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

Distinctiveness between the right and left hemisphere of the brain Word Count: 995 Abstract The brain assymetry experiment is to investigate on the distinctiveness of the right and left hemisphere in the brain as each hemisphere has certain specializations. The experiment were carried out by initially asking the 25 participant on whether they were left or right handed and they had to choose the chimeric image which appeared younger to them. Laterality quotients were calculated in order to

Broca’s area is the portion of the brain in charge of speech‚ language processing and comprehension‚ and controlling facial neurons. We know this‚ and much more concerning the Central Nervous System‚ thanks to Dr. Paul Pierre Broca who made these discoveries over one hundred and fifty years ago. Pierre Paul Broca was born in 1824 to parents who initially would not allow Broca to pursue an academic career. However‚ with the immense success he gained while completing his studies‚ his mother agreed

They also supply nutrients and oxygen‚ perform clean up tasks‚ and insulate one neuron from another so that their neural messages are not scrambled.

I was walking down the trail to Sombrio Beach which is about a 1.5k hike down a steep trail to the ocean. I had a surfboard under my right arm‚ an axe in my left hand‚ and a large 40 litre hiking backpack fully loaded with supplies on my back. About half way down there is a left turn in the trail which has a declining

Humans have a blind spot because the spot that the axons meet to form the optic nerve does not have any sensor cells. 2. Describe the functional and anatomical differences between rods and cones: a. Rods: Respond to faint light and are more abundant in the periphery of the eye. Cylindrical shape‚ similar to a welding rod. b. Cones: Responsible for color vision
