[Lateral inhibition in neuronal networks and the shape of alpha-rhythm in the EEG]
Abstract:
In 15 volunteers, the background EEG was registered from the right occipital area with eyes closed. Rhythmic photo-stimulation conjugated with a certain phase of the alpha-waves (10 phases) elicited responses that were compared by means of measurement of the alpha-wave average amplitude in each protocol. The wave shape was compared by asymmetry at the level of ascending and descending fronts. The shape changes were most obvious during the stimuli in middle of the descending front, the changes shrply differing from other 9 phases of the stimulation.

Neural Regulation
Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information about food, it triggers impulses in the cranial nerves innervating the salivary glands and stomach to prepare for food.
Brain Waves
Brain waves are electrical signals generated by the neurons in the brain, which are regularly monitored to measure mental activities. Brain waves and their frequency ranges can be measured using an electroencephalogram or EEG. There are four main types of brain waves, each with distinct characteristics:
