The response time is the time that elapses between the moment in which the nervous system is subjected to a stimulus and
the moment in which the organism's response to that stimulus is realized, following the processing of information by the brain.
In humans, the response time to visual stimuli is typically between 150 and 300 milliseconds.
The human brain consists of about one billion neurons. Each neuron forms about 1,000
connections to other neurons, amounting to more than a trillion connections.
Yet neurons combine so that each one helps with many memories at a time, exponentially increasing the brain’s
memory storage capacity to something closer to around 2.5 petabytes (or a million gigabytes).
