Introduction to neurons and glia. How the structure of a neuron allows it to receive and transmit information.

Neurons (or nerve cells) are specialized cells that transmit and receive electrical signals in the body. Neurons are composed of three main parts: dendrites, a cell body, and an axon. Signals are received …

A neuron will always send the same size action potential. So how do we show that some information is more important or requires our attention right now? The answer lies in how often action potentials are …

This video introduces the structure and structural types of neurons. Explore the structure of neurons, their types, and functions. Uncover the roles of dendrites, axons, and the soma. Learn about the …

This video explains neuron graded potentials, detailing how they are created and why they decay over time and distance. It highlights the role of neurotransmitter receptors and ion channels in generating …

Explore how neurons process information through graded potentials. These transient changes in membrane potential occur in response to stimuli, influencing the neuron's behavior. Discover the role …

At the synapse, the firing of an action potential in one neuron—the presynaptic, or sending, neuron—causes the transmission of a signal to another neuron—the postsynaptic, or receiving, …

Learn about depolarization, hyperpolarization, and action potentials in neurons with Khan Academy's comprehensive biology resources.

Inhibitory signals work to cancel the signal. Every time an action potential is triggered in a neuron, that cell will release whatever types of neurotransmitter it has, because calcium cannot tell the difference …
