Neuron has a receiving end and a transmitting end and it"s role was to transmit signals. Receptors specialized cells that pick up information from the environment. Neurons are not connected indiscriminately by form connections only to specific neurons. Neural circuits when many neurons are connected together. Edgar adrian: able to record electrical signals from single sensory neurons. Action potential: travels all the way down the axon without changing its size. Neurotransmitter chemical released that makes it possible for the signal to be transmitted across the synaptic gap. The idea tha specific functions are serced by specific areas of the brain.
