Can you read and write? Do math? Put on your shoes? Read a map? Apply lipstick or know when someone is unhappy? Catch a ball?
If so, thank your Parietal lobes!!!
- The parietal lobe is complex in that there is a dominant hemisphere and a non-dominant hemisphere. The parietal lobe controls abilities such as math calculation, writing, left-right orientation, and finger recognition. Lesions in part of the parietal lobe can cause deficits in writing, arithmetic calculation, left-right disorientation, and finger-naming (Gerstmann syndrome).
- The nondominant parietal lobe controls the opposite side of the body enabling you to be aware of environmental space, and is important for abilities such as drawing, being aware of expression, body language and facial recognition. If you can recognize feelings on someone’s face, be grateful to your parietal lobe near the temporal lobe. .An acute injury to the nondominant parietal lobe may cause neglect of the contralateral side (usually the left), resulting in decreased awareness of that part of the body, its environment, and any associated injury to that side (anosognosia). For example, patients with large right parietal lesions may deny the existence of left-sided paralysis. Patients with smaller lesions may lose the ability to do learned motor tasks (eg, dressing, other well-learned activities)—a spatial-manual deficit called apraxia.
Parietal lobe functions include:
- Information Processing
- Touch Sensation (Pain, Temperature, etc.)
- Understanding Spatial Orientation
- Movement Coordination
- Visual Perception
- Reading and Writing
- Mathematical Computation
Training with Neurofeedback can assist the brain in making new pathways and support the brain in rewiring itself. Schedule your free demo today to learn more about how Neurofeedback can bring you to a higher state of awareness and function. For the first time in history, we can see our own brains at work and assist its functioning to a higher state of optimization.
I look forward to working with you!
In general, the average human brain weighs about 1,400 grams (3 lb). The brain looks like a large pinkish-gray walnut. The brain can be divided down the middle lengthwise into two halves called the cerebral hemispheres. Each cerebral hemisphere is divided into four lobes by sulci and gyri. The sulci (or fissures) are the grooves and the gyri are the “bumps” that can be seen on the surface of the brain. The folding created by the sulci and gyri increases the amount of cerebral cortex that can fit in the skull. The total surface area of the cerebral cortex is about 324 square inches or about the size of a full page of newspaper. Each person has a unique pattern of gyri and sulci, much like a fingerprint.
The third lobe of the brain for this series is the occiptal lobe which is located at the back of your head. It is where visual input in the brain is translated into information of what your eyes are seeing, and also to being able to understand what we read.
Similar to how the temporal lobe makes sense of auditory information, the occipital lobe makes sense of visual information so that we are able to understand it. If our occipital lobe is impaired, or injured we would not be able to correctly process visual signals, thus visual confusion would result. We might, for example, see an image chopped up or parts missing. Also, with back of the head injuries, our ability to get into a restorative sleep called REM sleep is often impaired.
Occipital lobe epilepsy accounts for about 5-10 of all epilepsy. An occipital lobe epilepsy may be triggered by a strobe light show since the origin is in the visual processing component of the brain.
Where is it? It’s the front and top of your head
What does it do? This part of the brain handles thinking, decision- making, and planning.
You use your frontal lobe nearly everyday. You use it to make decisions, such as what to eat or drink for breakfast in the morning. It’s where you make a plan for your day, and concentrate on your “To Do” list. It’s where your personality is formed and why when a person has an accident or injury to the frontal lobe people notice a change to a person’s personality.
Here is a little neuroscience history:
In the mid 1800s, Phineas Gage, a railroad worker, somehow miraculously survived an accident where a large iron pole was driven into his head, specifically into the frontal lobe. After the incident, Gage’s personality was said to have changed dramatically. His friends and family said that the once kind and hard-working Gage had changed into a lazy and rude man until he died years later. However, this incident allowed doctors and psychologists to analyze the brain and see the importance and functions of the frontal lobe.
Four simple periodic rhythms recorded in the EEG are alpha, beta, delta, and theta. These rhythms are identified by frequency (Hz or cycles/sec) and amplitude. The amplitudes recorded by scalp electrodes are in the range of microvolts (μV or 1/1,000,000 of a volt).
Alpha: The four basic rhythms have been associated with various states. In general, the alpha rhythm is the prominent EEG wave pattern of an adult who is awake but relaxed with eyes closed. Each region of the brain had a characteristic alpha rhythm but alpha waves of the greatest amplitude are recorded from the occipital and parietal regions of the cerebral cortex. In general, amplitudes of alpha waves diminish when subjects open their eyes and are attentive to external stimuli although some subjects trained in relaxation techniques can maintain high alpha amplitudes even with their eyes open.
Beta: Beta rhythms occur in individuals who are alert and attentive to external stimuli or exert specific mental effort, or paradoxically, beta rhythms also occur during deep sleep, REM (Rapid Eye Movement) sleep when the eyes switch back and forth. This does not mean that there is less electrical activity, rather that the “positive” and “negative” activities are starting to counterbalance so that the sum of the electrical activity is less. Thus, instead of getting the wave-like synchronized pattern of alpha waves, desynchronization or alpha block occurs. So, the beta wave represents arousal of the cortex to a higher state of alertness or tension. It may also be associated with “remembering” or retrieving memories.
Delta and Theta: Delta and theta rhythms are low-frequency EEG patterns that increase during sleep in the normal adult. As people move from lighter to deeper stages of sleep (prior to REM sleep), the occurrence of alpha waves diminish and is gradually replaced by the lower frequency theta and then delta frequency rhythms.
Although delta and theta rhythms are generally prominent during sleep, there are cases when delta and theta rhythms are recorded from individuals who are awake. For example, theta waves will occur for brief intervals during emotional responses to frustrating events or situations. Delta waves may increase during difficult mental activities requiring concentration. In general, the occurrence and amplitudes of delta and theta rhythms are highly variable within and between individuals.

Non-invasive QEEG Brain Mapping is analogous to a physician performing a throat culture on a patient with a throat infection to determine which antibiotic would best eradicate the infection. Brain Mapping gives answers to what’s going on below the surface. The electrodes are placed on the head, and read the electrical activity coming off of the brain.
The Brain Map analysis gives us important information to more effectively help improve the quality of life and productivity of each individual patient. Each segment of the brain produces brain wave activity that can be measured and will indicate the level of functioning of that region. Treatment is then guided by the map. A brain map is done prior to treatment and after about 10 sessions.
QEEG (Quantitative Electro- encephalogram) or Brain Mapping is an essential diagnostic procedure for developing non-drug treatment protocols for Attention and focus issues, Autism, Learning Disorders, Anxiety, Depression and Stress Related Illnesses.
In a safe, spa-like space you will sit comfortably for about an hour with a non-invasive electrode cap on your head while we take a reading of the brain’s activity. This map will then guide our treatment for your sessions.
