If neurons connect randomly, how do signals go to the right places in the brain? Neurons don't divide, but new neurons are created from stem cells. How do these new neurons eventually become used in the brain? Information comes into neurons via: a. dendrites b. axons c. myelin ...
hedgehog and fibroblast growth factor-8 followed by glial cell-derived neurotrophic factor, brain-derived neurotrophic factor, ascorbic acid, and dibutyryl cyclic AMP resulted in smaller grafts than those without these treatments, and survived as DA neurons in a monkey brain as long as six months....

The researchers from Peking University used a high-speed dual-view two-photon microscope they developed to realize calcium ion imaging of up to 9,000 neurons in adult SCN slices, and then they leveraged artificial intelligence (AI) methods to understand meanings of those signals as a whole. The...
How do afferent neurons enter the spinal cord?Spinal Cord:The spinal cord is long thing tube made of bundles of nerves that travel to and from the brain to the rest of the body. The spinal cord can be divided in to a dorsal part (toward the back of the body) where the sensory ...
To understand how neurons transmit signals, we must first look at the structure of the cell membrane. The cell membrane is made of fats or lipids called phospholipids. Each phospholipid has an electrically charged head that sticks near water and two polar tails that avoid water. The phospholipids...
"The animal is pushing because it wants a reward, and the locus coeruleus provides critical signals to say, push now, because the reward will come," Sur says. The researchers also found that the neurons that generate this noradrenaline signal appear to send most of their output to themotor ...
The means of travel within and between neurons is different because: a) electrical signals move impulses within the neuron, while chemical signals move the impulses between neurons. b) chemical signals move the impulses within...
Describe how nerve signals are propagated along axons and between different neurons. Describe the location of the central and peripheral nervous systems. Describe the components of the autonomic nervous system. Explain how papillae, taste buds, taste cells, taste receptors, and specific nerves ...
Output layer nodes function in the same way as hidden layer ones: output nodes sum the input from the hidden layer, and if they reach a certain value, the output nodes fire and send specific signals. At the end of the process, the output layer will be sending a set of signals that in...
