Chapter 2. Biological Basis of Behaviour
Within all of us lies a three-pound organ responsible for coordinating the symphony of our human experience. From the automatic blink to the strategic planning behind your last chess move, the brain shapes every aspect of our behaviour -our thoughts, feelings and emotions. Understanding human behavior has always been at the heart of psychology, driving an endless quest to decode the mysteries of how we act, think, and feel. This chapter will cover essential topics that underpin our understanding of human behaviour.We will begin by covering the various regions and functions of the brain, understanding how different brain regions contribute to various functions. Next, we will explore the nervous system, the body’s intricate communication network comprising neurons, neurotransmitters, and supportive cells. Through this, we will uncover how the nervous system transmits vital information, regulates bodily functions, and interacts with external stimuli to drive behavior.We will also delve into the nature-nurture question, exploring the dynamic interplay between our biology and environment in shaping us. Additionally, we will explore the profound influence of the endocrine system on behavior through the regulation of hormones. This chemical system, composed of glands that secrete hormones into the bloodstream, plays a pivotal role in modulating various physiological processes and behaviours.
