THIS WEEK’S QUESTION!
Every Sunday, a question will be asked about one of the images from the past week. Be the first to answer correctly, and your blog will be promoted on Monday’s image post and Biocanvas’s main site!
Neurogenesis, the birth of new neurons, occurs throughout adulthood in two locations of the brain. One of these locations is in the hippocampus, which is responsible for processing memories and aiding in learning. If neurogenesis occurs throughout life in this area, then one would expect the hippocampus to increase continuously in size. This, however, is not the case.
How does the hippocampus remain relatively the same size while still having active sites of new cell genesis?
Answer: Present cells die at an equal rate to the generation of new cells, resulting in a net gain of approximately no new cells.
over it
when the music stops
and all there is left is us
we’ll make eye contact
to decide if there lies trust
“lies” and “trust” in the same line?
we know which one comes first
but when the lie comes through, and we’ve spent our trust
we will never be reimbursed
as trust is priceless
there is always cost, but only sometimes cause
for lies
sometimes lying is not in what you say
but there in what you hide
so when the music stops
and all there is left is looking in each other’s eyes
“lies” and “trust” can be in the same line
but which comes first is for you to decide.
…
Goodbye,
