What Is The Gray Matter And White Matter

The Brain’s Frontal Lobes – Part 2

Gray and white matter are two different regions of the central nervous system. In the brain, gray matter refers to the darker, outer portion, while white matter describes the lighter, inner section underneath. In the spinal cord, this order is reversed: The white matter is on the outside, and the gray matter sits within.

Gray matter is primarily composed of neuron somas , and white matter is mostly made of axons wrapped in myelin . The different composition of neuron parts is why the two appear as separate shades on certain scans.

Each region serves a different role. Gray matter is primarily responsible for processing and interpreting information, while white matter transmits that information to other parts of the nervous system.

Development Of The Prefrontal Cortex

The brain develops in a back to front pattern, and the prefrontal cortex is the last portion of the brain to fully develop. This does not mean that children do not have functional prefrontal cortices. Rather, they do not develop the complex decision-making and planning skills adults have until they are older.

During adolescence, the brains network of neurons develops many more synapses. These connections increase communication between parts of the brain and allow the individual to learn complex skills. However, this growth may happen unevenly.

For example, most fifteen-year-olds can assess hypothetical risk as well as adults. However, a teens prefrontal cortex has not grown many connections with the limbic system yet. In other words, the part of the brain that provides self-control cant communicate well with the part of the brain that controls the fight or flight response. Thus, the same fifteen-year-old may act rashly under stress, even if they technically know better.

Experience plays a role in the development of the prefrontal cortex. Teens exposed to a variety of stimuli and challenges may mature more quickly. However, most neurologists agree that the prefrontal cortex is not fully developed until around the age of 25.

Language And Spatial Abilities

There are also functions that are predominantly controlled by the left frontal lobe or the right frontal lobe. Along with the neighboring parietal and temporal lobes, the dominant frontal lobe is involved in language, rational, quantitative, and logical thinking, and analytical reasoning.

The right frontal lobe is involved with creativity, imagination, intuition, curiosity, musical and artistic ability.

The Biggest Part: The Cerebrum

The biggest part of the brain is the cerebrum. The cerebrum is the thinking part of the brain and it controls your voluntary muscles the ones that move when you want them to. So you need your cerebrum to dance or kick a soccer ball.

You need your cerebrum to solve math problems, figure out a video game, and draw a picture. Your memory lives in the cerebrum both short-term memory and long-term memory . The cerebrum also helps you reason, like when you figure out that youd better do your homework now because your mom is taking you to a movie later.

The cerebrum has two halves, with one on either side of the head. Scientists think that the right half helps you think about abstract things like music, colors, and shapes. The left half is said to be more analytical, helping you with math, logic, and speech. Scientists do know for sure that the right half of the cerebrum controls the left side of your body, and the left half controls the right side.

Brain Structure And Function

What Is the Right Frontal Lobe? (with pictures)

The brain has two halves or hemispheres: right and left. The right hemisphere controls the left side of the body, and the left hemisphere controls the right side. In most people, the left hemisphere regulates language and speech, and the right hemisphere controls nonverbal, spatial skills. If the right side of the brain is damaged, movement of the left arm and leg, vision on the left, and/or hearing in the left ear may be affected. Injury to the left side of the brain affects speech and movement on the right side of the body. Each half of the brain is divided into main functional sections, called lobes. There are four lobes in each half of the brain: the Frontal Lobe, Temporal Lobe, Parietal Lobe, and Occipital Lobe. Other important sections of the brain are the Cerebellum and the Brain Stem. Although not usually divided into lobes, the cerebellum and brain stem both have different parts. Each of the brain hemispheres and lobes, cerebellum, and brain stem has specific functions, and they all work together:

Symptoms Of Frontal Lobe Damage

Damage to the frontal lobe can exhibit multiple signs and symptoms that can occur together. This event is called dysexecutive syndrome. It is divided into 3 categories: the cognitive , emotional and behavioral.

  • Movement: Presence of tremors, dystonia, apraxia, gait disorder and clumsiness.
  • Emotional: Difficulty controlling emotions, excitement, anger and depression including difficulty in understanding others opinions
  • Behavioral: Difficulty in utilizing and perseveration of behavior, social inhibition and in some cases compulsive eating.
  • Language : Presence of aphasia and expressive aphasia.

There are some studies where patients experience several symptoms but not all of them. Thus researchers are still arguing about the term dysexecutive.

The Importance Of The Frontal Lobe

The difference between having a frontal lobe like that of healthy, adult human beings and not having one is the difference between being an organism guided primarily by impulses and emotions or one which, although it is primarily motivated by emotional states generated by the limbic system, is able to defer these impulses to follow elaborate plans and choose to achieve goals that are abstract or located at a very distant moment in time.

However, the role of the frontal lobe goes beyond being a set of neurons and glia that allows for long-term thinking. We will explore its potential in the following lines.

Effects Of Frontal Lobe Damage

MRI studies by Levin in 1990 indicated that the frontal lobe is the region thats most likely to experience mild to moderate injury. The left frontal lobe is mainly responsible for controlling movements related to language while the right frontal lobe is responsible for the non-verbal movements.

Based from Kolb and Milner, an individual that suffered from frontal damage could display few spontaneous movements in the face and speak fewer words or vice versa for right frontal lesions.

A common characteristic of a frontal brain injury is difficulty to interpret feedback from the environment. There is also a dramatic change in a persons social behavior.

