How does the brain make connections

The brain then attempts to make an internal representation of our external world.During synaptic pruning, the brain eliminates extra synapses.You conclude the book with the words, the brain is a biotic organ, embedded in a continuum of natural causes and connections that together contribute to our biological minds. bring it home for.But in humans the connections between the two are stronger.Each neuron is connected to more than 1,000 other neurons, making the total number of connections in the brain around 60 trillion!

A technique called diffusion tensor imaging (dti) gives us a tool to probe the nature of those connections.Neurons can signal to several neighbors at once.This is why teachers often have you take notes by hand or write summaries of what you've read.During this period, neurons in the newborn brain compete with one another to form lasting connections, called synapses.By sending electrical signals from nerve cell to nerve cell within a great network of connections, the brain creates thoughts as mundane as where are my keys? or as profound as i think, therefore i am. kimberley mcallister has been fascinated by the human brain since college.

This process, called multisensory integration, helps the nervous system to better understand what is happening around you.But as we grow and learn, things get a bit more stable.Synaptic pruning is a natural process that occurs in the brain between early childhood and adulthood.Scientists call the items that activate the nervous system, such as what we see or touch, stimuli.Most scientists believe that the brain forms new memories by changing the strength of these synapses.

In a sense, the neurons become wired together.
