The human brain.


The human brain.

It’s no secret that humans are social animals. The success of Twitter, Facebook and other forms of social media has recently highlighted the need for human interaction.

Although social interaction is important for human experience, it’s not always easy. In fact, almost every part of the human brain, arguably the most complex thing ever, works and plays with other people.

Recognize social signals

The first step in social interaction is to perceive important social cues. We listen to what people say, say, look at the details of facial expressions, pay attention to how we touch, if someone smells unpleasant, they hate wrinkles. Each of these functions relies on a unique area of the brain.

For example, the fusiform gyrus, located near the base of the brain, specifically involves looking at the face, the right superior temporal sulcus on the side of the brain to help us pay attention to where others are looking. Part of the occipital cortex is devoted to observing other human bodies. Ancient evolutionary pathways connect to the upper hills, which help control basic visual information, and the amygdala regulates strong human emotions.

Our brains are tuned into human voices. The entire neural network is dedicated to more than 90 percent of the language in the left side of the brain.

There is a similar network on the right side of the brain that interprets the rhythm, and people add layers of meaning to the words they say.

Tactile transmission of information to the insula can evoke emotional responses. The sense of smell is closely linked to the limbic system, and the limbic system manages emotions and rules.

We have unique emotional cues for almost every sensation, especially when others are involved.

Filtering information

The next basic step in social interaction is determining whether social signals are really important. Certain brain structures produce initial emotional responses to social stimuli. What if someone’s tone really affected us? What does a person’s appearance really mean? Are we overreacting?

Deep in the brain, the amygdala seems to be particularly involved in choosing which numberless incoming social signals are most important. The amygdala can be thought of as an afferent signal of emotional value. For people with amygdala damage, it is much more difficult to recognize the face of fear, and to feel emotions, they don’t look at others’ eyes.

The insula is also important in allocating the emotional value of different stimuli, such as deciding when to be sick. This may be crucial in society, because the insula is the inappropriateness of the chronic nose picking in public. Lesions in this area of the brain can lead to attention to inappropriate situations. For example, in the disease frontotemporal dementia, island leaf degeneration may become an act of indifference to personal hygiene.

Regions known as the anterior cingulate cortex respond to different situations. The anterior cingulate cortex connects to many other parts of the brain, and is where feelings translate into action. For example, if the insula determines the nausea, the anterior cingulate cortex sends information to the part of the brain that works together, called “nausea.” People who have had a stroke in this area may have extreme indifference, even to unmotivated silence, or even lack of motivation, or even movement or speech.

The orbitofrontal cortex at the base of the brain and the front of the brain indicates when the incoming social signals are valuable.

Studies have shown, for example, that these areas are very active in romantic love. This is especially true in a region known as the nucleus accumbens.

The role of experience

Most of the structures we’ve discussed so far are “hardwired”, meaning that they are relatively ancient paths and structures that are not easily changed. However, the neocortex (” new “means” new “) is more adaptable. This new part of the brain is our experience that allows us to change the way we interact with other people.

The correct pattern of social behavior is in the medial prefrontal cortex. Until the early 1920s, the region was not fully mature, which gave us time to develop our unique personality and to choose how we should respond to different social interactions. The ventral prefrontal cortex may be involved in identifying the consequences of breaking the rules. The field may be less active in antisocial circles.

Protocol parsing

Even if all social information processing is done properly, if we respond in an awkward or inappropriate way, it doesn’t matter much. In our daily lives, it is important that we carefully limit our actions and choose the best behavior. If you don’t do well, the conflict will arise. Marriages break down, business deals collapse and friendships fail.

Human beings have unique complex social interactions, mainly controlled by the prefrontal cortex. This can control and suppress a more immediate response, and even if we feel angry or insulted, we can respond appropriately.

The medial prefrontal cortex tells us what emotions we feel. People with this disease don’t know how they feel. Therefore, it is difficult for them to adjust or control their emotions.

The lateral prefrontal cortex appears to be more involved in regulating the emotional capacity of the medial prefrontal cortex. It also helps us adapt to new situations. For example, even if we are raised in a biased family, this is the area where we can overcome our prejudice.

The original social network.

To some extent, the brain reflects our own society. Both we and our neurons are in the communication network. One neuron can share information directly with hundreds of other people and communicate with billions of people in the body. By coordinating our hands and lips, this electrical chatter in our own brain is a much warmer analogue signal for cellular signals or for face-to-face interactions. Communication between nerve cells becomes communication between people.
