Neuronsdon’t touch each other — but still communicate!
They exchange signals across tiny gaps called synapses, firing up to 1,000 times per second.
You’re born with nearly all the neurons you’ll ever have
But what changes? Their connections — millions formed every minute in childhood.
Each neuron is a universe of its own
A single neuron can connect to 10,000 other neurons, forming trillions of pathways.
Neurons talk in electricity + chemicals
Electrical impulses travel along axons, while neurotransmitters carry the message across synapses.
Some neurons are longer than 1 meter
Especially motor neurons running from your spine to your toes!
Your memories are made by neurons wiring together
Long-term memory literally forms when synapses strengthen and reorganize.
You make new neurons — even as an adult
In the hippocampus, neurogenesis continues, helping learning & emotional balance.
A Message of Awe
Neurons shape every sensation, movement, thought, fear, memory, decision, and dream.
They are the invisible storytellers of your life — firing silently yet shaping everything loudly.
Very fascinating to know that the whole nervous system runs without neurons touched each other. Thanks to neurotransmitters which spread every message from one neuron to the other.
It’s so intriguing when you realise that all our thoughts, emotions and cognition are because of these various chemicals transmitted between the cells in the nervous system!
Neurons are absolutely mind-bending, tiny biological sparks that quietly run the entire universe inside us. The fact that they never actually touch yet communicate at lightning speed feels almost supernatural. And those long motor neurons stretching over a meter? It’s like having microscopic cables engineered with perfect precision. The idea that memories form through strengthened synapses makes every life moment feel physically etched into us. Even more incredible, our brains keep growing new neurons in the hippocampus, giving us hope for lifelong learning and emotional renewal. Truly, neurons are the silent architects of our identity, tirelessly shaping every thought and feeling.
I think the fact that our long term memories are made by strengthening synapses and reorganizing is fascinating for me. Neurons and neurology is vast subject that has so much to explore.
