autonomic nervous system. The somatic nervous system has the primary function of regulating the actions of the skeletal muscles while the autonomic nervous system works to regulate involuntary activity, such as the heart rate or breathing.Learn more about Nerves
Afferent neurons carry signals to the brain and spinal cord as sensory data, and efferent neurons send signals from the brain to the muscles, glands and organs of the body in response to sensory input. The main cell bodies of afferent neurons are located near the brain and spinal column, which comprise the central nervous system.Full Answer >
