The accident revealed how the brain areas support cognitive functions. There are various brain areas that support cognitive functions. For example‚ the left frontal region helps in personality development. After the accident doctors examined the skull to see the lesion that caused personality change. The lesion was found in the left frontal region. The lesion affected personality development and led to loose of personality. Also‚ during the

Temporal lobe – Learning new information‚ recording and storage of verbal memory (such as names)‚ and visual memory (such as faces). Frontal lobe – Organising and planning actions‚ language‚ logic‚ personality‚ regulating behaviour‚ learning tasks‚ theoretical

These neurodegenerative diseases are known to us as Alzheimer’s‚ fronto-temporal dementia‚ and Lewy bodies are where over time a build up of abnormal protein deposits in the brain cause the gradual change and damage to the neurons which will cause the shrinkage of the brain.

In a way it’s the world’s most powerful computer because it can process tasks at lightning speeds and simultaneously be in control of our reflexes and every other voluntary and involuntary functions. It is the most important and complex organ as well as our core for learning At the point of birth‚ the brain weighs an average of

All three of these vertebrates have two hemispheres and different lobes. Each vertebrate also has a spinal cord that descends from the brain that carries nerve impulses to and from the body along with blood vessels. All vertebrates have spinal and cranial nerves associated with the brain and spinal cord. Also many systems

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‚ midbrain‚ and hindbrain. There are two hemispheres‚ the left and the right. These two hemispheres are connected by a bundle of nerve fibers called

Broca’s area is located in the lower portion of the left frontal lobe. Broca’s area is involved in several functions that include speech reproduction‚ facial neuron control‚ and language processing. Carl Wernicke’s contributes to Wernicke’s area. Wernickie’s are is one of the main areas located in the cerebral cortex that is responsible for language comprehension. Directionally‚ Wernicke’s area is located in the lower portion of the left frontal lobe. Wernicke’s area is involved in several functions that
