limbic system Flashcards
at the temporal lobe
match each brain of the ‘truine brain’ with its defintion:
a) reptilian brain
b) mammal brain
c) human brain
- limbic system
- language, abstract thought, imagination
- fight or flight
- autopilot
- emotions, memories, habits
- neocortex
- decisions
- brain stem and cerebellum
- reason, rationalizes
reptilian brain:
- brain stem and cerebellum
- fight or flight
- autopilot
mammalial brain:
- limbic system
- emotion, memories, habits
- decisions
human brain
- neocortex
- language, abstract thought, imagination
- reason, rationalizes
limbic system is described as…
emotional system
which are parts of the limbic system:
- medulla
- hypothalamus
- parietal cortex
- fornix
- cerebellum
- midbrain
- cerebrum
- hippocampus
- brainstem
- mammillary bodies
- pons
- temporal cortex
- amigdala
- fonix
- basal ganglia
- cingulate gyrus
- coccygeal regions
- occipital cortex
- thalamus
- corpus callosum
- amygdala
- hippocampus
- hypothalamus
- thalamus
- fornix
- mammillary bodies
- cingulate gyrus
- corpus callosum
what are the amigdala functions:
- connects left and right hippocampus
- salience vigilance (monitor environment for signs that have a piece of significant information)
- persude hypothalamus to do things
- allows hippocampus to communicate with other structures within the limbic system
- tells thalamus how a particular situation makes us feel
- fear and aggression
- helps hippocampus function
- spatial learning
- learns about cues
- thermoregulation
- hunger, thirst…
- communicate information about a learned situation
- tells thalamus how a particualr situation ameks us geel
- fear and aggression
- larns about cues
- communicate information about the learned situation
- salience vigilance: monitor environment for signs that have a piece of significant information
what are the fornix main functions:
- connects left and right hippocampus
- salience vigilance (monitor environment for signs that have a piece of significant information)
- persude hypothalamus to do things
- allows hippocampus to communicate with other structures within the limbic system
- tells thalamus how a particular situation makes us feel
- fear and aggression
- helps hippocampus function
- spatial learning
- learns about cues
- thermoregulation
- hunger, thirst…
- communicate information about a learned situation
- connect left and right hippocampus
- allows hippocampus to communciagte with other structures within the limbic system
- ## helps hippocampus function
hypothalamus main funsctions are:
- connects left and right hippocampus
- salience vigilance (monitor environment for signs that have a piece of significant information)
- physiological output of the nervous systmem of the brain
- persude hypothalamus to do things
- allows hippocampus to communicate with other structures within the limbic system
- tells thalamus how a particular situation makes us feel
- fear and aggression
- helps hippocampus function
- spatial learning
- learns about cues
- thermoregulation
- hunger, thirst…
- communicate information about a learned situation
- physiologicla output of the nervous system of the brain
- spatial learning
- thermoregualtion
- hunger, thirst…
medial thalamus and mamillary bodies
choose which are the symptoms of Korsakoff’s syndrome:
- Personality change
- Spatial neglect
- Confabulation
- Expressive aphasia
- Sensory disturbances
- Anterogade amnesia
- Sleep disturbances
- Lost of spontaneous interactions
- Inability to focus on a task
- Dysmetria
- retrogade amnesia
- Difficulty to complete a task
- confabulation
- anterogade and retrogade amnesia
confabulation is the confusion between memory and imagination
most common cause of Korsakoff’s syndorme is…
vitamin B1 (thiamine) deficiency
mainly saw in chronic alcholism
deifne the disease ‘amygdala hijak’
intense emotionalr eaction that’s put of proportion to the circumstance
olfatory memories are a strong emotional memory stimulus: true or false
true.
they are connect to limbic system
olfatory pathways goes through thalamus: true or false
false
