Which Part Of The Brain Controls Memory
There are three main areas of the brain: the cerebrum, the cerebellum, and the brain stem. As well as hemispheres and lobes. They play key roles in encoding, storing, and retrieving memories.
Consisting of three main areas: cerebrum, cerebellum, and the brain stem. These parts of the human brain serve in the creation of memories, storing memories, and the retrieval of memories. Working in unison the brain allows for a person to control their memories.
âThe brain is far more intricate than a few bits and pieces stitched together. After all, this is the organ that built the pyramids, painted the Sistine Chapel, wrote Shakespearean sonnets, and landed on the moon.
There are 86 million neurons in the brain, forming a dense network of pathways. While weâre nowhere close to a comprehensive understanding of this three-pound organ, we can localize certain functions and aspects to specific regions, including memory.
Ii Mirror Neurons How Empathy Affects The Brain
A team of researchers at the University of Colorado, USA, in a study published in Neuron in June 2017, reveals that two types of emotional empathy, compassion, and anxiety, activate different areas of the brain.
The team examined the brains of 66 volunteers while listening to real stories of human tragedies, with different outcomes.
The volunteers also had to evaluate how each story made them feel separate, without any scanner. The first great discovery was that there is no region of the brain in which empathy develops, but a network that unites different areas.
The brain is not a modular system where there is an area in charge of empathy. Its a distributed process. The same regions involved in the evaluation of food or money appear to be involved in the study when assessing the well-being of others.
But not all stories linked the same regions and, in fact, generated two types of schema, between those that brought together solidarity and compassion with those that caused empathic anguish. In the first case, areas of the brain such as the ventromedial prefrontal cortex or the orbito-frontal medial cortex have been activated, in relation to the processes with which the brain gives value to something.
The Amygdala And The Affective System
Within the limbic system sits the amygdala, which has been shown to control our instantaneous emotional responses. The amygdala is, therefore, likely to represent the brain region in charge of the affective system, which is responsible for many of our judgments, such as discerning between good and bad, safe and threatening, and friend and foe.
One further, important responsibility of the amygdale , is to help us identify facial expressions. We use facial expression information to make the value judgment of friend or foe, and this value judgment is also important to consumer and user behavior, where faces are often used to engender positive feelings. As the amygdala is in charge of our judgmental system, it helps us determine which brands, products and sites we can trust and which ones are threatening or of no use to us.

Which Part Of The Brain Deals With Emotions
Now, you know what parts of the brain deal with thinking and memory. Lets have a quick look at the part that is responsible for emotions.
All positive and negative emotions, and spontaneous feelings think excitement and sadness, are being processed in the limbic system.
The limbic system control your emotions and interacts with other parts of the brain.
In the same time, another part of the brain called amygdala handles emotional reactions such as love, hate, and sexual desire.
With centuries of research, the human brain remains the biggest mystery in the world. It is the most complex part of the body that controls movement, sight, and thinking.
A Psychological Constructionist Account Of The Brain Basis Of Emotion
A psychological constructionist account of emotion assumes that emotions are psychological events that emerge out of more basic psychological operations that are not specific to emotion. In this view, mental categories such as anger, sadness, and fear are not respected by the brain . A psychological constructionist approach to emotion is as old as the locationist approach, at least in its nascent form . Our contemporary psychological constructionist approach shares much in common with cognitive neuroscience approaches arguing that basic psychological operations are common across diverse task domains . As in the neural context hypothesis, it assumes that the psychological function of individual brain regions is determined, in part, by the network of brain regions it is firing with . It is also consistent with recent evidence that large-scale networks intrinsic to the brain interact to produce psychological events . In philosophy of mind, it is consistent with both a token identity and a supervenience approach to mindbrain correspondence and the mental mechanisms approach . We discuss the psychological constructionist view in somewhat more detail because it is unfamiliar to many readers.

How Does The Limbic System Control Emotions
The hypothalamus, amygdala, thalamus, and hippocampus are the four main components of the limbic system:
- The hypothalamus controls the endocrine system. The effects on your body are a faster heartbeat, dilated pupils, and quicker breathing.
- The amygdala is related to feelings of fear, anxiety, and anger. In collaboration with the hypothalamus, the amygdala is responsible for the fight-or-flight response.
- The thalamus is responsible for directing sense into the corresponding areas in the cortex. In the context of emotions, senses influence them immensely. This is why certain nostalgic songs may trigger an emotional response.
- The hippocampus processes sensory input and helps the limbic system produce an appropriate reaction. It converts short term to long term memory and ties emotions into memories.
The brain is a complex piece of organic machinery. And even when it feels as if our emotions are out of control, there are actually many predictable, structured processes responsible for our emotional responses.
What Is The Gray Matter And White Matter
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.

