Hippocampus Thomas Henry Huxley and Richard Owen, satirised as the Great Hippocampus Question. The term hippocampus minor fell from use in anatomy textbooks, and was officially removed in the Nomina Anatomica of 1895. Today, the structure is just called the hippocampus, with the term "Cornu Ammonis" surviving in the names of the hippocampal subfields CA1-CA4. The term "limbic system" was introduced in 1952 by Paul MacLean to describe the set of structures that line the edge of the cortex (Latin "limbus" meaning "border"): These include the hippocampus, cingulate cortex, olfactory cortex, and amygdala. Paul MacLean later suggested that the limbic structures
Prenatal memory the neurotoxic effects (harm to nerve cells) of prenatal methamphetamine exposure on brain development, as well as on cognitive functioning. Children exposed to meth in utero scored lower on key measures of memory performance, including attention, verbal memory and long term spatial memory. The reduced size of brain structures associated with memory and attention was also noted through magnetic resonance imaging (MRI), a process used to produce images of the brain for observation. For example, those with prenantal meth exposure had, on average, a smaller hippocampus (a brain structure involved in many things, including memory) than control participants. This reduction
