The Action Potential and the Nerve Impulse,otentials, which are brief (usually of the order of milliseconds) changes in the membrane potential of a cell produced by the flow of ionic current across the membrane, are not limited to neurons but may also occur in other types of cells, such as striated, cardiac and some smooth muscle, gland cell

The Presynaptic Neuron I: Release of Neurotransmitter,unction and the giant synapse in the stellate ganglion of the squid. The former was especially useful for studying the actions of transmitter on the postsynaptic cell and general properties of transmitter release, and the latter for studying the link between the nerve impulse and the release of tran

The Presynaptic Neuron II: Neurotransmitters,he transmitter at both of these synapses is acetylcholine (ACh). In the present chapter transmitters in general are considered, in particular the criteria needed to identify a transmitter, the way in which different transmitters can be classified, the metabolic pathways for synthesis of some transmi

The Postsynaptic Neuron I: Actions of Neurotransmitters,mbrane of the postsynaptic cell. (Some transmitters, upon release, combine with receptors — autoreceptors — on the presynaptic neuron, see Chapter 7.) The combination of transmitter with receptor leads to changes in the postsynaptic cell that can be of two general types, either affecting chemically

The Postsynaptic Neuron II: The Neuron as an Integrative Device,is the structural (cellular) and functional unit of the nervous system. From his doctrine he inferred the law of dynamic polarisation, namely that all neurons are dynamically polarised such that excitation can only be transmitted from the axon of one neuron to the dendrites or soma of another, and,

Functional Organisation in Groups of Neurons,ven to the stretch reflex in Chapter 10 (with some detail of transmission in the pathway in Chapter 9 and of the workings of the muscle spindle in Chapter 11) and also to some aspects of neuronal group organisation in Chapter 10. This chapter discusses how the interconnection of excitatory and inhib
