Answer: You are sitting at a Mexican restaurant waiting for your food. The waiter brings a very hot plate, telling you to be careful about touching it. You touch it anyway, producing a pain sensation in your fingers, a withdrawal of your hand, and an auditory comment of what you are thinking. This scenario represents an <u>involuntary</u> act on the neuronal circuit.
Explanation:
<em>The neurons</em> of an organism form <u>numerous circuits </u>that originate very complex networks. The nervous current that circulates through them produces two <u>types of acts:</u>
- Involuntary Acts. (reflex arc)
They are<u> fast, automatic, and are performed without the action of the brain</u>. In a reflex act, sensitive information only reaches the spinal cord, so the <em>response is automatic</em>. They are the ones that are performed when a quick response is needed.
They are <u>varied, changing, and more elaborated.</u> Voluntary acts are carried out in a conscious way and are <em>controlled voluntarily</em>. Not all are a consequence of the reception of an external stimulus, since t<u>hey can be produced directly in the cerebral cortex</u> without the need for an external stimulus.

Behavioral
neuroscientists use non-invasive brain imaging techniques for various uses such
as: detecting brain impairments or abnormalities, studying brain anatomy and investigating
which areas of the brain show most activity when performing particular tasks or
activities. Some non-invasive brain imaging techniques include fMRI, MRI and
EEG.
