HOW CAN BRAIN IMAGING HELP STUDY COGNITION? Intro * involves analysing activity within brain while performing various cog tasks – allow us to link bhvr & brain function to help understand how info is processed * cog activity assoc w neural activity in brain regions: * on scalp as electrical activity ie MEG‚ EEG (direct measures) * inside brain by measuring O2 consumption caused by neural activity ie PET‚ fMRI (indirect) * diff imaging techniques vary in their temp (time-based)

Compare the Social Brain Hypothesis and the Visual Specialisation Hypothesis The aim of this essay is to investigate the two major theories trying to explain why do primates have large brains. Even since the seminar study of Jerison in 1973 it has been acknowledged that primate brains are unusually large for their body size. There are three main groups of theories giving more or less persuasive explanations of the evolution of large brains and high cognitive skills in primates. The first group

*How does the brain communicate with the rest of the body? How is the autonomic branch of the peripheral nervous system involved in controlling emotions? The nervous system as a whole includes the Central Nervous System‚ consisting of brain and spinal cord‚ and the Peripheral Nervous System‚ whose nerve fibres connect all parts of the body with the central nervous system. The Peripheral Nervous System is further subdivided into two branches‚ the Somatic Nervous system and the Autonomic Nervous System

the organization. Learning organizations are adaptive to their surroundings‚ encourage collective and individual learning‚ constructively utilizes feedback to achieve better results‚ and has enhanced adaptability (Fargo & Skyrme‚ 1995). Applying the brain metaphor to organizations‚ allows us to see how companies operate and how knowledge is shared and disbursed. This metaphor also demonstrates how this knowledge network is critical to the flow of information. Social networking is a key component in

List and explain the four components of Mendel’s hypothesis that led him to deduce the law of segregation. • Alleles make different characters • Two alleles inherited • Dominance and recessive • Alleles segregate in gamete formation First‚ alternative versions of genes account for variations in inherited characters. A gene exists in different versions. Second‚ for each

The author involves statements in his claim to back up his answer‚ he involves statements like how sixteen-years-olds are different medical wise but they are still immature criminal wise meaning they can get off the hook easier. “This is why 16-year-olds are just as competent as adults when

One Brain or Two May 15‚ 2013 In the 1960s Roger Sperry and Michael Gazzaniga conducted human neurological studies in California to determine a better understanding regarding the communication of the brain’s hemispheres. Through their research we have learned many things about human brain function. The experiment involved removing the cause of epilepsy in severely affected individuals by severing the corpus callosum nerve fibers thereby separating left hemisphere from right. Many of the daily motions

All people do not deal with traumatic brain injuries the same in the way that it takes people a different amount of time to recover than others and that it effects the patient’s qualities that they had prior to the injury differently. Traumatic brain injuries are common and they disable 150 million- 200 million people per year which is the leading cause of disability in people under 40 years old by injuring the frontal and temporal lobes. Recovery times are different for different people (most people

Traumatic Brain Injury (TBI) can occur frequently and may cause serious damage. TBI can happen when a bump‚ jolt‚ blow‚ or any head injury causes damage to the brain. MIllions of people a year suffer brain injuries in the United States alone. More than half of those million incidents require the patient to be taken to a hospital because of the severity of the injury. Depending on how severe the injury is‚ it could cause serious brain damage and potentially be life threatening. Half of all TBIs occur
