Question

how are dolphin brain sturctures and human brain structures analogous?

Answer 1

The main features in the cetacean brain which differ from land mammals are:

- a thin neocortex (about 1.5 mm, compared to 2.9 mm in humans)
- rather uniform structure of the cortex
- low degree of differentiation between cortical layers and cells
- massive development of the (phylogenetically older) layers I and VI
- poor development of layers II, III and IV (which are well developed in land mammals)
- the neurons have relatively few primary dendrites and these are weakly branched.

Answer 2

right but what structures are analogous, like perform the same tasks. do they have an associations area like humans?

Answer 3

i dunno im looking it up on the internet, but i kinda like ur question :)
theyre interesting

Answer 4

hehe thankss

Answer 5

their brains are pretty similar in size
but dolphins slightly larger


Human brains appear to be composed of two mirror-symmetric
dissimilar hemispheres.

Dolphin brains appear to be composed of two similar sub-brains,
each of which has two hemispheres,
so Dolphins might be said to have 4-lobed brains
that might be used to experience Many-Worlds.

Answer 6

WOW DOLPHINS ARE SMARTER THAN HUMANS!!!

Answer 18

in my opinion i feel as if that because the dolphins brain is larger doesnt mean its smarter, its jsut used to store different kinds of information
