PSB 4006: Biological Bases of Behavior 2

Uncover the role of teratogens in fetal development with a focus on alcohol's impact. Understand the critical function of the placenta and how certain substances can bypass this protective barrier, potentially harming the fetus. Grasp the risks and implications of alcohol consumption during pregnancy.

Discover the powerful role of conformity in shaping human behavior. Through relatable scenarios, learn how our choices can be influenced by peer pressure and societal expectations. Understand the balance between adapting to social norms and preserving individuality.

Discover how Signal Detection Theory helps in identifying signals in a cluttered setting. This video unpacks its four key outcomes—Hit, Miss, False Alarm, and Correct Rejection—and explores its relevance in various perception processes like vision, smell, and absolute thresholds.

Discover the significance of studying fraternal twins in genetic research. Understand the unique blend of shared environments and differing genetic codes. Grasp how their study enlightens the genetics vs environment debate.

Discover the factors influencing the risk of major depression and bipolar disorder. Unpack the roles of genetic predisposition, family history, and life events in mental health. Learn why a biological family connection stands out as the most significant risk factor.

Discover the essential process of neural pruning in brain development, distinct from creating new connections, managing neural waste, or increasing brain weight. Uncover how this natural "clean-up" refines our neural network, making our brains more efficient in processing information. Explore the impact of neural pruning on cognitive growth and the interaction between genetics and environment in brain development.
