Epilepsy: Signals 'brake' in brain impaired

...ls are interlinked via a large number of branching networks through which they communicate with each other. Each neuron has a series of dendrites which receive signals from other neurons at what are known as synapses. The cell 'processes' these incoming signals like a kind of biological microprocessor and tra...
