What do your dreams mean? Do men and women differ in the nature and intensity of their sexual desires? Can apes learn sign language? Why can't we tickle ourselves? This course tries to answer these questions and many others, providing a comprehensive overview of the scientific study of thought and behavior. It explores topics such as perception, communication, learning, memory, decision-making, religion, persuasion, love, lust, hunger,

Professor Diamond continues her discussion of the nervous system and begins by revisiting her discussion of the ascending path. She notes the presence of substantia gelatinosa in the area of the second neuron and describes the concept of homunculus, which is the upside-down representation of the body in the brain, and notes that this does not occur in the face for reasons unknown to neurologists. Professor Diamond then begins describing...more

Professor Diamond continues her discussion of the nervous system with an introduction of the cerebral hemisphere and it is divided into lobes with specific functions. She uses Brodmann's numbering system as she draws the location of lobes and areas of the brain, including the precentral, postcentral, and premotor gyri, the central sulcus, motor cortex, frontal eye fields, and prefrontal lobe. She details the functions of the prefrontal...more

In this lecture on the male reproductive system, Professor Diamond begins by covering the primary sex organ (the gonad or testis). She discusses its function in producing sperm and testosterone, location within the male body, and the reason it is enclosed in a separate pouch called the scrotum (temperature regulation by the eremasteric muscle). Then she talks about the source of sperm, structure of the testis, in particular, the lobules,...more

In this lecture, Professor Diamond conducts a review of previous lectures including areas of the respiratory system, nervous system, vascular system, as well as hematology and cardiology. Her review takes the format of a quiz as she goes through slides and asks students to identify parts of the slides as well as answer multiple choice and true or false questions. Questions involve topics such as the hyelin cartilage, the trachea, lungs,...more

This penultimate lecture concludes the discussion of the male reproductive system. Here Professor Diamond introduces the sex glands, which include the seminal vesicles, prostate and the balbo urethra glades, detailing their location, functions and secretions. These secretions include acid phosphate from the prostate, which is used to detect prostate cancer. She then turns to the penis, diagramming its components, location of glands,...more

Professor Diamond continues her discussion of the nervous system, finishing her discussion of the derivatives of the neural tube. She begins by discussing the lamina terminalis and the four ventricles, relating each to the source of their derivation and the areas of the brain in which they are found. Next, she continues her discussion of diencephalon from the last lecture and describes the roles of the thalamus and hypothalamus. After...more

In this lecture, Professor Diamond continues with the cerebral lobes and covers a variety of illnesses that occur in the cerebral lobes including neglect syndrome, Wernicke's Syndrome, and hallucinations. She also spends time on the temporal lobe, the occipital lobe, and the insula, its components and how it affects the body. Then she moves on to the composition, function and location of the eye and its constituents. She briefly covers...more

Professor Diamond continues her discussion of the nervous system beginning with a discussion of myelin-forming oligodendrocytes and Schwann cells, saltatory conduction from the nodes of ranvier, and the similarity of the function of microglia to monocytes. She moves on to describe the development of the neural tube by drawing a cross-section of the neural tube and depicting the changes it undergoes, forming the ventricles of the brain,...more
-
Professor Diamond continues the second lecture on the vascular system beginning with a closer look at the middle cerebral artery, its composition and function, as well as its relationship with other areas of the brain. The second set of the more distinctive arteries are the vertebral arteries, which supply about 25% of the brain's blood supply. After covering how the vascular system relates to the spinal cord, Professor Diamond moves onto...more

In this lecture, Katie Brakora, the head GSI, introduces the course and the required texts and discusses strategies for success in studying human anatomy. She encourages students to take a systemic view of human anatomy, understanding systems in whole and in part, rather than focusing on memorizing terms. After this introduction, Brakora discusses the attributes of the human brain using a preserved sample. Then, Brakora surveys the...more
