We make thousands of decisions every day: where to go, what to do, when to do it. Join UCSD's William Kristan and discover how neurons, synapses, and chemical input play out in decision making. (57 minutes)
Neuroscientist Patricia Churchland explores how the human mind functions in guiding one's decisions. (55 minutes)
In this fascinating presentation, The Salk Institute's Terry Sejnowski explores how by its nature the human brain is susceptible to the effects of addictive substances. (59 minutes)
In this edition of "Grey Matters," Aniruddh Patel, of the Neurosciences Institute, discusses what music can teach us about the brain, and what brain science, in turn, can reveal about music. (51 minutes)
Join Stuart Lipton of The Burnham Institute and discover important anti-aging strategies, the latest drugs for degenerative disorders such as AlzheimerŐs disease and the potential use of human stem cells for neurological conditions. (57 minutes)
UCSD's Charles Zuker explores the neurobiology of taste, smell and vision. (88 minutes)
Is sleep for rest? To conserve energy? For development? To cool the brain? To warm it? To boost the immune system? To learn and memorize? Or to unlearn, ridding our brains of excess mental baggage? All of these ideas have been proposed, leading to the suggestion that insomniacs might do better to count sleep theories instead of sheep. Join renowned neuroscientist Ralph Greenspan of The Neurosciences Institute to explore the latest research into the question of why we sleep. (59 minutes)
During the past decade, there have been dramatic advancements in the brain and cognitive sciences. For the first time, understanding how the brain works has become a scientifically achievable goal. In this new lecture series, Grey Matters: Molecules to Mind, San Diego's leading Neuroscientists explore the human brain. The first lecture in this series addresses an issue that has often been absent in these discussions: what role do stem cells play in development of the brain? (59 minutes)
UCSD cognitive scientist Martin Sereno takes you on a captivating exploration of the brain's structure and function as revealed through investigations with new advanced imaging techniques and understandings of evolution. (57 minutes)
Why are humans the only species to have language? Is there something special about our brains? Are there genes that have evolved for language? In this talk, Jeff Elman, UCSD professor of cognitive science and co-director of the Kavli Institute for Brain and Mind, discusses some of the exciting new research that helps us understand what it is about human language that is so different from other animals' communication systems, and what about our biology might make language possible.

The endoderm will form the lining of the gut and the organs that develop from it. Splanchnic mesoderm surrounds the endoderm and orginates from the lateral plate mesoderm. It will form the smooth muscle of the gut that are used in peristalsis.
The Guttural Pouch is present only in members of the order Perissodactyla (nonruminant ungulates: horses, tapirs, rhinoceros) and another small band of small mammals including Hyraxes, certain bats and a South American mouse.

This resource aims to spread the message that undetectable HIV viral load in the blood is untransmittable via sexual contact.
Hair germs begin from an aggregation of keratinocytes in the stratum basale of the epidermis. The initiating factor is the underlying dermal fibroblast cells. The keratinocytes elongate, divide and relocate to the dermis. Dermal fibroblasts then form a dermal papilla beneath the hair germ. This causes stimulation of the basal stem cells to up-regulate their cycle, producing cells that will keratinise and form the hair shaft. Two swellings form on the shaft, one containing stem cells for follicle regeneration, the other becomes a sebaceous gland which will secrete sebum onto the hair shaft. The follicles develop from an ectodermal bud which invades the mesenchyme during embryonic development. The mesoderm also condenses during the development creating an outer mesodermal component to the embedded part of the hair.

Anatomy of the hand bones. Carpal, metacarpal and phalanges broken down.
Although palpation is a foundational skill for many healthcare disciplines, few resources provide comprehensive anatomical information and relate it to real-world clinical situations. With its detailed descriptions of musculoskeletal anatomy, instructions for palpating anatomical structures, depictions of basic injuries, and correlations with clinical practice, Hands-on Anatomy successfully bridges this gap.
Hands-on Anatomy targets undergraduate or graduate students who have completed an introductory anatomy course and are beginning to apply their anatomical knowledge to the human body, as well as healthcare professionals engaged in patient assessment and treatment. Organized by region of the body, chapters discuss skeletal landmarks, muscles, ligaments, and neurovascular structures, with a focus on how to palpate these structures. Additionally, guides on assessing the range of motion of joints are provided, along with descriptions of common clinical scenarios relating to each body area. The text is supplemented with images of skeletal landmarks and muscular anatomy, photos of surface landmarks and range of motion actives, and end-of-chapter review questions to ensure understanding and retention of what was described.
