what is sexual selection
where females apply more strategy to their behaviour, such as in peacocks, where females have a preference for big tails, leading to males taking more care of their feathers.

Medial
If an area of the brain is to one side of the brain, it is thought to be…
Lateral
What does superior mean in terms of brain location
near the top
what does inferior mean in terms of brain location
near the bottom
why do humans have bigger brains
1) they evolved.
2) they have more folds, meaning it has a greater surface area.
function of the frontal lobe
movement, inhibitions and control
function of the occipital lobe
visual processing
function of the temporal lobe
object/face recognition (who someone/what something is) and informational processing
function of the parietal lobe
perception of the body, attention and where things are (spatial attention)
function of the cerebellum
balance, motor planning and learning, double checking what you are doing is what is expected.

the brain is contained in a sac, and is designed to protect and nourish the brain, it provides an exchange medium between the blood and brain
ventricular system
Hollow caverns filled with cerebrospinal fluid, which acts as a shock absorber for the brain stem.
Lateral ventricles
two ventricals that are lateralised
third and fourth ventricals
third and fourth holes when coronally slices (sideways
brain slicing
- Horizontal plane - Rostral (front) to caudal (back)
- Sagittal plane - split the hemispheres
- Coronal plane - front to back
