Those in their first episode of a psychotic illness would be less likely to show such impairment, since their right hippocampi would be normal.
After effective psychotherapy, however, no volume changes were found in the smaller hippocampi.
Note that simply tetanizing both hippocampi was without effect.
However, observations that verbal memory impairment is more severe with bilateral hippocampal lesions compared to unilateral lesions indicates that both hippocampi play a role in verbal memory.
In addition, perhaps more subtle analyses will unveil processing differences in the hippocampi of mammals and reptiles, and many of the differences may be quantitative rather than qualitative.
Its floor presents the following parts: the hippocampus, the fimbria hippocampi, the collateral eminence, and the choroid plexus.
This is supported by studies in which lesions are applied to rat hippocampi at different times after learning.
For example, in the rat, the two hippocampi look similar to a pair of bananas, joined at the stems.
