“En el estudio del tálamo óptico y de la corteza cerebral se abordan las funciones anímicas, tales como la afectividad, la voluntad, la capacidad de formular una concepción del mundo, característica de cada persona.” Dr. Jose Nava Segura. 1974. Libros viejos. Librería Novo.

No entiendo y jamás entenderé porque hay gente tan envidiosa en medicina :((( porque no todos nos ayudamos? Porque no todos nos compartimos toda la info? Porque no todos somos amigos? Porque no todos nos alegramos porque todos estamos avanzando?

Mini 🧠🧵: Nervios de cráneo En medicina, es común la neurofobia (miedo basado en la idea de que la neurología es incomprensible, con secretos reservados para reptilianos). Rompamos el paradigma, es la sub más bella btw 😍 Una parte esencial es el conocimiento gral de los NC. 🔛

Hypoglossal nerve from netter

Last week, our neurosurgery residents spent the day at a hands-on teaching workshop dedicated to micro-suturing techniques. This annual workshop helps them practice essential skills for nerve repair and bypass surgeries. (1/2)

Having some mild cognitive impairment trying to remember dementia patterns on imaging?   Is looking at dementia PET scans one of your PET peeves?   Have short-term memory loss when you read about dementia imaging?   Here’s a way to remember dementia patterns so you will never forget!   Major dementia imaging patterns:   Alzheimer’s disease (AD) 🔸AD has a Nike swoosh pattern—w/decreased metabolism in parietal & temporal regions 🔸Remember if you see a Nike swoosh, just call it!   Dementia w/Lewy Bodies (DLB) 🔸Temporoparietal hypometabolism like AD but also occipital cortex, specific for DLB. DLB also extends farther to the ant. temporal cortex. 🔸Remember, regions of hypometabolism look more like an L. Lewy starts w/an L   Frontotemporal Dementia (FTD) 🔸Frontal & temporal hypometabolism as expected, but extends along anterior cingulate gyrus 🔸Anterior cingulate involvement makes hypometabolism looks like a lowercase letter f—& frontotemporal starts w/f   Posterior cerebral atrophy 🔸Can be from AD or DLB & has hypometabolism in the occipital & post. temporal lobe, sparing ant temporal lobe 🔸Sparing the ant temporal lobe makes the involvement look like a C instead of an L like DLB. So remember pCa   Vascular dementia 🔸Vascular dementia is variable, depending on the regions infarcted (V is both for Vascular & Variable) 🔸Wedged shaped regions of hypometabolism corresponding to cortical infarcts—looks like an inverted V   This list isn’t all inclusive & there can be variations or even mixed dementias   But hopefully this gives you a starting point you won’t soon forget!
