The human auditory system will analyze the time differences between 2 ears within small range of frequency known as critical bands. If the frequency is less than thousand to thousand five hundred Hertz, the interaural time variation is calculated based on the interaural phase difference in the signals received by both ears. The obtained sound […]

Mu waves, which are also named as wicket rhythm or comb are generally electromagnetic oscillations which are around the frequency range of eight to thirteen hertz and is present in bursts of nine to eleven hertz. The Mu wave patterns generally happen in coherent and synchronous electrical action of huge groups of neurons present in […]

History of idea The idea which differentiates various regions in brain was enthused simultaneously and was recommended through 1988 findings where 2 neurons oscillate simultaneously while a normal external object creates the corresponding receptive fields. The further experiments conducted by various other people indicated that such phenomenon in different categories of visual cognition. Specificially Christof […]

Disorders and Disruptions: The regional delta wave activity will be related with NREM sleep and was described first by W. Grey Walter that studied the tumours in cerebral hemisphere. In certain cases, there is decrease or increase in delta wave activity and in other cases they might cause disruptions in activity of delta waves such […]

Dreaming and Consciousness At first, dreaming was considered to happen in quick eye movement sleep, but it has been discovered now that it might also happen under slow wave sleep. The activity of delta waves is initially expressed through unconscious state and there is lack of physical alertness and also repetition of information. The delta […]

Development The activity of delta waves is considered to be more among infants since they spend more amount of time with slow wave sleep and hence delta waves are considered as principal wave form of infants. The analysis of waking EEG of newborn infant states that delta wave activity could be dominant during that age […]

Variations of delta waves among different sexes: Females show more delta wave activity and are considered to be true among various mammal species. This variation is no to visible till early childhood, during the thirties or forties among humans and men exhibit decrease in activity of delta waves with increase in age when compared to […]

Classification and features of Delta Brain Waves Similar to other brain waves, Delta waves are found out through Electroencephalography (EEG). The delta waves are generally defined based on frequency in range of one to four hertz through various classifications that is placed in boundaries between 0.5 and two hertz. They are slowest brainwaves with highest […]

The delta waves are brain waves of high amplitude and oscillation frequency is in range of 0-4 Hz. Delta waves similar to other brain waves can be recorded using an electroencephalogram. Delta waves are recorded using EEG similar to other brain waves and is generally related with SWS or slow wave sleep and deepest sleeping […]
