Your brain’s storage capacity is considered immense. Research suggests the human brain consists of about 86 billion neurons. Each neuron forms connections to other neurons, which could add up to 1 quadrillion (1,000 trillion) connections. Over time, these neurons can combine and further increase storage capacity. They can also become damaged and stop working, such as in diseases like Alzheimer’s disease, affecting memory in particular.

Brain information can travel up to an impressive 350 miles per hour. When a neuron is stimulated, it generates an electrical impulse that travels from cell to cell.
