Hippocampus

In Robert J. McDonald and Norman M. White’s article, “A Triple Dissociation of Memory Systems,” they explain how the memory system works. The memory system is made of three major region areas of the brain: the hippocampus, amygdala, and dorsal striatum. The hippocampus region is to gain information about the relationships between stimuli. Stimuli is an action that alerts physiological or psychological activity (freedictionary.com). In learning areas, this relation sip helps lower doubtfulness…

and thinks it 's the same Sunday which is her also her dad’s birthday. On his birthday, Lucy and her dad always travel up north to get a pineapple, but on that Sunday a stray cow got in the way resulting in a horrid crash. Since Lucy damaged her hippocampus embedded within the temporal lobe in the accident, she cannot make new memories. She clearly remembers everything else that happened in her life before the accident. Her long term memories before the accident are intact which relates to…

result of damage to the hypothalamus and thalamus. The encoding memories are not able to store due to the disrupting in the connection between the hippocampus and cortex. The hippocampus is the switching station for the short term and long term memory. Hippocampus generate the new growing neurons that make the connection in the brain. When the hippocampus damage, the inability of consolidate new memories result in an anterograde amnesia (Coon and Mitterer,…

learned recently is that epilepsy patients, particularly those who have left temporal functioning, find it difficult to come up with words. Seizures in the temporal lobe impacts the hippocampus. While the hippocampus is used for memory, it also impacts language processing as well. If my mom 's temporal lobe and hippocampus were functioning normally, she would not be experiencing a continuous problem in coming up with…

into the mechanisms of amnesia. This work revealed the importance of the amygdala and hippocampus, located in the medial temporal lobe, in explicit memory, a conscious recollection of declarative knowledge. However, his implicit memory, or memory for skills and procedural knowledge (Psych 240 Lecture, 10-15-14), was mostly intact. Numerous studies of HM across 30 years illustrated the importance of the hippocampus and amygdala in storing and retrieving explicit memories. (Ogden and Corkin,…

What are Neurotransmitters? The functions of the brain rely heavily on a complex system of communication. The brain’s process of communication is supported by a series of cells called Neurons which submit chemical charges known as Neurotransmitters. Neurons are the foundation for the brain’s functions and consist of three basic parts such as the Cell Body, Dendrites and Axons. The chemical transmissions from Neurotransmitters are the product of messages being communicated from one Neuron to the…

#2 Describe in detail the structure and function of any of the following: the nervous system, the brain, the endocrine system. Include charts with you description if you desire. Simple moments, decisions or reactions all have one thing in common, the brain. The brain is the control center for human’s entire body, giving signals at all times on what to do or how to respond. Nerves that connect your body to the brain are responsible for gather information to give to the spinal cord to give to…

This film investigates the behaviours of someone with brain damage who suffers memory loss. On her father's birthday, Lucy and her father were involved in a serious car crash. This left her with anterograde amnesia and leads her to believe that it is October the 13th every day. Lucy ends up watching a video of her life every morning to fill her in on the details she cannot remember, allowing her to live life. Memory is commonly described as a group of related and interacting processes that…

Cells originating from the dentate gyrus normally take 2 weeks before neurites reach their target areas in the CA3 region of the hippocampus, and 4-7 weeks before they become integrated into the hippocampal network. Immature neurons are especially sensitive to the local environment during this critical period. To this end, Verret, et al. evaluated the survival rate for newborn hippocampal…

Introduction Temporal lobe epilepsy is the most common type of epilepsy in adults, affecting approximately 1% of the general population. It is formally classified as neuronal misfiring in the mesial temporal lobes causing spontaneous, recurring seizures. In this review, I will investigate how the use of optogenetics in temporal lobe epilepsy (TLE) reduces seizures and how it can help us understand the cell types and neuronal circuits that underlie seizure generation. The significance of the…
