Nervenet
We are building a practical human brain-computer intrface intended for a wide range of application.
Neurons
There Are 86 Billion
Neurons in Your Brain
Neurons send and receive information. Although neurons come in many different types, they generally have three parts: a dendrite which receives a signal, a cell body called a soma which computes the signal, and an axon which sends a signal out.
Synapses
Neurons Are Connected
Through Synapses
The neurons of your brain connect to each other to send and receive signals through axon-dendrite connections called synapses.
Electric Signals
Neurons Communicate
Through Electric Signals
Action potentials cause synapses to release neurotransmitters. These small molecules bind to receptors on dendrites, opening channels that cause current to flow across the neuron’s membrane. When a neuron receives the ‘right’ combination of spatiotemporal synaptic input, it initiates an action potential.
Electrodes
We Can Record Electrical
Signals in the Brain
We place electrodes near neurons in order to detect action potentials. Recording from many neurons allows us to decode the information represented by those cells. In the movement-related areas of the brain, for example, neurons represent intended movements. There are neurons in the brain that carry information about everything we see, feel, touch, or think.
