Question

Outline two mechanisms by which information flow between two neurons in an adult can increase.

Step-by-Step Solution

Answer

Information flow can increase the number of synapses between the neurons or increase the strength of the existing synaptic connections. These are the two mechanisms that increase the information flow between two neurons in an adult.

Step 1: Flow of information through the synapses

A synapse is a link between two neurons or a target or effector cell, such as a muscle cell. It allows electrical or chemical impulses to be transmitted. Presynaptic and postsynaptic neurons create the synapse. 

Step 2: First mechanism for increasing the information flow between the neurons

In adults, increasing the number of synapses leads to increases in the flow of information from neurons. Motor skills like writing and walking are often learned through repetition. Anyone can do these activities without having to remember the specific required steps consciously. 

Many tasks are completed correctly, such as skills and techniques for learning. It indicates that cellular systems are involved in the ability to ride a bicycle. This is substantially comparable to those in charge of brain development. Neurons form new connections in such instances.

Step 3: Second mechanism for increasing the information flow in neurons

Neurons information flow increases when the strength of the existing connection is increased, such as memorizing contact information, dates, and other information like places.

Exposure to the relevant item may be primarily dependent on changes. It leads to changes in the tensile strength of pre-existing neural connections.
