The human brain is a very complicated and fascinating organ. It is one of the most important organs, being responsible for controlling every living action our bodies make, be they conscious or unconscious. The central sulcus is an interesting and important part of the brain. The central sulcus is the central groove found in the cerebral cortex of the brain, it is also known as the Rolando Fissure. The central sulcus connects the frontal and parietal lobes....

The human brain (and the brains of most higher organisms) is a wonderful, complex organ. The various regions work together to allow the organism to process information, make decisions, and instruct the various body parts to react accordingly. However, none of this functionality is possible without the various “pathways” distributing information between the various regions. A prominent and essential pathway is the paired cerebral peduncles. The cerebral peduncles are essential parts of the midbrain....

It would be great if everyone had photogenic memory and could store necessary information long-term; however, there is a process that human beings go through to interpret and remember things efficiently. It is called elaborative rehearsal. Let’s look at what that means. Elaborative rehearsal is a control process that human beings use to embellish specific information that the mind interprets for long-term memory storage in the brain. It links new information to old materials through memory encoding strategies to make remembering easier for extended periods....

There are many illnesses or medical reasons why you have sudden onset headaches or early onset memory loss, but one unknown area of the brain may be a cause. The section of the brain that may be responsible is known as the fornix.The fornix in the brain is a C-shaped area of myelinated fibers of the telencephalon. They are situated in the mesial aspect of the cerebral hemispheres. It projects to the hypothalamus from the hippocampal formation and is part of the limbic system....

The term hypophyseal portal system sounds complicated and, at a glance, seems difficult to understand. If you’re into some form of anatomy, physiology, and psychology, you have probably come across the term and tried to figure out what the hypophyseal portal system is. The hypothalamic-hypophyseal portal system links the hypothalamus and anterior pituitary gland through a system of veins that start and end in capillaries to quickly transport and exchange hormones....

Ionotropic receptors are one of two primary neurotransmitter receptors. Ionotropic receptors are mainly located along the cell body, but they can be found anywhere along a neuron if there is a synapse. Receptors can be located in many different parts of the body and act as excitatory or inhibitor receptors for a specific neurotransmitter, but are ionotropic receptors the same? Ionotropic receptors have a vital role to play in the body....

The subarachnoid plays a crucial role in the brain and the cerebrospinal fluid of the brain. So, what is the subarachnoid space, and why is it so important in the brain? The area between the pia mater and the arachnoid membrane is known as the subarachnoid space. It is home to branches of the brain’s arteries and veins as well as delicate connective tissue trabeculae, intercommunicating channels, and cerebrospinal fluid (CSF)....

The brain is unique in appearance with indentations and depressions. Just 3 pounds in weight, the adult brain is 60 percent fat; the rest’s water, protein, carbohydrates, and salts. We know about the brain’s gray and white matter but much less about the folds. So what is the brain’s surface called a sulcus? Sulcus is the patterned grooves or furrows on the brain’s cerebral cortex that increase the brain’s size and separate the lobes and irregular-shaped ridges of the gyri....

Health Psychology is a sub division of psychology which focuses on the affects of illnesses and other influences on health factors such as biological, psychological as well as behavioral.Health psychologists comprehend how individuals behave in terms of actions, reactions, cope and recover from any kind of ailments. To contribute to health care industry greatly you must consider the top statesto study health psychology.North CarolinaThe state of North Carolina is located in south-eastern region of the United States and ranks 10thfor being highly populated....

The ventral tegmentum is composed of anumber of neuronsthat are located in themidbrain. They are found on the floor of the brain close to the midline brain. The ventral tegmentum plays a significant role in a number of functions, including those associated withreward. With the ventral tegmentum being involved in a large number of functions and therefore being of significant importance, this may seem rather intimidating. There is no need to be, and we will provide you with all you need to know about the ventral tegmentum, from where it is located, to what it does, as well as what will happen should this area become damaged or diseased....

Afferent nerves are responsible for our brain to experience what is on the outside of our bodies and interpret it. For example, the world is full of beauty and awe-inspiring sights and smells; to fully appreciate them, we need afferent nerves to relay these images, scents, and tastes. Afferent nerves are axon projections carrying peripheral organ stimulus to the central nervous system. These message-relaying neurons bring external information such as touch, smell, hearing, and sight from various body parts to the CNS for analysis and processing....

The lateral sulcus is a deep groove on the inferior flank ofeach cerebral hemisphereof the brain. The depth of this cerebral cortex cleft is vast and partitions the parietal and frontal lobes entirely from and temporal lobe. This sulcus is referred to as theSylvian fissure, named after 17th-century neuroanatomist Franciscus Sylvius. The lateral sulcus is a significant cerebral feature. It’s on each side of the brain’s hemispheres. This immensely deep groove has characteristic bulges that fold over and obscure it- called opercula....

The primary function of the Nodes of Ranvier is to speed up the transmission of neural impulses in nerves. Within this primary function, the sub-functions of the Nodes of Ranvier include the maintenance and correction of the impulse action potential which maintains efficient saltatory conduction. Not only do the Nodes of Ranvier correct and repair the waves transmitted through the neural fibers, they potentially build up the standard action potential of the wave’s trough and its subsequent standard electrical current....
