In cephalopods the optic glands (OG) form a pair of oval organs located at the posterior edge of the optic brain tract, above the hilum of the
optic lobes (Boycott & Young 1956).
To obtain intact vesicles with higher purity, freshly dissected
optic lobe tissue was further fractionated by continuous glycerol density gradient centrifugation (Fig 1A).
To test the absorption and final concentration of T-817 within the cephalopod nervous system, the
optic lobes of control and fed squid were studied.
2+] in synaptosomes isolated from squid
optic lobe.
Dopamine modulates synaptic activity in the
optic lobes of cuttlefish, Sepia officinalis.
A frontal filament tract connects each frontal filament to its adjacent
optic lobe neuropil [ILLUSTRATION FOR FIGURES 5, 6B OMITTED].
Sections were de-waxed, incubated in anti-CE (cloned peptide sequence from squid
optic lobes, designated 25U2, raised in rabbit; 1:1000 dil.
The rate of protein synthesis by the synaptosomal fractions prepared from the
optic lobe was determined according to routine methods (1).
Squid
optic lobe membranes were incubated for 30 min on ice with various concentrations of CHAPS and then centrifuged at 43,000 rpm (100,000 x g) for 30 min.
Polysomes purified from the synaptosomal and microsomal fractions of squid
optic lobe actively synthesize proteins when supplemented with the supernatant fraction from a rabbit reticulocyte lysate.
Finally, I will study divergence in the visual system, beyond opsins, using comparative transcriptomics of the retina and the brain s
optic lobes.
Fossils reveal that dinosaurs often had very large eyes and sizable
optic lobes in their brains.
