Simple pinky movements = powerful brain stimulation 🧠✋ Finger and hand movement exercises — even something as small as moving the pinky — can be very helpful for people with Alzheimer’s and other cognitive decline. These movements: • Activate the motor cortex • Increase blood flow to the brain • Maintain fine motor skills • Keep neural pathways engaged Try these pinky-focused exercises: 🔹 Pinky lifts Place your hand flat on a table. Slowly lift only the pinky finger. Hold 2–3 seconds, relax. ➡

The Brain's Landscape: Sulci & Gyri Motor Lesion Mapping the Brain's Cortex. This MRI beautifully shows the peaks (gyri) and valleys (sulci) that define the brain's surface. These folds are crucial, increasing surface area for higher cognitive functions. The arrow points to a lesion located specifically on the precentral gyrus—the primary motor cortex. Damage here directly affects voluntary movement. . . #Neuroanatomy #collaboration #graduation #SulciAndGyri #Radiology #Neurology #competition #M
