Cortical Layers and Functions
- The six cortical layers have distinct cell types and functions, with layer 5 projecting to the body and basal ganglia.
- Layers 4 and 6 handle thalamocortical communication, while layers 2 and 3 manage cortico-cortical connections.
Frontal Lobe Organization
- The frontal lobe has distinct functional areas, ranging from primary motor control to higher-level cognitive processes.
- Understanding this organization helps localize lesions based on clinical findings, like leg weakness from midline lesions.
Midline Meningioma Case
- A patient presented with lower extremity weakness after multiple spinal imaging studies.
- Central imaging revealed a large midline meningioma, highlighting the need for thorough evaluations.
