Protecting your cognitive skills is one of the most important things you can do to help ensure you’re able to function at your best as the years go by. Here are just a few ways you can keep yourself sharp:
How does cognitive decline?
Cognitive function can be disrupted in several different ways. One of the most common is through the aging process. As you get older, nerve cells in your brain called neurons die, and your brain doesn’t do a good job of replacing them. 5 But age isn’t the only reason that cognitive skills can decline. Brain injuries, for example, can damage cognitive function and even result in a change in personality. 6
How does stress affect the brain?
These changes, in turn, can lead to a decline in cognitive function. If your brain produces too much cortisol – known as the “stress hormone” – it may result in a sustained “fight-or-flight” state. This damages the connection between the rest of your brain and the area known as the prefrontal cortex, leading to a decreased ability to learn and memorize. 13

This is the same “intelligence” of the intelligence quotient, better known as IQ. High-quality IQ tests measure the same thing as what health psychologists might call general cognitive function.
Is memory a cognitive function?
The individual cognitive functions themselves are not perfectly distinct, however. For instance, memory can be subdivided into episodic memory, which assesses your ability to remember details like items in a list or events from a story, and working memory, which is your ability to simultaneously keep information in mind, like when you try to remember a telephone number. Though all cognitive abilities tend to be correlated, that is, if you are good at one thing you tend to be good at all the others, these memory abilities tend to be more strongly correlated to each other than to other cognitive abilities, e.g., speed.

Attention is a cognitive function that helps people focus on one task at a time. It is divided into four major types: sustained attention, selective attention, alternating attention, and divided attention.
Cognitive Function of Language
Language development is another part of cognitive function. It is the ability to process and produce sounds, words, and sentences that are used in human communication. Language development can be seen as an ongoing process that starts at birth and continues throughout one's life as one learns how to communicate with others.
What are the cognitive functions of the brain?
Brain cognitive functions are the mentalprocesses that allow us to receive, select, store, transform, develop, and recover informationthat we've received from external stimuli. This process allows us to understand and torelate to the world more e ectively. Cognitive functions are brain-based skills we needto carry out any task from the simplest to the most complex. They are related with themechanisms of how we learn, remember, problem-solve, and pay attention, etc. To be morespeci c, in this paper, we will talk about the perception, attention and memory functionsof the human brain. Several other brain cognitive functions, e.g., arousal, decision making,natural language, motor coordination, planning, problem solving and thinking, will beadded to this paper in the later versions, respectively. Many of the materials used in thispaper are from wikipedia and several other neuroscience introductory articles, which willbe properly cited in this paper. This is the last of the three tutorial articles about thebrain. The readers are suggested to read this paper after the previous two tutorial articleson brain structure and functions [17] as well as the brain basic neural units [16].
What do we think of as memory?
What we usually think of as memory" in day-to-day usage is actually long-term memory,but there are also important short-term and sensory memory processes, which must beworked through before a long-term memory can be established. The di erent types ofmemory each have their own particular mode of operation, but they all cooperate in theprocess of memorization, and can be seen as three necessary steps in forming a lastingmemory. As illustrated in Figure 1, we provide a complete diagram of di erent types ofhuman memory as well as their hierarchical relationships.
What is short term memory?
According to [11], short-term memory acts as a kind of scratch-pad" for temporary recallof the information which is being processed at any point in time, and has been referred toas the brain's Post-it note". It can be thought of as the ability to remember and processinformation at the same time. It holds a small amount of information (typically around 7items or even less) in mind in an active, readily-available state for a short period of time(typically from 10 to 15 seconds, or sometimes up to a minute).
What is attention in neuroscience?
Attention is best described as the sustained focus of cognitive resources on informationwhile ltering or ignoring extraneous information. Attention is a very basic function thatoften is a precursor to all other neurological/cognitive functions. As is frequently the case,clinical models of attention di er from investigation models. One of the most used modelsfor the evaluation of attention in patients with very di erent neurologic pathologies is themodel of Sohlberg and Mateer. This hierarchic model is based in the recovering of attentionprocesses of brain damage patients after coma. Five di erent kinds of activities of growingdiculty are described in the model; connecting with the activities those patients could doas their recovering process advanced.
What is the process of perception?
According to [9], the process of perception begins with an object in the real world, termedthe distal stimulus or distal object. By means of light, sound or another physical process,the object stimulates the body's sensory organs. These sensory organs transform the inputenergy into neural activity-a process called transduction. This raw pattern of neural activityis called the proximal stimulus. These neural signals are transmitted to the brain andprocessed. The resulting mental re-creation of the distal stimulus is the percept.An example would be a shoe. The shoe itself is the distal stimulus. When light fromthe shoe enters a person's eye and stimulates the retina, that stimulation is the proximalstimulus. The image of the shoe reconstructed by the brain of the person is the percept.Another example would be a telephone ringing. The ringing of the telephone is the distalstimulus. The sound stimulating a person's auditory receptors is the proximal stimulus, andthe brain's interpretation of this as the ringing of a telephone is the percept. The di erentkinds of sensation such as warmth, sound, and taste are called sensory modalities.Psychologist Jerome Bruner has developed a model of perception. According to him,people go through the following process to form opinions:
What is perception in psychology?
As introduced in [9], perception is the organization, identi cation, and interpretation ofsensory information in order to represent and understand the presented information, or theenvironment. All perception involves signals that go through the nervous system, which inturn result from physical or chemical stimulation of the sensory system. For example, visioninvolves light striking the retina of the eye, smell is mediated by odor molecules, and hearinginvolves pressure waves. Perception is not only the passive receipt of these signals, but it'salso shaped by the recipient's learning, memory, expectation, and attention. Generally,perception can be split into two processes:
What is memory storage?
According to [8], memory storage is the more or less passive process of retaining informationin the brain, whether in the sensory memory, the short-term memory or the more permanentlong-term memory. Each of these di erent stages of human memory function as a sort of lter that helps to protect us from the #R#ood of information that confront us on a dailybasis, avoiding an overload of information and helping to keep us sane. The more theinformation is repeated or used, the more likely it is to be retained in long-term memory(which is why, for example, studying helps people to perform better on tests). This processof consolidation, the stabilizing of a memory trace after its initial acquisition, is treated inmore detail in a separate section.

How many halves are there in the cerebral cortex?
The cerebral cortex is divided into two halves, or hemispheres. It is covered with ridges (gyri) and folds (sulci). The two halves join at a large, deep sulcus (the interhemispheric fissure, AKA the medial longitudinal fissure) that runs from the front of the head to the back.
Which layer of the brain is thick and tough?
The outermost layer, the dura mater, is thick and tough. It includes two layers: The periosteal layer of the dura mater lines the inner dome of the skull (cranium) and the meningeal layer is below that. Spaces between the layers allow for the passage of veins and arteries that supply blood flow to the brain.
