The diagram provided shows an
outline of the major parts of the human brain. Which part of the cerebral cortex
contains the hearing center, which is involved in receiving auditory
information? (A) The frontal lobe, (B) the
occipital lobe, (C) the temporal lobe, (D) the parietal lobe.
To answer this question, we will
start by defining the cerebral cortex. Then, we’ll define the major parts
of the cerebral cortex to recall which part is responsible for receiving auditory
information.
The cerebral cortex is the outer
layer of the cerebrum that has folds and grooves, which give the brain its notable
wrinkled appearance. Each hemisphere of the cerebral
cortex is divided into four major lobes, which are the frontal lobe, the temporal
lobe, the occipital lobe, and the parietal lobe. Let’s take a closer look at the
function of each of these lobes.
The frontal lobe is important for
managing higher-level cognitive functions that support our ability to achieve a
goal. This means these lobes are
responsible for a wide range of actions, such as voluntary movements, language
production, decision-making, speech, short-term memory, and reasoning.
The parietal lobe contains the
somatosensory map of the body, which helps it to carry out two main functions. One of the functions is
somatosensation, which uses areas of the parietal lobe to process touch sensations,
such as pressure, pain, and temperature. The other function is
proprioception, which uses areas of the parietal lobe to sense the orientation and
location of our body parts. This helps us understand where our
bodies are located in space.
The occipital lobe is the visual
processing center of the human brain. This is because the occipital lobe
houses the visual cortex, which processes information from the eyes and interprets
this information into the images that create our perception of the world. Other parts of the occipital lobe,
such as the visual receiving and association areas, process visual images of
language and interpret this imagery.
The temporal lobe has several
functions, because it contains the centers for hearing and memory. At the top of each temporal lobe,
there is an area responsible for receiving auditory information from the ears. Other parts of the temporal lobe,
like the underside of each lobe, play a crucial role in forming and retrieving
memories, including those that are tied to emotions or auditory information.
After reviewing all of the
different lobes of the cerebral cortex, we can conclude that the part of the
cerebral cortex that contains the hearing centers and is involved in receiving
auditory information is the temporal lobe.
Now, we have all the information we
need to answer the question. The part of the cerebral cortex
that contains the hearing center, which is involved in receiving auditory
information, is the temporal lobe.
