Thalamus Anatomy | Definition, Function & Location from Chapter 5 / Lesson 8 175K Learn what the thalamus is, where it is located in the brain, and how it functions. Discover what the thalamus does to regulate sleep and levels of consciousness. Related...
The neural activity patterns are passed on first to the cochlear nuclei, and from there through the superior olivary nuclei to the midbrain, thalamus, and primary auditory cortex. In humans the primary auditory cortex is located around a special wrinkle in the cortical sheet. The chapter ...
How does the olfactory system makes sense of scents? Why doesn't the olfactory system go through thalamus? Why is the olfactory system so sensitive? Why is the olfactory system important? How does atmospheric circulation work? Why is the human olfactory bulb smaller than those found in rodents...
How does hearing work? Think of some of your favorite sounds: the voice of a loved one, the jingle of an ice cream truck, the song you danced to on your wedding day. How exactly do all different sounds—music, laughter, birdsong, voices—travel through the air and wind through our ear...
Connected with the spinal cord, the brain stem acts to relay data between the brain’s upper parts and the spinal cord and peripheral nerves. It is composed of the thalamus, midbrain, pons, and medulla, with each part carrying out certain functions. Some of the operations under the control...
So we have this area of the brain called the thalamus, and it is getting bombarded with all sorts of sensory input all the time. But when I pay attention to something, I create a cone of attention; what we call signal-to-noise goes up. So those of you with an engineering background...
The basiclower brainconsists of thespinal cord,brain stemanddiencephalon(the cerebellum and cortex are also present, but will be discussed in later sections). In turn, the brain stem comprises the medulla, pons, midbrain, hypothalamus and thalamus [source:Health Pages]. ...

Humans have lots of hardwired reflexes like this, but as tasks become more complex, the pathway "circuitry" gets more complicated and the brain gets involved. Action potentials We have talked about nerve signals and mentioned that they are electrochemical in nature, but what does that ...
In addition, there is a large mass of neurons beneath the cerebrum, called the thalamus. This small, but critical area relays sensory impulses to the cerebral cortex. For a more detailed explanation of the brain's function, see How Your Brain Works. Scientists believe that consciousness depends...
