DIFFERENCES BETWEEN MAN & RABBIT -

S.NO. 1.	MAN Brain round	RABBIT Elongated
2.	Olfactory lobes, embeded in cereberum	Some what clear
3.	Olfactory lobes solid	Hollow
4.	Rinocoel absent	Present
5.	Corpora straita less developed	More developed
6.	Broca area less developed	More developed
7.	Spinal nerve 31 pairs	37 pairs
8.	Cauda aquina absent	Present
9.	Choroid plexus 5	2

SPECIAL POINTS -

Andrew V. Schally & Roger C. L. Guillemin discovered Release Factor (RF) from hypothalamus.
Optic chiasma mainly connected to steroscopic vision.
If spinal cord & spinal nerves are exposed, this condition is spinal bifida.
Due to absence of myelin sheath krab's disease or mentally dullness is occured.
Cranial nerves enter into geniculate ganglia.
Telencephalone of embryonic brain forms cerebrum & olfactory lobe.
Cerebral reflex is not immediate e.g. watering of mouth.
EEG - In closed eyes position, a-waves are given at the rate of 8-12 cycle / sec. In dream b & gwaves are given at the rate of 1-4 cycle/sec. In sleep delta waves are given.
Neurology - Study of structure, function & diseases of the nervous system.
Neurotoxin - A poison destruction to nervous system.
