Neuroscientifically Challenged

Ion channels are proteins found in the cell membrane that allow charged particles called ions to move into or out of a cell. In this video, I discuss the structure, function, and dysfunction of ion channels. To watch the video, click the "continue reading" link below.

Aphasia is a language disorder caused by damage to areas of the brain involved in producing or understanding language. In this video, I discuss several of the most common aphasia syndromes: Broca's aphasia, Wernicke's aphasia, conduction aphasia, and global aphasia.

For much of the history of neuroscience, glial cells were treated like structures that existed mainly to support and hold neurons together. In fact, the term glia comes from the Greek word for “glue,” reflecting this early assumption about their role. Over the last several decades, however, our understanding of glial cells has changed dramatically. We now know that glial cells a...
