What's the difference between stratum and striatum?
Stratum
Definition:
(n.) A bed of earth or rock of one kind, formed by natural causes, and consisting usually of a series of layers, which form a rock as it lies between beds of other kinds. Also used figuratively.
(n.) A bed or layer artificially made; a course.

(20) Moisture on the skin was shown to increase the discharge to a standard stimulus, probably by its softening effect on the stratum corneum.
Striatum
Definition:
(n.) The corpus striatum.
Example Sentences:
(1) At 24 or 48 hours after ischemia, 63Ni, 99TcO4, and 22Na were preferentially concentrated in the damaged striatum and hippocampus, whereas 65Zn, 59Fe, 32PO4, and 147Pm did not accumulate in irreversibly injured tissue.
(2) When given chronically over 6 weeks the advantages of adding benserazide (50 mg kg-1 day-1) to levodopa (40 mg kg-1 day-1) were less marked and although more dopamine was present in the striatum than with levodopa given alone (200 mg kg-1 day-1) there was no evidence of any increase in its metabolites (HVA and DOPAC) and therefore of its turnover and utilisation.
(3) The effects of quinpirole and sulpiride on dopamine (DA), dihydroxyphenylacetic acid (DOPAC) and accumulation of dihydroxyphenylalanine (DOPA) after inhibition of DOPA decarboxylase were determined for the striatum and tegmentum of 11- and 17-day-old rat pups.
(4) We report that kainic acid lesions of the posterior corpus striatum, which preferentially spare fibers of passage while destroying striatopallidal neurons, produce a stimulus-sensitive movement pattern in rats that has a highly specific sensory trigger.
(5) The response of adenylate cyclase to GTP and to dopamine (DA) was investigated in synaptic plasma membranes isolated from rat striatum injected with pertussis toxin, which inactivates the inhibitory guanine nucleotide-binding regulatory protein (Ni) of adenylate cyclase.
