OCEANO 1 Lecture Notes - Lecture 27: Cortisol, Axon Terminal, Cyclic Adenosine Monophosphate
Document Summary
Which parts of the brain are involved in memory? (anatomy) Part of this function is hippocampal involvement in the detection of new events, places and stimuli. The hippocampus also encodes emotional context from the amygdala. This is partly why returning to a location where an emotional event occurred may evoke that emotion. There is a deep emotional connection between episodic memories and places. Plasticity within the lateral amygdala (la) is essential for auditory conditioned fear memories. We think of several types of memory: short-term and long-term, reflexive and declarative. Processing for different types of memory appears to take place through different pathways. With noninvasive imaging techniques such as mri and pet scans, researchers have been able to track brain activity as individuals learned to perform tasks. Memories are stored throughout the cerebral cortex in pathways known as memory traces. Some components of memories are stored in the sensory cortices where they are processed.
