survival for almost all species including humans. This manoeuvring is mainly dependent on learning and remembering locations. The allocentric navigation involves mainly the hippocampus (Vorhees et al‚ 2014). Lesions‚ pharmacological inhibition‚ long-term potentiation (LTP) saturation‚ the act of learning itself within the hippocampus can result in impaired spatial learning and memory (Whitlock et al‚ 2006 and Suh et al 2011).

I strongly believe that short term memories can lead into long term memories‚ but only if the human right frontal lobe‚ hippocampus‚ and the sensory region works together. Do you remember the time you were in class and had a question to ask your professor? You raise your hand and when the professor calls your name‚ you simply say “I forgot what I was going to say” or “I don’t

Navigation-Related Structural Changes in the Hippocampi of Taxi Drivers. Background Information The hippocampus is a brain structure that is involved with memory‚ spatial awareness and navigation. For memory‚ the hippocampus is linked to the conversion of information from short-term memory to more permanent memory. From studying a man known as HM‚ we know that the impact of a damaged hippocampus is that memories from the past are retained‚ but new memories are not stored. For example a person

the role of the hippocampus in spatial memory. Localisation is a theory that different parts of the brain are responsible for certain behaviours or functions. The hippocampus is located in the medial temporal lobe of the brain‚ and is associated with memory and spatial navigation. Maguire’s study provides some insight into the localisation of these functions in the hippocampus. Maguire’s study was a natural experiment‚ aiming to see if spatial memory was localised in the hippocampus. The procedure

xxLEARNING AND MEMORY Learning is the process of gaining knowledge or skills through study‚ experience or teaching. It is a process that depends on experience and leads to long-term changes in the possible behaviour of an individual in a given situation‚ in order to achieve a goal. Memory is a property of the human mind. It describes the ability to retain information. There are different types of classifications for memory based on duration‚ nature and retrieval of items. The generally accepted

Measurements of brain and hormone activity in PTSD patients can help inform Western medical treatments‚ psychotherapy and Chinese Medicine alike. Aside from the impact on pharmacological studies‚ brain activity can provide insight into new therapies like EMDR and neurofeedback.

skills. The disease comes on gradually‚ as two abnormal protein fragments called Plaques and Tangles accumulate in the brain and kill brain cells. All of this usually starts in the hippocampus‚ the part of the brain where memories are first formed. Over many years the Plaques and Tangles slowly destroy the hippocampus and it becomes harder and harder to form new memories. Simple recollections from a few hours or days ago that most people take for granted are just not there. After that‚ more plaques

UNDERSTANDING HOW KEY FUNCTIONS OF THE BRAIN ARE AFFECTED BY DEMENTIA You do not have to become an expert on the brain to be a good dementia health care worker. However‚ having a basic awareness of the brain’s functioning may help you to understand some of the difficulties a person with dementia is experiencing. It can also help to explain some of the behaviours you may find challenging and difficult to comprehend. The level of damage taking place in the brain (‘neurological impairment’)

The brain damage causes Lucy to suffer from short-term memory loss.

memories after such an event. Lack of oxygen damages brain cells heavily‚ and due to an inability to regenerate‚ permanent memory loss may occur‚ depending on the severity of damage. Alcohol disrupts brain cells‚ specifically cells of the hippocampus. Because the hippocampus is responsible for long-term and short-term memory‚ extreme consumptions of alcohol over a long period can cause degradation. Parkinson’s disease is a known factor for causing memory loss because of its slow destruction of dopamine
