Comparative analysis of calcium-binding protein-immunoreactive neuronal populations in the auditory and visual systems of the bottlenose dolphin (Tursiops truncatus) and the macaque monkey (Macaca fascicularis)

Functional imaging of dolphin brain metabolism and blood flow

“…Modern morphomolecular studies of fixed material have begun to reveal information relative to the neurochemistry of some regions of the dolphin brain (cf. Hof et al, 1995;Glezer et al, 1998;Manger et al, 2003;Manger et al, 2004). However, noninvasive means of investigating this large and highly organized brain in the living animal have been quite limited and there is little understanding of the neurotransmitter and neuromodulator distribution in the dolphin brain as a whole.…”

Neuroanatomy of the killer whale (Orcinus orca) from magnetic resonance images

“…As there is a 55-60 million year divergence between cetaceans and the phylogenetically closest group, the artiodactyls, odontocete brains represent a blend of early mammalian and uniquely derived features (Ridgway, 1986(Ridgway, , 1990Glezer et al, 1988;Manger et al, 1998). Differences between cetacean and other mammalian brains of similar size have been found in cytoarchitecture and histochemistry (Garey et al, 1985;Garey and Leuba, 1986;Glezer et al, , 1992aGlezer et al, , 1992bGlezer et al, , 1993Glezer et al, , 1998Hof et al, 1992Hof et al, , 1995Hof et al, , 1999Hof et al, , 2000, cortical surface configuration (Jacobs et al, 1979;Morgane et al, 1980;Haug, 1987), and subcortical structural morphology (Tarpley and Ridgway, 1994;Glezer et al, 1995aGlezer et al, , 1995b.The brains of a few cetacean species, particularly the bottlenose dolphin (Tursiops truncatus), have been studied relatively extensively. This is primarily due to the fact that bottlenose dolphins are popular in captivity and have been the focus of many long-term field studies.…”

Neuroanatomy of the common dolphin (Delphinus delphis) as revealed by magnetic resonance imaging (MRI)

“…As there is a 55-60 million year divergence between cetaceans and the phylogenetically closest group (the artiodactyls), odontocete brains represent a blend of early mammalian and uniquely derived features (Ridgway, 1986;Glezer et al, 1988;Ridgway, 1990;Manger et al, 1998). The differences between cetacean and other mammalian brains of similar size have been noted at the level of cortical cytoarchitecture and histochemistry (Garey et al, 1985;Garey and Leuba, 1986;Glezer et al, , 1992aGlezer et al, , b, 1993Glezer et al, , 1998Hof et al, 1992Hof et al, , 1995, cortical surface configuration (Jacobs et al, 1979;Morgane et al, 1980;Haug, 1987), and subcortical structural morphology (Tarpley and Ridgway, 1994;Glezer et al, 1995a, b). These differences are also manifest during ontogeny (Oelschlager and Buhl, 1985;Buhl and Oelschlager, 1988;Oelschlager and Kemp, 1998).…”
