What is the brain’s role in the learning process? Does the learning process include the three major areas of the brain: hindbrain, midbrain, and forebrain? The brain is one of the most captivating organs in the body. It plays a huge role in how we learn and is made up of many components. Neurons are brain cells and people are born with over a billion of them. Neurons discharge signals to transmit information throughout the brain; these signals are called synapses. Neurons produce dendrites and they get larger as we learn. However, a dendrite gets bigger only if there is existing knowledge on something already learned. The brain consists of three areas and four lobes. The three parts are known as the hindbrain, midbrain, and forebrain. The four lobes of the brain are the frontal, parietal, occipital, and the temporal.

“Alzheimer's disease is a progressive, degenerative disorder that attacks the brain's nerve cells, or neurons, resulting in loss of memory, thinking and language skills, and behavioral changes. These neurons, which produce the brain chemical, or neurotransmitter, acetylcholine, break connections with other nerve cells and ultimately die. For example, short-term memory fails when Alzheimer's disease first destroys nerve cells in the hippocampus” (Alzheimer’s Association Foundation.) The destruction of the hippocampus is very serious because the hippocampus is a structure in the brain’s limbic system that plays an important part role in memory (Ettinger 91.) Its is responsible for forming organizing and storing memories.It connects the memories to structures and senses like smell and sound. “The hippocampus is a horseshoe shaped paired structure, with one hippocampus located in the left brain hemisphere and the other in the right hemisphere. The hippocampus acts as a

Since it is close structurally to the hippocampus, the amygdala is involved in controlling memory consolidation, especially emotional memories; when a memory is emotionally charged, it has a better retention rate than one that is not. The hippocampus is generally seen as having an essential role in the creation of new memories about past experiences; it's even responsible for memories that can be verbalized also known as declarative memory. Damage to it result in difficulties in forming new memories and being able to access new memories formed before the

The part of the brain that is in charge of memory is called the hippocampus, which is part of the cerebral cortex. The cerebral cortex is in charge of thinking, problem solving, and many different kinds of language skills. People that have a problem with their hippocampus can have trouble remembering new details they have taken in. There are also many different parts of the hippocampus that apply directly to the memory. These parts include short-term memory, long-term memory, sensory memory, and the constructive processes. Short-term memory is the information that stays in your brain only when you are thinking about it, about 20 to 30 seconds. After this, it is most likely forgotten. Long-term memory is when your hippocampus keeps track of facts you learn, ideas you have, and experiences. Even when people stop thinking about these things, the memory can last a lifetime. Another part of the hippocampus, sensory memory, remembers information only for one or two seconds. The brain creates a mental image that disappears when you stop directly thinking about a particular thing. The last part of the hippocampus is the constructive processes. Constructive processes are memories that your brain makes up in order to make sense of a detail in which you only remember some of the details. The few details that the brain remembers are combined with other small details that your brain adds in order for it to

Some researchers hypothesize that the hippocampus is involved in some types of memory processes but not others. This particular study measured brain activity using fMRI during two types of memory tasks: remember (episodic memory) and know (familiarity). A memory was considered “episodic” if the person could recall the moment it was learned and “familiar” if they felt they recognized the word but could not retrieve the specidic moment it was learned. The a priori (pre-selected) region of interest( ROI) in the hippocampus

What is the hippocampus? The hippocampus is the formation of memories and a part of the cerebrum.Some people say if you damage the hippocampus you develop a disease called Antevograde amnesia which is the unibaily to form new memories.It also said there are regions that regulates the emotions.

Hippocampus is a small, curved region, which exists in both hemispheres of the brain and plays a vital role in emotions, learning and acquisition of new information. It also contributes majorly to long term memory, which is permanent information stored in the brain. Although long term memory is the last information that can be forgotten, its impairment has become very common nowadays. The dysfunction is exemplified by many neurological disorders such as amnesia. There are two types of amnesia, anterograde and retrograde. Anterograde amnesia is inability in forming new information, while retrograde refers to the loss of the past memory. As suggested by Cipolotti and Bird (2006), hippocampus’s lesions are

involved in memory storage. The hippocampus is a place in the brain that is used to

Doctors and scientists dispute the exact role of the hippocampus, but agree that it has an essential role in the formation of new memories about personally experienced events. Some researchers prefer to consider the hippocampus as part of a larger medial temporal lobe memory system responsible for declarative memory. When a long-term, declarative memory is made, certain neuronal connections in the temporal lobe are strengthened, and others are weakened. These changes are fairly permanent, however some may take weeks or months before they are complete

The most important part of the brain involved in memory is the cerebral cortex. It is located on the outermost layer of the brain and is responsible for thinking and processing information from the five senses. It is made up of tightly packed neurons and is the wrinkly-like form that surrounds the brain. The cortex is divided into four different lobes-the frontal, parietal, temporal and occipital, which are all for different types of sensory information. As the name indicates, the frontal lobe is located on the front of the brain. The frontal lobe is the part of the brain that controls important everyday cognitive skills such as emotion, problem solving, memory, language, judgement, and sexual behaviour. It has often been described as the “control panel of our personality and our ability to communicate.” The parietal love is located on the upper back part of the cortex and is involved in the sensory information that should do with touch taste and temperature. This lobe can carry information within seconds, with the information being integrated and processed. The temporal lobe is positioned on the bottom part of the cortex, right behind the temples on your face. Its function is to process auditory information from the ears. “It is also key to being able to comprehend or understand speech.” One of the most

The hippocampus assumes an essential part in our recollections. It appends recollections to the feelings and faculties that run with them. For example, it will take a memory of being cheerful and quiet while in a field and connection it with the possess a scent reminiscent of the blossoms. It will relate both the sentiment being upbeat and the feeling of smell to the memory of being in a field.

The brain is dividing into several sections, including the cerebellum, the frontal lobe, and the temporal lobe, among others. The temporal lobe exists in two parts, one on each side of the brain close to the ears. It is largely responsible for the memory system (2). On the medial surface of the temporal lobe there are three important structure that are essential for human functioning. These structures are named, in order from rostral to caudal, the olfactory cortex, the amygdala, and the hippocampus. Together these three structures are referred to as the "limbic system" (1). Their functions became understood after studying how the brain functions upon loss of each structure. For example, in 1953, a patient suffering from epilepsy underwent surgery which removed most of his medial temporal lobe (1). After the surgery, the patient was able to remember who he was and was able to carry out coherent, intelligent conversations. However, if the person with whom he was talking left the room, he would have no

Without the hippocampus, the information from the short-term memory (STM) cannot be stored in long term memory (LTM). The hippocampus is a very important part of the human brain to store our memories. If we lost it, we will lose all our conscious memories. From Henry’s case, it also discovered that there are multiple memory storage areas located at different parts of the brain while the hippocampus is important to consolidate short-term memory to long-term memory. The removal of hippocampus caused Henry to suffer until he died as he lost the ability to make new conscious
