The neuron is the one that transfers the message (nerve impulse) to the brain. In the same way, the cell that senses the stimuli in any part of the body is the receptor, not the neuron.

Sometimes different parts of different cells perform other functions, but these tend to be where the neuron receives its signal. And we'll talk more about what it means to receive and transmit a signal in …

My neuroscience textbook classifies any neuron with two neurites as bipolar, and the diagram shows what you describe: the bipolar neuron has two axons going in opposite directions.

Does a certain neuron only send one kind of signal only (different signals would be sent by different neurons) or does a certain neuron send multiple kinds of signals by sending different kinds of …

Action potentials (those electrical impulses that send signals around your body) are nothing more than a temporary shift (from negative to positive) in the neuron’s membrane potential caused by ions …

Key points: A resting (non-signaling) neuron has a voltage across its membrane called the resting membrane potential, or simply the resting potential. The resting potential is determined by …

Most of your synapses are chemical synapses, meaning that information is carried by chemical messengers from one neuron to the next. In the article on synapses, we discussed how synaptic …

In this video, I want to provide an overview of neuron function, which I think of sort of like how a gun functions. And we'll go into a lot more detail on how a neuron functions in later videos.

Most neurons follow the same general structural plan, but the structure of individual neurons varies and is adapted to the specific function a given neuron (or class of neurons) needs to carry out.

So let me start by showing where synapses happen, so first I'll draw the soma of a neuron in red, and a few dendrites, these branching processes of neurons in blue, one dendrite and here's another …
