A neuron known as a "grandmother cell" is one that is most sensitive to a single item.
The basic building blocks of the brain and nervous system are neurons (also known as neurones or grandmother cell ). Neurons are the cells that receive sensory information from the outside world, give motor commands to our muscles, and transform and relay electrical signals at each stage along the way. Beyond that, our interactions with them shape who we are as people. Despite this, our approximately 100 billion neurons do interact intimately with other cell types that are often referred to as glia (although it is unknown if glia actually outnumber neurons).
To visualize a neuron as a tree is a helpful analogy. Dendrites, axons, and the cell body, also known as the soma, are the three primary components of a neuron. These three components can be compared to the branches, roots, and trunk of a tree. The input from neighboring cells enters a neuron by its dendrite (tree branch). Like nerve cells tree branches, dendrites branch as they progress toward their terminals, and they even contain spines, which are leaf-like structures, on them.
