The process you are talking about is called axon guidance, by which the growth cones of developing axons are directed to reach their targets. This process depends upon a slew of cellular and molecular cues. The first axons to grow in any particular brain region are called pioneer axons and are the most dependent upon these cues. Later axons are able to ...

Axons grow but that is not same as cell is proceeding through cell cycle. Cell grows in size but there is no cell division. It is still arrested. However during this process some growth related genes are upregulated which are also upregulated in actively dividing cells.

This is a very good question. There are specific chemical signals, for instance: 1.) LRR proteins, which help signal neurons to eachother. These are transmembrane proteins which are characterised by their leucine-rich repeat. They serve as some kind of protein labels for other neurons. These proteins are also known in pathogen recognition in our immune ...

There is temporal summation of the stimuli. This is modeled in the Hodgkin and Huxley model . To imagine the whole process, you should know that in the dendrites of the neuron, electric impulses are propagating passively ( the strength of the stimuli is decreasing over distance and time), in the axon the electric impulse is active ( in the form of action ...

There is ongoing research on this topic, but there is a theory known as inhibition theory. See this from here: Directed attention fatigue occurs when a particular part of the brain’s global inhibitory system is overworked due to the suppression of increasing numbers of stimuli. This temporary condition is not a clinical illness or a personality disorder. ...

To measure single-unit neuron activity you need to use a microelectrode system, but it is very invasive. How useful the information collected depends on what you searching for. If you interest in studying the neurophysiology of neurons its good way to go. If on the other hand, you are interested actual outcomes stimulation then the average neural response is ...
