Thinking, temperament, habits, perception of events are different for men and women, for people with a dominant right hemisphere of the brain, from those who have a more developed left. Some diseases, deviations, injuries, factors that contribute to the activity of certain parts of the brain are related to human life, whether he feels healthy and happy. How does an increased temporal lobe activity affect a person’s state of mind?
Location
Upper lateral parts of the hemisphere belong to the parietal lobe. Front and side, the parietal lobe is limited to the frontal zone, from the bottom to the temporal, from the occipital part to the imaginary line going from the top of the parieto-occipital zone and reaching the lower edge of the hemisphere. The temporal lobe is located in the lower lateral parts of the brain and is emphasized by a pronounced lateral groove.
The front part represents a certain temporal pole. The lateral surface of the temporal lobe displays the upper and lower lobes. Brains are located along the furrows. The superior temporal gyrus is located in the area between the lateral groove above and the superior temporal below.
On the back layer of this site, located in the hidden part of the lateral groove, there are two or three convolutions belonging to the temporal lobe. The lower and upper temporal gyrus are separated by the middle. In the lower lateral margin (temporal lobe of the brain, the lower temporal gyrus is localized, which is limited to the same groove at the top. The posterior part of this gyrus continues in the occipital region.
Functions
The functions of the temporal lobe are associated with visual, auditory, taste perception, smell, analysis and speech synthesis. Its main functional center is located in the upper lateral part of the temporal lobe. Here the audio center, the Gnostic, speech center is localized.
The temporal lobes are involved in complex mental processes. One of their functions is the processing of visual information. In the temporal lobe there are several visual centers, convolutions, one of which is responsible for facial recognition. Through the indicated temporal lobe passes the so-called Mayer loop, the damage of which can cost the loss of the upper part of the vision.
The functions of the brain are used depending on the dominant hemisphere.
The temporal lobe of the dominant hemisphere of the brain is responsible for:
- word recognition;
- operates with long and medium duration memory;
- responsible for the assimilation of information when listening;
- analysis of auditory information and partially visual images (while perception combines the visible and audible into a single whole);
- has a complex-composite memory that combines the perception of touch, hearing and vision, while inside the person there is a synthesis of all signals and their correlation with the object;
- responsible for balancing emotional manifestations.
The temporal lobe of the non-dominant hemisphere is responsible for:
- facial expression recognition;
- analyzes speech intonation;
- regulates the perception of rhythm;
- responsible for the perception of music;
- promotes visual learning.
Left temporal lobe and its damage
The left, as a rule, dominant share, is responsible for logical processes, contributes to understanding of speech processing. She is assigned the role of control over the character, remembering words, she is associated with short-term and long-term memory.
If a disease or damage is localized in the temporal lobe of the brain of the dominant hemisphere, this is fraught with consequences in the form of:
- aggression towards oneself;
- the development of melancholy, which manifests itself in endless pessimism, thoughts of meaninglessness and negativity;
- paranoia;
- difficulties in arranging phrases in the process of speech, selection of words;
- the difficulties of analyzing incoming sounds (the inability to distinguish crackling from thunder, etc.);
- reading problems;
- emotional imbalance.
Activity rate
As you know, the temporal lobe is at the level of the imaginary temple of glasses - that is, on the line below the level of the ears. The temporal lobes combined with the activity of the limbic system make life emotionally intense. Their unity allows us to talk about the emotional brain, which is known for passionate desires and sublime experiences. These experiences make us feel the peak of pleasure or leave us in deep despair.
Normally, with a balanced activity of the temporal lobes and the limbic system, a person has full self-awareness, relies on personal experience, experiences a variety of uniform emotions, is prone to experiencing spiritual experience, is aware of everything. Otherwise, all of the listed activities of the human brain will be disrupted, and, therefore, problems in communication and everyday life cannot be avoided.
Damage to the non-dominant hemisphere
The peculiarity of the location of the temporal lobes is the reason why this part of the brain is so vulnerable.
Emotional intelligence makes life meaningful and colorful, but as soon as it gets out of control, it shows cruelty, pessimism, and oppression from the depths of consciousness that threaten us and others. Emotional intelligence is the most important element of the operating system of our self. In psychiatry, the ailments associated with these brain regions are called temporal epilepsy, but in addition, the disorder in the activity of these brain regions can explain many irrational manifestations of the personality and, unfortunately, religious experience.
If the non-dominant hemisphere of the temporal lobe of the brain is damaged, emotional speech is not correctly perceived, music is not recognized, sense of rhythm is lost, and there is no memory for facial expressions.
The explanation of the so-called extrasensory abilities may well consist in convulsive seizures when the functions of the temporal lobes of the brain are impaired.
