Biopsychology Flashcards
Fight or flight
Should:
Taylor - Females = Tend/Befriend
Gray - ‘Stop look and freeze’
Localisation of Function
Must:
Broca - speech (Tan)
Wernicke - understanding
Phineas Gage - frontal lobe, personality, decisions, social
Peterson - Brain scans (Cog Neuro) finding Wernicke active when listening, Broca active when reading.
Should:
Dronkers - Also looked at Tan, found other areas damaged.
Dejerne - Case study (unable to understand written words), but no damage to visual cortex or Wernicke’s. Instead, just the connection/coms.
Danelli - Patient EB.
Lashley - Law of equipotential (learning is COMPLEX function)
Hemispheric lateralisation & split brain research
Must: Sperry & Gazzaniga - language LH, tactile RH, drawing dominant LH.
Should: Patient EB - LH removed so RH took over to speak
Plasticity and Functional Recovery
Must:
Maguire - (Plasticity) Taxi drivers’ hippocampus.
Hubel & Wiesel - (FR) Sewed one cat’s eye shut, visual cortex continued process onto other eye.
Should:
Kuhn - Lab > Quasi (Maguire)
Elbert - Children > Adults
Lashley - Law of equipotential
Ways of studying the brain
Broca - Post mortem success
Endogenous Pacemakers and Exogenous Zeitgebers
Ralph - SCN 21hrs (abnormal) <-> 24hrs (normal)
DeCousey - No SCN = Die early
Campbell & Murphey - Blue light on knee delaying melatonin
Infradian rhythms
Menstrual (increase oestrogen for egg development and increase progesterone for thick womb).
Reinburg - 3 months, menstrual cycle 25.7 days
Stern & McClintok - Pads with pheromone, 68% experienced changes to their menstrual cycle, closer to pheromone donor.
Ultradian rhythms
Kleitman or Ercission - Peak performance cycles (Basic Rest Activation Cycle)
Circadian Rhythms
Must: Siffre - 6 months in cave = 25-30hrs SWC
Should:
Aschoff & Wever - similar findings w Bunkers
Endocrine system role
Control/regulate the vital physiological processes via hormones in the bloodstream.
