role of the brain in cognitive functions and describe the impact that Phineas Gage’s accident had on revealing the brain’s role in cognitive function. Anatomy of the Brain Cognitive functions derive from the area of the brain known as the cerebrum. The cerebrum is also known as the cerebral cortex and comprises the majority of the brain ’s mass. It consists of four areas known as the frontal‚ temporal‚ parietal‚ and occipital lobes. Each area is responsible for a specific

The command center of the human nervous system is the brain. The sensory organs send information to the brain‚ which then sends output to the muscles. The largest part of the brain is the cerebrum. Underneath the cerebrum lies the brainstem‚ and behind that sits the cerebellum. The outmost layer of the cerebrum is called the cerebral cortex‚ which has four lobes. There is a frontal lobe‚ parietal lobe‚ temporal lobe‚ and occipital lobe. The brain develops from three sections known as the forebrain

The nervous system consists of the brain‚ spinal cord‚ and a complex network of neurons. This system is responsible for sending‚ receiving‚ and interpreting information from all parts of the body. The nervous system monitors and coordinates internal organ function and responds to changes in the external environment. This system can be divided into two parts: the central nervous system and the peripheral nervous system. Let ’s take a look at the central nervous system. Central Nervous System The

Tutorial: The Brain The brain was a mystery for a very long time. Modern imaging has allowed us to study the brain and locate where important functions are occurring. Please remember that the functions do not happen in just one area of the brain. Many neural layers and areas are found in any one activity that happens. But what we do know though is that some areas do appear to be predominantly involved in certain functions. We will learn about the brain in the three-part model. We’ll first look at
