Computer Simulations of Basic Neuronal Function

Abstract:: This laboratory utilizes two user-friendly computer programs from Neurosim (Biosoft, Cambridge, U.K.) that demonstrate various aspects of electrophysiological functions of neurons without sacrificing experimental animals. One program simulates passive conduction in a long length of axon while the second program simulates the Hodgkin-Huxley equations for the production of an action potential. While these programs allow students to try experimental manipulations that parallel those done in real electrophysiological experiments (changing ionic concentrations or voltage stimulus, effects of various drugs, etc.) it also allows them to change some of the inherent properties of neurons, such as membrane resistance and axon resistance. This enables one to see how neurons of different physical characteristics differ in their electrical behavior. This laboratory is suitable for students of varying backgrounds.

Journal of Underdergraduate Neuroscience Education

Abstract:: The Journal of Underdergraduate Neuroscience Education (JUNE) is a publication of the Faculty of Undergraduate Neuroscience. JUNE is an online journal for undergraduate neuroscience faculty that publishes peer-reviewed reports of innovations in undergraduate neuroscience education. JUNE serves as a mechanism for faculty to exchange information regarding topics such as laboratory exercises, new media, curricular considerations, and teaching methods.

Abstract:: This book inevitably asks the question "How does the mathematical brain work?" The author tries to reflect on the explosive development of mathematical cognition, an emerging branch of neurophysiology which purports to locate structures and processes in the human brain responsible for mathematical thinking.

Abstract:: Understanding the brain's remarkable ability for visual object recognition is one of the greatest challenges of brain research. The goal of this course is to provide an overview of key issues of object representation and to survey data from primate physiology and human fMRI that bear on those issues. Topics include the computational problems of object representation, the nature of object representations in the brain, the tolerance and selectivity of those representations, and the effects of attention and learning.

Abstract:: What are the circuits, mechanisms and representations that permit the recognition of a visual scene from just one glance? In this one-day seminar on Scene Understanding, speakers from a variety of disciplines -- neurophysiology, cognitive neuroscience, visual cognition, computational neuroscience and computer vision -- will address a range of topics related to scene recognition, including natural image categorization, contextual effects on object recognition, and the role of attention in scene understanding and visual art. The goal is to encourage exchanges between researchers of all fields of brain sciences in the burgeoning field of scene understanding.
