    Transcript
    Okay. So let’s walk through some of the different senses that we can employ to engage with our environment. So unfortunately for you, you’re at your computer screen right now and you don’t get to smell how fresh I smell right now, because I smell fantastic. But if you were able to smell me right now, you’d be using your sense of olfaction. Now, we’re going to work through some examples like that of what parts of our brain are we using, what are the different senses. So one of them is somatosensation, and this is known as somatic senses of touch and tactile perception. So when you’re engaging with actual objects, you know, how is that -- how does that encoded in your brain and where is that actually happening? So sensory information is detected by several different types of receptors. So we can have mechanical, thermal. You can have a whole bunch. We’re going to go through a whole bunch of them right now. And what happens is we detect that information, that information needs to get processed and that happens in the central nervous system. So somatosensory information is carried from a sensor through a pseudounipolar nerve and synapse in the spinal cord. And then that, eventually, goes up to the brain where it’s processed. So, the nerves -- the nerve body or soma is located in an exterior body outside of the spinal cord called the dorsal root ganglion, and we’re going to show you images to highlight that. Now, I think you probably studied over and over all the different lobes of the brain. And within that tutorial, you might have heard the terms somatosensory cortex or motor cortex. And as you can see from this diagram here,. these are two bands that are found...
