Course Introduction and Vision (Part 1)

This module contains an introduction to the course as a whole (Video 1.1) and an exploration of how our eyes detect light and deduce the location light is coming from (Videos 1.2-1.6). You'll also learn about how scientists from Democritus to Alhazen to Kepler figured this out. The final video for the module involves an experiment to test what happens when special goggles turn the world upside down (Video 1.7). I'll show experiments frequently throughout this course -- they are how we know what we know. This module’s quiz is ungraded and available to both auditors and certificate students. Consider it a sample of the style of question in the quizzes for the remaining modules, and an opportunity to determine if you’d like to pursue a certificate for this course. ...

Vision (Part 2), the Body, and Neural Signals

In this unit, we cover the visual scene in 3D - the many clues to depth. We then turn to body senses (position and touch) and how our brains detect the configuration of our own bodies. Along the way, we cover the resting membrane potential, the action potential, and how they arise. Finally, we bring vision and the body together, and throw some beanbags at a visual target while wearing prisms! This material is covered in Making Space, chapters 2 and 3. ...

Brain Maps

In this unit, we turn to the brain and how it uses the spatial position of neurons within the brain to organize information about the spatial position of stimuli in the world (Making Space chapter 4). You'll learn about how we identify where one object ends and another begins, what a receptive field is, and how some neurons are sensitive to edges and the boundaries of objects. Maps occur in both visual cortex and body (somatosensory) cortex, and these maps may be responsible for various "phantom" sensations (examples from normal vision, patients with body part amputations, and electrical stimulation experiments). ...

Sound and Brain Representations

In module 4, we turn to the fascinating puzzle of how we deduce sound location--a process that requires quite a bit of detective work. Our brains piece together multiple types of clues, including subtle differences in timing, loudness, frequency content, and how sounds appear to change as we turn our heads. Because our ears don't form images of sounds, our brains don't have to use maps to encode sound location. The second half of the videos this module concern alternative forms of brain representation, how the brain translates between different types of representation, and what we know about brain representations for sound location. The material is covered in chapter 5, "Sherlock Ears" and chapter 6, "Moving with Maps and Meters", in Making Space. Be forewarned, there are about 70 minutes of video this module, as compared to previous modules' 50-60 minutes. After watching the full set, you'll see why these videos are grouped together as a unit. To make things more manageable, we've broken the quiz into two parts; that way, you can get feedback on one part before moving on to the next, if you like. ...
