Analysing research has demonstrated a large number of perspectives on hemispheric preference of facial recognition. The right hemisphere is indicated to be the part of the brain responsible for processing visual information in comparison to the left hemisphere which is more for language and analytical processing. Studies such as the preference test have reinforced this. Other studies on hemispheric preference include examining emotions‚ facial memory‚ facial features encouraging hemispherical preference

In class were briefly touched on the subject of mirror neurons‚ which are neurons that fire when an animal acts or observes the same action done by another. We learned that these neurons exist primarily in the ventral premotor cortex F5 areas of a monkey’s brain. Experiments proved that neurons in the VPC F5 area fire when a monkey does an action‚ but also fire when a monkey watches a human do the same action. However‚ when the monkey watches the human just carry out the motions of the action‚ not

Free will is fundamental to human existence (Arnason‚ 2011). Neuroscience implies that free will is not a defining feature of humanness‚ but is in fact an illusion concealed by biochemical complexity (Burns & Bechara‚ 2007). Developments in neuroscience have led us to question our views about whether we have conscious free will (Heisenberg‚ 2009; Nahmias‚ 2009; Smith‚ 2011). Various experiments into the phenomenon appear to show that we do not have conscious free will‚ however these experiments have

Unit 4222-237 Dementia awareness (DEM 201) 1.1 Dementia is a loss of brain function. If affects memory‚ thinking‚ language‚ judgement and behaviour. Dementia is progressive‚ so the symptoms will gradually get worse. In a later stage of dementia people will find it hard to carry out daily tasks and will come dependant on other people. 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

Introduction The cingulate gyrus is a stretch of cortex directly dorsal to the corpus callosum and can be split into multiple areas: the anterior cingulate cortex (ACC)‚ middle cingulate cortex‚ and posterior cingulate cortex (PCC). Each of these subsections has different structural characteristics and neuronal projections that characterize their individual cortical areas and functions (Stevens et al.‚ 2011). The ACC has been functionally tied to several behaviors‚ including decision-making‚ socially

When one thinks of psychopaths‚ they may think of serial killers such as Ted Bundy or Albert Fish. The reality is that psychopaths come in all forms and are much more common than one would think. A psychopath can be defined by a combination of multiple traits‚ such as lacking conscience‚ empathy and remorse‚ and irresponsibility and impulsiveness. This disorder is a type of antisocial personality disorder. Psychopathy is also a spectrum disorder‚ where psychopaths can exist anywhere on the spectrum

The purpose of this study was to see if a person is able to function normally when the left and right hemispheres of the brain are separated and can no longer communicate. To test this Gazzaniga and Sperry had run different experiments to test the visual‚ tactile‚ and auditory abilities of split-brain patients who had surgically severed the corpus callosum which allowed for the two hemispheres of the brain to communicate. To test their visual abilities patients had sat in front of a board with a

PSYC3209: Cognitive Neuroscience 2012 Q2. Discuss the neural mechanisms that underlie value-based decision making. Consider a situation where a choice needs to be made between hunting for food and seeking a warm shelter. To decide between these two fundamentally different rewards‚ the brain needs to calculate the values and costs associated with each option‚ consider different motivational‚ cognitive and contextual variables‚ construct a plan to obtain reward outcomes‚ and finally input these

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
