This course is about how the brain creates our sense of spatial location from a variety of sensory and motor sources, and how this spatial sense in turn shapes our cognitive abilities. Knowing where things are is effortless. But “under the hood,” your brain must figure out even the simplest of details about the world around you and your position in it.
Recognizing your mother, finding your phone, going to the grocery store, playing the banjo – these require careful sleuthing and coordination across different sensory and motor domains. This course traces the brain’s detective work to create this sense of space and argues that the brain’s spatial focus permeates our cognitive abilities, affecting the way we think and remember.
The course material overlaps with classes on perception or systems neuroscience, and can be taken either before or after such classes.
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.
Graded: Module 2 Quiz
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.

Reference Frames and Navigation
This module we turn to how spatial locations are defined, and discuss the concept of a reference frame. Initially, reference frames are quite different for visual, auditory, and somatosensory information. Visual location is defined with respect to the eyes, whereas sound locations are detected with respect to the head and ears, and tactile locations are detected based on body surface position. As you'll see, the brain transforms these signals into new reference frames to facilitate interactions between these sensory systems. We then consider space on a larger scale, and ask how we know where we are and how we navigate from one place to another. Knowledge of self-motion relies in part on the vestibular system, our sense of balance. The vestibular system works in concert with vision and motor systems to update our sense of position and keep us from getting lost. This module's material is covered in chapters 7, "Your Sunglasses Are in the Milky Way", and 8, "Going Places" of Making Space.

Memory and Cognition
In this final module of the course, we build several important links between the sense of space and other kinds of cognition. Videos 6.1-6.5 concern the relationship between space and memory. Memory is reflected in multiple different kinds of neural mechanisms and involves multiple brain regions. The memory and spatial functions of these mechanisms and brain regions overlap. Video 6.5 in particular features work by John O'Keefe concerning response patterns known as "place fields" in the hippocampus, and work by May-Britt and Edvard Moser concerning grid cells. This seminal work was recognized by the 2014 Nobel Prize in Medicine and Physiology. Videos 6.6-6.9 turn to thought more generally, and present a series of theories and experiments that suggest that the brain is actually using sensory and motor structures to think and reason. Thus, our brain systems for space may be engaged in a wide set of mental functions, which are shaped by the multiple purposes of this neural infrastructure. This module's material is covered in chapters 9, "Space and Memory", and 10, "Thinking about Thinking" of Making Space. I hope you enjoy this synthesis of all you have learned and what it means!
These are very unique times for brain research. The aperitif for the course will thus highlight the present “brain-excitements” worldwide. You will then become intimately acquainted with the operational principles of neuronal “life-ware” (synapses, neurons and the networks that they form) and consequently, on how neurons behave as computational microchips and how they plastically and constantly change - a process that underlies learning and memory.
The World Federation for Mental Health prescribes: “Stimulate new areas of your brain and grow more connections among brain cells by intellectually challenging yourself. Solve a puzzle, learn a new musical instrument, read a challenging book, play a board or card game, attend a lecture or play, or write a short story”. This Neuropsychotherapy Course helps therapists and teachers adapt digital gamification and multimedia to provide such stimulation. It builds from basic audio-visual skills to comprehensive studio techniques, all within conventional budget limits.
This course explores the brain bases of bilingualism by discussing literature relevant to differences in age of initial learning, proficiency, and control in the nonverbal, single language and dual-language literature. Participants will learn about the latest research related to how humans learn one or two languages and other cognitive skills.
This course gives you easy access to the invaluable learning techniques used by experts in art, music, literature, math, science, sports, and many other disciplines. We’ll learn about the how the brain uses two very different learning modes and how it encapsulates (“chunks”) information. We’ll also cover illusions of learning, memory techniques, dealing with procrastination, and best practices shown by research to be most effective in helping you master tough subjects.
This course will introduce you to some of the main areas of research in contemporary philosophy. Each module a different philosopher will talk you through some of the most important questions and issues in their area of expertise. We’ll begin by trying to understand what philosophy is – what are its characteristic aims and methods, and how does it differ from other subjects? Then we’ll spend the rest of the course gaining an introductory overview of several different areas of philosophy.
What do your dreams mean? Do men & women differ in the nature & intensity of their sexual desires? Why cant we tickle ourselves? Can Chimpanzees learn sign language? This course will try too answer these questions & many others, providing a comprehensive overview of the scientific study of thought & behavior.
Learn how the nervous system produces behavior, how we use our brain every day, and how neuroscience can explain the common problems afflicting people today. We will study functional human neuroanatomy and neuronal communication, and then use this information to understand how we perceive the outside world, move our bodies voluntarily, stay alive, and play well with others.
