What are neurons made of? What kind of neurons are in the somatic nervous system? What is the thalamus? What kinds of neurons make up the peripheral nervous system? What does the myelin sheath do in a nerve cell? What are neurons that contain a myelin sheath called?
A neural network, or artificial neural network, is a type of computing architecture that is based on a model of how a human brain functions — hence the name "neural." Neural networks are made up of a collection of processing units called "nodes." These nodes pass data to each other, j...
A neurofilament is an element of the cytoskeleton that is specific to neurons. Neurofilaments are similar to cytoskeletal elements in other cells, but they are made up of a different set of proteins. They are especially numerous in the axons, i.e., long extensions of neurons that generally t...

2. I'm sure he'll explore all the usual options for why a guy's heart starts beating so fast it pumps out air instead of blood. 我肯定他会罗列出所有的常见病因来解释为什么这个家伙的心脏跳那么快,以至于只泵气不泵血 Wait a second... there are no usual options!
has been studied is oxytocin, a hormone and neurotransmitter in the hypothalamus that has an important antinociceptive or antipain role through its binding to oxytocin receptors among other functions. This effect inhibits the trigeminal nerve neurons excitability and is also being studied right now for...
But our discovery is a little bit different. We have found a new class of RNAs that have changed how we think about cancer detection. These are relatively small RNAs, and they don't actually code for any protein. So they'...
Efferent neurons are nerve cells that convey chemical and electrical signals from the brain and spinal cord to the organs, muscles...
(2012上海卷)In terms of everyday behavior,the UCLA study found that women are far more likely than men to seek social contact when they are feeling stressed.在日常行为方面,加州大学洛杉矶分校的研究发现,当女性感到压力时,她们比男性更有...
Neurons are the cells that make up our nervous system, including the brain, spinal cord, and peripheral nerves. Neurons are usually classified as afferent neurons, those that send messages to the brain, and efferent neurons, those receiving messages from the brain. Sensory neurons are always ...
