hypocanthus

I heard and wrote this spelling ... hypocanthus, has something to do with the brain

Googled and discovered that this spelling is probably the same thing as hippocampus

Both referred to the same definition.  And both could be spoken/heard in the same way.

... the portion of the cerebral hemisphers in basal medial part of the temporal lobe. This part of the brain is important for learning and memory . . . for converting short term memory to more permanent memory, and for recalling spatial relationships in the world about us.

Now the other imagery that came with this was a dozen plus red laser dots scouring a dark shape, they did not settle anywhere, just kept moving on and beyond it.

Please recall I do work with people with dementia so there may be a link there when interpreting this.

Also, note that God often uses imagery I am familiar with to give structure to what he os trying  to share about a matter of his heart.  It must therefore apply, in that context to people generally, including his people, and me.

So to repeat, this vision revealed a bit of our brain responsible for converting short term memory to more permanent memory, and for recalling spatial relationships in the world about us.
