Each optic lobe
is as the synthesis of a large cavity, both sides are combined into the mesencephalon cavity, the boundary is not obvious, and the cavity is back to the fourth ventricle.
Abbreviations: 3-ABA, 3-aminobenzamide; ADP-ribose, ADPR, adenosine diphosphate ribose; CNS, central nervous system; LTD, long-term depression; LTM, long-term memory; LTP, long term potentiation; NMDA, N-methyl-D-aspartate; Oct-actin, Octopus actin; OL, optic lobes
; ON, optic nerves; PARP, poly (ADP-ribose) polymerase; PARP-1, poly(ADP-ribose) polymerase 1; STM, short-term memory; SubE, subesophageal mass; SupraE, supraesophageal mass; VL, vertical lobe; VPARP, vault-associated PARP.
The telson has 6 or 7 spines (or setae) and reaches the anterior margin of the optic lobes
. Lateral appendages have setae.
The OG is located over the optic stalk close to the optic lobe
, it is covered by a fine connective layer, and has an elongate shape.
The transverse fissure separated the caudal pole of the cerebral hemispheres from the cerebellum dorsally and extended to separate the optic lobe
laterally and ventrally (Fig.
Using advances in the purification of SVs from rat brain (Huttner et al., 1983), we optimized an SV isolation protocol for squid (Logilo pealei [LeSueur, 1821]) optic lobe
in this study to obtain a highly pure and intact SV population for biochemical and ultrastructural studies.
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.
Dowdall and Simon (26) and Matsumura (27) showed that Ch is transported by synaptosomes isolated from squid optic lobes
. The uptake of Ch by synaptosomes isolated from cuttlefish optic lobe
exhibited similar characteristics, including a high initial rate of accumulation and sensitivity to HC-3.
Rich at the Museum of Victoria in Melbourne, and their co-workers have discovered a chicken-sized dinosaur with unusually large eyes and optic lobes
of the brain, suggesting that this animal may have been equipped to survive the polar winter's long period of darkness rather than simply migrate away from it.
Two major parts of the nervous system, the optic lobes
and the nervous system of the arms, lie outside the brain capsule.
Sections were de-waxed, incubated in anti-CE (cloned peptide sequence from squid optic lobes
, designated 25U2, raised in rabbit; 1:1000 dil.), and then in biotinylated horse anti-rabbit secondary antibody, followed by avidin-bound microperoxidase (ABC method, Vector), and finally reacted with the chromogen, 3-amino-9-ethylcarbazole (AEC).
In most decapods with stalked eyes, the optic neuropiles are located within the eyestalks in optic lobes
that form the most anterior parts of the brain.
