The authors have performed a potentially valuable new kind of analysis in connectomics, mapping to an interesting developmental problem of synaptic input to sensory neurons. While the analysis itself ...

Note: Some students might have trouble discussing this topic because they may have a family member with Alzheimer's disease. Model a nerve cell. Explain to students that the nervous system functions ...

In mammalian neurons, the axon initial segment (AIS) electrically connects the somatodendritic compartment with the axon and converts the incoming synaptic voltage changes into a temporally precise ...

Stay up to date on the latest science with Brush Up Summaries. Nerve cells, or neurons, are the basic functional units of the nervous system. Multiple interconnected neurons form a neural circuit and ...

A typical neuron is composed of three main structures: the cell body, axon, and dendrites. The cell body is where most of the cellular organelles are located, including the nucleus, which contains the ...

Researchers have made new progress in understanding how cannabinoid receptors (CB1Rs), the proteins that detect the active components of marijuana, are controlled in the brain. Researchers at the ...

When a person thinks, speaks, eats, walks, or just sits comfortably with all bodily systems functioning normally, the billions of cells that make up the brain and the rest of the nervous system are ...
