A sulcus (plural: sulci) is another name for a groove in the cerebral cortex.įigure 8. The surface of the cerebrum is called the cerebral cortex, and has a wrinkled appearance, consisting of bulges, also known as gyri, and deep furrows, known as sulci (Figure 8).Ī gyrus (plural: gyri) is the name given to the bumps ridges on the cerebral cortex (the outermost layer of the brain). The occipital lobes also contain the primary visual cortex which receives sensory information from the retinas, transmitting this information relating to location, spatial data, motion, and the colours of objects in the field of vision. Some of the functions of the occipital lobes include being able to assess size, depth, and distance, determine colour information, object and facial recognition, and mapping the visual world. The occipital lobes receive sensory information from the retinas of the eyes which is then encoded into different visual data.

The occipital lobes are located at the back of the brain behind the temporal and parietal lobes and below the occipital bone of the skull (Figure 7). The cerebrum is divided into four lobes: frontal, parietal, occipital and temporal. The four lobes of the brain are the frontal, parietal, temporal, and occipital lobes (Figure 3).įigure 3. These left and right functions are the case in the majority of people, especially those who are right-handed.Ĭerebral hemisphere can be subdivided into four lobes, each associated with different functions. The right hemisphere is associated with more visuospatial functions such as visualization, depth perception, and spatial navigation. The left hemisphere is associated with language functions, such as formulating grammar and vocabulary, and containing different language centres (Broca’s and Wernicke’s area). Each of these functions are localized to either the right or left side. Hemispheric lateralization is the idea that each hemisphere is responsible for different functions.

The two sides are connected by the nerve fibers corpus callosum. The cerebrum is divided into left and right hemispheres. With each other and allows for information being processed on one side of the brain to be shared with theįigure 2. The corpus callosum allows the two hemispheres to communicate The two hemispheres are connected by a thick band of neural fibers known as the corpus callosum,Ĭonsisting of about 200 million axons. The left hemisphere controls the right half of the body,Īnd the right hemisphere controls the left half of the body. The cerebrum is divided into two halves: the right and left hemispheres (Fig. The brainstem works by regulating automatic functions such as sleep cycles, breathing, body temperature, digestion, coughing, and sneezing. This area connects the cerebrum and the cerebellum to the spinal cord, acting as a relay station for these areas. Although the cerebellum only account for roughly 10% of the brain’s total weight, this area is thought to contain more neurons (nerve cells) than the rest of the brain combined.īrainstem: is located at the base of the brain. This structure is also important for regulating posture and balance, as well as recently being suggested for being involved in learning and attention. The cerebrum produces higher functioning roles such as thinking, learning, memory, language, emotion, movement, and perception.Ĭerebellum: is located under the cerebrum and is responsible for monitoring and regulating motor behaviors, especially automatic movements. The cerebrum is divided into two hemispheres, the left and right, and contains the lobes of the brain (frontal, temporal, parietal, and occipital lobes). It consists of grey matter (the cerebral cortex) and white matter at the centre. The brain has three main parts: the cerebrum, cerebellum and brainstem.Ĭerebrum: is the largest and most recognisable part of the brain. The brain is composed of the cerebrum, cerebellum, and brainstem (Fig. The PNS is made up of 31 pairs of spinal nerves that branch from the spinal cord, and cranial nerves that branch from the brain. There is also a peripheral nervous system (PNS) which is comprised of The brain is part of the central nervous system (CNS) along with the spinal cord. This information is processed in the brain, allowing us to give meaning to the input it receives. The brain receives information through our senses: sight, touch, taste, smell, and hearing. The brain controls all functions of the body, and interprets information from the outside world, and defines who we are as individuals and how we experience the world. It contains the cerebrum which makes up about 85% of the total It is the centre of all conscious awareness and is divided into different lobes The brain receives information from sensory receptors and sends messages to musclesĪnd glands.
