Neural Networks
Northeastern University social psychologist Lisa Feldman Barrett relates how modern neuroscience has moved from focusing on the behaviour of individual neurons to examining neural networks - vast numbers of neurons linked together.

How The Giant Squid Axon Changed Neuroscience
A lot of techniques and methods used in neuroscience have been developed thanks to modern technology and science. But what did neuroscientists do back in the day before all this fancy stuff? Well, turns out the giant squid axon was...

How the Heart Contracts - Step by Step
Let's dive into the cardiac action potential and how it results in the contraction of the heart. We'll talk about the signal that starts at the SA node and spreads throughout the heart. We'll also get into the phases of depolarization,...

Neural Conduction, Action Potential, and Synaptic Transmission
We have probably heard that neurons are the cells that transmit information around the body. But how does this work? Is it actual electricity? Like from the wall socket? What is a synapse? What happens there, in between one neuron and...
