Neuroscience Perspective
Scientists have long been interested in the relationship between our psychological ii our biological nature, particularly our brains. Spanish scientist Santiago Ramon y Cajal identified neurons-the cells that make up the brain and nervous system- in the early 1900s. His view that the brain was made up of a network of interacting neu'ct the foundation for our modern understanding of the role of the brain in psychology.
Psyhologists who approach the science from the neuroscience perspective are in- me structures of the brain that play roles in emotion, reasoning, speaking, and logical processes. They seek to determine the extent to which our psychologicharacteristics, such as intelligence and emotional stability, are influenced by heredity. Its study the chemical substances that carry messages in the nervous system from one neuron to another, and they examine how some drugs, such as cocaine and maridle action of these important brain chemicals. Similarly, neuroscientists conduct experiments on the role of hormones in the regulation of behavior.
Enormous progress has been made in unraveling the functions of the nervous system, the hormonal systems, but understanding the connection between the brain and problem that dwarfs any other problem facing science in its scale. The comlexity of the brain alone is almost too staggering to comprehend. Its 100 billion neurons form more than 100 trillion connections with other neurons. Since each of these connections can be either active or inactive at any moment in time, that means there arefar more possible states of a single human brain than the estimated total number of all of the electrons and protons in all of the atoms in the universe (Sagan, 1979). We have just scratched the surface of this fascinatingly complex subject.
