Limbis System Flashcards
What system forms the inner border if the the, cortex part of cerebrum (telencephalon)
The limbic system
Where is the lambic system
Found on inner/medial surface of two hemispheres
Situated in medial temporal lobe and in/around thalamus
T/f some part of the limbic system are part if subcortex (subcortical structures) , so are technically part of diencephalon
True
What regulates emotion and emotional responses to new and old situations
Limbic system
What supports autonomic functions and hormonal responses
The limbic system
What forms and encodes new memories; attach emotional salience to memories
Limbic
Support new learning
Limbic
Lots of connections to cotex, thalamus, and hypothalamus
Limbic
Sends info to frontal lobe so that Reason can override emotions
Send info to subcortex to trigger autonomic
Limbic
Olfactory bulb
Sense if smell, allowing for adaptation and response to environment
Cingulate gyrus/cortex
Transport emotions, memories to /from prefrontal cortex (efs) to support behavioral decision-making, control, and regulation
Support in autonomic functions (heart rate, blood pressure )
Orbitofrontal prefrontal cortex
Help decide and direct
Assists in the control (or inhibition) of behaviors and decision-making
Fornix
Transport from hippo to hyp
Transport/connections between hippocampus and mammillary bodies ( which end up going to the hypothalamus, to engage autonomic)
Prefrontal cortex
Executive function
Self regulation, inhibition, stratgeically plan and organize, adapt cognitive effort, initiate
Parahippocampal
Modulate emotion
Regulate emotion
Amygdala
Attach emotional significance, tone, memory to sensory info
Most critical structure on how you modulate/experience/ response to/intensity of emotion
Hippocampus
Form/encode new memories
Mammillary body
Transport/to front thalamus, hypothalamus, to engage autonomic system, hormones
Limbic system connection to prefrontal cortex
Decision making/inhibition
Link thinking brain with emotional brain
Override emotional impulsive drives
Help mediate motivation
Limbic system connection to temporal lobe
Memory formulation/storage
Limbic system connection to hypothalamus
Autonomic, hormonal response
Trigger physical reaction (fight/flight)
Exert control over endocrine system, appetite, sexuality
Corpus callosum
Connect two hemispheres and made if myelinated axons (tracts)
When fight or flight go to long term memories- fornix- mammillary body and it’s partner trigger …
Autonomic nervous system
Fornix either get info and go through corpus callusm, cingulate gyrus, frontal lobe ( orbitofrontal prefrontal cortex) orrrr
Fornix gontonterminakbenf of mammillary body- get hypothalamus to trigger autonomic system
Hippocampus
Encode long term memory
