Everything our brain does, from controlling movement to conscious thought, is achieved by the firing of electrical signals called neurons.
- Everything our brain does is achieved by electrical signals produced and conducted by cells called neurons.
- Neurons are linked by tiny gaps called synapses.
- Electrical signals cannot pass directly across a synapse, so are converted into chemicals such as serotonin and dopamine.
- As synapses become established, the transmissions between the two cells become easier and quicker.
Everything our brain does – from controlling movement, to conscious thoughts, to producing emotions, is achieved by the firing of electrical signals.
The cells that produce and conduct these electrical signals are called neurons.