What Part Of The Brain Controls Mood And Emotional Behavior
Your emotional response and the general mood are generated in the amygdala. But its the prefrontal cortex thats responsible for planning future action, aka, the way you behave based on those emotions.
So if you thought about robbing a bank, your prefrontal cortex would help you process the idea and connect it to an appropriate emotional response.
If the amygdala is damaged, you lose control of base impulses. In fact, you may even begin to act in an inappropriate way. Disinhibited behavior, hypersexuality, and risk-taking are behavioral consequences of a damaged amygdala.
The left hemisphere of the brain processes while the right hemisphere identifies. For example, if you felt as if you were falling in love, your right hemisphere would identify the feeling, but your left hemisphere would help you decide on how to act.
Do Emotions Come From The Heart Or Brain
It is true that the brain and the heart are related, since the heart beats at a different rate depending on the emotions that our body feels, but it is the brain that is in control.
In this article we answered the question What part of the brain controls mood? We explained how the brain controls emotions, what is the structure that is responsible for these processes and regulates mood.

Your Brain’s Hemispheres Keep Your Emotions In Check
If you were to crack open your skull and take a look at the gray matter contained within it, you’d see that the brain appears to be divided into two equal-sized halves. These are your brain’s hemispheres and, while they work together to keep you functioning, they each take responsibility for processing different types of information. The left side of your brain thinks in concrete ways, such as the literal meaning of words and mathematical calculations, while the right side thinks in more abstract ways, such as symbolism and gestures .
Because the two sides of your brain process information differently, they work together to keep your emotions in check. Here’s an easy way to explain it: The right hemisphere identifies, and the left hemisphere interprets. The right brain identifies negative emotions, like fear, anger or danger. It then alerts the left brain, which decides what to do by interpreting the situation and making a logical decision about how to act in response.
It’s a great system, unless something happens and one side of the brain can’t do its job. Without the left brain, the right brain would be overcome with negative emotions and not know how to respond to them. And without the right brain, the left brain would not be as good at identifying negative emotions .
What Parts Of The Human Brain Correspond To Emotion Or Love
Emotions, like fear and love, are carried out by the limbic system, which is located in the temporal lobe. While the limbic system is made up of multiple parts of the brain, the center of emotional processing is the amygdala, which receives input from other brain functions, like memory and attention.

Research Focus: Identifying The Unique Functions Of The Left And Right Hemispheres Using Split
We have seen that the left hemisphere of the brain primarily senses and controls the motor movements on the right side of the body, and vice versa. This fact provides an interesting way to study brain lateralization the idea that the left and the right hemispheres of the brain are specialized to perform different functions. Gazzaniga, Bogen, and Sperry studied a patient, known as W. J., who had undergone an operation to relieve severe seizures. In this surgery, the region that normally connects the two halves of the brain and supports communication between the hemispheres, known as the corpus callosum, is severed. As a result, the patient essentially becomes a person with two separate brains. Because the left and right hemispheres are separated, each hemisphere develops a mind of its own, with its own sensations, concepts, and motivations .
Although Gazzanigas research demonstrated that the brain is in fact lateralized, such that the two hemispheres specialize in different activities, this does not mean that when people behave in a certain way or perform a certain activity they are only using one hemisphere of their brains at a time. That would be drastically oversimplifying the concept of brain differences. We normally use both hemispheres at the same time, and the difference between the abilities of the two hemispheres is not absolute .
Your Lizard Brain Or Limbic System
The limbic system is responsible for the six fs fighting, fleeing, feeding, fear, freezing-up and fornicating, which are incidentally the favourite hobbies held by lizards.
You might notice as well that the six fs are the best basics for species to explore, expand and reproduce leading them to fight for mates and food and flee for survival. This ancient part of the human brain was, and is, extremely valuable to our survival, yet hasnt reached a level where it can differentiate between an approaching tiger or a high school maths test both of these have the same kinds of responses and chemical reactions.
Its not just a chunk of your brain, however the limbic system is made up of the hypothalamus, amygdala, hippocampus and limbic cortex.
Even this isnt the whole story – the research rolls on and discoveries are constantly rewriting everything we think we know. At this time, heres what we think we know about where the emotions are held:

