The Skin is Also a Map

I was originally going to start posting on the actual senses with vision, but this is a far better way to go about it!

I’ve had a couple comments on patterns of activity defining the senses. I’m going to use our sense of touch to point out that it isn’t really the patterns of activity that define a sense, but where that activity comes from, and where it goes to.

He's not a freak! He's a Homunculus...



A nice post on the limits of our senses. With a few great illustrations!

First half has a nice explanation of the science. The second half concentrates on other issues, but is still an interesting read!

Cedar's Digest

I don’t often write about gender and science, but I have been thinking and reading about it lately. If you were hoping for my typical aloof lecturing, or overblown (yet intellectual) ranting, just wait a few days (or you could revisit what I think of David Brooks and Larry Summers).

At a wonderful dinner out at the recent Science Online Conference, I found myself explaining why I consider myself a psychologist, even though some people don’t consider the study of visual perception “psychological.” This comes up often in response to the question: “Are you going to use your psychology knowledge to analyze me?” “I’m not that kind of psychologist,” I say. Then, because the food hadn’t come yet, and I had drunk a beer on an empty stomach, I waxed poetic about the color purple. I launched into an explanation of how we perceive color, and how an…

What’s Your Favourite Sense?

I’ve added a new poll in the sidebar so people can vote for their favourite sense.

I thought it might be interesting to see which ones people can’t live without. (bear in mind all those who live without some of these senses already)

The Key to the Senses: Transduction

Here’s probably the most basic question in all of sensory neuroscience (the study of the senses). How does a ray of light enter our nervous system, to eventually become something that we see? How in fact does anything external (anything we touch, smell, taste, hear or see) get turned into something internal (some kind of signal in the brain that tells us to sense something).

The answer is simple, so simple in fact that it is one word: (more…)

Just a quick reblog for anyone who still has doubts about evolution. A small recommendation.

Myth Debunker: We Only Use 10% Of Our Brains.

Myths are a plague upon Science!

Great for Hollywood, especially disaster movies, but a plague for Science!

One of the my pet hates is the myth : “We only use 10% of our brains!”

some of us probably use even less...


The Brain and Reality

Prepare yourself for a weird post.

Forget everything you know about the world and how it looks. Everything you have ever seen, everything you have ever heard, even everything you have ever felt and smelt, is not real. It’s all just pretend. I’m not joking either, everything you have ever experienced has been made up. (more…)

The Brain in Technicolour

I thought this picture that I used in my last post deserved a proper explanation.

Firstly I want to point out that yes, it is a brain. Most of us probably think they all look like (more…)

The Brain is also a Computer – Man or Machine

How do we see?

How do we feel?

How do we think?

There are so many huge philosophical questions that can be answered with: ‘Our Brain does it.’

Man or Machine?

We know which part of us gives us the beauty of life, what most people don’t know is how it does it. (more…)
