Neurons Latest News
A new study (2025) has identified dendritic nanotubes (DNTs) in the brains of mice and humans, a new form of neuron-to-neuron connection.
About Neurons
- Neurons (nerve cells) are the fundamental units of the brain and nervous system.
- They are responsible for:
- Receiving sensory input from the environment.
- Sending motor commands to muscles.
- Processing and transmitting electrical and chemical signals.
- Structure of Neuron:
- Dendrites → receive incoming signals.
- Cell Body (Soma) → integrates signals.
- Axon → carries impulses away from the cell body.
- Axon Terminals → release neurotransmitters at synapses.
Neuronal Communication
- Traditionally, neurons communicate via synapses where neurotransmitters cross gaps.
- New Discovery: Neurons may also connect via nanotubes (DNTs), enabling: direct electrical signal transfer.
- Protein transport (including amyloid-beta, linked to Alzheimer's).

Neurons FAQs
Q1: What are neurons?
Ans: Neurons are specialized cells of the nervous system responsible for receiving, processing, and transmitting information.
Q2: What is the new discovery about neuronal communication?
Ans: Researchers found dendritic nanotubes (DNTs) that allow neurons to exchange signals and proteins directly.
