The brainstem connects the brain to the spinal cord and is essential to both survival and healthy nervous system function. In this video, I provide an overview of the structures that make up the brainstem, then I separately discuss the medulla oblongata, pons, and midbrain more in-depth.

Brown-Séquard syndrome is a rare neurological condition caused by damage to one side of the spinal cord, a situation referred to as hemisection of the spinal cord. This type of damage results in a distinct pattern of deficits due to the way different nerve tracts travel through the spinal cord. In this video, I describe the neurological deficits in Brown-Séquard syndrome and the reasons behind their characteristic pattern.

The hypothalamus and pituitary gland work together to produce and release a number of hormones that are critically important for a long list of functions in the body. In this video, I first introduce the hypothalamus and pituitary gland separately, then I describe the connections and communication between them that leads to hormone release. Finally, I discuss the hormonal stress response of the HPA axis as an example of how the hypothalamus and pituitary gland work together. To watch the vide...| Neuroscientifically Challenged

The pituitary gland is an endocrine gland that’s often called the “master gland” because it not only secretes many important hormones, but also regulates the activity of a multitude of other hormone-secreting glands and target organs throughout the body. In this video, I discuss the anatomy of the pituitary gland, the hormones it produces and releases, and the relationship between the hypothalamus and pituitary gland.

Prion diseases, also known as transmissible spongiform encephalopathies, are a group of neurodegenerative diseases that involve the accumulation of an abnormal form of a protein called prion protein into aggregates that are resistant to being broken down by brain enzymes. In this video, I discuss the general characteristics of prion diseases, including the pathophysiology, epidemiology, and prognosis.
