2-Minute Neuroscience: The Neuron
Neuroscientifically Challenged・2 minutes read
The brain's 85 billion neurons communicate through electrical signals via dendrites, soma, axons, and axon terminals, ensuring proper neural function and information processing. Neurotransmitters stimulate electrical changes, leading to action potentials that travel along myelinated axons to interact with receptors on the dendrites of other neurons.
Insights
- Neurons in the brain communicate through electrical signals transmitted along axons, with neurotransmitters playing a crucial role in this process by facilitating signal transmission between dendrites and axon terminals.
- The intricate structure of neurons, from dendrites receiving signals to axons transmitting action potentials, highlights the complexity and precision involved in neural communication, essential for the brain's functioning and information processing capabilities.
