That ‘wow’ moment; when a neuron signals 😍
The brain contains approximately 100 billion neurons that are located in different brain regions.
Within each region, neurons are connected to each other to form neural circuits of amazing complexity.
To function in such circuits, each neuron must receive and process information entering from one set of neurons and then relay signals to other neurons in the circuit.
A typical neuron is divided into three parts: the cell body, the dendrites and the axon.
The cell body; the center of the neuron, extends its processes called the axon and the dendrites to other cells.
Dendrites typically branch profusely, getting thinner with each branching.
The axon is thin but can reach enormous distances.
The electrical impulse mostly arrives on the dendrites, gets processed into the cell body to then moves along the axon.
The key to neural function is the synaptic signaling process, which is partly electrical and partly chemical.
Once the electrical signal reaches the synapse, a special molecule called neurotransmitter is released by the neuron.
The neurotransmitter will then stimulate the second neuron, triggering a new wave of electrical impulse, repeating the mechanism.
