World of Biology on Instagram: "Neurons form connections 🧠 They do this by extending an axon toward another neuron’s dendrites or cell body. At the synapse, the first neuron releases neurotransmitters — tiny chemical messengers that cross a small gap and bind to the next neuron. This triggers the second neuron to either fire a signal or stay silent. This simple yet powerful exchange is how your brain communicates. And with learning, practice, and experience, these connections strengthen or chan
