the existence of different stores in memory which are the sensory memory‚ the STM‚ and the LTM. These scans have shown that the prefrontal cortex is active when people are working on an immediate task which is STM. The scans also show that the hippocampus is active when the LTM is being used‚ and this was further proved when there was a study of HM (1966)‚ who has both of his hippocampi removed because of a tumour‚ and after this he was no longer able to form any new Long-term memories‚ but was still

Key words: Episodic Memory; Hippocampus; Binding; Recruitment Abstract The memorization of events and situations (episodic memory) requires the rapid formation of a memory trace consisting of several functional components. A computational model is described that demonstrates how a transient pattern of activity representing an episode can lead to the rapid recruitment of appropriate circuits as a result of long-term potentiation within structures whose architecture and circuitry match those of

Neurons travel everyday in millions to carry out different task. It’s fascinating how they travel as if they are traveling across the country. They’re following cues along the way that are telling them exactly where to go. Evidence shows that young neurons have an idea

Introduction Childhood traumas have been associated with many psychological problems later in life. Specifically‚ sexual abuse during childhood shows correlations with many different types of anxiety disorder. There are many theories as to why this is‚ but most of the prominent ones deal with memory repression. Freud first introduced memory repression when he described it as consciously taking an event out of their memory. Since the population of child sexual abuse survivors is to be 1 in 5 girls

THC receptors are abundant in the brain but they are concentrated in certain areas. One region of the brain where THC receptors are highly concentrated is the hippocampus. The hippocampus is the area of the brain that processes memory. When THC attaches to receptors in the hippocampus‚ it weakens short-term memory. The hippocampus also communicates with other regions of the brain that process new information into long-term memory. So under the influence of marijuana‚ new information may never

portion of the brain has been affected. In the romantic comedy‚ Lucy is the main character who suffered a brain injury in a car accident. Her main symptom was loss of short-term memory. This is caused by damage to the hippocampus‚ inside the temporal lobe‚ as the hippocampus controls memory functions. The character Oola is a friend of Henry Roth‚ whom helps come up with clever ideas to help Lucy fall in love with Henry everyday. Oola is affecting his neurotransmitters by the daily use of

Neurotransmitter – They are brain chemicals that communicate throughout the body. Amygdala – It is located in the cerebral hemisphere that looks like a grey almond shape‚ it controls the emotions we have from hormones‚ arousal and emotional memories. Hippocampus – This is in the medial temporal lobe it’s a small organ and is very important to the limbic system‚ it is what helps with our long term memory. Corpus Callosum – Located in the middle of the brain the corpus callosum is a big ball of neural fibers

researcher will test how mildly jogging 804.672 meters on a neighborhood sidewalk will affect the memory ability of a 12 year old male. This research will give the researcher background information on how jogging will affect a 12 year-old’s memory and hippocampus volume‚ as well as the brain itself. The results will help to validate that jogging will increasingly affect a 12 year-old’s memory ability from using a number grid test as the testing tool. The human memory is a process that involves a constant
