During seizures, there is an increase in the firing of action potentials by neurons followed by a period of reduced excitability. This cyclical process is modulated by inhibitory (GABA) and excitatory (glutamate) neurotransmitters. When the reduction in excitability is incomplete, seizures may be triggered by the uncontrolled recruitment of neighbouring neurons.Aδ fibres are relatively fast myelinated fibres C fibres are very fine, slow, non-myelinated fibresThis technique is based on the difference in magnetic properties of oxyhaemoglobin and deoxygenated haemoglobin in bloodA high degree of precision in both the spatial arrangement of neurons and their connectivity is achieved from the outset, the wiring of some parts of the nervous system is later subject to activity-dependent refinement, such as the pruning of axons and the death of neurons