Structure And Functions Of The Frontal Lobe

What Does the Brain’s Frontal Cortex Do? (Professor Robert Sapolsky Explains)

The frontal lobe is located in the most anterior part of the brain, specifically the entire cerebral cortex starting from the central sulcus. It is considered a very important lobe because it fulfills central functions in information processing, especially relevant are those that have an executive nature.

However, the frontal lobe is divided into multiple regions that provide it with a great variety of functions.

When it comes to grouping the different functional structures of the lobe, we can speak of two large territories. One of them would be the territory corresponding to the motor cortex, which would fulfill motor functions.

The other territory would be the prefrontal cortex, the one in charge of executive processes, decision-making and different aspects related to the regulation of emotions.

Brain Lobes And Their Functions

The brain is divided into four sections, known as lobes . The frontal lobe, occipital lobe, parietal lobe, and temporal lobe have different locations and functions that support the responses and actions of the human body. Let’s start by identifying where each lobe is positioned in the brain.

Position of the Lobes

The frontal lobe is the emotional control center of the brain responsible for forming our personality and influencing out decisions. The frontal lobe is located at the front of the central sulcus where it receives information signals from other lobes of the brain.

The parietal lobe processes sensory information for cognitive purposes and helps coordinate spatial relations so we can make sense of the world around us. The parietal lobe resides in the middle section of the brain behind the central sulcus, above the occipital lobe.

The temporal lobe is located on the bottom of the brain below the lateral fissure. This lobe is also the location of the primary auditory cortex, which is important for interpreting the sounds and the language we hear.

The occipital lobe is located at the back portion of the brain behind the parietal and temporal lobes. The occipital lobe is primarily responsible for processing auditory information.

Functions of the Lobes

The frontal lobe has many functions most of which center on regulating social behavior. Here are some of the important functions of the frontal lobe:

  • Visual-spatial processing
  • Movement and color recognition

How Does The Brain Work

The brain sends and receives chemical and electrical signals throughout the body. Different signals control different processes, and your brain interprets each. Some make you feel tired, for example, while others make you feel pain.

Some messages are kept within the brain, while others are relayed through the spine and across the bodys vast network of nerves to distant extremities. To do this, the central nervous system relies on billions of neurons .

Risks Of Damage To The Frontal Lobe

The Brain

Seizures. Some seizure disorders are caused by damage to â or a malformation in â the brain’s frontal lobe. Seizures impact your motor abilities and speech. Your doctor will assess your seizures and determine which region of your frontal lobe may be impacted.

Personality and social skills. Because the frontal lobe is large and in the front of your skull, it is susceptible to damage. Any damage may contribute to changes in your social behavior. Damage may impact your spatial orientation and coordination of your facial muscles.

What Is Located In Left Frontal Lobe

The frontal lobe of the brain is divided into two, the right and left hemispheres. The right frontal lobe helps us interpret and process spacial and visual information. The left frontal lobe is responsible for language and speech.

Part of the left frontal lobe that deals with expressing your thoughts through words is called the Brocas area.

Frontal Lobes And Voluntary Controlled Behavior

Among the important functions of the frontal lobes are voluntary movement and control of behavior . Below, I detail the role of the frontal lobes in motor behavior with reference to four key regions with distinct yet interrelated functions . While the role of premotor cortex in the mirror neuron network seems to be the most sociologically relevant function on the surface, together these regions enable humans to perform complex motor tasks including speaking and thus it is crucial to have a basic understanding of all of them.

What Is The Frontal Lobe

As the name suggests, the frontal lobe is located in the front of your brain, near your forehead. This lobe controls voluntary muscle movements and higher cognitive functions.

The frontal lobe works together with other lobes to control overall functions. As a result, its inaccurate to attribute any particular action to a single brain region.

Frontal lobe damage strikes at the very heart of what makes a person unique. It can affect your talents, memories, and even your personality.

How The Eyes Communicate With The Brain

When we decide to look at something, a brainstem structure called the pons is called into action. It controls eye movement, constantly telling our eye muscles to move toward the correct stimulus of light .

When light enters the eye through the pupil, it strikes in the retina called rods and cones. Rod cells are responsible forperipheral vision and night vision, while cone cells react to brighter light, color and fine details.

When light hits its corresponding rod or cone, the cell activates, firing a nerve impulse through the optic nerve the middle man between the eye and the brain.

This impulse travels across countless nerve endings and eventually ends up with our pal the occipital lobe, where its processed and perceived as a visible image. This is eyesight.

Since an image isnt much help without meaning, the occipital lobe sends this visual information to the hippocampus in the temporal lobe. Here its stored as a memory.

All of this happens within the tiniest fraction of a second, allowing us to perceive the world in essentially real time.

The human brain is an incredibly complex web of neurons and synapses. And the more we understand about its mind-boggling ability to process and make sense of random collections of light, the more we can appreciate the equally complex world around us.

Ventricles And Cerebrospinal Fluid

Deep in the brain are four open areas with passageways between them. They also open into the central spinal canal and the area beneath arachnoid layer of the meninges.

The ventricles manufacture cerebrospinal fluid, or CSF, a watery fluid that circulates in and around the ventricles and the spinal cord, and between the meninges. CSF surrounds and cushions the spinal cord and brain, washes out waste and impurities, and delivers nutrients.
