What forms the Limbic Lobe (4 parts)?
Hippocampus
Cingulate gyrus
Amygdala
Mamillary body
Function of Frontal Lobe
Cognitive function Attention Language Memory Motor function (CALMM)
Function of Parietal Lobe

Function of Insular Cortex
Visceral sensation Auditory processing Interoception Autonomic control Visual-vestibular integration
Where is the insular cortex?
Deep to the lateral fissure
Function of White Matter Tracts
Connect cortical areas
What are the 3 types of white matter tracts?
Association fibres
Commissural fibres
Projection fibres
Function of Association fibres
Connect areas within the same hemisphere
intrahemispheric
Function of Commissural fibres
Connect homologous structures in the left and right hemispheres
(interhemispheric)
Function of Projection fibres
Connect cortex with lower brain structures
(e.g. thalamus, brain stem and spinal cord)
afferent - towards cortex
efferent - away from cortex
Types of Association fibres
Short fibres
Long fibres
What is the Superior Longitudinal Fasciculus?
Long Association fibres
Connects frontal and occipital lobes
What is the Arcuate Fasciculus?
Long Association fibres
Connects frontal and temporal lobes
What is the Inferior Longitudinal Fasciculus?
Long Association fibres
Connects temporal and occipital lobes
What is the Uncinate Fasciculus?
Long Association fibres
Connects the anterior frontal and temporal lobes
Examples of Commissural fibres
Corpus Callosum
Anterior Commissure
What is the name given to projection fibres that radiate deeper to the cortex?
Corona Radiata
