This course provides a comprehensive and concise review of the neurosciences, with special emphasis on recent and important developments in the field. Topics include basic neuroanatomy, neurophysiology, neuropharmacology, neuroendocrinology, neurochemistry, and neurogenetics. The course is intended for clinical psychologists as well as graduate physicians and residents in neurology, neurosurgery, and psychiatry.

Video, slides, and transcripts are freely available.

There are a few other seminars you might want to check out, as well:

Introduction to the Art of Venture Valuation

In this e-seminar, Professor Oren Fuerst of Columbia Business School will provide an overview of the main methods of valuation and then demonstrate some of the adjustments that are typically necessary for early-stage technology companies or projects. The e-seminar includes video, audio with slides, case-study examples of valuation, and an interactive final exercise.

Mathematics of Finance

Professor Mikhail Smirnov's Mathematics of Finance is a two-part course on the basics of probability and finance. This course requires a solid understanding of calculus.

In the following lessons, we will explore the notions of derivatives, futures, and options, as well as theories of volatility, arbitrage, and hedging. We will describe and apply the Black-Scholes formula for pricing options and the theory of Brownian motion as it applies to calculating price and risk.

Small Wonders: The World of Nano-Science

The nanoscale, just above the scale of an atom, is the place where the properties of most common things are determined. It is here that the disciplines of physics, chemistry, biology, and engineering meet and conspire. In this e-seminar, Professor Horst Stormer magnifies the wondrous nano-world and reveals its enormous potential to shape our future.

Basic and Clinical Neurosciences

Research reported this week by three different groups shows that normal skin cells can be reprogrammed to an embryonic state in mice. The race is now on to apply the surprisingly straightforward procedure to human cells.

If researchers succeed, it will make it relatively easy to produce cells that seem indistinguishable from embryonic stem cells, and that are genetically matched to individual patients.

Simple switch turns cells embryonic, removes need for eggs or embryos

The Knowledge Web today is an activity rather than a web site — an expedition in time, space, and technology to map the interior landscape of human thought and experience. Thanks to the work of a team of dedicated volunteers, it will soon be an interactive space on the web where students, teachers, and other knowledge seekers can explore information in a highly interconnected, holistic way that allows for an almost infinite number of paths of exploration among people, places, things, and events.

In what sense might something as intrinsically human as the imagination be biological? How could the products of the imagination – a novel, a painting, a sonata, a theory – be thought of as the result of biological matter? After all, such artefacts are what culture is made of. So why invoke biology? In this essay, I will argue that the content of the imagination is of course determined more by culture than biology. But the capacity to imagine owes more to biology than culture.

Onboard NASA’s Mars Reconnaissance Orbiter, the HiRISE camera offers unprecedented image quality, giving us a view of the Red Planet in a way never before seen. It’s the most powerful camera ever to leave Earth’s orbit.

Offered FYI in response to a recent post.

Freeman admitted he was a skeptic on global warming. His problem was not change in the climate. “In the long view we ARE changing the climate.” He felt that climate was hugely complex, that we understand very little of it and many people are reducing this unknown complexity into one data point — the average temperature somewhere. Until we understand what kind of changes we are making in our “solutions” he says he believes the best action on global climate change right now is inaction.

But I have studied their climate models and know what they can do. The models solve the equations of fluid dynamics and do a very good job of describing the fluid motions of the atmosphere and the oceans. They do a very poor job of describing the clouds, the dust, the chemistry and the biology of fields, farms and forests. They do not begin to describe the real world that we live in.

The real world is muddy and messy and full of things that we do not yet understand. It is much easier for a scientist to sit in an air-conditioned building and run computer models than to put on winter clothes and measure what is really happening outside in the swamps and the clouds. That's why the climate model experts end up believing their own models.

Besides the general prevalence of fudge-factors, the latest and biggest climate models have other defects that make them unreliable. With one exception, they do not predict the existence of El Niño. Since El Niño is a major feature of the observed climate, any model that fails to predict it is clearly deficient. The bad news does not mean that climate models are worthless. They are, as Manabe said thirty years ago, essential tools for understanding climate. They are not yet adequate tools for predicting climate. If we persevere patiently with observing the real world and improving the models, the time will come when we are able both to understand and to predict. Until then, we must continue to warn the politicians and the public: don't believe the numbers just because they come out of a supercomputer.

This paper is from 2005. I have only skimmed it. I'm posting in response to the recent thread Political Preference Is Half Genetic.

We test the possibility that political attitudes and behaviors are the result of both environmental and genetic factors. Employing standard methodological approaches in behavioral genetics —– specifically, comparisons of the differential correlations of the attitudes of monozygotic twins and dizygotic twins —– we analyze data drawn from a large sample of twins in the United States, supplemented with findings from twins in Australia.

The results indicate that genetics plays an important role in shaping political attitudes and ideologies but a more modest role in forming party identification; as such, they call for finer distinctions in theorizing about the sources of political attitudes.

We conclude by urging political scientists to incorporate genetic influences, specifically interactions between genetic heritability and social environment, into models of political attitude formation.

Are Political Orientations Genetically Transmitted?

Welcome to Celestia ... The free space simulation that lets you explore our universe in three dimensions. Celestia runs on Windows, Linux, and Mac OS X.

Unlike most planetarium software, Celestia doesn't confine you to the surface of the Earth. You can travel throughout the solar system, to any of over 100,000 stars, or even beyond the galaxy.

All movement in Celestia is seamless; the exponential zoom feature lets you explore space across a huge range of scales, from galaxy clusters down to spacecraft only a few meters across. A 'point-and-goto' interface makes it simple to navigate through the universe to the object you want to visit.

Celestia is expandable. Celestia comes with a large catalog of stars, galaxies, planets, moons, asteroids, comets, and spacecraft. If that's not enough, you can download dozens of easy to install add-ons with more objects.

Comprehensive, collaborative, ever-growing, and personalized, the Encyclopedia of Life is an ecosystem of websites that makes all key information about life on Earth accessible to anyone, anywhere in the world. Our goal is to create a constantly evolving encyclopedia that lives on the Internet, with contributions from scientists and amateurs alike. To transform the science of biology, and inspire a new generation of scientists, by aggregating all known data about every living species. And ultimately, to increase our collective understanding of life on Earth, and safeguard the richest possible spectrum of biodiversity.

As E.O. Wilson accepts his 2007 TED Prize, he makes a plea on behalf of his constituents, the insects and small creatures, to learn more about our biosphere. We know so little about nature, he says, that we're still discovering tiny organisms indispensable to life; yet we're still steadily destroying nature. Wilson identifies five grave threats to biodiversity (a term he coined), using the acronym HIPPO, and makes his TED wish: that we will work together on the Encyclopedia of Life, a web-based compendium of data from scientists and amateurs on every aspect of the biosphere.
