cut with a butter knife. From the outside‚ the brain’s most distinguishing features are its convolutions‚ or folds. These wrinkles are part of the cerebral cortex (Latin for “bark” or “rind”). The cerebral cortex is the orange-peel thick outer covering to maximize surface area (more cells per square inch). In fact‚ if it were laid out‚ the cortex would be about the size of an unfolded single page from a daily newspaper. Yet it is only a grapefruit-sized organ. Its importance can be attributed to

Dementia Dementia The word Dementia describes a set of symptoms that may include memory loss‚ and difficulties with thinking‚ problem solving or language. Dementia is caused when the brain is damaged by diseases such as Alzheimer’s disease or a series of strokes. Dementia is progressive‚ meaning that the symptoms will gradually get worse. Dependent on which part of the brain is affected a person will present differently. Area of the Brain Key Functions that could be affected Frontal Lobe

QUESTIONS FOR MODEL 1. Which lobe of the brain is important for vision? Where is it located? The occipital lobe is important for vision and it’s located in the left cerebral hemisphere. 2. Which part of the brain is important for reasoning? Where is it located? The frontal lobe is important for reasoning and it’s located in the left cerebral hemisphere. 3. Describe three functions of the nervous system. the function of the nervous system is to send signals from one cell to others‚ or from one part of

thalamus transmits motor impulses from Annette’s basal nuclei to her primary motor area. F. Motor signals from Annette’s primary motor area in her cerebral cortex must travel to the cerebellum so that she can pick up her fork. What part of the brain serves as a bridge from the cortex to the cerebellum? The pons serves as a bridge from the cortex to the cerebellum. G. Parkinson’s disease is causing Annette’s muscles to become increasingly rigid or hypertonic. Maintenance of normal muscle tone

matter (GM)‚ increases in the myelination of cortico-cortical connections and changes in the architecture of large-scale cortical networks. It is currently unclear‚ however‚ how the ongoing developmental processes impact upon the folding of the cerebral cortex and how changes in gyrification relate to maturation of GM/WM-volume‚ thickness and surface area. In the current study‚ we acquired high-resolution (3 Tesla) magnetic resonance imaging (MRI) data from 79 healthy subjects (34 males and 45 females)

it controls some of the reflexive actions‚ eye movement‚ and motor functions. The Forebrain is the largest and most developed part of the brain‚ also known as the Cerebrum. The Cerebrum is covered in a 1.5mm to 5 mm layer which is called a cortex. This cortex is also known as

It is on the lower side of both cerebral hemispheres on each side. This lobe has different functions‚ mainly auditory detection‚ keeping memory and emotional perception. The hippocampus happens to be an area of the brain that consolidates

One can see this insight when examining specific areas of the brain such as the temporal and frontal lobes of the brain. The cerebral cortex is “a large‚ deeply wrinkled sheet of neurons‚ or nerve cells‚ on the surface of the brain’s two hemispheres”. These are defined as the right and left hemispheres and make up the largest volume in the brain. The cerebral cortex controls all sensation‚ thought‚ comprehension‚ higher cognition‚ ideas‚ language‚ memory and emotion (Pinel‚ 2011). The hemispheres
