1.2 The key functions of the brain that is affected by dementia are: · The Frontal lobe; which is to do with behaviour, the person’s personality, interpretation and feelings.

Neuroimaging is also an important mechanism in cognitive psychology. Neuroimaging also known as brain imaging involves “the construction of pictures of the anatomy and functioning of intact brains through such techniques as computerized axial tomography, (CAT, or CT), positron emission tomography (PET), magnetic resonance imaging (MRI) or functional magnetic resonance imaging (fMRI)” (Galotti, 2014).

The frontal lobe is located at the front of the brain and is associated with reasoning, motor skills, higher level cognition, and expressive language.

Abstract Mead & Hampson (1996) developed a study involving the divided visual field paradigm and a phonological rhyme/non-rhyme task to test the speed and accurateness of either side of the brain. This study was used to investigate functional asymmetry between the left and right hemispheres in phonological processing. The research was taken out equally on 15 male and 15 females London Metropolitan University students ranging from ages 18 – 35 years old. They were all specifically chosen to be right–handed and had English as their first language thus providing a fair experiment to see whether our left hemisphere (left side of the brain) or the right hemisphere is faster and more accurate. In conclusion using the mean and standard

For neuroscience to progress, existing investigative techniques must be improved and refined, and new technologies developed. The following discussion explores proposals for enhancing fMRI technology and modifying experimental approaches in animal research in order to advance knowledge in the field. Several new methods can improve temporal and spatial resolution in fMRI.

What impairments would you expect to see following lesions to the ventromedial prefrontal cortex? Compare and contrast with lesions affecting the dorsolateral prefontal cortex.

Nevertheless, abnormalities in ASD during FER can be observed in variety of brain regions apart from FG and amygdala e.g. cerebellum (Critchley et al., 2000), inferior frontal gyrus (Greimel et al., 2010), orbito-frontal and medial-frontal cortices (Loveland, Steinberg, Pearson, Reddoch & Mansour, 2008).

The brain has four main parts: the frontal lobe, temporal lobe, occipital lobe and parietal lobe. Each of these lobes has a distinctive difference between one another. The frontal lobe is known for its ability to help solve problems, behavior, judging someone and coordinated movements. In the temporal lobe, it is formed to help with understanding speech and the ability to hear. For the control of vision, the occipital lobe comes in to help with eye vision. The parietal lobe is known to be the control and relay center for the brain. This is how the brain is able to keep an eye on controlling the body movements. Also, the parietal lobe is the first to know on what is happening to the

anterior aspect of the head, a change in personality and behaviour can occur. The parietal lobe is responsible for our motor co-ordination; motor impulses to the muscles are

Title: Evaluate experimental and brain-imaging techniques and consider what they tell us about the brain and cognitive behaviour in typical and atypical individuals.

The central executive is a system control that determines and changes the information that comes from the subsystems of the phonological loop and the visuo-spatial sketchpad. An example of this is if you were asked what type and how many of each animal do you have. The type of animal would be the visuo-spatial whereas the number of each would be the phonological loop. The central executive system helps use be able to multitask how else would we be able to count animals and know which animals are being counted. People rely heavy on this system to help them remember ting throughout the day not realizing that if the system is being over used it can mix up information and how the person remembers that information.

Using Figure 9.2 (page 226) from Holes, Human Anatomy and Physiology be able to identify the lobes in the brain. Be able to describe the function of each lobe. The lobes of the brain include the following: a. Frontal lobe: It controls a number of higher intellectual processes which includes concentrating, planning, complex

As previously mentioned in this review, PET is a functional imaging technique that uses radio-labelled markers. Thus, it is not suitable for longitudinal studies or for the testing of several cognitive domains within the same experiment. In addition, it has low statistical power which makes its use challenging for group studies, specially. For all these reasons, functional MRI seems a better choice, although specific paradigms (i.e. hierarchical complexity-wise stimuli) need to be designed to allow an unequivocal interpretation of positive

A brief history of brain imaging as described by Raichle (2009) begins with the introduction of computerized tomography (CT) in the early 1970s and development of magnetic resonance imaging (MRI) shortly thereafter, which prompted the invent and use of positron emission tomography (PET), and then functional magnetic resonance imaging (fMRI) which came in the 1990s (p.119). Since then other forms of brain scanning technology have appeared such as the Magnetoencephalography (MEG) scan, and other variations of PET and MRI such as diffusion tensor imaging (DTI). The appearance of these types of brain imaging techniques has provided great insight into the structure and function of the human mind.

Our education system today is in a state of flagrant disrepair. Educators rely on outdated modes of instruction to teach children. Instead of examining these methods administrators spend time and effort developing more intensive assessments in hopes of fueling more intense learning. In order to successfully impact learning
