Central nervous system stimulants — Drugs that stimulate the nervous system (eg, amphetamine, methylphenidate) have great effects on both the quality and architecture of sleep.
●Effects on Sleep quality – CNS stimulants delay sleep onset and increase wakefulness during the sleep period.
●Effects on Sleep architecture – CNS stimulants prolong light sleep (Stage N1) and decrease both stage N3 and REM sleep.
●Side effects: daytime sleepiness due to reduced sleep. ephedrine or pseudoephedrine, which are similar in chemical structure to amphetamine. These agents have not been studied, but they probably also disrupt sleep.

We believe this project will show causative effect and correlation between sleep disruption and delirium. This project will have the potential to impact all three of the primary goals for our organization: Patient satisfaction, quality and financial strength. The exciting part of this project is that each phase has the potential to impact and improve patient care independent of the other phases. The primary goal for this project is to make a difference in the lives of our patients through innovation and improved

We all would like to forget something but is not as simple as that shapes your existence. In “The Attic of the Brain” by Lewis Thomas talks about how humans want to control every aspect of the brain. He states “There is no delusion more damaging than to get the idea in your head that you understand the functioning of your own brain.” Essentially is only a delusion humans have and can never hope to achieve and only will hurt us, while this may be true or not who’s to say. He also talks about how we may want to “to take charge, guiding your thoughts”, like to repress some our memories like in a “trapdoor”.

Transcranial magnetic stimulation (TMS) is a non-invasive tool for the electrical stimulation of neural tissue, including cerebral cortex, spinal roots, and cranial and peripheral nerves. TMS can be applied as single pulses of stimulation, pairs of stimuli separated by variable intervals to the same or different brain areas, or as trains of repetitive stimuli at various frequencies. Single stimuli can depolarise neurons and evoke measurable effects. Trains of stimuli (repetitive TMS) can modify excitability of the cerebral cortex at the stimulated site and also at remote areas along functional anatomical connections. Transcranial magnetic stimulation might provide novel insights into the pathophysiology of the neural circuitry underlying neurological and psychiatric disorders, be developed into

Nervous Conditions is a partially autobiographical novel by Zimbabwean author Tsitsi Dangarembga that takes place in Rhodesia in the late 1960s and early 1970s. It focuses on the themes of race, class, and gender through the eyes of Tambu, the young female protagonist. The title references Jean Paul Sartre 's introduction to Frantz Fanon 's 1963 book The Wretched of the Earth, in which he writes, "the status of 'native ' is a nervous condition introduced and maintained by the settler among the colonized people with their consent. " Dangarembga expands Fanon 's exploration of African people oppressed by a colonial regime by incorporating the gender-specific role of black women, who are arguably doubly oppressed. The women in Dangarembga 's novel grapple with "nervous conditions" borne from years of colonialism as well as the continued oppression under the Shona power system.
