Answer:
The cells of the visual cortex are neurons in the brain's visual system that respond to particular features of a stimulus.
Explanation:
These neurons respond to stimuli presented to both eyes. Simple cells receive innervation directly from thalamic cells and respond to light stimuli with defined orientation and with specific configuration and location in the visual field. Complex cells also respond to the orientation parameter.
These cells trigger action potentials when the visual stimulus appears within their receptive field.

Once the alcohol goes into our system, an ounce of it is process for a period of one hour.
The first stop happens in the stomach where absorption through the gastric lining and bloodstream occurs. Stronger drinks are absorbed more quickly. The second stop happens in the brain where its function decreases/ is increasingly impaired as the BAC or blood alcohol content grows. The third stop will be in the heart. However, it should be noted that it does not receive any physical alcohol, but its effects on the heart are strong. Alcohol is a vasodilator which means it causes blood vessels to dilate. This indicates more blood flow through the body-- but lowers the overall blood pressure. The fourth stop will be in the kidneys where blood is filtered. The fifth stop will be in the bladder where it will excreted from the body. Lastly, the liver is where the rest of alcohol left in your system is broken down. This process is known as metabolizing. The chemical that remains after metabolization is acetaldehyde and the body gets rid it by further metabolizing it into carbon dioxide and water.
Therefore, an ounce of alcohol is processed in our body for 60 minutes or one hour.