Its All In The Brain Waves
This mood-related circuit was identified by so-called beta waves in the hippocampus and amygdala, coordinated oscillations between 13 and 30 cycles per second, two deep brain regions that have long been connected to memory and negative emotions, respectively.
Sohal says the study team was initially shocked by the clarity of the discovery. We were very surprised to identify a single signal that almost completely explained episodes of depressed mood in such a large group of people, says Sohal. Finding such a powerfully informative biomarker was more than we expected at this stage of the draft
Fortunately, in eight other study participants, all with relatively low pre-existing pre-existing anxiety, this clear correlation between mood-linked beta waves in the amygdala and the hippocampus was completely absent, indicating additional issues about how the brains of women who are prone to anxiety which differ from others in how they manage emotional situations.
*** Mirror Neurons And Learning
Neuroscientists assume that these neurons play an important role in cognitive abilities related to social life, such as empathy the ability to put oneself in someone elses shoes and imitation. fundamental in learning processes -. As a result, some scientists believe that mirror neuron is one of the most important discoveries of neuroscience in the last decade.
Mirror neurons are essential for us to imitate others, a key element of learning. In different disciplines such as sports or language learning, imitation is essential.
From birth, this group of neurons is active and allows us to learn to eat, dress, to talk Mirror neurons also play a very important role in the planning of our actions and in the understanding of the intentions that exist after the acts of others. Human beings are born with mechanisms that allow us to imitate the actions we perceive. Very young, with only a few days of life, we are able to represent facial expressions that facilitate our socialization and in a few weeks, we can already manifest basic emotions such as joy or anger.

The Effects Of Stress On The Brain:
Stressful events are a non-negotiable part of life.
In fact, the body is wired to withstand and even thrive in the midst of short-term stress.
Unfortunately though, in todays fast-paced world and daily life, most of us are experiencing ever-increasing stress levels and ever-rising cortisol levels.
The negative effects of chronic stress have been well documented.
Its becoming widely accepted now that stress causes health problems such as high blood pressure, heart disease, and even immune system dysfunction.
Stress affects mental health too.
Without proper stress management, it can turn into anxiety, panic disorder, or even post-traumatic stress disorder .
This is because over time stress changes brain function.
Chronic stress really wreaks havoc on our minds.
Stress can literally kill brain cells.
A single stressful situation has the power to kill neurons in the brains hippocampus region , as one animal study showed.
Chronic stress shrinks the brain, which leads to emotional and mental impairment.
Specifically, stress shrinks the prefrontal cortex, which is associated with decision making, complex thinking, working memory, moderating social behavior, and attention control.
Whats worse, a chronically stressed-out brain becomes wired and predisposed to being in constant stress mode, thus creating a vicious cycle.
Chronic stress not only shrinks the part of our brain associated with higher thinking, but it has also been shown to increase the size of the amygdala.
Your Brain Perceives And Acts Upon Emotional Stimuli
Even though we think of emotions as internal states, psychologists define emotions as a combination of cognitions, feelings and actions . This means what we think of as “emotions” includes not only how we feel, but also how we process and respond to those feelings.
To understand this, it’s helpful to consider the purpose of emotions. In 1872, Charles Darwin first published “The Expression of the Emotions in Man and Animals,” which established that emotions serve an important evolutionary purpose. In order for a species to continue, it needs to survive and pass on its genetic information. Emotions like fear serve to protect you from danger so you can survive to pass on your genes. The “fight-or-flight” response that primes your body to defend itself or run away from danger is also an emotional reaction. Emotions like love and lust give you the desire to reproduce.
For these reasons, the brain takes on the function of evaluating a stimulus — such as a dog that’s about to attack or a beautiful woman batting her eyelashes — and crafting an emotional response to it. The brain thinks in terms of how it can best respond to a situation in order to survive and reproduce, and it uses emotions as the catalyst to convince the rest of your body to act accordingly.

Which Part Of The Brain Is Responsible For Thinking And Memory
The majority of thinking-related processes happen in the frontal lobe. These include decision-making, problem-solving, and planning.
The frontal lobe also helps the development of cognition, language processing, and intelligence.
The temporal lobe controls other processes related to language understanding, perception, and recognition. It is also in charge of learning and memory.
Iii Our Cerebral Response To The Good News Of Others Depends On Empathy
According to a study by researchers at the University College of London , published in the October 2015 Journal of Neuroscience, the ability of the brain to respond to the good things experienced by others is determined by the ability of empathy.
Research assigns to a specific part of the brain, the anterior cingulate cortex , as the area particularly attentive to the good news that affects others.
His response varies greatly depending on the level of empathy. In people who are considered very empathetic, the anterior cingulate cortex reacts only to the good things that happen to others, while in less empathic subjects, the ACC also reacts to bad news that is specific to it.
