This activity is how to dissect the brain before a lesson.
Follow the description of the parts of the brain, and associated activities, in the brain lesson.
The brain will probably already be cut, with left and right sides separated.
If not, slice it in half.
Look at the parts: cortex, cerebellum, mid and hind brain, corpus callosum: see labelled image at www.biologycorner.com/anatomy/sheepbrain/brain_dissect07.jpg
Discuss the functions of the parts:
cortex: thinking, reasoning, also optic, motor and olfactory areas.
cerebellum: fine motor control
mid and hind brain: basic processes such as breathing, heart rate, sleeping, waking etc
The intact lamb brain can be stored in the fridge for days if covered in saran wrap to prevent drying out.
To see more cut the brain with a sharp penknife.
Cut parallel to the cut already made separating the left and right halves, but more lateral, to reveal the striatum and possibly the hippocampus.
Cut through part of the cortex to show the white and grey matter (the myelinated axons and the pinkish cell bodies).
