Summary of Part 1 Basic Mechanisms PowerPoint Presentation free Biology Diagrams The cerebral cortex lobes include the parietal, frontal, occipital and temporal lobes. It is divided into four lobes that each have a specific function. For example, there are specific areas involved in movement and sensory processes (vision, hearing, somatosensory perception (touch), and olfaction). Other areas are critical for thinking These lobes are called the frontal lobes, temporal lobes, parietal lobes, and occipital lobes. Lobes and their Functions. The cerebral cortex, which is the outer surface of the brain, is associated with higher level processes such as consciousness, thought, emotion, reasoning, language, and memory.
The motor cortex corresponds to the precentral gyrus of the frontal lobe. The precentral gyrus contains the primary motor cortex (Brodmann area 4), which is responsible for integrating signals from different brain regions to modulate motor function. The primary motor cortex is where the corticospinal tract originates. Anterior to the primary motor cortex of the precentral gyrus is the premotor Another fascinating avenue of research involves the Pallium Brain: Exploring the Complex Structure and Functions of the Cerebral Cortex. This outer layer of the brain, which includes all the lobes we've discussed, is a key area of interest for researchers trying to understand higher cognitive functions. Understanding the structure and These functions are processed by an area of your parietal lobe called the somatosensory cortex. Processing hearing information. This function is processed by an area of your temporal lobe called the auditory cortex. Processing taste and flavor. These functions are processed by an area of your frontal lobe called the gustatory cortex.
Brain Lobes: Structure and Functions Explained Biology Diagrams
The cerebral cortex is composed of a complex association of tightly packed neurons covering the outermost portion of the brain. It is the gray matter of the brain. Lying right under the meninges, the cerebral cortex divides into four lobes: frontal, temporal, parietal and occipital lobes, each with a multitude of functions. It is characteristically known for its bulges of brain tissue known as
Cortical areas and their functions. Four lobes are used to designate specific anatomical locations and functions of the sensory and motor cortical areas. These regions deal with different modalities of sensation, often relayed by the spinal cord or directly by the cranial nerves. Moreover, one of these regions can even initiate conscious motor

The insular cortex is a portion of the cerebral cortex folded deep within the lateral sulcus (the fissure separating the temporal lobe from the parietal and frontal lobes). The insular cortex has an important function for sending axons to the amygdala and responding to tones and somatosensory stimulation. [12]
It includes all of the lobes of the cortex except the limbic lobe and consists of six layers of cells or laminae. total of 52 areas which have been shown to have distinct neuronal organization and have also been correlated to various cortical functions.
