Evaluate Ultradian rhythms.
+Kleitman and Dement, used EEG's and woke up participents, 80% dreamt REM, 7% dreamt at NREM, +Ericssen, RLA, violinists, -Individual differences, children are easily disrupted.

Outline Endogenous Pacemakers.
The pineal gland releases hormones, there are light receptors connected and releases melatonin. The Superchiasmatic Nucleas, regulates the release of melatonion through interconnecting pathways.

Evaluate Endogenous Pacemakers.
+Ralph, mutant hamsters, removed foetal tissue, 20 hours, -Folkard, university student with no access to daylight for 25 days in a lab settings, extended to 30 hours.
3 of 11
Outline Exogenous Zeitgebers.
Entrainment, light alters the levels of melatonin levels. Social, with parent's support their cycles are created. 6-16 weeks.
4 of 11
Evaluate exogenous zeitgebers.
+Miles, a blind boy couldn't reset, 25 hour cycle. +Burgess, exposed to light when travelling EW, -Artic, keep a consistent cycle.
5 of 11
Outline localisation and the function of the brain.
Holistic- a whole, reductionist- seperated into sections. Frontal lobe, motor, somatosensory, parietal, occipital and temporal. Broca's area- frontal lobe, speech production, Wernicke's area- temporal lobe, language comprehension.
6 of 11
Evaluate localisation and the function of the brain.
+Phineas Gage, +Peterson, brain scans showed that Wernicke's area was active during listening task and Broca's during reading, -Lashley, rats brains, -Plasticity.
7 of 11
Outline Plasticity and functional recovery.
Overtime the brain creates new pathways and grows. It can recover itself through axon sprouting, blood vessel reformation and recruitment of homologus. Secondary pathways take on tasks, normal brain function.
8 of 11
Evaluate Plasticity and functional recovery.
+Macguire, taxi drivers take the knowledge and have larger grey matter, +Hubel and Wiesal, removed cat's eye, -Negative consequences.
9 of 11
Outline hemispheric laterization and research.
The brain is split into two hemispheres, Sperry- split screen, on the right eye they could see and say but on the left they couldn't say, but could draw it.
10 of 11
Eva,uate hemispheric laterization.
+Standardised research, 1/10th of a second, +Pucetti, more research, 2 function differently, -No control group, cause and effect.
