Olfaction is another word for the sense of smell. In this video, I summarize the process of olfaction beginning with the olfactory receptors found in the olfactory epithelium. I follow the path of olfactory information until it reaches the olfactory cortex, where most olfactory processing in the brain occurs.

In my 2-Minute Neuroscience videos I explain neuroscience topics in 2 minutes or less. In this video, I discuss synaptic transmission. I describe the synapse, synaptic cleft, release of neurotransmitter and its interaction with receptors, and the ways neurotransmitter is cleared from the synaptic cleft. Duration: 1:51.

In this video, I discuss the sense of taste and follow the path of taste information from the tongue to the gustatory cortex.

The vestibular system is a sensory system that is essential to normal movement and equilibrium. In this video, I discuss the vestibular labyrinth---the primary structure of the vestibular system, which consists of the semicircular canals, ampullae, and otolith organs. All of these are essential to the vestibular system's ability to provide the brain with information about things like motion, head position, and spatial orientation.

Alzheimer's doesn't have to be your brain's destiny, says neuroscientist and author of "Still Alice," Lisa Genova. She shares the latest science investigating the disease — and some promising research on what each of us can do to build an Alzheimer's-resistant brain. Duration: 13:47.

Patient P.S. suffered a stroke that damaged the right side of her brain, leaving her unaware of everything on her left side. If someone threw a ball at her left side, she might duck. But she wouldn't have awareness of the ball or know why she ducked. Where does consciousness come from? Michael Graziano explores the question that has vexed scientists and philosophers for centuries. [Directed by TED-Ed, narrated by Addison Anderson]. Duration: 4:56.
