Human brain structure is composed of three main parts: the forebrain, What is the main idea

Human brain structure is composed of three main parts: the forebrain, midbrain and hindbrain, each with multiple parts.

The Cerebrum: Also known as the cerebral cortex, the cerebrum is the largest part of the human brain, and it is associated with higher brain function such as thought and action. Nerve cells make up the gray surface, which is a little thicker than our thumb. White nerve fibers beneath the surface carry signals between nerve cells in other parts of the brain and body . Its wrinkled surface increases the surface area, and is a six-lay ered structure found in mammals, called the neocortex. It is divided into four sections, called “lobes”. They are; the frontal lobe, the parietal lobe, the occipital lobe and the temporal lobe.

Frontal Lobe – The frontal lobe lies just beneath our forehead and is associated with our brain’s ability to reason, organize, plan, speak, move, make facial expressions, serial task, problem solve, control inhibition, spontaneity , initiate and self-regulate behaviors, pay attention, remember and control emotions.

Parietal Lobe – The parietal lobe is located at the upper rear of our brain, and controls our complex behaviors, including senses such as vision, touch, body awareness and spatial orientation. It play s important roles in integrating sensory information from various parts of our body , knowledge of numbers and their relations, and in the manipulation of objects. Portions are involved with our visuospatial processing, language comprehension, the ability to construct, body positioning and movement, neglect/inattention, left-right differentiation and self-awareness/insight.

Occipital Lobe – The occipital lobe is located at the back of our brain, and is associated with our visual processing, such as visual recognition, visual attention, spatial analy sis (moving in a 3-D world) and visual perception of body language; such as postures, expressions and gestures.

Temporal Lobe – The temporal lobe is located near our ears, and is associated with processing our perception and recognition of auditory stimuli (including our ability to focus on one sound among many , like listening to one voice among many at a party ), comprehending spoken language, verbal memory , visual memory and language production (including fluency and word-finding), general knowledge and autobiographical memories.

A deep furrow divides the cerebrum into two halves, known as the left and right hemispheres. And, while the two hemispheres look almost sy mmetrical, each side seems to function differently . The right hemisphere is considered our creative side, and the left hemisphere is considered our logical side. A bundle of axons, called the corpus callosum, connects the two hemispheres.

What is the main idea of the passage?

A.   The description of surface carry signals between nerve cells in other parts of the brain and body .

B.   The explanation about A bundle of axons, called the corpus callosum, connects the two hemispheres.

C.    The overview about the structure and function of the human brain.

D.   The findings of the important roles of parietal lobe in integrating sensory information from various parts of our body.

E.    The argument of the perception and recognition of auditory stimuli in human brain.
