Neurons
Neurons are specialized cells that transmit electrical and chemical signals throughout the nervous system, forming the fundamental building blocks of thought, sensation, and movement.
Numbering in the tens of billions within a single human brain and connected through trillions of specialized junctions, these remarkable cells form the physical basis for every thought, memory, and sensation we experience.
The Building Blocks of the Nervous System
Neurons are specialized cells that transmit electrical and chemical signals, forming the fundamental building blocks of the entire nervous system.
An Estimated 86 Billion in the Human Brain
The human brain contains an estimated 86 billion neurons, each capable of forming thousands of connections with other neurons.
Communicating Through Synapses
Neurons communicate with each other through specialized junctions called synapses, using both electrical impulses and chemical neurotransmitters.
The Physical Basis of Thought
The complex network of neuronal connections forms the physical basis for thought, memory, sensation, and movement, representing one of biology's most complex systems.
