Neural Circuit for Explicit Memories

What is the first region(part of explicit memory) that is affected by Alzheimer's

Entorhinal cortex

Parahippocampal cortex

Receives connections from parietal lobe (dorsal stream) therefore is in charge of visuospatial memory

Perirhinal cortex

Receives connections from temporal lobe (ventral stream) and is this is charge of visual object memory

Entorhinal cortex

Receives info from both parahippocampal and perirhinal regions; integrative fiction; first area to see cell death in Alzheimer's ( funnels into hippocampus)
