Professor Robert Sapolsky finishes his lecture on language and then dives into his discussion about schizophrenia. He discusses environmental factors as well as genetic characteristics that could apply to people who are affected. He describes schizophrenia as a disease of thought disorder and inappropriate emotional attributes.
Professor Robert Sapolsky gives what he calls "one of the most difficult lectures of the course" about chaos and reductionism. He references a book that he assigned to his students. This lecture focuses on reduction science and breaking things down to their component parts in order to understand them best.
Robert Sapolsky continues his neurobiological exploration of human aggression. He discusses correlations between neurotransmitter prevalence and aggression levels, aggressive activity differences from genetic variance, societal factors and application, amplification from alcohol, and crime and punishment.
Robert Sapolsky explores behavioral patterns of human reproduction. He focuses on proximal and distal motivations, orgasm and fertility facilitation, non-reproductive sex, hormonal and cerebral sexual functions, and the differences and similarities between humans and animals in various physiological realms.
Robert Sapolsky continues the exploration of endocrinology and neurology. He looks at more complicated systems of communication within neurobiology, the limbic system's role in personality and behavior, abnormal behavior possibilities within these systems, and individual organism variation and imprinting.
Robert Sapolsky looks at the biology of behavior through the ethological lens: observing animals in various natural environments, in their own language. He explores behavioral variety, the importance of gene environment interactions, experimental testing of fixed action patterns, the releasing of informational stimuli, and neuroethology.
Robert Sapolsky discusses various methods of innate recognition of relatives between animals and humans through protein signatures, olfactory cellular mechanisms, cognitive, and sensory processes. He explores the importance of relatedness in animal mating/ovulation cycles and other phenomena that show how organisms identify each other.
Robert Sapolsky continues his series addressing the link between behavior and genetics. He covers the complex endeavor of gene isolation and variability and heritability and wrongly eliminated environmental influences in heritability tests -- finding that genes and environment are infinitely interconnected and co-dependent on each other.
Robert Sapolsky introduces a two-part series exploring the controversial scientific practice of inferring behavior to genetics. He covers classical techniques in behavior genetics and flaws, the significance of environmental factors, non genetic inheritance of traits, and multigenerational effects and relationship to epigenetic differences.
Robert Sapolsky continues his series on molecular genetics in which he discusses domains of mutation and various components of natural selection on a molecular level. He also further assesses gradualism and punctuated equilibrium models of evolution, integrating these theories into an interrelated model of development.
Robert Sapolsky makes interdisciplinary connections between behavioral biology and molecular genetic influences. He relates protein synthesis and point mutations to microevolutionary change, and discusses conflicting theories of gradualism and punctuated equilibrium and the influence of epigenetics on development theories.
Robert Sapolsky continues his two-part series on evolution focusing on individual and kin selection, behavioral logic, competitive infanticide, male/female animal hierarchies, sex-ratio fluctuation, intersexual competition, imprinted genes, sperm competition, inbred-founder populations, group and multi-level selection, and punctuated equilibrium.
