NEURO CRASH COURSE Flashcards
What’s the anagram for the frontal lobe roles?
IM CALM
What does the IM stand for in IM CALM? Where does the execution and selection take place
Initiating Motor Function
Execution- Primary Motor Cortex
Selection- Pre-Motor Cortex
What does the C in IM CALM stand for? Where does it take place?
Cognitive executive function
Pre frontal cortex
What does the A in IM CALM stand for?
Attention (Pre-frontal cortex)
What does the L in IM CALM stand for?
Language
Where is Brocas area found and what is it used for?
Frontal cortex and the motor part of speech production.
Where is the central sulcus found?
Between the frontal and parietal lobe
What lies between the parietal and occipital lobe?
Parieto-occiptal sulcus
What fissure lies between the temporal and frontal/parietal lobe?
Lateral fissure
What separates the right and left hemisphere?
Longitudinal fissure
What are the name of neurones seen in cortical column?
Small Pyramidal neuron, Granule (Stellae) neuron, Large pyramidal neurones
What is the function of the primary cortices?
Receiving, processing, execution
What is the function of secondary ( association) cortices
Integration and association
Where is the primary motor cortex located?
Pre central gyrus
What is the primary motor cortex responsible for?
Fine, descrete , precise voluntary movement
What is the supplementary motor area used for?
Externally cued movements ( Like kicking a ball or picking up a glass
What is the pre central motor area used for?
Internally cued complex movements like speech generation
What is the anagram for Prefrontal cortex?
APPS
What are the respective words for the anagram APPS?
A- Attention
P-Personality
P- Planning and decision making
S- Adjusting Social behaviour
Using APPS what would a prefrontal cortex lesion lead to?
Lack of attention
Personality change
Inability to plan actions
Inappropriate behaviour
What is the way to remember the 4 main roles of the parietal lobe?
Sensation- touch, pain, temperature, pressure, vibration
Sensory aspect of language
Sixth Sense- Proprioception
Where is brocas area found? And what would a lesion in. this area lead to?
Left frontal lobe, Expressive Aphasia
What are the 3 types of white matter tracts?
Association fibres, Commissural fibres and projection fibres?
What type of white matter tract is Short U Fibres ? What does it connect?
Association and they connect gyri
What are the main 4 types of long fibres?
Superior longitudinal fassiculus, Inferior longitudinal fassiculus, Arcuate Fassiculus and Unicate Fassiculus
What connects the frontal and occipital lobe?
Superior Longitudinal Fassiculus
What connects the frontal and temporal lobe?
Arcuate fassiculus
What connects the temporal and occipital lobe?
Inferior longitudinal fassiculus
What connects the anterior frontal lobe and temporal lobe?
Unicate fassiculus
What is the function of commissural fibres?
Connect the left and right hemispheres of the brain
What are the main 2 commissural fibres?
Corpus Callasum and Anterior commisure
What is the function of the projection fibres? One to remember
Connect cortex with lower brain structures, Corona Radiata