Manifestations:
- deja vu - feeling already seen before;
- perception of the unseen;
- a condition like transcendental or sleep;
- inexplicable states of inner experiences that can be regarded as merging with another consciousness;
- conditions characterized as travel to the astral plane;
- hypergraphy, which can be manifested by an unbridled desire to write (as a rule, meaningless texts);
- recurring dreams;
- problems with speech when the ability to express thoughts disappears;
- sudden rush of depressive irritation with thoughts about the negativity of everything around.
Brain disorders
Unlike epileptic conditions, which are caused by dysfunction of the right temporal lobe of the brain, the feelings of an ordinary person appear systematically, rather than irregularly.
As a result of voluntary testing, it was revealed that the forced activation of the temporal lobes of the brain is felt by a person as supernatural experiences, sensations of the presence of a non-existent object, angels, aliens, and also a sensation of a transition beyond life and approaching death was recorded.
Awareness of the double or the “other Self” arises due to a mismatch of the cerebral hemispheres, according to experts. If you stimulate emotional perception, extraordinary, so-called spiritual experiences arise.
A passive temporal lobe hides intuition, it is activated when there is a feeling that someone you know is not good, although you don’t see them.
Among patients suffering from an ailment of the middle sections of the temporal lobe, there were cases of the highest emotionality, as a result of which highly ethical behavioral manifestations developed. In the behavior of patients with hyperactive convolutions of the temporal lobe, fast and coherent speaking was observed, and at the same time, a relative decrease in sexual activity was noticeable. Unlike other patients with a similar type of disease, these patients showed signs of depression and bouts of irritability, which contrasted with their friendly attitude.
Prerequisites for increased activity
Various events can play the role of an irritant in the temporal lobe. Increased activity (convolutions of the temporal lobe) is possible due to events related to the accident, lack of oxygen at high altitude, damage during surgery, a jump in sugar level, prolonged insomnia, drugs, manifestations of the temporal lobe itself, altered state of consciousness after meditation, ritual actions.
Limbic bark
In the depth of the lateral groove in the temporal lobe is the so-called limbic cortex, resembling an islet. A circular groove separates it from adjacent adjacent sections from the side. On the surface of the islet, the front and rear parts are visible; the taste analyzer is localized in it . The inner and lower parts of the hemispheres are combined into the limbic cortex, including the amygdala, olfactory tract, and sections of the cerebral cortex .
The limbic cortex is a single functional system, the properties of which are not so much in providing a connection with the external, as in regulating the tone of the cortex, the activity of internal organs, and behavioral reactions. Another important role of the limbic system is the formation of motivation. The inner impulse includes instinctive and emotional components, the regulation of sleep and activity.
Limbic system
The limbic system simulates an emotional impulse: negative or positive emotions are its derivatives. Thanks to its influence, a person has a certain emotional attitude. If her activity is reduced, optimism prevails, positive feelings, and vice versa. The limbic system serves as an indicator for assessing ongoing events.
These brain regions have a strong charge of negative or positive memories recorded in the registry of the limbic system. Their importance is that when looking at events through the prism of emotional memory, the ability to survive is stimulated, the resulting motivation stimulates action when it comes to engaging in relationships with the opposite sex, or avoiding a dysfunctional boyfriend, who was recorded in memory as bringing pain.
The emotional background, negative or positive, creates a sum of emotional memories that affect stability in the present, attitudes, behavior. The deep structures of the limbic system are responsible for building social ties and personal relationships. Based on the results of the experiments, the damaged limbic system of rodents did not allow mothers to show tenderness to their offspring.
The limbic system functions like a switch of consciousness that instantly activates emotions or rational thinking. With a calm limbic system, the frontal cortex becomes dominant, and when it dominates, emotions control the behavior. In depressive conditions in humans, the limbic system is usually more active, and the work of the head cortex is inhibited.
Diseases
Many researchers have found a decrease in the density of neurons in the large temporal lobes of patients who were diagnosed with schizophrenic diseases. According to research results, the right temporal lobe was larger in comparison with the left. With the course of the disease, the temporal part of the brain decreases in volume. At the same time, increased activity in the right temporal lobe and a violation of the connections between neurons of the temporal and head cortex are noted.
The indicated activity is observed in patients with auditory hallucinations, perceiving their thoughts as outside voices. It was noted that the stronger the hallucinations, the weaker the connection between the departments of the temporal lobe and frontal cortex. Disorders of thinking and speech are added to visual and auditory abnormalities. The superior temporal gyrus of schizophrenia sufferers is significantly reduced with the same part of the brain in healthy people.
According to many authors, the pathological process gradually spreads from the depth of the brain to the frontal and temporal parts, most pronounced in the upper gyrus of the right temporal lobe.
Hemisphere Health Prevention
As a prevention of full perception of the brain, training in the form of music, dancing, declaring poetry, playing rhythmic melodies is necessary. Movement to the beat of music, singing to the play of musical instruments improves and harmonizes the functions of the emotional part of the brain when the temporal lobe is activated.
