Your patient presents with nystagmus, dysphagia, ipsilateral facial numbness, and contralateral arm and leg numbness. You remember about the nucleus ambiguous, vestibular nuclei, and spinothalamic tract. Is it the lateral medullary syndrome? We give you the scoop of the medulla and its cranial nerves 9-12.

Move your eyes to the right. Now to the left, please. Horizontal eye movements are unique features and functions of the pons. We take a closer look at the relationship between cranial nerve 6 and 7, and the trigeminal sensory nuclei and its motor nucleus. Click here.
Look up to the sky. Now stare at the ground. While the pons affect your horizontal eye movements, the midbrain is important for vertical eye movements. But that is not all. We take you on the pathways that cross the roads of the red nucleus, periaqueductal grey, superior/inferior colliculus and substantial nigra. Click here.
Without oxygen, the brain can’t get its job done. So to ensure an unobstructed blood flow, several regulatory mechanisms are in place even at the expense of other organs if necessary. Click here.
“I forgot to take my keys with me!” If you are experiencing memory loss, your cerebral cortex might be causing the problem. Often the target of Alzheimer’s dementia, the cortex can be vulnerable to neurodegeneration. We catch you up on the diseases and give you a brief histology course. Click here.
The CNS and its cerebrospinal fluid are in an enclosed system to protect them from external attacks. The connective tissue membranes, collectively named, meninges, provide just that. Click here.
We take you on a path to learning the basic neuroanatomy that will prepare you for subsequent neurological concepts. We call it the basic “plumbing” of neuroanatomy. Click here.
“Hey doc, the lateral side of my legs feel numb. Otherwise, my legs are normal.” What could be causing this? Learn more about the nerve root lesions and plexopathies in the brachial and lumbosacral regions. Click here.
Lab values, CT scans, MRI scans are fancy—and expensive— but neurologic history and physical examination can take you to the next level as a doc. We focus on the interpretation of the neurologic examination. Click here.
Close your eyes and stand still. Can you do it without falling? Imbalance, or shall we say gait instability, is impacted by areas of the central and peripheral nervous system. To have a steady balance, one must have both nervous systems working at a near normal capacity. Click here.
The impression says, “left sided tumor in the temporal region.” CT and MRI studies have revolutionized the field of neurology. Acute or chronic neurological problems can often be localized and confirmed by them. How do we use them properly? Click here.
Ouch, Charlie bit my finger! Your pain receptors shoot a message to the brain that something caused pain. Your sensory receptors convey information to the brain about touch, temperature, pain, and proprioception. We talk about the pathways and clinical presentations associated with them. Click here.
Horizontally cut the spinal cord and you will find an inner H-shaped zone of gray matter and an outer zone of white matter. Dig deeper and see the ascending and descending pathways that communicate information through the segments of the spinal cord. Click here.
Where is the main processing center for information traveling to the cerebral cortex? If you were thinking of the thalamus, you are correct. That is one of three structures that form the subcortical anatomy. So what are the other two? Click here.
Just because something is small doesn’t mean it can’t be powerful. The cerebellum is one example. It contains more than 50% of all CNS neurons. We elucidate some of the lesions of the cerebellar anatomy and the distinct clinical syndromes. Click here.
