Question

As a graduate teaching assistant for your physiology class, you are required to provide an evaluation of the following examples of student work regarding sleep. No two answers can heave the same grade assigned. Sleep deprivation studies suggest it is en essenbel Bspect of homeostasis Cyclo lunuatons between phases high frequency, low amplitude waves seen in REM and the oppoeite ot each seen in NREM. REM sleep, characterized by nhloited muscls tension and nonreaponveneaa s marked by EEG activity similar to someore who is awake and alert Upcn passing trough the drowsy state, a single session of sleep is characterized by a cyclic alemation between HEM and non-REM sleep, REM, or paradoxical sicep, is characterized by leve s of brain acttuty similar to the apha rhythms seen in alert, fccused thought in the waking stale. REM waves, in compariscn to NREM are asynchronous, high trequency, and low amplitude In contrast to reet ng state8, brain wave actiwity during deep conscious thought i8haracterod by increased amplibude and decreased frequency known as an alpha rhythm. Sleep, thearized to be a homeostatic requirement, ie indicated by a 8ingular progression rrom increasingly aeynchronou8low ampitude wave activity in NREM eep to synchronous, low frequency activiny in REM seep.

Explanation / Answer

C) Upon passing through the drowsy state a single session of sleep is characterizes by a cyclic alteration between REM and NREM sleep. REM is characterised by level of brain activity similar to alpha rthyms seen in a alert, focussed thought in walking state. REM waves in comapre to NREM is asynchronous, high frequency and low amplitude.

A ) Sleep deprived studies show that it is a essential aspect of homeostasis. Cyclic phases of sleep is characterised by shift between asynchronous, high frequency, low amplitude waves seen in REM and Opposite in NREM.REM sleep is characterised by inhibited muscle tension and unresponsiveness is marked by EEG activity similar to someone who is awake and alert.

F) In contrast to the reading state, brain activity in the deep concious thought is characterised by increased apmlitude and decreased frequency known as alpha ryhtm. Sleep theorized to be homeostatic requirement, is indicated by a increased asynchronous low amplitude wave activity in NREM to synchronous high amplitude activity in REM.

All these grades are given on the basis of basic and correct information provided by the students. The more basic and complete the information, the more will be the grades.
