biopsychology
biological rhythms recurring biological activities that repeat periodically
controlled by
exogenous zeitgebers- external cues which affect biological rhytms
entrainment is resetting biologocial rhytms with external cues
endogenous pacemakers- intewrnal biological clock that regulates biological rhythms
pineal gland contols the sleep wake cycle - has light sensiitve receptors when there is light inhibits melatonin and wghen it is dark stimulates melatonin which induces sleep
infradian rhythms occur in a period of over 24 hours. An example is themenstraul cycle
ultradian rhythms- ones that occur more than once in a 24 hour cycle. an example is sleep stages gfound by Deimant and kleitman
the cresearch into sleep stages has a controlled lab environemtn so has high internal validity
deimant and kleitman woke ppts up and found that 80%-90% of people in REM experienced dreams while those in NREM only 7% had a dream
supported by Hobso nand McCarley who said that dreams are electrical signallimng that occur in the REM cycle
some ppts were found to be dreaming in NREM, questioning whether REM was the stage that dreams occur
this quesrtions hobson and McCarley that dreams are in the REM stage
circadian rhythms- happen once every 24 hours. An example is the sleep wake cycle
the brain
holism- that all areas of the brain are involved inprocessing of thoights and actions
plasticity - that the brain alters structure and function due to experience
functional recovery- that after brain trauma damaged areas of the brain functions are taken over by unaffected areas
nerevous system
endocrine system
neurones
brain scans
