Discuss the influence of endogenous pacemaker and exogenous zeitgebers on one or more biological rhythms (24 Marks) Introduction This essay will outline and evaluate the role that endogenous pacemakers (ep’s) or internal clocks have on our biological cycles. It will also consider exogenous zeitgebers (ez’s) or external timekeepers. The two cycles to be considered are circadian and ultradian.

study‚ which combines neurosciences and marketing. It studies consumers’ sensorimotor‚ cognitive‚ and affective response to marketing stimuli‚ by using medical technologies‚ such as functional magnetic resonance imaging (fMRI)‚ electroencephalography (EEG) and steady state topography (SST). Researchers aim to measure brain activity in response to certain stimuli and changes in consumers’ physiological state (heart rate‚ respiratory rate‚ galvanic skin response) to learn and understand what actually happens

A lot of Dement’s theories about sleep deprivation resulted from this marathon. Based on EEG readings from the end‚ Dement believes Gardner was in a sleepwalking state some of the time. This is because people lose motivation and the ability to control what they are doing. Sleep deprivation also leads to microsleeps. Microsleeps are “nod offs”

Long-acting amide local anesthetic agent like racemic mixture bupivacaine has an intermediate asymmetric carbon chain linkage. Because of this asymmetric carbon atom as chiral centre‚ it exhibits stereo isomerism.In the commercial presentation of this local anaesthetic there is a 50:50 proportion: levobupivacaine‚ L (-) isomer‚ and dextrobupivacaine D (+) isomer
