Amygdala. Yes, I am tiny, but don't underestimate me based on size, I do a whole lot! What is the hippocampus and what does it do? Hippocampus: Anatomy and functions. As the severity (intensity, duration) of stress increases, alterations in neurochemicals, synaptic plasticity, neural activity, cytoarchitecture, and neurogenesis occur in the hippocampus that can influence subsequent cognitive functions, such as learning and memory, and contribute to psychopathologies. The neocortex does this by doing the exact opposite of what the hippocampus does - it ensures that neurons do not fire together. Hippocampus is the Latin word for seahorse. The hippocampus is the part of the brain that is involved in forming, organizing, and storing memories. Hippocampus. It is responsible for the process of transferring the data from the short-term into long-term memory.
The hippocampus has a unique shape, similar to that of a horseshoe. The limbic system is the highest part of the subcortical structures . 5. Because glial cells are very important to support the function of neurons, we wanted to know if glial cells were also affected by eating a high-fat-and-sugar diet. His hippocampus appeared entirely nonfunctional because the remaining 2 cm of hippocampal tissue appeared atrophic and because the entire entorhinal cortex, which forms the major sensory input to the hippocampus, was destroyed.

Answer: Hippocampal Formation - a set of limbic (not Neo) cortical structures in the medial temporal lobe of the brain that are predominantly involved with spatial navigation, learning, and memory--especially memory of events (episodic memory) and facts (semantic memory). The dentate gyrus of the hippocampal formation generates new granule neurons throughout life. This is often referred to as "neural desynchronisation . It has a very important job involving memories. What does the hippocampus do for memory? Luckily, the seizures did go away — but so did his long-term memory! For example, memorizing a speech uses declarative memory.
