A Closer Look at the Rat Brain

Midsagittal slice of rat brain

 

Here is a closer midsagittal view of the rat brain. The blue lines represent where we can slice -- either in the forebrain or the hindbrain. If you want to see a cross-section of the forebrain, click on the right portion of the image. If you'd rather see the hindbrain, click on the left part of the image.

A Closer Look at the Cat Brain

A Closer Look at the Monkey Brain

The Human Hindbrain

Cross-Section of the Human Hindbrain

Now we are looking at a cross-section of the hindbrain of a human.

Can you tell which structures are visible? Do you see the convoluted material that is dark purple? That is the cerebellum. What do you think is the round, off-white structure in the middle? Look at this picture for a hint:

Human brain with brainstem and cerebellum labelled

 

Hopefully you can see now that the round, off-white structure is the brainstem.

The Human Forebrain

Coronal Section of the Human Forebrain

Now we are looking at a coronal section of the forebrain of a human.

What is the outer groove-like material? What are the inner structures?

This image is a good illustration of the cerebral cortex at the frontal lobe of the brain. The dark purple that looks like an outline is gray matter. The light purple inside the dark purple is white matter. You can also see the body of the corpus callosum, which is the structure connecting the two hemispheres of the brain. The white elliptical openings within the brain are ventricles, which are fluid-filled cavities that serve to cushion and protect the brain.

The Role of Smoking Cigarettes in the Education of a Young Jew

Jody Cohen

1.
A dime and a quarter in the slot and out
slides a pack of Lucky Strikes.
It fits perfectly in her palm.
She walks past the kiddie pool, where diapers hang to the chubby backs of knees,
past women in white swinging invisible rackets that make green balls sing.
Up past the pool with diving boards at two levels and
decks of seasonal rooms laid out in verticals like a game of solitaire.
Until finally she climbs the last hill and there is
no one.

She opens the Lucky Strikes and lights one, then another and another,
experimenting with how to do it until suddenly she’s
swaying in the buzzing morning heat.
She lands on her back. The grass is soft, the air stale.
Last night she’d flirted with Kurt, a big-headed blond boy who
wore a cross around his neck and planned to be a minister.
She would kiss him three times.
Three cigarettes.


2.
Rikki is tall, broad-shouldered, with hair falling over
one eye,
a sardonic twist to her mouth.
She is a year ahead of me in school, but
on Wednesday nights we meet
in the girls’ bathroom

during Hebrew School.

“6 million Jews…”
The teacher’s accented voice, her
high-waisted flowery dress, her
tongue distended with her passion—
grate on me.

The sinks are low

enough for us to elbow lean

Midsagittal Slice

A Midsagittal View: Right Down the Middle!

 

Group of sliced brains

 

The picture above shows the midsagittal view of a human, monkey, and cat brain. Essentially we have cut straight down the middle of the brains, separating them into two halves, or hemispheres. Can you visualize that? If you need a reminder of directional terminology, click here.
