Question

Delta () waves are prominent in stage 3 and 4 of sleep. It is the dominant rhythm in infants of up to one year in age. Brain damage is indicated if this pattern appears in awake adults. Most individuals diagnosed with Attention Deficit Disorder increase rather than decrease delta activity when trying to focus. This inappropriate "delta response" often severely restricts their ability to focus and maintain attention Theta (0) waves are irregular in patten, with a low frequency and amplitude. They begin to replace alpha waves in stage 1 of sleep, and are thought to be indicative of hippocampal region and limbic system activity. They are considered abnormal in adults, but are perfectly normal in children up to 13 years of age. They can also be observed in individuals who are in advanced meditative states Paradoxically, theta waves are In this state, there may be a breakdown of the major transmitter systems in the CNS indicative of advanced stress, anxiety, and nervous breakdown as well.

Explanation / Answer

The first stage of sleep is characterize by theta wave which are slower in frequency and greater in amplitude than alpha waves. as sleeper moved to stage 2 theta wave activities continues intersepered with two wave phenomenon. These waves are involved in daydreaming and sleep.

Delta waves are slowest recorded brain waves in human beings. they are most active in infants and young childrens. they are associated with deepest level of relaxation.

There is decrease in Delta theta wave activities when eyes are open. they both have brain pattern of slow frequency.
