WebAlzheimer's is a disease of the brain characterized by plaques (deposits of protein fragment beta amyloid in the spaces between cells) and tangles (build up of tau protein inside cells) an amplified recording of the waves of electrical activity sweeping across the brain's surface. These waves are measured by electrodes placed on the scalp. Webwhite matter. myelinated fibres. main functions of myelin sheath. main functions include. 1. act insulator. 2. protect axon against damage. 3. speed up movement of nerve impulses along axon through nodes of ranvier -allows us to react quicker to stimuli. nodes of Ranvier. gap in the myelin sheath of a nerve fibre.

WebNeurotransmitters are how we communicate between one cell and the next. Synapses between neurons are either excitatory or inhibitory – and that all comes down to the neurotransmitter released. Excitatory neurotransmitters cause the signal to propagate - more action potentials are triggered. Inhibitory signals work to cancel the signal.
