behavioural neuroendocrinology Flashcards
early use of electricity
electrically charged stimulus onto cortical regions of the brain could regulate and stabilise epileptic seizures
along with relieving pain when giving birth
how did the use of electricity help psychologists?
led to the idea that its not just the head but the whole body that can be stimulated by electricity.
localisation of function
specific functions are carried out in specific locations in the brain
brocas area
speech production
frontal left hemisphere
wernickes area
language comprehension
temporal left hemisphere
phineas gage
rapid change to personality following damage to frontal cortex
patient HM
suffered from seizures
treated by separating the left and right hemisphere, cutting corpus callosum
led to damage in the hippocampus, LTM stayed intact but STM was damaged
Lashleys two princibles
principle of mass action
principle of equipotentiality
principle of mass action
memories for complex tasks are stored diffusely throughout the neocortex
principle of equipotentiality
all parts of the neocortex play an equal role in the storage of memories for complex tasks
HPA
hypothalamus
pituitary gland
adrenal gland
stress access, activates the body during times of stress
critical hormone = cortisol
left hemisphere dominant
cautious
rational
organised
right hemisphere dominant
creative
emotional
adventurous
