📋 3️⃣ Memory Tables
Table 1: White Matter Fibers
| Fiber Type | Connects | Key Function | Exam Trap |
|---|---|---|---|
| Association fibers | Same hemisphere | Connect cortical areas | Not between hemispheres |
| Commissural fibers | Both hemispheres | Interhemispheric transfer | Corpus callosum is largest |
| Projection fibers | Cortex with lower CNS | Motor and sensory pathways | Internal capsule lesions cause major deficits |
Table 2: Thalamus vs Hypothalamus
| Feature | Thalamus | Hypothalamus |
|---|---|---|
| Main role | Relay station | Homeostatic control |
| Key function | Sensory and motor relay | Autonomic and endocrine regulation |
| Related cavity | Third ventricle | Third ventricle |
| Clinical clue | Sensory loss, thalamic pain | Diabetes insipidus, temperature/appetite disturbance |
| Simple memory | “Gateway to cortex” | “Controller of body state” |
⚡ 4️⃣ Rapid Revision Points
Must Remember:
• Cerebrum has cortex, white matter, and deep grey matter.
• Central sulcus separates frontal and parietal lobes.
• Precentral gyrus is motor.
• Postcentral gyrus is sensory.
• Lateral sulcus hides the insula.
• Calcarine sulcus is related to visual cortex.
• Grey matter processes information.
• White matter connects brain regions.
• Corpus callosum is the largest commissural bundle.
• Thalamus is the main relay to cortex.
• Hypothalamus controls autonomic and endocrine functions.
• Cerebral cortex has six layers.
🩺 5️⃣ Clinical Memory Hooks
Clinical Hook:
Precentral gyrus lesion → Contralateral motor weakness
Clinical Hook:
Postcentral gyrus lesion → Contralateral sensory loss
Clinical Hook:
Internal capsule lesion → Dense contralateral motor-sensory deficit
Clinical Hook:
Thalamic lesion → Sensory loss or abnormal pain
Clinical Hook:
Hypothalamic dysfunction → Diabetes insipidus, appetite, sleep, temperature, or endocrine disturbance
