Functional Magnetic Resonance Imaging Analysis

23.The part of the limbic system located in the center of the brain, this structure relays sensory information from the lower part of the brain to the proper areas of the cortex and PROCESSES some sensory information before sending it to its proper area and is called the thalamus.

The parietal lobes are located behind the frontal lobes and in front of theoccipital lobes. They process sensory information such as temperature, pain,taste, and touch. In addition, the processing includes information about numbers, attentiveness to the position of one 's body parts, the space around one 's body, and one 's relationship to this space.

This division is not based on functionality, but is an aesthetic one. The frontal lobe is the largest of these geographic areas with the Rolandic fissure (Central sulcus) and the Silvian fissure (Lateral sulcus) and the Corpus Callosum creating the boundaries. The frontal lobe is comprised of three functionally specific areas on the surface area of the cerebral cortex: the precentral cortex or primary motor cortex (Brodmann’s area 4), the premotor cortex (Brodmann’s area 6) and the prefrontal

* Electrocenphalogram- Detects electrical activity in the brain while awake or asleep. The brain cells communicate 24/7 via electrical impulses.

Two brain structures that could likely be affected by this damage are the frontal lobes and the temporal lobes. The frontal lobe produces speech, controls motor skills, and initiates leading functions such as thinking, personality, emotion and memory. (Huffman, K., Dowdell, K. 2015. Pg. 71). The temporal makes it possible for an individual to hear properly, comprehend language, recollect thoughts, and maintain emotional stability; this lobe also contains the auditory complex, which is responsible for the interpretation

The parietal lobe is located in the middle section of the brain and is associated with processing tactile sensory information such as pressure, touch, and pain.

The parts of the brain that are involved in the chemical sense of taste are the parietal lobes. The parietal lobe is behind the

The brain stem or the medulla is the closest to the spinal cord. The brainstem is responsible for most of the human bodily functions. The brain stem is critical for human survival and normal human functions. The brain stem is also responsible for information of pain and touch from the head and neck; it is also responsible for the inputs from the face and the mouth. Reticular formation is a group of neurons, nuclei, that are important for sleep and wakefulness. In reticular formation there is nuclei that are a major source of neurotransmitter serotonin. Serotonin is important for regulating mood and activities.

c. One study showed a 37% reduction of the brain’s activity in the parietal lobe that processes cognitive, memory, information regarding the driving task, sense of direction and “spatial sense” as well as the occipital lobe that processes the visual information (Aker, 2011).

According to Lu and Bludua, the outer layer of the cerebral hemisphere is called the cerebral cortex, which is the outer layer of the brain. Under the cortex is the limbic system, which consists of the amygdala, hippocampus, thalamus, and hypothalamus. In the temporal lobe, the amygdale purpose is to store and process strong feeling such as fear. Behind the amygdala is the hippocampus, which channels making memories and learning into short term memory. Then short term memory converts into long term memory. On the top of the brain stem is the thalamus. The thalamus is the “central processing center of the limbic system” (Lu & Bludau, 2011) which accumulates, processes, and distributes limbic and sensory information to the cerebral cortex. Beneath the thalamus is the hypothalamus. The hypothalamus maintains homeostasis and the body’s equilibrium. To keep the system at a set point, the equilibrium monitors body temperature, blood pressure, body weight, fluid

The frontal lobe is near the parietal lobe and is above and in front of the temporal lobe. The frontal lobes are linked to sensory and memory centers throughout the brain. Their primary job is to allow us to think things through and determine how to use information that is located elsewhere in the brain.

The parietal lobe is responsible for our motor co-ordination; motor impulses to the muscles are

2. Functional brain mapping (scanning a person's brain while he or she is performing a certain physical task such as squeezing a ball, or looking at a particular type of picture) is helping researchers better understand how the brain works.

The brains electrical activity is able to be measured with an electroencephalograph (EEG). The EEG measures your brain activity or brain waves. When you are awake and alert you exhibit beta waves which are small and fast, but immediately before sleep and when you are relaxed and allowing your mind to wander you exhibit alpha waves (2).
