Revolutionise Neuroscience, Pee in a Cup

ResearchBlogging.org

The title might seem a bit melodramatic, but I’m pretty amazed by some research I found.

In a recent article from Nature Methods a research group have put forward the possibility of generating Neural Stem Cells (NSC’s) from urine.

Ok so for those who don’t understand all of the above, this is pretty big! (hence why it’s in a Nature Journal). Everyone has heard of stem cells and their possibly magical healing abilities, replacing damaged brain/heart/liver (more…)

Believing is Not Seeing: Visual Science and Reality part 2

Let’s get this straight from the off. You don’t see nearly as much as you think you do. In fact you barely see anything. You may think this is an exaggeration but I’m being serious. And I’ll explain why.

Before we start you should read the first post in this series.

Firstly you don’t see smooth motions in the world around you. The neurons in your eyes can’t work that fast (more…)

Believing is Not Seeing: Visual Science and Reality part 1

I’ve had to break this post down into two posts as it got a bit long.

So before I start on this bit I want everyone reading to take part in a very small experiment:

Put a hand over your left eye so you can’t see anything with it. Now lean back from the computer screen and stare at the cross on the left in the image below.

As you stare at the cross, move closer to the image (you can get pretty close).

Complicatedly Colourful: Vision Science

The picture I’ve put up is one of a mouse retina. The green dots are cells that have been stained with a fluorescent dye. I’m showing you this partly to show you how many cells there are in a retina (only some of the cells are stained, and humans have even more than mice). It’s also partly to (more…)

Sight: The Science of Vision

Before I start I’m going to give you a couple of references to some relevant posts I have already made/reblogged:

The basics of sensory science

The causes of sensation – very relevant to this post

A reblogged think on colours and some other issues

If anyone still wants to they can vote in the poll on the sidebar!

OK let’s get started. (more…)

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...

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…)

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...
