A self-regulation therapy that teaches patients how to control their brainwaves (as detected by EEG) by controlling their arousal levels. Some evidence suggests it may help with easing behavioral symptoms caused by head trauma, as well as ADHD and chronic stress.

Electroencephalogram (EEG) Neurofeedback

Situated directly behind the frontal lobe, the parietal lobe is primarily responsible for processing sensory information from various parts of the body. A key structure within this lobe is the somatosensory cortex, which is essential for this function.

Parietal Lobe

Situated on the side of the head near the temples, the temporal lobe is a region of the brain involved with several key functions, including hearing, memory, emotion, and certain language abilities. It houses important structures for these functions, such as the auditory cortex, which processes sound, and Wernicke's area, which is crucial for language comprehension.

Temporal Lobe

Situated at the posterior end of the brain, the occipital lobe is primarily responsible for interpreting visual information. It contains the primary visual cortex and is characterized by a retinotopic organization, meaning there is a direct correspondence between an object's position in the visual field and its representation on the cortex.

Occipital Lobe

Located at the front of the brain and extending back to the central sulcus. It receives signals from all senses in order to coordinate them. Also involved in reasoning, motor control, emotion, language, and higher cognitive functions such as thinking, speech and problem solving.
It contains Broca's area, the Prefrontal Cortex, and the Motor Cortex.

Neurofeedback: A comprehensive review on system design, methodology and clinical applications

Components of measuring neurofeedback include:

- Hertz (Hz)
- Microvolts (μV)

Components of Neurofeedback Frequency

This has a frequency of 3.5 to 7.5 hz and relates to slow activity. It connects to creativity, daydreaming, memory, emotion, sensation, reflection, meditation, and spiritual awareness. It’s the state that lies between being awake and asleep. Theta activity is abnormal in awake adults, but normal in children up to age 13. It reflects activity from the limbic system and hippocampus. If it works properly it can aid in learning.

EEG Theta

Beta activity has 14 or greater Hz and is seen as fast activity. It tends to be the dominant brain wave in those who are alert, anxious, or have their eyes open. It relates to problem solving, decision-making, and processing information. Because it’s wide, it’s divided into three sections, including low, midrange, and high. 

EEG Beta

Delta waves have 0.1 to 3 Hz; and have the lowest frequency, highest amplitude, and slowest speed out of all the brainwaves. They are involved in deep sleep, specifically stages 3 and 4, and are the dominant brainwaves in infants. They reduce awareness of the tangible world, and allow people to access subconscious information. Peak performers reduce delta waves while focusing.

EEG Delta

Alpha is between 8 to 12 Hz and peaks at 10 Hz. It is associated with calmness, positive emotion, extroversion, creative problem-solving, mental work, and accurate perceptions of the world. It allows us to apply classroom learning to the real-world, and lets us to transition between tasks. It is the major rhythm in most relaxed adults, and starts being more prominent at age 13. Alpha brainwaves come from white matter in the brain, which is viewed as joining all parts of the brain together.

EEG Alpha 

Gamma is between 30 to 44 Hz, and is the only brainwave found in all parts of the brain. It deals with information processing involving multiple areas of the brain, as well as memory. Reduced Gamma is associated with learning disabilities. 

EEG Gamma

This method involves placing 21 electrodes, with 19 recording the cortical regions, and 2 serving as references. The 10-20 method refers to placing electrodes in 10-20% increments across regions of the skull.

EEG Electrode System 10-20

Types of neurofeedback include:
-	Frequency/power neurofeedback
-	Slow cortical potential neurofeedback (SSCP-NF)
-	Low-energy neurofeedback system (LENS)
-	Hemoencephalographic (HEG)
-	Live Z-score neurofeedback
-	Low resolution electromagnetic tomography (LORE-TA)
-	Functional magnetic resonance imaging (fMRI)

Types of Neurofeedback

Pros of neurofeedback therapy include it's safe, non-invasive, and it can improve several conditions.

Pros of Neurofeedback 

Cons of neurofeedback therapy include that there is inconclusive scientific evidence on its effectiveness, it's expensive, it is not covered by many insurance companies, it takes longer to see improvement, and the benefits are short-term.

Brain Lobe Considerations When Using Neurofeedback

Housed within the parietal lobe, the somatosensory cortex is crucial for processing a range of sensory information from across the body, including touch, temperature, and pain. This area of the brain is organized such that distinct regions are dedicated to processing sensations from different parts of the body.

Somatosensory Cortex

Damage to the parietal lobe can cause a condition where ignore objects in one half of there visual field (they are not aware of it). 

Unilateral neglect

The left hemisphere relates to problem solving, math, advanced grammar, attention, and association. 

Left Hemisphere of Parietal Lobe

The right hemisphere connects to spatial awareness, and geometry.  

