Size and behaviour Flashcards
1
Q
neuroethology
A
comparing brain size across species
2
Q
allometry
A
size of organism relates to characteristics
3
Q
residual brain size
A
more brain size than would be predicted for an organisms body size
4
Q
human evolution
A
- body size inc 50% but brain 250%
- skull change shape
- shown by tools becoming more advanced
- microcephalin involved in increased brain size increased in frequency as humans evolved
5
Q
principle of proper mass
A
size of neural structure reflects behaviour complexity
6
Q
motor map location
A
pre central gyrus
7
Q
sensory map location
A
post central gyrus
8
Q
map over representation
A
- face and hands
- lots of sensory neurones
9
Q
IQ and cortical thickness correlation
A
none
10
Q
bird evidence for size and behaviour
A
- hippocampus larger in birds that store seed
- HVC larger in birds with more complex behaviour
11
Q
monkey evidence for size and behaviour
A
- residual neocortex volume larger in deceptive behaviour
- cerebral cortex thicker in monkeys part of larger groups
