GABA as a Putative Neurotransmitter in the Optic Lobes of the Crab HEMIGRAPSUS NUDUS
… of GABA as a putative neurotransmitter in the optic lobes of the crab <em>Hemigrapsus nudus, </em></p> <p>light microscope autoradiography ( LM ARG ), light microscope immunocytochemistry ( LM ICC ), and neurochemical techniques were employed. ARG labeling of <sup>3</sup>H-GABA was observed …

The Localization of GABA-Like Immunoreactivity in the Optic Lobe Neuropils and Optic Tracts of the Cockroach Leucophaea Maderae
… pattern of electrical output measured from the optic nerve in L. maderae. Considering the circadian oscillator for L. maderae has been localized to the optic lobes of the brain, the discovery of GABA-like immunoreactivity in the optic lobes and optic tract could be an important first step in …

Exploring the Cephalopod Brain: Towards Mapping the First Whole Brain Connectome and Whole Animal Projectome of a Pygmy Squid
… connectomic atlases for the cephalopod optic lobes and brain. To obtain synaptic-resolution volumes of neural tissue, the primary technique used was Volume Electron Microscopy (vEM), specifically Enhanced Focused Ion Beam Scanning Electron Microscopy (eFIBSEM) and Multibeam Scanning …

THE CRAYFISH VISUAL SYSTEM: INTRACELLULAR STUDIES AND MORPHOLOGIES OF IDENTIFIED INTERNEURONS
… intracellular recordings to be made from the optic lobes of the crayfish compound eye. Sustaining fibers (SFs) were impaled with lucifer yellow electrodes near their entrance to the second optic ganglion or Medulla (where the SFs originate). Corneal receptive fields were determined and the SFs …

Palaeobiology and flight capacity of volant palaeognaths (Pan-Palaeognathae: Lithornithidae): implications for the common ancestor of extant palaeognaths and early crown birds
… a moderately enlarged telencephalon and enlarged optic lobes. In Chapter 4, I redescribe the L. vulturinus neotype, providing new information gleaned from CT scans of the specimen, and additionally provide a description of a new L. vulturinus fossil specimen from near the type locality. While this …

Spectral and ocellar inputs to honeybee motion-sensitive descending neurons
… studies showed that the motion detectors in the optic lobes have a secondary response peak in the UV region of the spectrum suggesting that there may be more than one type of photoreceptor involved in the optomotor response. Thus in this thesis, I investigate the neural basis of motion and …

Oviraptorosauria: Morphology, Phylogeny, and Endocranial Evolution
… the olfactory bulbs, cerebrum, pituitary space, optic lobes, cerebellum, and brain stem. These partitions are then used to evaluate how these different regions of the "brain" are evolving. The division of the endocranial cast into partitions is a novel approach to studying endocranial morphology. …
