The Snake Detection Hypothesis proposes that the ability to quickly spot and avoid snakes is deeply embedded in primates, including us - an evolutionary consequence of the danger snakes have posed to us over millions of years.

Why do spiders have 8 eyes? It’s a seemingly simple question with a surprisingly complex answer. We’ll be hanging out with some jumping spiders (the cutest of all spiders) and some jumping spider researchers to investigate how a...

What color is a banana? Duh, it’s yellow. But what is yellow? Now that you mention it, how do we see color in the first place? That’s the series of questions that led me to making this video. It started simple and took me down a rabbit...

Optical illusions are fun, but they can also teach us a lot about how our brains work. In particular, how our brains accomplish the incredible feat of constructing a three-dimensional reality using nothing but 2-D images from our eyes. A...

If you're old enough to drink, you may have had a few too many cocktails and suddenly everything is spinning. Strange as it might seem, that’s not because the alcohol you drank is messing with your brain! So what causes the spins?

There have been remarkable advances in understanding the brain, but how do you actually study the neurons inside it? Using gorgeous imagery, neuroscientist and TED Fellow Carl Schoonover shows the tools that let us see inside our brains.

What does real scientific work look like? As neuroscientist Stuart Firestein jokes: It looks a lot less like the scientific method and a lot more like "farting around ... in the dark." In this witty talk, Firestein gets to the heart of...

Jeremiah is a computer-based character with a face that can interact with people through simple expressions. Created for an art exhibition, Jeremiah's visual system tracks moving objects and changes its expression accordingly. This...

Step into the exciting world of roller coasters and learn how they blend physics with fun to deliver thrilling experiences safely. This video takes you behind the scenes to uncover how roller coasters are designed to maximize...

Neuroscientist Jennifer Groh (Duke) describes an often-overlooked problem associated with how the brain processing different streams of sensory information.

President Trumpês proposed budget will cut $7 billion in NIH funding - over 20% of the total NIH budget. You might be wondering, where does that NIH money get spent? This week, we interviewed some UCSD Neuroscientists to tell you about...

Sabine Kastner, a professor of neuroscience and psychology at Princeton University, is studying how the brain determines what information is most important in everyday scenes. Using functional magnetic resonance imaging, Kastner is able...

NASA SUITS activity manager Brandon Hargis and technical lead Paromita Mitra talk about the opportunity for students and teachers to design and create spacesuit information displays in augmented reality environments. HWHAP Episode 173.

Let's explore the history and visual illusion of the barbershop pole. Originally a symbol of bloodletting, the pole's rotating stripes create a paradox in our perception of motion. Through research conducted by psychologists in the 20th...

In this video, we explore the concept of lateral inhibition, which is the process by which neighboring neurons in our brain pathway inhibit each other. This phenomenon enhances our visual system's ability to respond to edges of a...

Letês use our words to talk about words - how does our brain process language? Join us this week as Alie dives into some of what we know about the neuroscience of language, and some of what we donêt know, too! NOTE: Pardon the green...

I can see clearly now the rain is gone...oh, and because I know all about the VISUAL SYSTEM! Going beyond the physics of the eye and how light works, how much do you know about how visual information gets sent to the brain? Alie...