Right Hemisphere of Parietal Lobe

Considerations with the parietal lobes include:
- Sense of direction
- Learning disorders
- Dyscalculia

Parietal Lobes Associated Conditions 

Based on the information provided in the case study, which of the four major lobes of the cerebral cortex is most likely damaged? Justify your answer by explaining the connection between the patient's symptom and the primary function of that lobe.

Identifying Brain Function Through Deficits

Located in the fusiform gyrus on the underside of the temporal lobe. When damaged, people can get prosopagnosia (inability to recognize faces).

Fusiform face area (FFA)

Among many theories, there is consensus surrounding the understanding that medial temporal lobe damage only harms certain types of memory and learning, leaving repetition priming, classical conditioning, and reinforcement-learning largely untouched. Many models also agree about organization of the medial temporal lobe.

Consensus About the Medial Temporal Lobe Among Memory Theories

Located at the bottom of the temporal lobe. It likely plays a major role in our ability to generate meaning from sensory input and affects our understanding of many topics.

Anterior Temporal Lobe (ATL)

Conditions associated with the temporal lobes include:

- Anger
- Rage
- Dyslexia
- Long-term memory
- Closed head injury 

Temporal Lobes Associated Conditions

Located in the temporal lobe, the auditory cortex is the primary brain region for processing auditory information. It serves as the final destination in the main auditory pathway, receiving neural signals that have been relayed through the inferior colliculus and the medial geniculate nucleus of the thalamus.

Auditory Cortex

Located within the temporal lobe, Wernicke's area is a critical region for the comprehension of speech. Damage to this area can result in a specific type of language deficit where an individual can still produce sensible-sounding language but loses the ability to understand what is being said.

Wernicke's Area

The hippocampus, a structure within the temporal lobes, is central to learning and memory. It is essential for consolidating new information into long-term memory, a process that involves transferring new learning for permanent storage. Research has shown its specific involvement in normal recognition memory and spatial memory, as demonstrated in studies where rats with hippocampal lesions showed impairment in tasks like object recognition and maze running. Furthermore, the hippocampus projects information to cortical regions, which helps to give memories meaning and connect them with other memories. It is also critical for contextualized emotional learning. The famous case of patient H.M., who could not form new memories after his hippocampus was removed, provided significant evidence for its role.

Hippocampus

Based on the patient's symptoms, which major region of the brain, located on the side of the head, is most likely damaged? Explain your reasoning by connecting specific symptoms to the known functions of this region.

Clinical Symptom Analysis

Considerations associated with the occipital lobes include:
- Learning disorders 

Occipital Lobes Associated Considerations

Refers to the direct correlation between the location of an object in a person's visual field and the corresponding position of its representation on the cortex.

Retinotopic Organization

Located within the occipital lobe, the primary visual cortex is the principal area of the brain dedicated to interpreting incoming visual information.

Primary Visual Cortex

Based on the information provided in the case study, which major brain area is most likely affected, and what is its primary role that accounts for these specific symptoms?

Neurological Symptom Analysis

A patient is admitted to the hospital after a significant blow to the very back of their head. A preliminary examination shows their eyes are physically undamaged and are reacting normally to light. However, the patient has great difficulty recognizing familiar objects and faces, reporting that they can 'see' but cannot understand or interpret what they are looking at. Based on the location of the injury and the specific symptoms, which major brain area is most likely affected? Justify your answer by explaining the connection between this area's primary function and the patient's visual difficulties.

Brain Injury Symptom Analysis

Contained in the left hemisphere of the frontal lobe of the brain and specialized in producing speech. People with damage to Broca's area can't speak fluently.

Broca's Area

A part of the frontal lobe that is responsible for higher-level cognitive functioning and focuses on "in the moment" or rash behavior (decision-making, problem solving, and so on). This area is also responsible for the development of personality. The PFC has a handful of (not universally agreed upon) subdivisions:

- Dorsomedial
- Dorsolateral
- Ventromedial
- Ventrolateral
- Orbitofrontal

Prefrontal Cortex (PFC)

The left hemisphere deals with working memory, concentration, executive planning, and positive emotions. 

Left Hemisphere of Frontal Lobe

The right hemisphere of the frontal lobe is involved in several cognitive functions, including episodic memory, social awareness, and the retrieval of information. It also contains the primary motor centers that control voluntary movement on the left side of the body, meaning damage to this area can lead to motor impairment on the contralateral side.

Right Hemisphere of Frontal Lobe

The motor cortex is the part of the frontal lobe which is involved in planning and coordinating movement.

Motor Cortex

Phineas Gage, a 25-year-old railroad foreman in 1848, is one of the most renowned cases in neuroscience. He suffered a severe brain injury when an explosion drove a tamping iron through his face and skull, damaging his frontal lobe. Miraculously, Gage survived the accident, remaining conscious and able to walk and speak immediately after. However, in the following months, he underwent a profound personality transformation. Previously known as a well-mannered man, he began to exhibit strange and inappropriate behavior. This shift in personality is attributed to a loss of impulse control, a key function managed by the frontal lobe.
