knowledge about “living things” but maintains knowledge about inanimate objects -Damage to hippocampus and related structures lead to conditions such as anterograde amnesia -Damage to the amygdala may result in remembering the details of an event but not the emotion content of the event -Episodic: episodic memory circuit-Semantic/Conceptual: cortical areas (but not episodic circuit)-Motor Skills: motor cortex and linked areas-Perceptual Priming: perceptual cortexEpisodic Memory:memory for experiences-“I remember that bike ride we took 10 years ago. It was a beautiful morning in spring…”-Memory for events that happened to meEpisodic Memory Circuit and Other Brain Areas Involved in Memory-Psychologists and neuroscientists increasingly think of the brain in terms of networks or circuits rather than distinct processing centersEssentially important for episodic event memories because they involve many different kinds of information-Involve many other parts of the brain (not just the hippocampus)-Experiences are coded in diverse brain areas and link togetherEntorhinal Cortex: crucial part of parahippocampal cortex; may bind different components of an experience together and link them to the hippocampusHippocampus: registers new memories and keeps track of them during consolidationAmygdala: especially involved in emotions of fear and disgustThalamus: another part of the episodic circuit that plays a role in sensory processing Consolidation and the Hippocampus:-Consolidation: the process that transforms new memories from a fragile state, in which they can be disrupted, to a more permanent state, in which they are resistant to disruption Newer memories are linked to the Episodic Memory Circuit (hippocampus keeps track of them)-Memories take years to “settle down” in the brainEvidence of transient and long-term amnesiaRecent memories are lost more easily and may never come back after severe trauma Ex: EP could remember older memories (20 years ago) but not recent ones from right before brain damage

Amnesia as a Normal Part of Memory:-Adult Memory: we remember only some of what has happened to us, forgetting is a normal even desirable feature of memoryChildhood Amnesia-We remember little of what happened to us in the first few years of lifeHowever, two and three year olds do remember things for weeks/monthsChild Amnesics with Brain Damage:-Loss of hippocampal structures on both sides was thought likely to cause severe mental retardation -However, children functioned quite well in school despite loss of episodic memory-Real life problems of the Amnesic Kids:Can’t find their way around familiar placesCan’t keep track of schedulesCan’t remember events, people, conversations, TV programsCan’t be left without supervision because of these problemsCan learn in school:Good language, can read, write and spellNormal vocabulary and comprehension test scores-How is this possible?

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
