AVP is excitatory in the ventral hippocampus, either directly or by potentiation of glutamatergic responses. An inhibitory effect has been observed in AVP may be involved in the formation of long-term potentiation and thus learning and memory. However, AVP is proconvulsive, may augment the formation of dmg tolerance and dependence, and affects cardiovascular regulatory processes.

The pathologic hallmarks of the disease in the brain include neurofibrillary tangles and neuritic plaques made up of various proteins, which result in a shortage of the neurotransmitter acetylcholine. These are primarily located in brain regions involved in learning, memory, and emotional behaviors such as the cerebral cortex, hippocampus, basal forebrain, and amygdala.11...

In contrast to LTP, LTD is induced by low-frequency stimulation. This causes the selective activation of PP2B (calcineurin), which maintains inhibitor-1 in its dephos-phorylated state. Several studies, including those using inhibitor-1 knockout mice and transgenic mice expressing a constitutively active form of inhibitor-1, demonstrate that the control of PP1 activity by inhibitor-1 in the hippocampus affects neuronal plasticity and learning and memory.

CA3 pyramidal neurons receive the mossy fiber input from the granule neurons of the dentate gyrus. This connection is part of the 3-cell circuit of the hippocampus that is believed to be involved in learning and memory. 

Estradiol also induces synapses in the hippocampus and this contributes to enhanced capacity for learning and memory that is dependent on the hippocampus [13]. Estradiol exerts many other nonreproductive actions on the brain, such as fine motor coordination, seizure susceptibility, mood, protection from ischemic damage. Many of these actions occur in brain regions that show little, if any, nuclear estrogen receptors, and it seems likely that the nongenomic estrogen receptor described above may be involved [13].
