Neurons as Cells

Everything our brain does, from controlling movement to conscious thought, is achieved by the firing of electrical signals called neurons. Biology - Being Human - Learning Points. 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. A Twig Curriculum Film. Delivering key learning points.
