Subcortical White Matter Made Simple | Key Tracts and Functions

For more cadaveric images and question banks, visit https://bootcamp.com/med-school White matter can feel abstract, so this lesson keeps it clear. We cover what white matter is, how myelin speeds signals, and how to classify tracts into commissural, projection, and association groups. You will learn the big landmarks you see on scans and why they matter clinically. We walk through the corpus callosum parts, forceps major and minor, corona radiata, internal and external capsules, and cerebral peduncles. Then we map long association tracts like the cingulum, arcuate fasciculus, uncinate fasciculus, superior and inferior longitudinal fasciculi, and the inferior fronto occipital fasciculus. There is a short case at the end on conduction aphasia, linking a lesion of the arcuate fasciculus to impaired repetition with intact comprehension and speech production. You will see how DTI helps confirm the diagnosis. ⏱️ Time Stamps 0:00 – Intro and why white matter matters 0:25 – Case study: patient with speech repetition issues 1:04 – Learning goals for the lesson 1:25 – What is white matter? Myelin and axons explained 2:34 – How myelin speeds up communication 3:15 – White matter = myelinated axons 3:33 – Three categories: commissural, projection, and association fibers 4:38 – Commissural fibers: corpus callosum overview 5:02 – Parts of the corpus callosum: rostrum, genu, body, splenium 5:51 – Anterior and posterior commissures 6:29 – Forceps minor and forceps major 8:00 – Easy way to remember forceps major vs minor 8:23 – Projection fibers: corona radiata, internal capsule, external capsule 9:28 – Cerebral peduncles and descending tracts 9:52 – Lateral dissection: corona radiata and external capsule 10:58 – Internal capsule: anterior limb, genu, posterior limb 11:57 – Why the internal capsule matters clinically 12:19 – Association fibers: short vs long 13:15 – Cingulum tract and its C-shape 14:15 – Superior longitudinal fasciculus 14:32 – Inferior longitudinal fasciculus 14:47 – Uncinate fasciculus 15:07 – Arcuate fasciculus (Broca ↔ Wernicke) 15:51 – Inferior fronto-occipital fasciculus (deep layer) 16:10 – Case study revisited: conduction aphasia and arcuate fasciculus lesion 17:35 – Practice question 1: uncinate fasciculus and corona radiata 18:38 – Practice question 2: internal capsule and forceps major 20:13 – Practice question 3: inferior fronto-occipital fasciculus and short association fibers 21:26 – Summary and key takeaways This lesson is especially helpful for medical students, or anyone reviewing for anatomy exams.
