Part 4: Dopamine: The Molecule of Addiction | Your Brain on Porn | Animated Series

Here’s the normal pattern of dopamine release. It looks something like a roller coaster because in biology, ‘what goes up must come down’. It could be food, sex, even water when you’re thirsty. So let’s say, you’re starting to get hungry. Well that causes dopamine to start rising and then you think about a burger […]

Darpa N3 Project: Will We Pilot Drones Through The Brain?

There are a lot of advances in technology that are a bit hard to think about when you’re told them. So join us as we explore DARPA and the N3 Project. 9. What is the N3 Project? With a name like the “N3″ project, you’re likely thinking of some big kind of weapon, or some […]

Recording electrodes to monitor brain activity

[Music] My name is Matt Jones. I’m a neuroscientist based in the School of Physiology, Pharmacology and Neuroscience here in Bristol. Well, as you appreciate, our brains are pretty complicated machines. They’re processing lots of different types of information at any given time. And to achieve that, they have lots of specialised brain regions which […]

Scientists Can Implant Fake Memories in the Brain, Here’s How

Human memory is unreliable enough as it is, but researchers interested in better understanding how and where our memories are stored are developing new ways to manipulate them. The search for memory “engrams,” a collection of identifiable neurons that physically represent a memory, has occupied scientists for over a hundred years. Turns out, memory is […]

2-Minute Neuroscience: Electroencephalography (EEG)

Electroencephalography, or EEG, is a technique used to measure the electrical activity of the brain. In EEG, electrodes are most commonly placed on the scalp of a patient, primarily to detect the electrical activity of neurons in the cerebral cortex. Typically, EEG does not record the activity of single neurons, but rather detects the signals […]

Utah electrode array

So, the Utah electrode array is built out of silicon and it’s a very delicate, small device. It’s a quarter of an inch on a side. It’s composed of a hundred little micro-needles that are about an eighth of an inch long that project out from this silicon substrate. Each one these little needles is […]

How We Manipulate Our Brains With Electricity

This episode is sponsored by Audible. To get started, go to audible.com/scishowpsych or text “SciShowPsych” to 500 500. {♫Intro♫} It’s a classic sci-fi plot device: A chip is implanted into someone’s brain, and with a jolt of electricity, their brain is suddenly under someone else’s control. As with all good sci-fi, this is mostly fiction. […]
